It +complements the GNU General Public License, which is a copyleft +license designed for free software. + +We have designed this License in order to use it for manuals for free +software, because free software needs free documentation: a free +program should come with manuals providing the same freedoms that the +software does. But this License is not limited to software manuals; +it can be used for any textual work, regardless of subject matter or +whether it is published as a printed book. We recommend this License +principally for works whose purpose is instruction or reference. + +@item +APPLICABILITY AND DEFINITIONS + +This License applies to any manual or other work, in any medium, that +contains a notice placed by the copyright holder saying it can be +distributed under the terms of this License. Such a notice grants a +world-wide, royalty-free license, unlimited in duration, to use that +work under the conditions stated herein. The ``Document'', below, +refers to any such manual or work. Any member of the public is a +licensee, and is addressed as ``you''. You accept the license if you +copy, modify or distribute the work in a way requiring permission +under copyright law. + +A ``Modified Version'' of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. + +A ``Secondary Section'' is a named appendix or a front-matter section +of the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document's overall +subject (or to related matters) and contains nothing that could fall +directly within that overall subject. (Thus, if the Document is in +part a textbook of mathematics, a Secondary Section may not explain +any mathematics.) The relationship could be a matter of historical +connection with the subject or with related matters, or of legal, +commercial, philosophical, ethical or political position regarding +them. + +The ``Invariant Sections'' are certain Secondary Sections whose titles +are designated, as being those of Invariant Sections, in the notice +that says that the Document is released under this License. If a +section does not fit the above definition of Secondary then it is not +allowed to be designated as Invariant. The Document may contain zero +Invariant Sections. If the Document does not identify any Invariant +Sections then there are none. + +The ``Cover Texts'' are certain short passages of text that are listed, +as Front-Cover Texts or Back-Cover Texts, in the notice that says that +the Document is released under this License. A Front-Cover Text may +be at most 5 words, and a Back-Cover Text may be at most 25 words. + +A ``Transparent'' copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed of +pixels) generic paint programs or (for drawings) some widely available +drawing editor, and that is suitable for input to text formatters or +for automatic translation to a variety of formats suitable for input +to text formatters. A copy made in an otherwise Transparent file +format whose markup, or absence of markup, has been arranged to thwart +or discourage subsequent modification by readers is not Transparent. +An image format is not Transparent if used for any substantial amount +of text. A copy that is not ``Transparent'' is called ``Opaque''. + +Examples of suitable formats for Transparent copies include plain +ASCII without markup, Texinfo input format, La@TeX{} input +format, SGML or XML using a publicly available +DTD, and standard-conforming simple HTML, +PostScript or PDF designed for human modification. Examples +of transparent image formats include PNG, XCF and +JPG@. Opaque formats include proprietary formats that can be +read and edited only by proprietary word processors, SGML or +XML for which the DTD and/or processing tools are +not generally available, and the machine-generated HTML, +PostScript or PDF produced by some word processors for +output purposes only. + +The ``Title Page'' means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, ``Title Page'' means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +The ``publisher'' means any person or entity that distributes copies +of the Document to the public. + +A section ``Entitled XYZ'' means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as ``Acknowledgements'', +``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' +of such a section when you modify the Document means that it remains a +section ``Entitled XYZ'' according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + +@item +VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + +@item +COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + +@item +MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +@enumerate A +@item +Use in the Title Page (and on the covers, if any) a title distinct +from that of the Document, and from those of previous versions +(which should, if there were any, be listed in the History section +of the Document). You may use the same title as a previous version +if the original publisher of that version gives permission. + +@item +List on the Title Page, as authors, one or more persons or entities +responsible for authorship of the modifications in the Modified +Version, together with at least five of the principal authors of the +Document (all of its principal authors, if it has fewer than five), +unless they release you from this requirement. + +@item +State on the Title page the name of the publisher of the +Modified Version, as the publisher. + +@item +Preserve all the copyright notices of the Document. + +@item +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. + +@item +Include, immediately after the copyright notices, a license notice +giving the public permission to use the Modified Version under the +terms of this License, in the form shown in the Addendum below. + +@item +Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document's license notice. + +@item +Include an unaltered copy of this License. + +@item +Preserve the section Entitled ``History'', Preserve its Title, and add +to it an item stating at least the title, year, new authors, and +publisher of the Modified Version as given on the Title Page. If +there is no section Entitled ``History'' in the Document, create one +stating the title, year, authors, and publisher of the Document as +given on its Title Page, then add an item describing the Modified +Version as stated in the previous sentence. + +@item +Preserve the network location, if any, given in the Document for +public access to a Transparent copy of the Document, and likewise +the network locations given in the Document for previous versions +it was based on. These may be placed in the ``History'' section. +You may omit a network location for a work that was published at +least four years before the Document itself, or if the original +publisher of the version it refers to gives permission. + +@item +For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve +the Title of the section, and preserve in the section all the +substance and tone of each of the contributor acknowledgements and/or +dedications given therein. + +@item +Preserve all the Invariant Sections of the Document, +unaltered in their text and in their titles. Section numbers +or the equivalent are not considered part of the section titles. + +@item +Delete any section Entitled ``Endorsements''. Such a section +may not be included in the Modified Version. + +@item +Do not retitle any existing section to be Entitled ``Endorsements'' or +to conflict in title with any Invariant Section. + +@item +Preserve any Warranty Disclaimers. +@end enumerate + +If the Modified Version includes new front-matter sections or +appendices that qualify as Secondary Sections and contain no material +copied from the Document, you may at your option designate some or all +of these sections as invariant. To do this, add their titles to the +list of Invariant Sections in the Modified Version's license notice. +These titles must be distinct from any other section titles. + +You may add a section Entitled ``Endorsements'', provided it contains +nothing but endorsements of your Modified Version by various +parties---for example, statements of peer review or that the text has +been approved by an organization as the authoritative definition of a +standard. + +You may add a passage of up to five words as a Front-Cover Text, and a +passage of up to 25 words as a Back-Cover Text, to the end of the list +of Cover Texts in the Modified Version. Only one passage of +Front-Cover Text and one of Back-Cover Text may be added by (or +through arrangements made by) any one entity. If the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + +@item +COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled ``History'' +in the various original documents, forming one section Entitled +``History''; likewise combine any sections Entitled ``Acknowledgements'', +and any sections Entitled ``Dedications''. You must delete all +sections Entitled ``Endorsements.'' + +@item +COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other documents +released under this License, and replace the individual copies of this +License in the various documents with a single copy that is included in +the collection, provided that you follow the rules of this License for +verbatim copying of each of the documents in all other respects. + +You may extract a single document from such a collection, and distribute +it individually under this License, provided you insert a copy of this +License into the extracted document, and follow this License in all +other respects regarding verbatim copying of that document. + +@item +AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an ``aggregate'' if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation's users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document's Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. + +@item +TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. + +If a section in the Document is Entitled ``Acknowledgements'', +``Dedications'', or ``History'', the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. + +@item +TERMINATION + +You may not copy, modify, sublicense, or distribute the Document +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense, or distribute it is void, and +will automatically terminate your rights under this License. + +However, if you cease all violation of this License, then your license +from a particular copyright holder is reinstated (a) provisionally, +unless and until the copyright holder explicitly and finally +terminates your license, and (b) permanently, if the copyright holder +fails to notify you of the violation by some reasonable means prior to +60 days after the cessation. + +Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + +Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, receipt of a copy of some or all of the same material does +not give you any rights to use it. + +@item +FUTURE REVISIONS OF THIS LICENSE + +The Free Software Foundation may publish new, revised versions +of the GNU Free Documentation License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. See +@uref{http://www.gnu.org/copyleft/}. + +Each version of the License is given a distinguishing version number. +If the Document specifies that a particular numbered version of this +License ``or any later version'' applies to it, you have the option of +following the terms and conditions either of that specified version or +of any later version that has been published (not as a draft) by the +Free Software Foundation. If the Document does not specify a version +number of this License, you may choose any version ever published (not +as a draft) by the Free Software Foundation. If the Document +specifies that a proxy can decide which future versions of this +License can be used, that proxy's public statement of acceptance of a +version permanently authorizes you to choose that version for the +Document. + +@item +RELICENSING + +``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any +World Wide Web server that publishes copyrightable works and also +provides prominent facilities for anybody to edit those works. A +public wiki that anybody can edit is an example of such a server. A +``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the +site means any set of copyrightable works thus published on the MMC +site. + +``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0 +license published by Creative Commons Corporation, a not-for-profit +corporation with a principal place of business in San Francisco, +California, as well as future copyleft versions of that license +published by that same organization. + +``Incorporate'' means to publish or republish a Document, in whole or +in part, as part of another Document. + +An MMC is ``eligible for relicensing'' if it is licensed under this +License, and if all works that were first published under this License +somewhere other than this MMC, and subsequently incorporated in whole +or in part into the MMC, (1) had no cover texts or invariant sections, +and (2) were thus incorporated prior to November 1, 2008. + +The operator of an MMC Site may republish an MMC contained in the site +under CC-BY-SA on the same site at any time before August 1, 2009, +provided the MMC is eligible for relicensing. + +@end enumerate + +@page +@heading ADDENDUM: How to use this License for your documents + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and +license notices just after the title page: + +@smallexample +@group + Copyright (C) @var{year} @var{your name}. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.3 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover + Texts.

It supports HTTP, HTTPS, and FTP protocols, as well as +retrieval through HTTP proxies. + + This chapter is a partial overview of Wget’s features. + + • Wget is non-interactive, meaning that it can work in the + background, while the user is not logged on. This allows you to + start a retrieval and disconnect from the system, letting Wget + finish the work. By contrast, most of the Web browsers require + constant user’s presence, which can be a great hindrance when + transferring a lot of data. + + • Wget can follow links in HTML, XHTML, and CSS pages, to create + local versions of remote web sites, fully recreating the directory + structure of the original site. This is sometimes referred to as + “recursive downloading.” While doing that, Wget respects the Robot + Exclusion Standard (‘/robots.txt’). Wget can be instructed to + convert the links in downloaded files to point at the local files, + for offline viewing. + + • File name wildcard matching and recursive mirroring of directories + are available when retrieving via FTP. Wget can read the + time-stamp information given by both HTTP and FTP servers, and + store it locally. Thus Wget can see if the remote file has changed + since last retrieval, and automatically retrieve the new version if + it has. This makes Wget suitable for mirroring of FTP sites, as + well as home pages. + + • Wget has been designed for robustness over slow or unstable network + connections; if a download fails due to a network problem, it will + keep retrying until the whole file has been retrieved. If the + server supports regetting, it will instruct the server to continue + the download from where it left off. + + • Wget supports proxy servers, which can lighten the network load, + speed up retrieval and provide access behind firewalls. Wget uses + the passive FTP downloading by default, active FTP being an option. + + • Wget supports IP version 6, the next generation of IP. IPv6 is + autodetected at compile-time, and can be disabled at either build + or run time. Binaries built with IPv6 support work well in both + IPv4-only and dual family environments. + + • Built-in features offer mechanisms to tune which links you wish to + follow (*note Following Links::). + + • The progress of individual downloads is traced using a progress + gauge. Interactive downloads are tracked using a + “thermometer”-style gauge, whereas non-interactive ones are traced + with dots, each dot representing a fixed amount of data received + (1KB by default). Either gauge can be customized to your + preferences. + + • Most of the features are fully configurable, either through command + line options, or via the initialization file ‘.wgetrc’ (*note + Startup File::). Wget allows you to define “global” startup files + (‘/usr/local/etc/wgetrc’ by default) for site settings. You can + also specify the location of a startup file with the –config + option. To disable the reading of config files, use –no-config. + If both –config and –no-config are given, –no-config is ignored. + + • Finally, GNU Wget is free software. This means that everyone may + use it, redistribute it and/or modify it under the terms of the GNU + General Public License, as published by the Free Software + Foundation (see the file ‘COPYING’ that came with GNU Wget, for + details). + + +File: wget.info, Node: Invoking, Next: Recursive Download, Prev: Overview, Up: Top + +2 Invoking +********** + +By default, Wget is very simple to invoke. The basic syntax is: + + wget [OPTION]... [URL]... + + Wget will simply download all the URLs specified on the command line. +URL is a “Uniform Resource Locator”, as defined below. + + However, you may wish to change some of the default parameters of +Wget. You can do it two ways: permanently, adding the appropriate +command to ‘.wgetrc’ (*note Startup File::), or specifying it on the +command line. + +* Menu: + +* URL Format:: +* Option Syntax:: +* Basic Startup Options:: +* Logging and Input File Options:: +* Download Options:: +* Directory Options:: +* HTTP Options:: +* HTTPS (SSL/TLS) Options:: +* FTP Options:: +* Recursive Retrieval Options:: +* Recursive Accept/Reject Options:: +* Exit Status:: + + +File: wget.info, Node: URL Format, Next: Option Syntax, Prev: Invoking, Up: Invoking + +2.1 URL Format +============== + +“URL” is an acronym for Uniform Resource Locator. A uniform resource +locator is a compact string representation for a resource available via +the Internet. Wget recognizes the URL syntax as per RFC1738. This is +the most widely used form (square brackets denote optional parts): + + http://host[:port]/directory/file + ftp://host[:port]/directory/file + + You can also encode your username and password within a URL: + + ftp://user:password@host/path + http://user:password@host/path + + Either USER or PASSWORD, or both, may be left out. If you leave out +either the HTTP username or password, no authentication will be sent. +If you leave out the FTP username, ‘anonymous’ will be used. If you +leave out the FTP password, your email address will be supplied as a +default password.(1) + + *Important Note*: if you specify a password-containing URL on the +command line, the username and password will be plainly visible to all +users on the system, by way of ‘ps’. On multi-user systems, this is a +big security risk. To work around it, use ‘wget -i -’ and feed the URLs +to Wget’s standard input, each on a separate line, terminated by ‘C-d’. + + You can encode unsafe characters in a URL as ‘%xy’, ‘xy’ being the +hexadecimal representation of the character’s ASCII value. Some common +unsafe characters include ‘%’ (quoted as ‘%25’), ‘:’ (quoted as ‘%3A’), +and ‘@’ (quoted as ‘%40’). Refer to RFC1738 for a comprehensive list of +unsafe characters. + + Wget also supports the ‘type’ feature for FTP URLs. By default, FTP +documents are retrieved in the binary mode (type ‘i’), which means that +they are downloaded unchanged. Another useful mode is the ‘a’ (“ASCII”) +mode, which converts the line delimiters between the different operating +systems, and is thus useful for text files. Here is an example: + + ftp://host/directory/file;type=a + + Two alternative variants of URL specification are also supported, +because of historical (hysterical?) reasons and their widespreaded use. + + FTP-only syntax (supported by ‘NcFTP’): + host:/dir/file + + HTTP-only syntax (introduced by ‘Netscape’): + host[:port]/dir/file + + These two alternative forms are deprecated, and may cease being +supported in the future. + + If you do not understand the difference between these notations, or +do not know which one to use, just use the plain ordinary format you use +with your favorite browser, like ‘Lynx’ or ‘Netscape’. + + ---------- Footnotes ---------- + + (1) If you have a ‘.netrc’ file in your home directory, password will +also be searched for there. + + +File: wget.info, Node: Option Syntax, Next: Basic Startup Options, Prev: URL Format, Up: Invoking + +2.2 Option Syntax +================= + +Since Wget uses GNU getopt to process command-line arguments, every +option has a long form along with the short one. Long options are more +convenient to remember, but take time to type. You may freely mix +different option styles, or specify options after the command-line +arguments. Thus you may write: + + wget -r --tries=10 http://fly.srk.fer.hr/ -o log + + The space between the option accepting an argument and the argument +may be omitted. Instead of ‘-o log’ you can write ‘-olog’. + + You may put several options that do not require arguments together, +like: + + wget -drc URL + + This is completely equivalent to: + + wget -d -r -c URL + + Since the options can be specified after the arguments, you may +terminate them with ‘--’. So the following will try to download URL +‘-x’, reporting failure to ‘log’: + + wget -o log -- -x + + The options that accept comma-separated lists all respect the +convention that specifying an empty list clears its value. This can be +useful to clear the ‘.wgetrc’ settings. For instance, if your ‘.wgetrc’ +sets ‘exclude_directories’ to ‘/cgi-bin’, the following example will +first reset it, and then set it to exclude ‘/~nobody’ and ‘/~somebody’. +You can also clear the lists in ‘.wgetrc’ (*note Wgetrc Syntax::). + + wget -X "" -X /~nobody,/~somebody + + Most options that do not accept arguments are “boolean” options, so +named because their state can be captured with a yes-or-no (“boolean”) +variable. For example, ‘--follow-ftp’ tells Wget to follow FTP links +from HTML files and, on the other hand, ‘--no-glob’ tells it not to +perform file globbing on FTP URLs. A boolean option is either +“affirmative” or “negative” (beginning with ‘--no’). All such options +share several properties. + + Unless stated otherwise, it is assumed that the default behavior is +the opposite of what the option accomplishes. For example, the +documented existence of ‘--follow-ftp’ assumes that the default is to +_not_ follow FTP links from HTML pages. + + Affirmative options can be negated by prepending the ‘--no-’ to the +option name; negative options can be negated by omitting the ‘--no-’ +prefix. This might seem superfluous—if the default for an affirmative +option is to not do something, then why provide a way to explicitly turn +it off? But the startup file may in fact change the default. For +instance, using ‘follow_ftp = on’ in ‘.wgetrc’ makes Wget _follow_ FTP +links by default, and using ‘--no-follow-ftp’ is the only way to restore +the factory default from the command line. + + +File: wget.info, Node: Basic Startup Options, Next: Logging and Input File Options, Prev: Option Syntax, Up: Invoking + +2.3 Basic Startup Options +========================= + +‘-V’ +‘--version’ + Display the version of Wget. + +‘-h’ +‘--help’ + Print a help message describing all of Wget’s command-line options. + +‘-b’ +‘--background’ + Go to background immediately after startup. If no output file is + specified via the ‘-o’, output is redirected to ‘wget-log’. + +‘-e COMMAND’ +‘--execute COMMAND’ + Execute COMMAND as if it were a part of ‘.wgetrc’ (*note Startup + File::). A command thus invoked will be executed _after_ the + commands in ‘.wgetrc’, thus taking precedence over them. If you + need to specify more than one wgetrc command, use multiple + instances of ‘-e’. + + +File: wget.info, Node: Logging and Input File Options, Next: Download Options, Prev: Basic Startup Options, Up: Invoking + +2.4 Logging and Input File Options +================================== + +‘-o LOGFILE’ +‘--output-file=LOGFILE’ + Log all messages to LOGFILE. The messages are normally reported to + standard error. + +‘-a LOGFILE’ +‘--append-output=LOGFILE’ + Append to LOGFILE. This is the same as ‘-o’, only it appends to + LOGFILE instead of overwriting the old log file. If LOGFILE does + not exist, a new file is created. + +‘-d’ +‘--debug’ + Turn on debug output, meaning various information important to the + developers of Wget if it does not work properly. Your system + administrator may have chosen to compile Wget without debug + support, in which case ‘-d’ will not work. Please note that + compiling with debug support is always safe—Wget compiled with the + debug support will _not_ print any debug info unless requested with + ‘-d’. *Note Reporting Bugs::, for more information on how to use + ‘-d’ for sending bug reports. + +‘-q’ +‘--quiet’ + Turn off Wget’s output. + +‘-v’ +‘--verbose’ + Turn on verbose output, with all the available data. The default + output is verbose. + +‘-nv’ +‘--no-verbose’ + Turn off verbose without being completely quiet (use ‘-q’ for + that), which means that error messages and basic information still + get printed. + +‘--report-speed=TYPE’ + Output bandwidth as TYPE. The only accepted value is ‘bits’. + +‘-i FILE’ +‘--input-file=FILE’ + Read URLs from a local or external FILE. If ‘-’ is specified as + FILE, URLs are read from the standard input. (Use ‘./-’ to read + from a file literally named ‘-’.) + + If this function is used, no URLs need be present on the command + line. If there are URLs both on the command line and in an input + file, those on the command lines will be the first ones to be + retrieved. If ‘--force-html’ is not specified, then FILE should + consist of a series of URLs, one per line. + + However, if you specify ‘--force-html’, the document will be + regarded as ‘html’. In that case you may have problems with + relative links, which you can solve either by adding ‘<base + href="URL">’ to the documents or by specifying ‘--base=URL’ on the + command line. + + If the FILE is an external one, the document will be automatically + treated as ‘html’ if the Content-Type matches ‘text/html’. + Furthermore, the FILE’s location will be implicitly used as base + href if none was specified. + +‘--input-metalink=FILE’ + Downloads files covered in local Metalink FILE. Metalink version 3 + and 4 are supported. + +‘--keep-badhash’ + Keeps downloaded Metalink’s files with a bad hash. It appends + .badhash to the name of Metalink’s files which have a checksum + mismatch, except without overwriting existing files. + +‘--metalink-over-http’ + Issues HTTP HEAD request instead of GET and extracts Metalink + metadata from response headers. Then it switches to Metalink + download. If no valid Metalink metadata is found, it falls back to + ordinary HTTP download. Enables ‘Content-Type: + application/metalink4+xml’ files download/processing. + +‘--metalink-index=NUMBER’ + Set the Metalink ‘application/metalink4+xml’ metaurl ordinal + NUMBER. From 1 to the total number of “application/metalink4+xml” + available. Specify 0 or ‘inf’ to choose the first good one. + Metaurls, such as those from a ‘--metalink-over-http’, may have + been sorted by priority key’s value; keep this in mind to choose + the right NUMBER. + +‘--preferred-location’ + Set preferred location for Metalink resources. This has effect if + multiple resources with same priority are available. + +‘--xattr’ + Enable use of file system’s extended attributes to save the + original URL and the Referer HTTP header value if used. + + Be aware that the URL might contain private information like access + tokens or credentials. + +‘-F’ +‘--force-html’ + When input is read from a file, force it to be treated as an HTML + file. This enables you to retrieve relative links from existing + HTML files on your local disk, by adding ‘<base href="URL">’ to + HTML, or using the ‘--base’ command-line option. + +‘-B URL’ +‘--base=URL’ + Resolves relative links using URL as the point of reference, when + reading links from an HTML file specified via the + ‘-i’/‘--input-file’ option (together with ‘--force-html’, or when + the input file was fetched remotely from a server describing it as + HTML). This is equivalent to the presence of a ‘BASE’ tag in the + HTML input file, with URL as the value for the ‘href’ attribute. + + For instance, if you specify ‘http://foo/bar/a.html’ for URL, and + Wget reads ‘../baz/b.html’ from the input file, it would be + resolved to ‘http://foo/baz/b.html’. + +‘--config=FILE’ + Specify the location of a startup file you wish to use instead of + the default one(s). Use –no-config to disable reading of config + files. If both –config and –no-config are given, –no-config is + ignored. + +‘--rejected-log=LOGFILE’ + Logs all URL rejections to LOGFILE as comma separated values. The + values include the reason of rejection, the URL and the parent URL + it was found in. + + +File: wget.info, Node: Download Options, Next: Directory Options, Prev: Logging and Input File Options, Up: Invoking + +2.5 Download Options +==================== + +‘--bind-address=ADDRESS’ + When making client TCP/IP connections, bind to ADDRESS on the local + machine. ADDRESS may be specified as a hostname or IP address. + This option can be useful if your machine is bound to multiple IPs. + +‘--bind-dns-address=ADDRESS’ + [libcares only] This address overrides the route for DNS requests. + If you ever need to circumvent the standard settings from + /etc/resolv.conf, this option together with ‘--dns-servers’ is your + friend. ADDRESS must be specified either as IPv4 or IPv6 address. + Wget needs to be built with libcares for this option to be + available. + +‘--dns-servers=ADDRESSES’ + [libcares only] The given address(es) override the standard + nameserver addresses, e.g. as configured in /etc/resolv.conf. + ADDRESSES may be specified either as IPv4 or IPv6 addresses, + comma-separated. Wget needs to be built with libcares for this + option to be available. + +‘-t NUMBER’ +‘--tries=NUMBER’ + Set number of tries to NUMBER. Specify 0 or ‘inf’ for infinite + retrying. The default is to retry 20 times, with the exception of + fatal errors like “connection refused” or “not found” (404), which + are not retried. + +‘-O FILE’ +‘--output-document=FILE’ + The documents will not be written to the appropriate files, but all + will be concatenated together and written to FILE. If ‘-’ is used + as FILE, documents will be printed to standard output, disabling + link conversion. (Use ‘./-’ to print to a file literally named + ‘-’.) + + Use of ‘-O’ is _not_ intended to mean simply “use the name FILE + instead of the one in the URL;” rather, it is analogous to shell + redirection: ‘wget -O file http://foo’ is intended to work like + ‘wget -O - http://foo > file’; ‘file’ will be truncated + immediately, and _all_ downloaded content will be written there. + + For this reason, ‘-N’ (for timestamp-checking) is not supported in + combination with ‘-O’: since FILE is always newly created, it will + always have a very new timestamp. A warning will be issued if this + combination is used. + + Similarly, using ‘-r’ or ‘-p’ with ‘-O’ may not work as you expect: + Wget won’t just download the first file to FILE and then download + the rest to their normal names: _all_ downloaded content will be + placed in FILE. This was disabled in version 1.11, but has been + reinstated (with a warning) in 1.11.2, as there are some cases + where this behavior can actually have some use. + + A combination with ‘-nc’ is only accepted if the given output file + does not exist. + + Note that a combination with ‘-k’ is only permitted when + downloading a single document, as in that case it will just convert + all relative URIs to external ones; ‘-k’ makes no sense for + multiple URIs when they’re all being downloaded to a single file; + ‘-k’ can be used only when the output is a regular file. + +‘-nc’ +‘--no-clobber’ + If a file is downloaded more than once in the same directory, + Wget’s behavior depends on a few options, including ‘-nc’. In + certain cases, the local file will be “clobbered”, or overwritten, + upon repeated download. In other cases it will be preserved. + + When running Wget without ‘-N’, ‘-nc’, ‘-r’, or ‘-p’, downloading + the same file in the same directory will result in the original + copy of FILE being preserved and the second copy being named + ‘FILE.1’. If that file is downloaded yet again, the third copy + will be named ‘FILE.2’, and so on. (This is also the behavior with + ‘-nd’, even if ‘-r’ or ‘-p’ are in effect.) When ‘-nc’ is + specified, this behavior is suppressed, and Wget will refuse to + download newer copies of ‘FILE’. Therefore, “‘no-clobber’” is + actually a misnomer in this mode—it’s not clobbering that’s + prevented (as the numeric suffixes were already preventing + clobbering), but rather the multiple version saving that’s + prevented. + + When running Wget with ‘-r’ or ‘-p’, but without ‘-N’, ‘-nd’, or + ‘-nc’, re-downloading a file will result in the new copy simply + overwriting the old. Adding ‘-nc’ will prevent this behavior, + instead causing the original version to be preserved and any newer + copies on the server to be ignored. + + When running Wget with ‘-N’, with or without ‘-r’ or ‘-p’, the + decision as to whether or not to download a newer copy of a file + depends on the local and remote timestamp and size of the file + (*note Time-Stamping::). ‘-nc’ may not be specified at the same + time as ‘-N’. + + A combination with ‘-O’/‘--output-document’ is only accepted if the + given output file does not exist. + + Note that when ‘-nc’ is specified, files with the suffixes ‘.html’ + or ‘.htm’ will be loaded from the local disk and parsed as if they + had been retrieved from the Web. + +‘--backups=BACKUPS’ + Before (over)writing a file, back up an existing file by adding a + ‘.1’ suffix (‘_1’ on VMS) to the file name. Such backup files are + rotated to ‘.2’, ‘.3’, and so on, up to BACKUPS (and lost beyond + that). + +‘--no-netrc’ + Do not try to obtain credentials from ‘.netrc’ file. By default + ‘.netrc’ file is searched for credentials in case none have been + passed on command line and authentication is required. + +‘-c’ +‘--continue’ + Continue getting a partially-downloaded file. This is useful when + you want to finish up a download started by a previous instance of + Wget, or by another program. For instance: + + wget -c ftp://sunsite.doc.ic.ac.uk/ls-lR.Z + + If there is a file named ‘ls-lR.Z’ in the current directory, Wget + will assume that it is the first portion of the remote file, and + will ask the server to continue the retrieval from an offset equal + to the length of the local file. + + Note that you don’t need to specify this option if you just want + the current invocation of Wget to retry downloading a file should + the connection be lost midway through. This is the default + behavior. ‘-c’ only affects resumption of downloads started + _prior_ to this invocation of Wget, and whose local files are still + sitting around. + + Without ‘-c’, the previous example would just download the remote + file to ‘ls-lR.Z.1’, leaving the truncated ‘ls-lR.Z’ file alone. + + If you use ‘-c’ on a non-empty file, and the server does not + support continued downloading, Wget will restart the download from + scratch and overwrite the existing file entirely. + + Beginning with Wget 1.7, if you use ‘-c’ on a file which is of + equal size as the one on the server, Wget will refuse to download + the file and print an explanatory message. The same happens when + the file is smaller on the server than locally (presumably because + it was changed on the server since your last download + attempt)—because “continuing” is not meaningful, no download + occurs. + + On the other side of the coin, while using ‘-c’, any file that’s + bigger on the server than locally will be considered an incomplete + download and only ‘(length(remote) - length(local))’ bytes will be + downloaded and tacked onto the end of the local file. This + behavior can be desirable in certain cases—for instance, you can + use ‘wget -c’ to download just the new portion that’s been appended + to a data collection or log file. + + However, if the file is bigger on the server because it’s been + _changed_, as opposed to just _appended_ to, you’ll end up with a + garbled file. Wget has no way of verifying that the local file is + really a valid prefix of the remote file. You need to be + especially careful of this when using ‘-c’ in conjunction with + ‘-r’, since every file will be considered as an "incomplete + download" candidate. + + Another instance where you’ll get a garbled file if you try to use + ‘-c’ is if you have a lame HTTP proxy that inserts a “transfer + interrupted” string into the local file. In the future a + “rollback” option may be added to deal with this case. + + Note that ‘-c’ only works with FTP servers and with HTTP servers + that support the ‘Range’ header. + +‘--start-pos=OFFSET’ + Start downloading at zero-based position OFFSET. Offset may be + expressed in bytes, kilobytes with the ‘k’ suffix, or megabytes + with the ‘m’ suffix, etc. + + ‘--start-pos’ has higher precedence over ‘--continue’. When + ‘--start-pos’ and ‘--continue’ are both specified, wget will emit a + warning then proceed as if ‘--continue’ was absent. + + Server support for continued download is required, otherwise + ‘--start-pos’ cannot help. See ‘-c’ for details. + +‘--progress=TYPE’ + Select the type of the progress indicator you wish to use. Legal + indicators are “dot” and “bar”. + + The “bar” indicator is used by default. It draws an ASCII progress + bar graphics (a.k.a “thermometer” display) indicating the status of + retrieval. If the output is not a TTY, the “dot” bar will be used + by default. + + Use ‘--progress=dot’ to switch to the “dot” display. It traces the + retrieval by printing dots on the screen, each dot representing a + fixed amount of downloaded data. + + The progress TYPE can also take one or more parameters. The + parameters vary based on the TYPE selected. Parameters to TYPE are + passed by appending them to the type sperated by a colon (:) like + this: ‘--progress=TYPE:PARAMETER1:PARAMETER2’. + + When using the dotted retrieval, you may set the “style” by + specifying the type as ‘dot:STYLE’. Different styles assign + different meaning to one dot. With the ‘default’ style each dot + represents 1K, there are ten dots in a cluster and 50 dots in a + line. The ‘binary’ style has a more “computer”-like orientation—8K + dots, 16-dots clusters and 48 dots per line (which makes for 384K + lines). The ‘mega’ style is suitable for downloading large + files—each dot represents 64K retrieved, there are eight dots in a + cluster, and 48 dots on each line (so each line contains 3M). If + ‘mega’ is not enough then you can use the ‘giga’ style—each dot + represents 1M retrieved, there are eight dots in a cluster, and 32 + dots on each line (so each line contains 32M). + + With ‘--progress=bar’, there are currently two possible parameters, + FORCE and NOSCROLL. + + When the output is not a TTY, the progress bar always falls back to + “dot”, even if ‘--progress=bar’ was passed to Wget during + invocation. This behaviour can be overridden and the “bar” output + forced by using the “force” parameter as ‘--progress=bar:force’. + + By default, the ‘bar’ style progress bar scroll the name of the + file from left to right for the file being downloaded if the + filename exceeds the maximum length allotted for its display. In + certain cases, such as with ‘--progress=bar:force’, one may not + want the scrolling filename in the progress bar. By passing the + “noscroll” parameter, Wget can be forced to display as much of the + filename as possible without scrolling through it. + + Note that you can set the default style using the ‘progress’ + command in ‘.wgetrc’. That setting may be overridden from the + command line. For example, to force the bar output without + scrolling, use ‘--progress=bar:force:noscroll’. + +‘--show-progress’ + Force wget to display the progress bar in any verbosity. + + By default, wget only displays the progress bar in verbose mode. + One may however, want wget to display the progress bar on screen in + conjunction with any other verbosity modes like ‘--no-verbose’ or + ‘--quiet’. This is often a desired a property when invoking wget + to download several small/large files. In such a case, wget could + simply be invoked with this parameter to get a much cleaner output + on the screen. + + This option will also force the progress bar to be printed to + ‘stderr’ when used alongside the ‘--output-file’ option. + +‘-N’ +‘--timestamping’ + Turn on time-stamping. *Note Time-Stamping::, for details. + +‘--no-if-modified-since’ + Do not send If-Modified-Since header in ‘-N’ mode. Send + preliminary HEAD request instead. This has only effect in ‘-N’ + mode. + +‘--no-use-server-timestamps’ + Don’t set the local file’s timestamp by the one on the server. + + By default, when a file is downloaded, its timestamps are set to + match those from the remote file. This allows the use of + ‘--timestamping’ on subsequent invocations of wget. However, it is + sometimes useful to base the local file’s timestamp on when it was + actually downloaded; for that purpose, the + ‘--no-use-server-timestamps’ option has been provided. + +‘-S’ +‘--server-response’ + Print the headers sent by HTTP servers and responses sent by FTP + servers. + +‘--spider’ + When invoked with this option, Wget will behave as a Web “spider”, + which means that it will not download the pages, just check that + they are there. For example, you can use Wget to check your + bookmarks: + + wget --spider --force-html -i bookmarks.html + + This feature needs much more work for Wget to get close to the + functionality of real web spiders. + +‘-T seconds’ +‘--timeout=SECONDS’ + Set the network timeout to SECONDS seconds. This is equivalent to + specifying ‘--dns-timeout’, ‘--connect-timeout’, and + ‘--read-timeout’, all at the same time. + + When interacting with the network, Wget can check for timeout and + abort the operation if it takes too long. This prevents anomalies + like hanging reads and infinite connects. The only timeout enabled + by default is a 900-second read timeout. Setting a timeout to 0 + disables it altogether. Unless you know what you are doing, it is + best not to change the default timeout settings. + + All timeout-related options accept decimal values, as well as + subsecond values. For example, ‘0.1’ seconds is a legal (though + unwise) choice of timeout. Subsecond timeouts are useful for + checking server response times or for testing network latency. + +‘--dns-timeout=SECONDS’ + Set the DNS lookup timeout to SECONDS seconds. DNS lookups that + don’t complete within the specified time will fail. By default, + there is no timeout on DNS lookups, other than that implemented by + system libraries. + +‘--connect-timeout=SECONDS’ + Set the connect timeout to SECONDS seconds. TCP connections that + take longer to establish will be aborted. By default, there is no + connect timeout, other than that implemented by system libraries. + +‘--read-timeout=SECONDS’ + Set the read (and write) timeout to SECONDS seconds. The “time” of + this timeout refers to “idle time”: if, at any point in the + download, no data is received for more than the specified number of + seconds, reading fails and the download is restarted. This option + does not directly affect the duration of the entire download. + + Of course, the remote server may choose to terminate the connection + sooner than this option requires. The default read timeout is 900 + seconds. + +‘--limit-rate=AMOUNT’ + Limit the download speed to AMOUNT bytes per second. Amount may be + expressed in bytes, kilobytes with the ‘k’ suffix, or megabytes + with the ‘m’ suffix. For example, ‘--limit-rate=20k’ will limit + the retrieval rate to 20KB/s. This is useful when, for whatever + reason, you don’t want Wget to consume the entire available + bandwidth. + + This option allows the use of decimal numbers, usually in + conjunction with power suffixes; for example, ‘--limit-rate=2.5k’ + is a legal value. + + Note that Wget implements the limiting by sleeping the appropriate + amount of time after a network read that took less time than + specified by the rate. Eventually this strategy causes the TCP + transfer to slow down to approximately the specified rate. + However, it may take some time for this balance to be achieved, so + don’t be surprised if limiting the rate doesn’t work well with very + small files. + +‘-w SECONDS’ +‘--wait=SECONDS’ + Wait the specified number of seconds between the retrievals. Use + of this option is recommended, as it lightens the server load by + making the requests less frequent. Instead of in seconds, the time + can be specified in minutes using the ‘m’ suffix, in hours using + ‘h’ suffix, or in days using ‘d’ suffix. + + Specifying a large value for this option is useful if the network + or the destination host is down, so that Wget can wait long enough + to reasonably expect the network error to be fixed before the + retry. The waiting interval specified by this function is + influenced by ‘--random-wait’, which see. + +‘--waitretry=SECONDS’ + If you don’t want Wget to wait between _every_ retrieval, but only + between retries of failed downloads, you can use this option. Wget + will use “linear backoff”, waiting 1 second after the first failure + on a given file, then waiting 2 seconds after the second failure on + that file, up to the maximum number of SECONDS you specify. + + By default, Wget will assume a value of 10 seconds. + +‘--random-wait’ + Some web sites may perform log analysis to identify retrieval + programs such as Wget by looking for statistically significant + similarities in the time between requests. This option causes the + time between requests to vary between 0.5 and 1.5 * WAIT seconds, + where WAIT was specified using the ‘--wait’ option, in order to + mask Wget’s presence from such analysis. + + A 2001 article in a publication devoted to development on a popular + consumer platform provided code to perform this analysis on the + fly. Its author suggested blocking at the class C address level to + ensure automated retrieval programs were blocked despite changing + DHCP-supplied addresses. + + The ‘--random-wait’ option was inspired by this ill-advised + recommendation to block many unrelated users from a web site due to + the actions of one. + +‘--no-proxy’ + Don’t use proxies, even if the appropriate ‘*_proxy’ environment + variable is defined. + + *Note Proxies::, for more information about the use of proxies with + Wget. + +‘-Q QUOTA’ +‘--quota=QUOTA’ + Specify download quota for automatic retrievals. The value can be + specified in bytes (default), kilobytes (with ‘k’ suffix), or + megabytes (with ‘m’ suffix). + + Note that quota will never affect downloading a single file. So if + you specify ‘wget -Q10k https://example.com/ls-lR.gz’, all of the + ‘ls-lR.gz’ will be downloaded. The same goes even when several + URLs are specified on the command-line. The quota is checked only + at the end of each downloaded file, so it will never result in a + partially downloaded file. Thus you may safely type ‘wget -Q2m -i + sites’—download will be aborted after the file that exhausts the + quota is completely downloaded. + + Setting quota to 0 or to ‘inf’ unlimits the download quota. + +‘--no-dns-cache’ + Turn off caching of DNS lookups. Normally, Wget remembers the IP + addresses it looked up from DNS so it doesn’t have to repeatedly + contact the DNS server for the same (typically small) set of hosts + it retrieves from. This cache exists in memory only; a new Wget + run will contact DNS again. + + However, it has been reported that in some situations it is not + desirable to cache host names, even for the duration of a + short-running application like Wget. With this option Wget issues + a new DNS lookup (more precisely, a new call to ‘gethostbyname’ or + ‘getaddrinfo’) each time it makes a new connection. Please note + that this option will _not_ affect caching that might be performed + by the resolving library or by an external caching layer, such as + NSCD. + + If you don’t understand exactly what this option does, you probably + won’t need it. + +‘--restrict-file-names=MODES’ + Change which characters found in remote URLs must be escaped during + generation of local filenames. Characters that are “restricted” by + this option are escaped, i.e. replaced with ‘%HH’, where ‘HH’ is + the hexadecimal number that corresponds to the restricted + character. This option may also be used to force all alphabetical + cases to be either lower- or uppercase. + + By default, Wget escapes the characters that are not valid or safe + as part of file names on your operating system, as well as control + characters that are typically unprintable. This option is useful + for changing these defaults, perhaps because you are downloading to + a non-native partition, or because you want to disable escaping of + the control characters, or you want to further restrict characters + to only those in the ASCII range of values. + + The MODES are a comma-separated set of text values. The acceptable + values are ‘unix’, ‘windows’, ‘nocontrol’, ‘ascii’, ‘lowercase’, + and ‘uppercase’. The values ‘unix’ and ‘windows’ are mutually + exclusive (one will override the other), as are ‘lowercase’ and + ‘uppercase’. Those last are special cases, as they do not change + the set of characters that would be escaped, but rather force local + file paths to be converted either to lower- or uppercase. + + When “unix” is specified, Wget escapes the character ‘/’ and the + control characters in the ranges 0–31 and 128–159. This is the + default on Unix-like operating systems. + + When “windows” is given, Wget escapes the characters ‘\’, ‘|’, ‘/’, + ‘:’, ‘?’, ‘"’, ‘*’, ‘<’, ‘>’, and the control characters in the + ranges 0–31 and 128–159. In addition to this, Wget in Windows mode + uses ‘+’ instead of ‘:’ to separate host and port in local file + names, and uses ‘@’ instead of ‘?’ to separate the query portion of + the file name from the rest. Therefore, a URL that would be saved + as ‘www.xemacs.org:4300/search.pl?input=blah’ in Unix mode would be + saved as ‘www.xemacs.org+4300/search.pl@input=blah’ in Windows + mode. This mode is the default on Windows. + + If you specify ‘nocontrol’, then the escaping of the control + characters is also switched off. This option may make sense when + you are downloading URLs whose names contain UTF-8 characters, on a + system which can save and display filenames in UTF-8 (some possible + byte values used in UTF-8 byte sequences fall in the range of + values designated by Wget as “controls”). + + The ‘ascii’ mode is used to specify that any bytes whose values are + outside the range of ASCII characters (that is, greater than 127) + shall be escaped. This can be useful when saving filenames whose + encoding does not match the one used locally. + +‘-4’ +‘--inet4-only’ +‘-6’ +‘--inet6-only’ + Force connecting to IPv4 or IPv6 addresses. With ‘--inet4-only’ or + ‘-4’, Wget will only connect to IPv4 hosts, ignoring AAAA records + in DNS, and refusing to connect to IPv6 addresses specified in + URLs. Conversely, with ‘--inet6-only’ or ‘-6’, Wget will only + connect to IPv6 hosts and ignore A records and IPv4 addresses. + + Neither options should be needed normally. By default, an + IPv6-aware Wget will use the address family specified by the host’s + DNS record. If the DNS responds with both IPv4 and IPv6 addresses, + Wget will try them in sequence until it finds one it can connect + to. (Also see ‘--prefer-family’ option described below.) + + These options can be used to deliberately force the use of IPv4 or + IPv6 address families on dual family systems, usually to aid + debugging or to deal with broken network configuration. Only one + of ‘--inet6-only’ and ‘--inet4-only’ may be specified at the same + time. Neither option is available in Wget compiled without IPv6 + support. + +‘--prefer-family=none/IPv4/IPv6’ + When given a choice of several addresses, connect to the addresses + with specified address family first. The address order returned by + DNS is used without change by default. + + This avoids spurious errors and connect attempts when accessing + hosts that resolve to both IPv6 and IPv4 addresses from IPv4 + networks. For example, ‘www.kame.net’ resolves to + ‘2001:200:0:8002:203:47ff:fea5:3085’ and to ‘203.178.141.194’. + When the preferred family is ‘IPv4’, the IPv4 address is used + first; when the preferred family is ‘IPv6’, the IPv6 address is + used first; if the specified value is ‘none’, the address order + returned by DNS is used without change. + + Unlike ‘-4’ and ‘-6’, this option doesn’t inhibit access to any + address family, it only changes the _order_ in which the addresses + are accessed. Also note that the reordering performed by this + option is “stable”—it doesn’t affect order of addresses of the same + family. That is, the relative order of all IPv4 addresses and of + all IPv6 addresses remains intact in all cases. + +‘--retry-connrefused’ + Consider “connection refused” a transient error and try again. + Normally Wget gives up on a URL when it is unable to connect to the + site because failure to connect is taken as a sign that the server + is not running at all and that retries would not help. This option + is for mirroring unreliable sites whose servers tend to disappear + for short periods of time. + +‘--user=USER’ +‘--password=PASSWORD’ + Specify the username USER and password PASSWORD for both FTP and + HTTP file retrieval. These parameters can be overridden using the + ‘--ftp-user’ and ‘--ftp-password’ options for FTP connections and + the ‘--http-user’ and ‘--http-password’ options for HTTP + connections. + +‘--ask-password’ + Prompt for a password for each connection established. Cannot be + specified when ‘--password’ is being used, because they are + mutually exclusive. + +‘--use-askpass=COMMAND’ + Prompt for a user and password using the specified command. If no + command is specified then the command in the environment variable + WGET_ASKPASS is used. If WGET_ASKPASS is not set then the command + in the environment variable SSH_ASKPASS is used. + + You can set the default command for use-askpass in the ‘.wgetrc’. + That setting may be overridden from the command line. + +‘--no-iri’ + + Turn off internationalized URI (IRI) support. Use ‘--iri’ to turn + it on. IRI support is activated by default. + + You can set the default state of IRI support using the ‘iri’ + command in ‘.wgetrc’. That setting may be overridden from the + command line. + +‘--local-encoding=ENCODING’ + + Force Wget to use ENCODING as the default system encoding. That + affects how Wget converts URLs specified as arguments from locale + to UTF-8 for IRI support. + + Wget use the function ‘nl_langinfo()’ and then the ‘CHARSET’ + environment variable to get the locale. If it fails, ASCII is + used. + + You can set the default local encoding using the ‘local_encoding’ + command in ‘.wgetrc’. That setting may be overridden from the + command line. + +‘--remote-encoding=ENCODING’ + + Force Wget to use ENCODING as the default remote server encoding. + That affects how Wget converts URIs found in files from remote + encoding to UTF-8 during a recursive fetch. This options is only + useful for IRI support, for the interpretation of non-ASCII + characters. + + For HTTP, remote encoding can be found in HTTP ‘Content-Type’ + header and in HTML ‘Content-Type http-equiv’ meta tag. + + You can set the default encoding using the ‘remoteencoding’ command + in ‘.wgetrc’. That setting may be overridden from the command + line. + +‘--unlink’ + + Force Wget to unlink file instead of clobbering existing file. + This option is useful for downloading to the directory with + hardlinks. + + +File: wget.info, Node: Directory Options, Next: HTTP Options, Prev: Download Options, Up: Invoking + +2.6 Directory Options +===================== + +‘-nd’ +‘--no-directories’ + Do not create a hierarchy of directories when retrieving + recursively. With this option turned on, all files will get saved + to the current directory, without clobbering (if a name shows up + more than once, the filenames will get extensions ‘.n’). + +‘-x’ +‘--force-directories’ + The opposite of ‘-nd’—create a hierarchy of directories, even if + one would not have been created otherwise. E.g. ‘wget -x + http://fly.srk.fer.hr/robots.txt’ will save the downloaded file to + ‘fly.srk.fer.hr/robots.txt’. + +‘-nH’ +‘--no-host-directories’ + Disable generation of host-prefixed directories. By default, + invoking Wget with ‘-r http://fly.srk.fer.hr/’ will create a + structure of directories beginning with ‘fly.srk.fer.hr/’. This + option disables such behavior. + +‘--protocol-directories’ + Use the protocol name as a directory component of local file names. + For example, with this option, ‘wget -r http://HOST’ will save to + ‘http/HOST/...’ rather than just to ‘HOST/...’. + +‘--cut-dirs=NUMBER’ + Ignore NUMBER directory components. This is useful for getting a + fine-grained control over the directory where recursive retrieval + will be saved. + + Take, for example, the directory at + ‘ftp://ftp.xemacs.org/pub/xemacs/’. If you retrieve it with ‘-r’, + it will be saved locally under ‘ftp.xemacs.org/pub/xemacs/’. While + the ‘-nH’ option can remove the ‘ftp.xemacs.org/’ part, you are + still stuck with ‘pub/xemacs’. This is where ‘--cut-dirs’ comes in + handy; it makes Wget not “see” NUMBER remote directory components. + Here are several examples of how ‘--cut-dirs’ option works. + + No options -> ftp.xemacs.org/pub/xemacs/ + -nH -> pub/xemacs/ + -nH --cut-dirs=1 -> xemacs/ + -nH --cut-dirs=2 -> . + + --cut-dirs=1 -> ftp.xemacs.org/xemacs/ + ... + + If you just want to get rid of the directory structure, this option + is similar to a combination of ‘-nd’ and ‘-P’. However, unlike + ‘-nd’, ‘--cut-dirs’ does not lose with subdirectories—for instance, + with ‘-nH --cut-dirs=1’, a ‘beta/’ subdirectory will be placed to + ‘xemacs/beta’, as one would expect. + +‘-P PREFIX’ +‘--directory-prefix=PREFIX’ + Set directory prefix to PREFIX. The “directory prefix” is the + directory where all other files and subdirectories will be saved + to, i.e. the top of the retrieval tree. The default is ‘.’ (the + current directory). + + +File: wget.info, Node: HTTP Options, Next: HTTPS (SSL/TLS) Options, Prev: Directory Options, Up: Invoking + +2.7 HTTP Options +================ + +‘--default-page=NAME’ + Use NAME as the default file name when it isn’t known (i.e., for + URLs that end in a slash), instead of ‘index.html’. + +‘-E’ +‘--adjust-extension’ + If a file of type ‘application/xhtml+xml’ or ‘text/html’ is + downloaded and the URL does not end with the regexp + ‘\.[Hh][Tt][Mm][Ll]?’, this option will cause the suffix ‘.html’ to + be appended to the local filename. This is useful, for instance, + when you’re mirroring a remote site that uses ‘.asp’ pages, but you + want the mirrored pages to be viewable on your stock Apache server. + Another good use for this is when you’re downloading CGI-generated + materials. A URL like ‘http://site.com/article.cgi?25’ will be + saved as ‘article.cgi?25.html’. + + Note that filenames changed in this way will be re-downloaded every + time you re-mirror a site, because Wget can’t tell that the local + ‘X.html’ file corresponds to remote URL ‘X’ (since it doesn’t yet + know that the URL produces output of type ‘text/html’ or + ‘application/xhtml+xml’. + + As of version 1.12, Wget will also ensure that any downloaded files + of type ‘text/css’ end in the suffix ‘.css’, and the option was + renamed from ‘--html-extension’, to better reflect its new + behavior. The old option name is still acceptable, but should now + be considered deprecated. + + As of version 1.19.2, Wget will also ensure that any downloaded + files with a ‘Content-Encoding’ of ‘br’, ‘compress’, ‘deflate’ or + ‘gzip’ end in the suffix ‘.br’, ‘.Z’, ‘.zlib’ and ‘.gz’ + respectively. + + At some point in the future, this option may well be expanded to + include suffixes for other types of content, including content + types that are not parsed by Wget. + +‘--http-user=USER’ +‘--http-password=PASSWORD’ + Specify the username USER and password PASSWORD on an HTTP server. + According to the type of the challenge, Wget will encode them using + either the ‘basic’ (insecure), the ‘digest’, or the Windows ‘NTLM’ + authentication scheme. + + Another way to specify username and password is in the URL itself + (*note URL Format::). Either method reveals your password to + anyone who bothers to run ‘ps’. To prevent the passwords from + being seen, use the ‘--use-askpass’ or store them in ‘.wgetrc’ or + ‘.netrc’, and make sure to protect those files from other users + with ‘chmod’. If the passwords are really important, do not leave + them lying in those files either—edit the files and delete them + after Wget has started the download. + +‘--no-http-keep-alive’ + Turn off the “keep-alive” feature for HTTP downloads. Normally, + Wget asks the server to keep the connection open so that, when you + download more than one document from the same server, they get + transferred over the same TCP connection. This saves time and at + the same time reduces the load on the server. + + This option is useful when, for some reason, persistent + (keep-alive) connections don’t work for you, for example due to a + server bug or due to the inability of server-side scripts to cope + with the connections. + +‘--no-cache’ + Disable server-side cache. In this case, Wget will send the remote + server appropriate directives (‘Cache-Control: no-cache’ and + ‘Pragma: no-cache’) to get the file from the remote service, rather + than returning the cached version. This is especially useful for + retrieving and flushing out-of-date documents on proxy servers. + + Caching is allowed by default. + +‘--no-cookies’ + Disable the use of cookies. Cookies are a mechanism for + maintaining server-side state. The server sends the client a + cookie using the ‘Set-Cookie’ header, and the client responds with + the same cookie upon further requests. Since cookies allow the + server owners to keep track of visitors and for sites to exchange + this information, some consider them a breach of privacy. The + default is to use cookies; however, _storing_ cookies is not on by + default. + +‘--load-cookies FILE’ + Load cookies from FILE before the first HTTP retrieval. FILE is a + textual file in the format originally used by Netscape’s + ‘cookies.txt’ file. + + You will typically use this option when mirroring sites that + require that you be logged in to access some or all of their + content. The login process typically works by the web server + issuing an HTTP cookie upon receiving and verifying your + credentials. The cookie is then resent by the browser when + accessing that part of the site, and so proves your identity. + + Mirroring such a site requires Wget to send the same cookies your + browser sends when communicating with the site. This is achieved + by ‘--load-cookies’—simply point Wget to the location of the + ‘cookies.txt’ file, and it will send the same cookies your browser + would send in the same situation. Different browsers keep textual + cookie files in different locations: + + Netscape 4.x. + The cookies are in ‘~/.netscape/cookies.txt’. + + Mozilla and Netscape 6.x. + Mozilla’s cookie file is also named ‘cookies.txt’, located + somewhere under ‘~/.mozilla’, in the directory of your + profile. The full path usually ends up looking somewhat like + ‘~/.mozilla/default/SOME-WEIRD-STRING/cookies.txt’. + + Internet Explorer. + You can produce a cookie file Wget can use by using the File + menu, Import and Export, Export Cookies. This has been tested + with Internet Explorer 5; it is not guaranteed to work with + earlier versions. + + Other browsers. + If you are using a different browser to create your cookies, + ‘--load-cookies’ will only work if you can locate or produce a + cookie file in the Netscape format that Wget expects. + + If you cannot use ‘--load-cookies’, there might still be an + alternative. If your browser supports a “cookie manager”, you can + use it to view the cookies used when accessing the site you’re + mirroring. Write down the name and value of the cookie, and + manually instruct Wget to send those cookies, bypassing the + “official” cookie support: + + wget --no-cookies --header "Cookie: NAME=VALUE" + +‘--save-cookies FILE’ + Save cookies to FILE before exiting. This will not save cookies + that have expired or that have no expiry time (so-called “session + cookies”), but also see ‘--keep-session-cookies’. + +‘--keep-session-cookies’ + When specified, causes ‘--save-cookies’ to also save session + cookies. Session cookies are normally not saved because they are + meant to be kept in memory and forgotten when you exit the browser. + Saving them is useful on sites that require you to log in or to + visit the home page before you can access some pages. With this + option, multiple Wget runs are considered a single browser session + as far as the site is concerned. + + Since the cookie file format does not normally carry session + cookies, Wget marks them with an expiry timestamp of 0. Wget’s + ‘--load-cookies’ recognizes those as session cookies, but it might + confuse other browsers. Also note that cookies so loaded will be + treated as other session cookies, which means that if you want + ‘--save-cookies’ to preserve them again, you must use + ‘--keep-session-cookies’ again. + +‘--ignore-length’ + Unfortunately, some HTTP servers (CGI programs, to be more precise) + send out bogus ‘Content-Length’ headers, which makes Wget go wild, + as it thinks not all the document was retrieved. You can spot this + syndrome if Wget retries getting the same document again and again, + each time claiming that the (otherwise normal) connection has + closed on the very same byte. + + With this option, Wget will ignore the ‘Content-Length’ header—as + if it never existed. + +‘--header=HEADER-LINE’ + Send HEADER-LINE along with the rest of the headers in each HTTP + request. The supplied header is sent as-is, which means it must + contain name and value separated by colon, and must not contain + newlines. + + You may define more than one additional header by specifying + ‘--header’ more than once. + + wget --header='Accept-Charset: iso-8859-2' \ + --header='Accept-Language: hr' \ + http://fly.srk.fer.hr/ + + Specification of an empty string as the header value will clear all + previous user-defined headers. + + As of Wget 1.10, this option can be used to override headers + otherwise generated automatically. This example instructs Wget to + connect to localhost, but to specify ‘foo.bar’ in the ‘Host’ + header: + + wget --header="Host: foo.bar" http://localhost/ + + In versions of Wget prior to 1.10 such use of ‘--header’ caused + sending of duplicate headers. + +‘--compression=TYPE’ + Choose the type of compression to be used. Legal values are + ‘auto’, ‘gzip’ and ‘none’. + + If ‘auto’ or ‘gzip’ are specified, Wget asks the server to compress + the file using the gzip compression format. If the server + compresses the file and responds with the ‘Content-Encoding’ header + field set appropriately, the file will be decompressed + automatically. + + If ‘none’ is specified, wget will not ask the server to compress + the file and will not decompress any server responses. This is the + default. + + Compression support is currently experimental. In case it is + turned on, please report any bugs to ‘bug-wget@gnu.org’. + +‘--max-redirect=NUMBER’ + Specifies the maximum number of redirections to follow for a + resource. The default is 20, which is usually far more than + necessary. However, on those occasions where you want to allow + more (or fewer), this is the option to use. + +‘--proxy-user=USER’ +‘--proxy-password=PASSWORD’ + Specify the username USER and password PASSWORD for authentication + on a proxy server. Wget will encode them using the ‘basic’ + authentication scheme. + + Security considerations similar to those with ‘--http-password’ + pertain here as well. + +‘--referer=URL’ + Include ‘Referer: URL’ header in HTTP request. Useful for + retrieving documents with server-side processing that assume they + are always being retrieved by interactive web browsers and only + come out properly when Referer is set to one of the pages that + point to them. + +‘--save-headers’ + Save the headers sent by the HTTP server to the file, preceding the + actual contents, with an empty line as the separator. + +‘-U AGENT-STRING’ +‘--user-agent=AGENT-STRING’ + Identify as AGENT-STRING to the HTTP server. + + The HTTP protocol allows the clients to identify themselves using a + ‘User-Agent’ header field. This enables distinguishing the WWW + software, usually for statistical purposes or for tracing of + protocol violations. Wget normally identifies as ‘Wget/VERSION’, + VERSION being the current version number of Wget. + + However, some sites have been known to impose the policy of + tailoring the output according to the ‘User-Agent’-supplied + information. While this is not such a bad idea in theory, it has + been abused by servers denying information to clients other than + (historically) Netscape or, more frequently, Microsoft Internet + Explorer. This option allows you to change the ‘User-Agent’ line + issued by Wget. Use of this option is discouraged, unless you + really know what you are doing. + + Specifying empty user agent with ‘--user-agent=""’ instructs Wget + not to send the ‘User-Agent’ header in HTTP requests. + +‘--post-data=STRING’ +‘--post-file=FILE’ + Use POST as the method for all HTTP requests and send the specified + data in the request body. ‘--post-data’ sends STRING as data, + whereas ‘--post-file’ sends the contents of FILE. Other than that, + they work in exactly the same way. In particular, they _both_ + expect content of the form ‘key1=value1&key2=value2’, with + percent-encoding for special characters; the only difference is + that one expects its content as a command-line parameter and the + other accepts its content from a file. In particular, + ‘--post-file’ is _not_ for transmitting files as form attachments: + those must appear as ‘key=value’ data (with appropriate + percent-coding) just like everything else. Wget does not currently + support ‘multipart/form-data’ for transmitting POST data; only + ‘application/x-www-form-urlencoded’. Only one of ‘--post-data’ and + ‘--post-file’ should be specified. + + Please note that wget does not require the content to be of the + form ‘key1=value1&key2=value2’, and neither does it test for it. + Wget will simply transmit whatever data is provided to it. Most + servers however expect the POST data to be in the above format when + processing HTML Forms. + + When sending a POST request using the ‘--post-file’ option, Wget + treats the file as a binary file and will send every character in + the POST request without stripping trailing newline or formfeed + characters. Any other control characters in the text will also be + sent as-is in the POST request. + + Please be aware that Wget needs to know the size of the POST data + in advance. Therefore the argument to ‘--post-file’ must be a + regular file; specifying a FIFO or something like ‘/dev/stdin’ + won’t work. It’s not quite clear how to work around this + limitation inherent in HTTP/1.0. Although HTTP/1.1 introduces + “chunked” transfer that doesn’t require knowing the request length + in advance, a client can’t use chunked unless it knows it’s talking + to an HTTP/1.1 server. And it can’t know that until it receives a + response, which in turn requires the request to have been completed + – a chicken-and-egg problem. + + Note: As of version 1.15 if Wget is redirected after the POST + request is completed, its behaviour will depend on the response + code returned by the server. In case of a 301 Moved Permanently, + 302 Moved Temporarily or 307 Temporary Redirect, Wget will, in + accordance with RFC2616, continue to send a POST request. In case + a server wants the client to change the Request method upon + redirection, it should send a 303 See Other response code. + + This example shows how to log in to a server using POST and then + proceed to download the desired pages, presumably only accessible + to authorized users: + + # Log in to the server. This can be done only once. + wget --save-cookies cookies.txt \ + --post-data 'user=foo&password=bar' \ + http://example.com/auth.php + + # Now grab the page or pages we care about. + wget --load-cookies cookies.txt \ + -p http://example.com/interesting/article.php + + If the server is using session cookies to track user + authentication, the above will not work because ‘--save-cookies’ + will not save them (and neither will browsers) and the + ‘cookies.txt’ file will be empty. In that case use + ‘--keep-session-cookies’ along with ‘--save-cookies’ to force + saving of session cookies. + +‘--method=HTTP-METHOD’ + For the purpose of RESTful scripting, Wget allows sending of other + HTTP Methods without the need to explicitly set them using + ‘--header=Header-Line’. Wget will use whatever string is passed to + it after ‘--method’ as the HTTP Method to the server. + +‘--body-data=DATA-STRING’ +‘--body-file=DATA-FILE’ + Must be set when additional data needs to be sent to the server + along with the Method specified using ‘--method’. ‘--body-data’ + sends STRING as data, whereas ‘--body-file’ sends the contents of + FILE. Other than that, they work in exactly the same way. + + Currently, ‘--body-file’ is _not_ for transmitting files as a + whole. Wget does not currently support ‘multipart/form-data’ for + transmitting data; only ‘application/x-www-form-urlencoded’. In + the future, this may be changed so that wget sends the + ‘--body-file’ as a complete file instead of sending its contents to + the server. Please be aware that Wget needs to know the contents + of BODY Data in advance, and hence the argument to ‘--body-file’ + should be a regular file. See ‘--post-file’ for a more detailed + explanation. Only one of ‘--body-data’ and ‘--body-file’ should be + specified. + + If Wget is redirected after the request is completed, Wget will + suspend the current method and send a GET request till the + redirection is completed. This is true for all redirection + response codes except 307 Temporary Redirect which is used to + explicitly specify that the request method should _not_ change. + Another exception is when the method is set to ‘POST’, in which + case the redirection rules specified under ‘--post-data’ are + followed. + +‘--content-disposition’ + + If this is set to on, experimental (not fully-functional) support + for ‘Content-Disposition’ headers is enabled. This can currently + result in extra round-trips to the server for a ‘HEAD’ request, and + is known to suffer from a few bugs, which is why it is not + currently enabled by default. + + This option is useful for some file-downloading CGI programs that + use ‘Content-Disposition’ headers to describe what the name of a + downloaded file should be. + + When combined with ‘--metalink-over-http’ and + ‘--trust-server-names’, a ‘Content-Type: application/metalink4+xml’ + file is named using the ‘Content-Disposition’ filename field, if + available. + +‘--content-on-error’ + + If this is set to on, wget will not skip the content when the + server responds with a http status code that indicates error. + +‘--trust-server-names’ + + If this is set, on a redirect, the local file name will be based on + the redirection URL. By default the local file name is based on the + original URL. When doing recursive retrieving this can be helpful + because in many web sites redirected URLs correspond to an + underlying file structure, while link URLs do not. + +‘--auth-no-challenge’ + + If this option is given, Wget will send Basic HTTP authentication + information (plaintext username and password) for all requests, + just like Wget 1.10.2 and prior did by default. + + Use of this option is not recommended, and is intended only to + support some few obscure servers, which never send HTTP + authentication challenges, but accept unsolicited auth info, say, + in addition to form-based authentication. + +‘--retry-on-host-error’ + Consider host errors, such as “Temporary failure in name + resolution”, as non-fatal, transient errors. + +‘--retry-on-http-error=CODE[,CODE,...]’ + Consider given HTTP response codes as non-fatal, transient errors. + Supply a comma-separated list of 3-digit HTTP response codes as + argument. Useful to work around special circumstances where + retries are required, but the server responds with an error code + normally not retried by Wget. Such errors might be 503 (Service + Unavailable) and 429 (Too Many Requests). Retries enabled by this + option are performed subject to the normal retry timing and retry + count limitations of Wget. + + Using this option is intended to support special use cases only and + is generally not recommended, as it can force retries even in cases + where the server is actually trying to decrease its load. Please + use wisely and only if you know what you are doing. + + +File: wget.info, Node: HTTPS (SSL/TLS) Options, Next: FTP Options, Prev: HTTP Options, Up: Invoking + +2.8 HTTPS (SSL/TLS) Options +=========================== + +To support encrypted HTTP (HTTPS) downloads, Wget must be compiled with +an external SSL library. The current default is GnuTLS. In addition, +Wget also supports HSTS (HTTP Strict Transport Security). If Wget is +compiled without SSL support, none of these options are available. + +‘--secure-protocol=PROTOCOL’ + Choose the secure protocol to be used. Legal values are ‘auto’, + ‘SSLv2’, ‘SSLv3’, ‘TLSv1’, ‘TLSv1_1’, ‘TLSv1_2’, ‘TLSv1_3’ and + ‘PFS’. If ‘auto’ is used, the SSL library is given the liberty of + choosing the appropriate protocol automatically, which is achieved + by sending a TLSv1 greeting. This is the default. + + Specifying ‘SSLv2’, ‘SSLv3’, ‘TLSv1’, ‘TLSv1_1’, ‘TLSv1_2’ or + ‘TLSv1_3’ forces the use of the corresponding protocol. This is + useful when talking to old and buggy SSL server implementations + that make it hard for the underlying SSL library to choose the + correct protocol version. Fortunately, such servers are quite + rare. + + Specifying ‘PFS’ enforces the use of the so-called Perfect Forward + Security cipher suites. In short, PFS adds security by creating a + one-time key for each SSL connection. It has a bit more CPU impact + on client and server. We use known to be secure ciphers (e.g. no + MD4) and the TLS protocol. This mode also explicitly excludes + non-PFS key exchange methods, such as RSA. + +‘--https-only’ + When in recursive mode, only HTTPS links are followed. + +‘--ciphers’ + Set the cipher list string. Typically this string sets the cipher + suites and other SSL/TLS options that the user wish should be used, + in a set order of preference (GnuTLS calls it ’priority string’). + This string will be fed verbatim to the SSL/TLS engine (OpenSSL or + GnuTLS) and hence its format and syntax is dependent on that. Wget + will not process or manipulate it in any way. Refer to the OpenSSL + or GnuTLS documentation for more information. + +‘--no-check-certificate’ + Don’t check the server certificate against the available + certificate authorities. Also don’t require the URL host name to + match the common name presented by the certificate. + + As of Wget 1.10, the default is to verify the server’s certificate + against the recognized certificate authorities, breaking the SSL + handshake and aborting the download if the verification fails. + Although this provides more secure downloads, it does break + interoperability with some sites that worked with previous Wget + versions, particularly those using self-signed, expired, or + otherwise invalid certificates. This option forces an “insecure” + mode of operation that turns the certificate verification errors + into warnings and allows you to proceed. + + If you encounter “certificate verification” errors or ones saying + that “common name doesn’t match requested host name”, you can use + this option to bypass the verification and proceed with the + download. _Only use this option if you are otherwise convinced of + the site’s authenticity, or if you really don’t care about the + validity of its certificate._ It is almost always a bad idea not + to check the certificates when transmitting confidential or + important data. For self-signed/internal certificates, you should + download the certificate and verify against that instead of forcing + this insecure mode. If you are really sure of not desiring any + certificate verification, you can specify –check-certificate=quiet + to tell wget to not print any warning about invalid certificates, + albeit in most cases this is the wrong thing to do. + +‘--certificate=FILE’ + Use the client certificate stored in FILE. This is needed for + servers that are configured to require certificates from the + clients that connect to them. Normally a certificate is not + required and this switch is optional. + +‘--certificate-type=TYPE’ + Specify the type of the client certificate. Legal values are ‘PEM’ + (assumed by default) and ‘DER’, also known as ‘ASN1’. + +‘--private-key=FILE’ + Read the private key from FILE. This allows you to provide the + private key in a file separate from the certificate. + +‘--private-key-type=TYPE’ + Specify the type of the private key. Accepted values are ‘PEM’ + (the default) and ‘DER’. + +‘--ca-certificate=FILE’ + Use FILE as the file with the bundle of certificate authorities + (“CA”) to verify the peers. The certificates must be in PEM + format. + + Without this option Wget looks for CA certificates at the + system-specified locations, chosen at OpenSSL installation time. + +‘--ca-directory=DIRECTORY’ + Specifies directory containing CA certificates in PEM format. Each + file contains one CA certificate, and the file name is based on a + hash value derived from the certificate. This is achieved by + processing a certificate directory with the ‘c_rehash’ utility + supplied with OpenSSL. Using ‘--ca-directory’ is more efficient + than ‘--ca-certificate’ when many certificates are installed + because it allows Wget to fetch certificates on demand. + + Without this option Wget looks for CA certificates at the + system-specified locations, chosen at OpenSSL installation time. + +‘--crl-file=FILE’ + Specifies a CRL file in FILE. This is needed for certificates that + have been revocated by the CAs. + +‘--pinnedpubkey=file/hashes’ + Tells wget to use the specified public key file (or hashes) to + verify the peer. This can be a path to a file which contains a + single public key in PEM or DER format, or any number of base64 + encoded sha256 hashes preceded by “sha256//” and separated by “;” + + When negotiating a TLS or SSL connection, the server sends a + certificate indicating its identity. A public key is extracted + from this certificate and if it does not exactly match the public + key(s) provided to this option, wget will abort the connection + before sending or receiving any data. + +‘--random-file=FILE’ + [OpenSSL and LibreSSL only] Use FILE as the source of random data + for seeding the pseudo-random number generator on systems without + ‘/dev/urandom’. + + On such systems the SSL library needs an external source of + randomness to initialize. Randomness may be provided by EGD (see + ‘--egd-file’ below) or read from an external source specified by + the user. If this option is not specified, Wget looks for random + data in ‘$RANDFILE’ or, if that is unset, in ‘$HOME/.rnd’. + + If you’re getting the “Could not seed OpenSSL PRNG; disabling SSL.” + error, you should provide random data using some of the methods + described above. + +‘--egd-file=FILE’ + [OpenSSL only] Use FILE as the EGD socket. EGD stands for “Entropy + Gathering Daemon”, a user-space program that collects data from + various unpredictable system sources and makes it available to + other programs that might need it. Encryption software, such as + the SSL library, needs sources of non-repeating randomness to seed + the random number generator used to produce cryptographically + strong keys. + + OpenSSL allows the user to specify his own source of entropy using + the ‘RAND_FILE’ environment variable. If this variable is unset, + or if the specified file does not produce enough randomness, + OpenSSL will read random data from EGD socket specified using this + option. + + If this option is not specified (and the equivalent startup command + is not used), EGD is never contacted. EGD is not needed on modern + Unix systems that support ‘/dev/urandom’. + +‘--no-hsts’ + Wget supports HSTS (HTTP Strict Transport Security, RFC 6797) by + default. Use ‘--no-hsts’ to make Wget act as a non-HSTS-compliant + UA. As a consequence, Wget would ignore all the + ‘Strict-Transport-Security’ headers, and would not enforce any + existing HSTS policy. + +‘--hsts-file=FILE’ + By default, Wget stores its HSTS database in ‘~/.wget-hsts’. You + can use ‘--hsts-file’ to override this. Wget will use the supplied + file as the HSTS database. Such file must conform to the correct + HSTS database format used by Wget. If Wget cannot parse the + provided file, the behaviour is unspecified. + + The Wget’s HSTS database is a plain text file. Each line contains + an HSTS entry (ie. a site that has issued a + ‘Strict-Transport-Security’ header and that therefore has specified + a concrete HSTS policy to be applied). Lines starting with a dash + (‘#’) are ignored by Wget. Please note that in spite of this + convenient human-readability hand-hacking the HSTS database is + generally not a good idea. + + An HSTS entry line consists of several fields separated by one or + more whitespace: + + ‘<hostname> SP [<port>] SP <include subdomains> SP <created> SP + <max-age>’ + + The HOSTNAME and PORT fields indicate the hostname and port to + which the given HSTS policy applies. The PORT field may be zero, + and it will, in most of the cases. That means that the port number + will not be taken into account when deciding whether such HSTS + policy should be applied on a given request (only the hostname will + be evaluated). When PORT is different to zero, both the target + hostname and the port will be evaluated and the HSTS policy will + only be applied if both of them match. This feature has been + included for testing/development purposes only. The Wget testsuite + (in ‘testenv/’) creates HSTS databases with explicit ports with the + purpose of ensuring Wget’s correct behaviour. Applying HSTS + policies to ports other than the default ones is discouraged by RFC + 6797 (see Appendix B "Differences between HSTS Policy and + Same-Origin Policy"). Thus, this functionality should not be used + in production environments and PORT will typically be zero. The + last three fields do what they are expected to. The field + INCLUDE_SUBDOMAINS can either be ‘1’ or ‘0’ and it signals whether + the subdomains of the target domain should be part of the given + HSTS policy as well. The CREATED and MAX-AGE fields hold the + timestamp values of when such entry was created (first seen by + Wget) and the HSTS-defined value ’max-age’, which states how long + should that HSTS policy remain active, measured in seconds elapsed + since the timestamp stored in CREATED. Once that time has passed, + that HSTS policy will no longer be valid and will eventually be + removed from the database. + + If you supply your own HSTS database via ‘--hsts-file’, be aware + that Wget may modify the provided file if any change occurs between + the HSTS policies requested by the remote servers and those in the + file. When Wget exits, it effectively updates the HSTS database by + rewriting the database file with the new entries. + + If the supplied file does not exist, Wget will create one. This + file will contain the new HSTS entries. If no HSTS entries were + generated (no ‘Strict-Transport-Security’ headers were sent by any + of the servers) then no file will be created, not even an empty + one. This behaviour applies to the default database file + (‘~/.wget-hsts’) as well: it will not be created until some server + enforces an HSTS policy. + + Care is taken not to override possible changes made by other Wget + processes at the same time over the HSTS database. Before dumping + the updated HSTS entries on the file, Wget will re-read it and + merge the changes. + + Using a custom HSTS database and/or modifying an existing one is + discouraged. For more information about the potential security + threats arose from such practice, see section 14 "Security + Considerations" of RFC 6797, specially section 14.9 "Creative + Manipulation of HSTS Policy Store". + +‘--warc-file=FILE’ + Use FILE as the destination WARC file. + +‘--warc-header=STRING’ + Use STRING into as the warcinfo record. + +‘--warc-max-size=SIZE’ + Set the maximum size of the WARC files to SIZE. + +‘--warc-cdx’ + Write CDX index files. + +‘--warc-dedup=FILE’ + Do not store records listed in this CDX file. + +‘--no-warc-compression’ + Do not compress WARC files with GZIP. + +‘--no-warc-digests’ + Do not calculate SHA1 digests. + +‘--no-warc-keep-log’ + Do not store the log file in a WARC record. + +‘--warc-tempdir=DIR’ + Specify the location for temporary files created by the WARC + writer. + + +File: wget.info, Node: FTP Options, Next: Recursive Retrieval Options, Prev: HTTPS (SSL/TLS) Options, Up: Invoking + +2.9 FTP Options +=============== + +‘--ftp-user=USER’ +‘--ftp-password=PASSWORD’ + Specify the username USER and password PASSWORD on an FTP server. + Without this, or the corresponding startup option, the password + defaults to ‘-wget@’, normally used for anonymous FTP. + + Another way to specify username and password is in the URL itself + (*note URL Format::). Either method reveals your password to + anyone who bothers to run ‘ps’. To prevent the passwords from + being seen, store them in ‘.wgetrc’ or ‘.netrc’, and make sure to + protect those files from other users with ‘chmod’. If the + passwords are really important, do not leave them lying in those + files either—edit the files and delete them after Wget has started + the download. + +‘--no-remove-listing’ + Don’t remove the temporary ‘.listing’ files generated by FTP + retrievals. Normally, these files contain the raw directory + listings received from FTP servers. Not removing them can be + useful for debugging purposes, or when you want to be able to + easily check on the contents of remote server directories (e.g. to + verify that a mirror you’re running is complete). + + Note that even though Wget writes to a known filename for this + file, this is not a security hole in the scenario of a user making + ‘.listing’ a symbolic link to ‘/etc/passwd’ or something and asking + ‘root’ to run Wget in his or her directory. Depending on the + options used, either Wget will refuse to write to ‘.listing’, + making the globbing/recursion/time-stamping operation fail, or the + symbolic link will be deleted and replaced with the actual + ‘.listing’ file, or the listing will be written to a + ‘.listing.NUMBER’ file. + + Even though this situation isn’t a problem, though, ‘root’ should + never run Wget in a non-trusted user’s directory. A user could do + something as simple as linking ‘index.html’ to ‘/etc/passwd’ and + asking ‘root’ to run Wget with ‘-N’ or ‘-r’ so the file will be + overwritten. + +‘--no-glob’ + Turn off FTP globbing. Globbing refers to the use of shell-like + special characters (“wildcards”), like ‘*’, ‘?’, ‘[’ and ‘]’ to + retrieve more than one file from the same directory at once, like: + + wget ftp://gnjilux.srk.fer.hr/*.msg + + By default, globbing will be turned on if the URL contains a + globbing character. This option may be used to turn globbing on or + off permanently. + + You may have to quote the URL to protect it from being expanded by + your shell. Globbing makes Wget look for a directory listing, + which is system-specific. This is why it currently works only with + Unix FTP servers (and the ones emulating Unix ‘ls’ output). + +‘--no-passive-ftp’ + Disable the use of the “passive” FTP transfer mode. Passive FTP + mandates that the client connect to the server to establish the + data connection rather than the other way around. + + If the machine is connected to the Internet directly, both passive + and active FTP should work equally well. Behind most firewall and + NAT configurations passive FTP has a better chance of working. + However, in some rare firewall configurations, active FTP actually + works when passive FTP doesn’t. If you suspect this to be the + case, use this option, or set ‘passive_ftp=off’ in your init file. + +‘--preserve-permissions’ + Preserve remote file permissions instead of permissions set by + umask. + +‘--retr-symlinks’ + By default, when retrieving FTP directories recursively and a + symbolic link is encountered, the symbolic link is traversed and + the pointed-to files are retrieved. Currently, Wget does not + traverse symbolic links to directories to download them + recursively, though this feature may be added in the future. + + When ‘--retr-symlinks=no’ is specified, the linked-to file is not + downloaded. Instead, a matching symbolic link is created on the + local file system. The pointed-to file will not be retrieved + unless this recursive retrieval would have encountered it + separately and downloaded it anyway. This option poses a security + risk where a malicious FTP Server may cause Wget to write to files + outside of the intended directories through a specially crafted + .LISTING file. + + Note that when retrieving a file (not a directory) because it was + specified on the command-line, rather than because it was recursed + to, this option has no effect. Symbolic links are always traversed + in this case. + +2.10 FTPS Options +================= + +‘--ftps-implicit’ + This option tells Wget to use FTPS implicitly. Implicit FTPS + consists of initializing SSL/TLS from the very beginning of the + control connection. This option does not send an ‘AUTH TLS’ + command: it assumes the server speaks FTPS and directly starts an + SSL/TLS connection. If the attempt is successful, the session + continues just like regular FTPS (‘PBSZ’ and ‘PROT’ are sent, + etc.). Implicit FTPS is no longer a requirement for FTPS + implementations, and thus many servers may not support it. If + ‘--ftps-implicit’ is passed and no explicit port number specified, + the default port for implicit FTPS, 990, will be used, instead of + the default port for the "normal" (explicit) FTPS which is the same + as that of FTP, 21. + +‘--no-ftps-resume-ssl’ + Do not resume the SSL/TLS session in the data channel. When + starting a data connection, Wget tries to resume the SSL/TLS + session previously started in the control connection. SSL/TLS + session resumption avoids performing an entirely new handshake by + reusing the SSL/TLS parameters of a previous session. Typically, + the FTPS servers want it that way, so Wget does this by default. + Under rare circumstances however, one might want to start an + entirely new SSL/TLS session in every data connection. This is + what ‘--no-ftps-resume-ssl’ is for. + +‘--ftps-clear-data-connection’ + All the data connections will be in plain text. Only the control + connection will be under SSL/TLS. Wget will send a ‘PROT C’ command + to achieve this, which must be approved by the server. + +‘--ftps-fallback-to-ftp’ + Fall back to FTP if FTPS is not supported by the target server. + For security reasons, this option is not asserted by default. The + default behaviour is to exit with an error. If a server does not + successfully reply to the initial ‘AUTH TLS’ command, or in the + case of implicit FTPS, if the initial SSL/TLS connection attempt is + rejected, it is considered that such server does not support FTPS. + + +File: wget.info, Node: Recursive Retrieval Options, Next: Recursive Accept/Reject Options, Prev: FTP Options, Up: Invoking + +2.11 Recursive Retrieval Options +================================ + +‘-r’ +‘--recursive’ + Turn on recursive retrieving. *Note Recursive Download::, for more + details. The default maximum depth is 5. + +‘-l DEPTH’ +‘--level=DEPTH’ + Set the maximum number of subdirectories that Wget will recurse + into to DEPTH. In order to prevent one from accidentally + downloading very large websites when using recursion this is + limited to a depth of 5 by default, i.e., it will traverse at most + 5 directories deep starting from the provided URL. Set ‘-l 0’ or + ‘-l inf’ for infinite recursion depth. + + wget -r -l 0 http://SITE/1.html + + Ideally, one would expect this to download just ‘1.html’. but + unfortunately this is not the case, because ‘-l 0’ is equivalent to + ‘-l inf’—that is, infinite recursion. To download a single HTML + page (or a handful of them), specify them all on the command line + and leave away ‘-r’ and ‘-l’. To download the essential items to + view a single HTML page, see ‘page requisites’. + +‘--delete-after’ + This option tells Wget to delete every single file it downloads, + _after_ having done so. It is useful for pre-fetching popular + pages through a proxy, e.g.: + + wget -r -nd --delete-after http://whatever.com/~popular/page/ + + The ‘-r’ option is to retrieve recursively, and ‘-nd’ to not create + directories. + + Note that ‘--delete-after’ deletes files on the local machine. It + does not issue the ‘DELE’ command to remote FTP sites, for + instance. Also note that when ‘--delete-after’ is specified, + ‘--convert-links’ is ignored, so ‘.orig’ files are simply not + created in the first place. + +‘-k’ +‘--convert-links’ + After the download is complete, convert the links in the document + to make them suitable for local viewing. This affects not only the + visible hyperlinks, but any part of the document that links to + external content, such as embedded images, links to style sheets, + hyperlinks to non-HTML content, etc. + + Each link will be changed in one of the two ways: + + • The links to files that have been downloaded by Wget will be + changed to refer to the file they point to as a relative link. + + Example: if the downloaded file ‘/foo/doc.html’ links to + ‘/bar/img.gif’, also downloaded, then the link in ‘doc.html’ + will be modified to point to ‘../bar/img.gif’. This kind of + transformation works reliably for arbitrary combinations of + directories. + + • The links to files that have not been downloaded by Wget will + be changed to include host name and absolute path of the + location they point to. + + Example: if the downloaded file ‘/foo/doc.html’ links to + ‘/bar/img.gif’ (or to ‘../bar/img.gif’), then the link in + ‘doc.html’ will be modified to point to + ‘http://HOSTNAME/bar/img.gif’. + + Because of this, local browsing works reliably: if a linked file + was downloaded, the link will refer to its local name; if it was + not downloaded, the link will refer to its full Internet address + rather than presenting a broken link. The fact that the former + links are converted to relative links ensures that you can move the + downloaded hierarchy to another directory. + + Note that only at the end of the download can Wget know which links + have been downloaded. Because of that, the work done by ‘-k’ will + be performed at the end of all the downloads. + +‘--convert-file-only’ + This option converts only the filename part of the URLs, leaving + the rest of the URLs untouched. This filename part is sometimes + referred to as the "basename", although we avoid that term here in + order not to cause confusion. + + It works particularly well in conjunction with + ‘--adjust-extension’, although this coupling is not enforced. It + proves useful to populate Internet caches with files downloaded + from different hosts. + + Example: if some link points to ‘//foo.com/bar.cgi?xyz’ with + ‘--adjust-extension’ asserted and its local destination is intended + to be ‘./foo.com/bar.cgi?xyz.css’, then the link would be converted + to ‘//foo.com/bar.cgi?xyz.css’. Note that only the filename part + has been modified. The rest of the URL has been left untouched, + including the net path (‘//’) which would otherwise be processed by + Wget and converted to the effective scheme (ie. ‘http://’). + +‘-K’ +‘--backup-converted’ + When converting a file, back up the original version with a ‘.orig’ + suffix. Affects the behavior of ‘-N’ (*note HTTP Time-Stamping + Internals::). + +‘-m’ +‘--mirror’ + Turn on options suitable for mirroring. This option turns on + recursion and time-stamping, sets infinite recursion depth and + keeps FTP directory listings. It is currently equivalent to ‘-r -N + -l inf --no-remove-listing’. + +‘-p’ +‘--page-requisites’ + This option causes Wget to download all the files that are + necessary to properly display a given HTML page. This includes + such things as inlined images, sounds, and referenced stylesheets. + + Ordinarily, when downloading a single HTML page, any requisite + documents that may be needed to display it properly are not + downloaded. Using ‘-r’ together with ‘-l’ can help, but since Wget + does not ordinarily distinguish between external and inlined + documents, one is generally left with “leaf documents” that are + missing their requisites. + + For instance, say document ‘1.html’ contains an ‘<IMG>’ tag + referencing ‘1.gif’ and an ‘<A>’ tag pointing to external document + ‘2.html’. Say that ‘2.html’ is similar but that its image is + ‘2.gif’ and it links to ‘3.html’. Say this continues up to some + arbitrarily high number. + + If one executes the command: + + wget -r -l 2 http://SITE/1.html + + then ‘1.html’, ‘1.gif’, ‘2.html’, ‘2.gif’, and ‘3.html’ will be + downloaded. As you can see, ‘3.html’ is without its requisite + ‘3.gif’ because Wget is simply counting the number of hops (up to + 2) away from ‘1.html’ in order to determine where to stop the + recursion. However, with this command: + + wget -r -l 2 -p http://SITE/1.html + + all the above files _and_ ‘3.html’’s requisite ‘3.gif’ will be + downloaded. Similarly, + + wget -r -l 1 -p http://SITE/1.html + + will cause ‘1.html’, ‘1.gif’, ‘2.html’, and ‘2.gif’ to be + downloaded. One might think that: + + wget -r -l 0 -p http://SITE/1.html + + would download just ‘1.html’ and ‘1.gif’, but unfortunately this is + not the case, because ‘-l 0’ is equivalent to ‘-l inf’—that is, + infinite recursion. To download a single HTML page (or a handful + of them, all specified on the command-line or in a ‘-i’ URL input + file) and its (or their) requisites, simply leave off ‘-r’ and + ‘-l’: + + wget -p http://SITE/1.html + + Note that Wget will behave as if ‘-r’ had been specified, but only + that single page and its requisites will be downloaded. Links from + that page to external documents will not be followed. Actually, to + download a single page and all its requisites (even if they exist + on separate websites), and make sure the lot displays properly + locally, this author likes to use a few options in addition to + ‘-p’: + + wget -E -H -k -K -p http://SITE/DOCUMENT + + To finish off this topic, it’s worth knowing that Wget’s idea of an + external document link is any URL specified in an ‘<A>’ tag, an + ‘<AREA>’ tag, or a ‘<LINK>’ tag other than ‘<LINK + REL="stylesheet">’. + +‘--strict-comments’ + Turn on strict parsing of HTML comments. The default is to + terminate comments at the first occurrence of ‘-->’. + + According to specifications, HTML comments are expressed as SGML + “declarations”. Declaration is special markup that begins with + ‘<!’ and ends with ‘>’, such as ‘<!DOCTYPE ...>’, that may contain + comments between a pair of ‘--’ delimiters. HTML comments are + “empty declarations”, SGML declarations without any non-comment + text. Therefore, ‘<!--foo-->’ is a valid comment, and so is + ‘<!--one-- --two-->’, but ‘<!--1--2-->’ is not. + + On the other hand, most HTML writers don’t perceive comments as + anything other than text delimited with ‘<!--’ and ‘-->’, which is + not quite the same. For example, something like ‘<!------------>’ + works as a valid comment as long as the number of dashes is a + multiple of four (!). If not, the comment technically lasts until + the next ‘--’, which may be at the other end of the document. + Because of this, many popular browsers completely ignore the + specification and implement what users have come to expect: + comments delimited with ‘<!--’ and ‘-->’. + + Until version 1.9, Wget interpreted comments strictly, which + resulted in missing links in many web pages that displayed fine in + browsers, but had the misfortune of containing non-compliant + comments. Beginning with version 1.9, Wget has joined the ranks of + clients that implements “naive” comments, terminating each comment + at the first occurrence of ‘-->’. + + If, for whatever reason, you want strict comment parsing, use this + option to turn it on. + + +File: wget.info, Node: Recursive Accept/Reject Options, Next: Exit Status, Prev: Recursive Retrieval Options, Up: Invoking + +2.12 Recursive Accept/Reject Options +==================================== + +‘-A ACCLIST --accept ACCLIST’ +‘-R REJLIST --reject REJLIST’ + Specify comma-separated lists of file name suffixes or patterns to + accept or reject (*note Types of Files::). Note that if any of the + wildcard characters, ‘*’, ‘?’, ‘[’ or ‘]’, appear in an element of + ACCLIST or REJLIST, it will be treated as a pattern, rather than a + suffix.

Without this option, Wget + will ignore all the FTP links. + +‘--follow-tags=LIST’ + Wget has an internal table of HTML tag / attribute pairs that it + considers when looking for linked documents during a recursive + retrieval. If a user wants only a subset of those tags to be + considered, however, he or she should be specify such tags in a + comma-separated LIST with this option. + +‘--ignore-tags=LIST’ + This is the opposite of the ‘--follow-tags’ option. To skip + certain HTML tags when recursively looking for documents to + download, specify them in a comma-separated LIST. + + In the past, this option was the best bet for downloading a single + page and its requisites, using a command-line like: + + wget --ignore-tags=a,area -H -k -K -r http://SITE/DOCUMENT + + However, the author of this option came across a page with tags + like ‘<LINK REL="home" HREF="/">’ and came to the realization that + specifying tags to ignore was not enough. One can’t just tell Wget + to ignore ‘<LINK>’, because then stylesheets will not be + downloaded. Now the best bet for downloading a single page and its + requisites is the dedicated ‘--page-requisites’ option. + +‘--ignore-case’ + Ignore case when matching files and directories. This influences + the behavior of -R, -A, -I, and -X options, as well as globbing + implemented when downloading from FTP sites. For example, with + this option, ‘-A "*.txt"’ will match ‘file1.txt’, but also + ‘file2.TXT’, ‘file3.TxT’, and so on. The quotes in the example are + to prevent the shell from expanding the pattern. + +‘-H’ +‘--span-hosts’ + Enable spanning across hosts when doing recursive retrieving (*note + Spanning Hosts::). + +‘-L’ +‘--relative’ + Follow relative links only.

Recursive downloads would virtually always +return 0 (success), regardless of any issues encountered, and +non-recursive fetches only returned the status corresponding to the most +recently-attempted download. + + +File: wget.info, Node: Recursive Download, Next: Following Links, Prev: Invoking, Up: Top + +3 Recursive Download +******************** + +GNU Wget is capable of traversing parts of the Web (or a single HTTP or +FTP server), following links and directory structure. We refer to this +as to “recursive retrieval”, or “recursion”. + + With HTTP URLs, Wget retrieves and parses the HTML or CSS from the +given URL, retrieving the files the document refers to, through markup +like ‘href’ or ‘src’, or CSS URI values specified using the ‘url()’ +functional notation. If the freshly downloaded file is also of type +‘text/html’, ‘application/xhtml+xml’, or ‘text/css’, it will be parsed +and followed further. + + Recursive retrieval of HTTP and HTML/CSS content is “breadth-first”. +This means that Wget first downloads the requested document, then the +documents linked from that document, then the documents linked by them, +and so on. In other words, Wget first downloads the documents at depth +1, then those at depth 2, and so on until the specified maximum depth. + + The maximum “depth” to which the retrieval may descend is specified +with the ‘-l’ option. The default maximum depth is five layers. + + When retrieving an FTP URL recursively, Wget will retrieve all the +data from the given directory tree (including the subdirectories up to +the specified depth) on the remote server, creating its mirror image +locally. FTP retrieval is also limited by the ‘depth’ parameter. +Unlike HTTP recursion, FTP recursion is performed depth-first. + + By default, Wget will create a local directory tree, corresponding to +the one found on the remote server. + + Recursive retrieving can find a number of applications, the most +important of which is mirroring. It is also useful for WWW +presentations, and any other opportunities where slow network +connections should be bypassed by storing the files locally. + + You should be warned that recursive downloads can overload the remote +servers. Because of that, many administrators frown upon them and may +ban access from your site if they detect very fast downloads of big +amounts of content. When downloading from Internet servers, consider +using the ‘-w’ option to introduce a delay between accesses to the +server. The download will take a while longer, but the server +administrator will not be alarmed by your rudeness. + + Of course, recursive download may cause problems on your machine. If +left to run unchecked, it can easily fill up the disk. If downloading +from local network, it can also take bandwidth on the system, as well as +consume memory and CPU. + + Try to specify the criteria that match the kind of download you are +trying to achieve. If you want to download only one page, use +‘--page-requisites’ without any additional recursion. If you want to +download things under one directory, use ‘-np’ to avoid downloading +things from other directories. If you want to download all the files +from one directory, use ‘-l 1’ to make sure the recursion depth never +exceeds one. *Note Following Links::, for more information about this. + + Recursive retrieval should be used with care. Don’t say you were not +warned. + + +File: wget.info, Node: Following Links, Next: Time-Stamping, Prev: Recursive Download, Up: Top + +4 Following Links +***************** + +When retrieving recursively, one does not wish to retrieve loads of +unnecessary data. Most of the time the users bear in mind exactly what +they want to download, and want Wget to follow only specific links. + + For example, if you wish to download the music archive from +‘fly.srk.fer.hr’, you will not want to download all the home pages that +happen to be referenced by an obscure part of the archive. + + Wget possesses several mechanisms that allows you to fine-tune which +links it will follow. + +* Menu: + +* Spanning Hosts:: (Un)limiting retrieval based on host name. +* Types of Files:: Getting only certain files. +* Directory-Based Limits:: Getting only certain directories. +* Relative Links:: Follow relative links only. +* FTP Links:: Following FTP links. + + +File: wget.info, Node: Spanning Hosts, Next: Types of Files, Prev: Following Links, Up: Following Links + +4.1 Spanning Hosts +================== + +Wget’s recursive retrieval normally refuses to visit hosts different +than the one you specified on the command line. This is a reasonable +default; without it, every retrieval would have the potential to turn +your Wget into a small version of google. + + However, visiting different hosts, or “host spanning,” is sometimes a +useful option. Maybe the images are served from a different server. +Maybe you’re mirroring a site that consists of pages interlinked between +three servers. Maybe the server has two equivalent names, and the HTML +pages refer to both interchangeably. + +Span to any host—‘-H’ + + The ‘-H’ option turns on host spanning, thus allowing Wget’s + recursive run to visit any host referenced by a link. Unless + sufficient recursion-limiting criteria are applied depth, these + foreign hosts will typically link to yet more hosts, and so on + until Wget ends up sucking up much more data than you have + intended. + +Limit spanning to certain domains—‘-D’ + + The ‘-D’ option allows you to specify the domains that will be + followed, thus limiting the recursion only to the hosts that belong + to these domains. Obviously, this makes sense only in conjunction + with ‘-H’. A typical example would be downloading the contents of + ‘www.example.com’, but allowing downloads from + ‘images.example.com’, etc.: + + wget -rH -Dexample.com http://www.example.com/ + + You can specify more than one address by separating them with a + comma, e.g. ‘-Ddomain1.com,domain2.com’. + +Keep download off certain domains—‘--exclude-domains’ + + If there are domains you want to exclude specifically, you can do + it with ‘--exclude-domains’, which accepts the same type of + arguments of ‘-D’, but will _exclude_ all the listed domains. For + example, if you want to download all the hosts from ‘foo.edu’ + domain, with the exception of ‘sunsite.foo.edu’, you can do it like + this: + + wget -rH -Dfoo.edu --exclude-domains sunsite.foo.edu \ + http://www.foo.edu/ + + +File: wget.info, Node: Types of Files, Next: Directory-Based Limits, Prev: Spanning Hosts, Up: Following Links + +4.2 Types of Files +================== + +When downloading material from the web, you will often want to restrict +the retrieval to only certain file types. For example, if you are +interested in downloading GIFs, you will not be overjoyed to get loads +of PostScript documents, and vice versa. + + Wget offers two options to deal with this problem. Each option +description lists a short name, a long name, and the equivalent command +in ‘.wgetrc’. + +‘-A ACCLIST’ +‘--accept ACCLIST’ +‘accept = ACCLIST’ +‘--accept-regex URLREGEX’ +‘accept-regex = URLREGEX’ + The argument to ‘--accept’ option is a list of file suffixes or + patterns that Wget will download during recursive retrieval. A + suffix is the ending part of a file, and consists of “normal” + letters, e.g. ‘gif’ or ‘.jpg’. A matching pattern contains + shell-like wildcards, e.g. ‘books*’ or ‘zelazny*196[0-9]*’. + + So, specifying ‘wget -A gif,jpg’ will make Wget download only the + files ending with ‘gif’ or ‘jpg’, i.e. GIFs and JPEGs. On the + other hand, ‘wget -A "zelazny*196[0-9]*"’ will download only files + beginning with ‘zelazny’ and containing numbers from 1960 to 1969 + anywhere within. Look up the manual of your shell for a + description of how pattern matching works. + + Of course, any number of suffixes and patterns can be combined into + a comma-separated list, and given as an argument to ‘-A’. + + The argument to ‘--accept-regex’ option is a regular expression + which is matched against the complete URL. + +‘-R REJLIST’ +‘--reject REJLIST’ +‘reject = REJLIST’ +‘--reject-regex URLREGEX’ +‘reject-regex = URLREGEX’ + The ‘--reject’ option works the same way as ‘--accept’, only its + logic is the reverse; Wget will download all files _except_ the + ones matching the suffixes (or patterns) in the list. + + So, if you want to download a whole page except for the cumbersome + MPEGs and .AU files, you can use ‘wget -R mpg,mpeg,au’. + Analogously, to download all files except the ones beginning with + ‘bjork’, use ‘wget -R "bjork*"’. The quotes are to prevent + expansion by the shell. + + The argument to ‘--accept-regex’ option is a regular expression which +is matched against the complete URL. + +The ‘-A’ and ‘-R’ options may be combined to achieve even better +fine-tuning of which files to retrieve. E.g. ‘wget -A "*zelazny*" -R +.ps’ will download all the files having ‘zelazny’ as a part of their +name, but _not_ the PostScript files. + + Note that these two options do not affect the downloading of HTML +files (as determined by a ‘.htm’ or ‘.html’ filename prefix). This +behavior may not be desirable for all users, and may be changed for +future versions of Wget. + + Note, too, that query strings (strings at the end of a URL beginning +with a question mark (‘?’) are not included as part of the filename for +accept/reject rules, even though these will actually contribute to the +name chosen for the local file. It is expected that a future version of +Wget will provide an option to allow matching against query strings. + + Finally, it’s worth noting that the accept/reject lists are matched +_twice_ against downloaded files: once against the URL’s filename +portion, to determine if the file should be downloaded in the first +place; then, after it has been accepted and successfully downloaded, the +local file’s name is also checked against the accept/reject lists to see +if it should be removed. The rationale was that, since ‘.htm’ and +‘.html’ files are always downloaded regardless of accept/reject rules, +they should be removed _after_ being downloaded and scanned for links, +if they did match the accept/reject lists. However, this can lead to +unexpected results, since the local filenames can differ from the +original URL filenames in the following ways, all of which can change +whether an accept/reject rule matches: + + • If the local file already exists and ‘--no-directories’ was + specified, a numeric suffix will be appended to the original name. + • If ‘--adjust-extension’ was specified, the local filename might + have ‘.html’ appended to it. If Wget is invoked with ‘-E -A.php’, + a filename such as ‘index.php’ will match be accepted, but upon + download will be named ‘index.php.html’, which no longer matches, + and so the file will be deleted. + • Query strings do not contribute to URL matching, but are included + in local filenames, and so _do_ contribute to filename matching. + +This behavior, too, is considered less-than-desirable, and may change in +a future version of Wget. + + +File: wget.info, Node: Directory-Based Limits, Next: Relative Links, Prev: Types of Files, Up: Following Links + +4.3 Directory-Based Limits +========================== + +Regardless of other link-following facilities, it is often useful to +place the restriction of what files to retrieve based on the directories +those files are placed in. There can be many reasons for this—the home +pages may be organized in a reasonable directory structure; or some +directories may contain useless information, e.g. ‘/cgi-bin’ or ‘/dev’ +directories. + + Wget offers three different options to deal with this requirement. +Each option description lists a short name, a long name, and the +equivalent command in ‘.wgetrc’. + +‘-I LIST’ +‘--include LIST’ +‘include_directories = LIST’ + ‘-I’ option accepts a comma-separated list of directories included + in the retrieval. Any other directories will simply be ignored. + The directories are absolute paths. + + So, if you wish to download from ‘http://host/people/bozo/’ + following only links to bozo’s colleagues in the ‘/people’ + directory and the bogus scripts in ‘/cgi-bin’, you can specify: + + wget -I /people,/cgi-bin http://host/people/bozo/ + +‘-X LIST’ +‘--exclude LIST’ +‘exclude_directories = LIST’ + ‘-X’ option is exactly the reverse of ‘-I’—this is a list of + directories _excluded_ from the download. E.g. if you do not want + Wget to download things from ‘/cgi-bin’ directory, specify ‘-X + /cgi-bin’ on the command line. + + The same as with ‘-A’/‘-R’, these two options can be combined to + get a better fine-tuning of downloading subdirectories. E.g. if + you want to load all the files from ‘/pub’ hierarchy except for + ‘/pub/worthless’, specify ‘-I/pub -X/pub/worthless’. + +‘-np’ +‘--no-parent’ +‘no_parent = on’ + The simplest, and often very useful way of limiting directories is + disallowing retrieval of the links that refer to the hierarchy + “above” than the beginning directory, i.e. disallowing ascent to + the parent directory/directories. + + The ‘--no-parent’ option (short ‘-np’) is useful in this case. + Using it guarantees that you will never leave the existing + hierarchy. Supposing you issue Wget with: + + wget -r --no-parent http://somehost/~luzer/my-archive/ + + You may rest assured that none of the references to + ‘/~his-girls-homepage/’ or ‘/~luzer/all-my-mpegs/’ will be + followed. Only the archive you are interested in will be + downloaded. Essentially, ‘--no-parent’ is similar to + ‘-I/~luzer/my-archive’, only it handles redirections in a more + intelligent fashion. + + *Note* that, for HTTP (and HTTPS), the trailing slash is very + important to ‘--no-parent’. HTTP has no concept of a + “directory”—Wget relies on you to indicate what’s a directory and + what isn’t. In ‘http://foo/bar/’, Wget will consider ‘bar’ to be a + directory, while in ‘http://foo/bar’ (no trailing slash), ‘bar’ + will be considered a filename (so ‘--no-parent’ would be + meaningless, as its parent is ‘/’). + + +File: wget.info, Node: Relative Links, Next: FTP Links, Prev: Directory-Based Limits, Up: Following Links + +4.4 Relative Links +================== + +When ‘-L’ is turned on, only the relative links are ever followed. +Relative links are here defined those that do not refer to the web +server root. For example, these links are relative: + + <a href="foo.gif"> + <a href="foo/bar.gif"> + <a href="../foo/bar.gif"> + + These links are not relative: + + <a href="/foo.gif"> + <a href="/foo/bar.gif"> + <a href="http://www.example.com/foo/bar.gif"> + + Using this option guarantees that recursive retrieval will not span +hosts, even without ‘-H’. In simple cases it also allows downloads to +“just work” without having to convert links. + + This option is probably not very useful and might be removed in a +future release. + + +File: wget.info, Node: FTP Links, Prev: Relative Links, Up: Following Links + +4.5 Following FTP Links +======================= + +The rules for FTP are somewhat specific, as it is necessary for them to +be. FTP links in HTML documents are often included for purposes of +reference, and it is often inconvenient to download them by default. + + To have FTP links followed from HTML documents, you need to specify +the ‘--follow-ftp’ option. Having done that, FTP links will span hosts +regardless of ‘-H’ setting. This is logical, as FTP links rarely point +to the same host where the HTTP server resides. For similar reasons, +the ‘-L’ options has no effect on such downloads. On the other hand, +domain acceptance (‘-D’) and suffix rules (‘-A’ and ‘-R’) apply +normally. + + Also note that followed links to FTP directories will not be +retrieved recursively further. + + +File: wget.info, Node: Time-Stamping, Next: Startup File, Prev: Following Links, Up: Top + +5 Time-Stamping +*************** + +One of the most important aspects of mirroring information from the +Internet is updating your archives. + + Downloading the whole archive again and again, just to replace a few +changed files is expensive, both in terms of wasted bandwidth and money, +and the time to do the update. This is why all the mirroring tools +offer the option of incremental updating. + + Such an updating mechanism means that the remote server is scanned in +search of “new” files. Only those new files will be downloaded in the +place of the old ones. + + A file is considered new if one of these two conditions are met: + + 1. A file of that name does not already exist locally. + + 2. A file of that name does exist, but the remote file was modified + more recently than the local file. + + To implement this, the program needs to be aware of the time of last +modification of both local and remote files. We call this information +the “time-stamp” of a file. + + The time-stamping in GNU Wget is turned on using ‘--timestamping’ +(‘-N’) option, or through ‘timestamping = on’ directive in ‘.wgetrc’. +With this option, for each file it intends to download, Wget will check +whether a local file of the same name exists. If it does, and the +remote file is not newer, Wget will not download it. + + If the local file does not exist, or the sizes of the files do not +match, Wget will download the remote file no matter what the time-stamps +say. + +* Menu: + +* Time-Stamping Usage:: +* HTTP Time-Stamping Internals:: +* FTP Time-Stamping Internals:: + + +File: wget.info, Node: Time-Stamping Usage, Next: HTTP Time-Stamping Internals, Prev: Time-Stamping, Up: Time-Stamping + +5.1 Time-Stamping Usage +======================= + +The usage of time-stamping is simple. Say you would like to download a +file so that it keeps its date of modification. + + wget -S http://www.gnu.ai.mit.edu/ + + A simple ‘ls -l’ shows that the timestamp on the local file equals +the state of the ‘Last-Modified’ header, as returned by the server. As +you can see, the time-stamping info is preserved locally, even without +‘-N’ (at least for HTTP). + + Several days later, you would like Wget to check if the remote file +has changed, and download it if it has. + + wget -N http://www.gnu.ai.mit.edu/ + + Wget will ask the server for the last-modified date. If the local +file has the same timestamp as the server, or a newer one, the remote +file will not be re-fetched. However, if the remote file is more +recent, Wget will proceed to fetch it. + + The same goes for FTP. For example: + + wget "ftp://ftp.ifi.uio.no/pub/emacs/gnus/*" + + (The quotes around that URL are to prevent the shell from trying to +interpret the ‘*’.) + + After download, a local directory listing will show that the +timestamps match those on the remote server. Reissuing the command with +‘-N’ will make Wget re-fetch _only_ the files that have been modified +since the last download. + + If you wished to mirror the GNU archive every week, you would use a +command like the following, weekly: + + wget --timestamping -r ftp://ftp.gnu.org/pub/gnu/ + + Note that time-stamping will only work for files for which the server +gives a timestamp. For HTTP, this depends on getting a ‘Last-Modified’ +header. For FTP, this depends on getting a directory listing with dates +in a format that Wget can parse (*note FTP Time-Stamping Internals::). + + +File: wget.info, Node: HTTP Time-Stamping Internals, Next: FTP Time-Stamping Internals, Prev: Time-Stamping Usage, Up: Time-Stamping + +5.2 HTTP Time-Stamping Internals +================================ + +Time-stamping in HTTP is implemented by checking of the ‘Last-Modified’ +header. If you wish to retrieve the file ‘foo.html’ through HTTP, Wget +will check whether ‘foo.html’ exists locally. If it doesn’t, ‘foo.html’ +will be retrieved unconditionally. + + If the file does exist locally, Wget will first check its local +time-stamp (similar to the way ‘ls -l’ checks it), and then send a +‘HEAD’ request to the remote server, demanding the information on the +remote file. + + The ‘Last-Modified’ header is examined to find which file was +modified more recently (which makes it “newer”). If the remote file is +newer, it will be downloaded; if it is older, Wget will give up.(1) + + When ‘--backup-converted’ (‘-K’) is specified in conjunction with +‘-N’, server file ‘X’ is compared to local file ‘X.orig’, if extant, +rather than being compared to local file ‘X’, which will always differ +if it’s been converted by ‘--convert-links’ (‘-k’). + + Arguably, HTTP time-stamping should be implemented using the +‘If-Modified-Since’ request. + + ---------- Footnotes ---------- + + (1) As an additional check, Wget will look at the ‘Content-Length’ +header, and compare the sizes; if they are not the same, the remote file +will be downloaded no matter what the time-stamp says. + + +File: wget.info, Node: FTP Time-Stamping Internals, Prev: HTTP Time-Stamping Internals, Up: Time-Stamping + +5.3 FTP Time-Stamping Internals +=============================== + +In theory, FTP time-stamping works much the same as HTTP, only FTP has +no headers—time-stamps must be ferreted out of directory listings. + + If an FTP download is recursive or uses globbing, Wget will use the +FTP ‘LIST’ command to get a file listing for the directory containing +the desired file(s). It will try to analyze the listing, treating it +like Unix ‘ls -l’ output, extracting the time-stamps. The rest is +exactly the same as for HTTP. Note that when retrieving individual +files from an FTP server without using globbing or recursion, listing +files will not be downloaded (and thus files will not be time-stamped) +unless ‘-N’ is specified. + + Assumption that every directory listing is a Unix-style listing may +sound extremely constraining, but in practice it is not, as many +non-Unix FTP servers use the Unixoid listing format because most (all?) +of the clients understand it. Bear in mind that RFC959 defines no +standard way to get a file list, let alone the time-stamps. We can only +hope that a future standard will define this. + + Another non-standard solution includes the use of ‘MDTM’ command that +is supported by some FTP servers (including the popular ‘wu-ftpd’), +which returns the exact time of the specified file. Wget may support +this command in the future. + + +File: wget.info, Node: Startup File, Next: Examples, Prev: Time-Stamping, Up: Top + +6 Startup File +************** + +Once you know how to change default settings of Wget through command +line arguments, you may wish to make some of those settings permanent. +You can do that in a convenient way by creating the Wget startup +file—‘.wgetrc’. + + Besides ‘.wgetrc’ is the “main” initialization file, it is convenient +to have a special facility for storing passwords. Thus Wget reads and +interprets the contents of ‘$HOME/.netrc’, if it finds it. You can find +‘.netrc’ format in your system manuals. + + Wget reads ‘.wgetrc’ upon startup, recognizing a limited set of +commands. + +* Menu: + +* Wgetrc Location:: Location of various wgetrc files. +* Wgetrc Syntax:: Syntax of wgetrc. +* Wgetrc Commands:: List of available commands. +* Sample Wgetrc:: A wgetrc example. + + +File: wget.info, Node: Wgetrc Location, Next: Wgetrc Syntax, Prev: Startup File, Up: Startup File + +6.1 Wgetrc Location +=================== + +When initializing, Wget will look for a “global” startup file, +‘/usr/local/etc/wgetrc’ by default (or some prefix other than +‘/usr/local’, if Wget was not installed there) and read commands from +there, if it exists. + + Then it will look for the user’s file. If the environmental variable +‘WGETRC’ is set, Wget will try to load that file. Failing that, no +further attempts will be made. + + If ‘WGETRC’ is not set, Wget will try to load ‘$HOME/.wgetrc’. + + The fact that user’s settings are loaded after the system-wide ones +means that in case of collision user’s wgetrc _overrides_ the +system-wide wgetrc (in ‘/usr/local/etc/wgetrc’ by default).

Just type: + + wget http://fly.srk.fer.hr/ + + • But what will happen if the connection is slow, and the file is + lengthy? The connection will probably fail before the whole file + is retrieved, more than once. In this case, Wget will try getting + the file until it either gets the whole of it, or exceeds the + default number of retries (this being 20). It is easy to change + the number of tries to 45, to insure that the whole file will + arrive safely: + + wget --tries=45 http://fly.srk.fer.hr/jpg/flyweb.jpg + + • Now let’s leave Wget to work in the background, and write its + progress to log file ‘log’. It is tiring to type ‘--tries’, so we + shall use ‘-t’. + + wget -t 45 -o log http://fly.srk.fer.hr/jpg/flyweb.jpg & + + The ampersand at the end of the line makes sure that Wget works in + the background. To unlimit the number of retries, use ‘-t inf’. + + • The usage of FTP is as simple. Wget will take care of login and + password. + + wget ftp://gnjilux.srk.fer.hr/welcome.msg + + • If you specify a directory, Wget will retrieve the directory + listing, parse it and convert it to HTML.

Use + the ‘-i’ switch: + + wget -i FILE + + If you specify ‘-’ as file name, the URLs will be read from + standard input. + + • Create a five levels deep mirror image of the GNU web site, with + the same directory structure the original has, with only one try + per document, saving the log of the activities to ‘gnulog’: + + wget -r https://www.gnu.org/ -o gnulog + + • The same as the above, but convert the links in the downloaded + files to point to local files, so you can view the documents + off-line: + + wget --convert-links -r https://www.gnu.org/ -o gnulog + + • Retrieve only one HTML page, but make sure that all the elements + needed for the page to be displayed, such as inline images and + external style sheets, are also downloaded. Also make sure the + downloaded page references the downloaded links. + + wget -p --convert-links http://www.example.com/dir/page.html + + The HTML page will be saved to ‘www.example.com/dir/page.html’, and + the images, stylesheets, etc., somewhere under ‘www.example.com/’, + depending on where they were on the remote server. + + • The same as the above, but without the ‘www.example.com/’ + directory. In fact, I don’t want to have all those random server + directories anyway—just save _all_ those files under a ‘download/’ + subdirectory of the current directory. + + wget -p --convert-links -nH -nd -Pdownload \ + http://www.example.com/dir/page.html + + • Retrieve the index.html of ‘www.lycos.com’, showing the original + server headers: + + wget -S http://www.lycos.com/ + + • Save the server headers with the file, perhaps for post-processing. + + wget --save-headers http://www.lycos.com/ + more index.html + + • Retrieve the first two levels of ‘wuarchive.wustl.edu’, saving them + to ‘/tmp’. + + wget -r -l2 -P/tmp ftp://wuarchive.wustl.edu/ + + • You want to download all the GIFs from a directory on an HTTP + server. You tried ‘wget http://www.example.com/dir/*.gif’, but + that didn’t work because HTTP retrieval does not support globbing. + In that case, use: + + wget -r -l1 --no-parent -A.gif http://www.example.com/dir/ + + More verbose, but the effect is the same. ‘-r -l1’ means to + retrieve recursively (*note Recursive Download::), with maximum + depth of 1. ‘--no-parent’ means that references to the parent + directory are ignored (*note Directory-Based Limits::), and + ‘-A.gif’ means to download only the GIF files. ‘-A "*.gif"’ would + have worked too. + + • Suppose you were in the middle of downloading, when Wget was + interrupted. Now you do not want to clobber the files already + present. It would be: + + wget -nc -r https://www.gnu.org/ + + • If you want to encode your own username and password to HTTP or + FTP, use the appropriate URL syntax (*note URL Format::). + + wget ftp://hniksic:mypassword@unix.example.com/.emacs + + Note, however, that this usage is not advisable on multi-user + systems because it reveals your password to anyone who looks at the + output of ‘ps’. + + • You would like the output documents to go to standard output + instead of to files? + + wget -O - http://jagor.srce.hr/ http://www.srce.hr/ + + You can also combine the two options and make pipelines to retrieve + the documents from remote hotlists: + + wget -O - http://cool.list.com/ | wget --force-html -i - + + +File: wget.info, Node: Very Advanced Usage, Prev: Advanced Usage, Up: Examples + +7.3 Very Advanced Usage +======================= + + • If you wish Wget to keep a mirror of a page (or FTP + subdirectories), use ‘--mirror’ (‘-m’), which is the shorthand for + ‘-r -l inf -N’. You can put Wget in the crontab file asking it to + recheck a site each Sunday: + + crontab + 0 0 * * 0 wget --mirror https://www.gnu.org/ -o /home/me/weeklog + + • In addition to the above, you want the links to be converted for + local viewing. But, after having read this manual, you know that + link conversion doesn’t play well with timestamping, so you also + want Wget to back up the original HTML files before the conversion. + Wget invocation would look like this: + + wget --mirror --convert-links --backup-converted \ + https://www.gnu.org/ -o /home/me/weeklog + + • But you’ve also noticed that local viewing doesn’t work all that + well when HTML files are saved under extensions other than ‘.html’, + perhaps because they were served as ‘index.cgi’.

One typical use of proxies is +lightening network load for users behind a slow connection. This is +achieved by channeling all HTTP and FTP requests through the proxy which +caches the transferred data. When a cached resource is requested again, +proxy will return the data from cache. Another use for proxies is for +companies that separate (for security reasons) their internal networks +from the rest of Internet. In order to obtain information from the Web, +their users connect and retrieve remote data using an authorized proxy. + + Wget supports proxies for both HTTP and FTP retrievals. The standard +way to specify proxy location, which Wget recognizes, is using the +following environment variables: + +‘http_proxy’ +‘https_proxy’ + If set, the ‘http_proxy’ and ‘https_proxy’ variables should contain + the URLs of the proxies for HTTP and HTTPS connections + respectively. + +‘ftp_proxy’ + This variable should contain the URL of the proxy for FTP + connections. It is quite common that ‘http_proxy’ and ‘ftp_proxy’ + are set to the same URL. + +‘no_proxy’ + This variable should contain a comma-separated list of domain + extensions proxy should _not_ be used for. For instance, if the + value of ‘no_proxy’ is ‘.mit.edu’, proxy will not be used to + retrieve documents from MIT. + + In addition to the environment variables, proxy location and settings +may be specified from within Wget itself. + +‘--no-proxy’ +‘proxy = on/off’ + This option and the corresponding command may be used to suppress + the use of proxy, even if the appropriate environment variables are + set. + +‘http_proxy = URL’ +‘https_proxy = URL’ +‘ftp_proxy = URL’ +‘no_proxy = STRING’ + These startup file variables allow you to override the proxy + settings specified by the environment. + + Some proxy servers require authorization to enable you to use them. +The authorization consists of “username” and “password”, which must be +sent by Wget. As with HTTP authorization, several authentication +schemes exist. For proxy authorization only the ‘Basic’ authentication +scheme is currently implemented. + + You may specify your username and password either through the proxy +URL or through the command-line options. Assuming that the company’s +proxy is located at ‘proxy.company.com’ at port 8001, a proxy URL +location containing authorization data might look like this: + + http://hniksic:mypassword@proxy.company.com:8001/ + + Alternatively, you may use the ‘proxy-user’ and ‘proxy-password’ +options, and the equivalent ‘.wgetrc’ settings ‘proxy_user’ and +‘proxy_password’ to set the proxy username and password. + + +File: wget.info, Node: Distribution, Next: Web Site, Prev: Proxies, Up: Various + +8.2 Distribution +================ + +Like all GNU utilities, the latest version of Wget can be found at the +master GNU archive site ftp.gnu.org, and its mirrors.

Come check it out! + + +File: wget.info, Node: Reporting Bugs, Next: Portability, Prev: Internet Relay Chat, Up: Various + +8.6 Reporting Bugs +================== + +You are welcome to submit bug reports via the GNU Wget bug tracker (see +<https://savannah.gnu.org/bugs/?func=additem&group=wget>) or to our +mailing list <bug-wget@gnu.org>. + + Visit <https://lists.gnu.org/mailman/listinfo/bug-wget> to get more +info (how to subscribe, list archives, ...). + + Before actually submitting a bug report, please try to follow a few +simple guidelines. + + 1. Please try to ascertain that the behavior you see really is a bug. + If Wget crashes, it’s a bug. If Wget does not behave as + documented, it’s a bug. If things work strange, but you are not + sure about the way they are supposed to work, it might well be a + bug, but you might want to double-check the documentation and the + mailing lists (*note Mailing Lists::). + + 2. Try to repeat the bug in as simple circumstances as possible. E.g. + if Wget crashes while downloading ‘wget -rl0 -kKE -t5 --no-proxy + http://example.com -o /tmp/log’, you should try to see if the crash + is repeatable, and if will occur with a simpler set of options. + You might even try to start the download at the page where the + crash occurred to see if that page somehow triggered the crash. + + Also, while I will probably be interested to know the contents of + your ‘.wgetrc’ file, just dumping it into the debug message is + probably a bad idea. Instead, you should first try to see if the + bug repeats with ‘.wgetrc’ moved out of the way. Only if it turns + out that ‘.wgetrc’ settings affect the bug, mail me the relevant + parts of the file. + + 3. Please start Wget with ‘-d’ option and send us the resulting output + (or relevant parts thereof). If Wget was compiled without debug + support, recompile it—it is _much_ easier to trace bugs with debug + support on. + + Note: please make sure to remove any potentially sensitive + information from the debug log before sending it to the bug + address. The ‘-d’ won’t go out of its way to collect sensitive + information, but the log _will_ contain a fairly complete + transcript of Wget’s communication with the server, which may + include passwords and pieces of downloaded data. Since the bug + address is publicly archived, you may assume that all bug reports + are visible to the public. + + 4. If Wget has crashed, try to run it in a debugger, e.g. ‘gdb `which + wget` core’ and type ‘where’ to get the backtrace. This may not + work if the system administrator has disabled core files, but it is + safe to try. + + +File: wget.info, Node: Portability, Next: Signals, Prev: Reporting Bugs, Up: Various + +8.7 Portability +=============== + +Like all GNU software, Wget works on the GNU system. However, since it +uses GNU Autoconf for building and configuring, and mostly avoids using +“special” features of any particular Unix, it should compile (and work) +on all common Unix flavors. + + Various Wget versions have been compiled and tested under many kinds +of Unix systems, including GNU/Linux, Solaris, SunOS 4.x, Mac OS X, OSF +(aka Digital Unix or Tru64), Ultrix, *BSD, IRIX, AIX, and others. Some +of those systems are no longer in widespread use and may not be able to +support recent versions of Wget. If Wget fails to compile on your +system, we would like to know about it. + + Thanks to kind contributors, this version of Wget compiles and works +on 32-bit Microsoft Windows platforms. It has been compiled +successfully using MS Visual C++ 6.0, Watcom, Borland C, and GCC +compilers. Naturally, it is crippled of some features available on +Unix, but it should work as a substitute for people stuck with Windows. +Note that Windows-specific portions of Wget are not guaranteed to be +supported in the future, although this has been the case in practice for +many years now. All questions and problems in Windows usage should be +reported to Wget mailing list at <wget@sunsite.dk> where the volunteers +who maintain the Windows-related features might look at them. + + Support for building on MS-DOS via DJGPP has been contributed by +Gisle Vanem; a port to VMS is maintained by Steven Schweda, and is +available at <https://antinode.info/dec/sw/wget.html>. + + +File: wget.info, Node: Signals, Prev: Portability, Up: Various + +8.8 Signals +=========== + +Since the purpose of Wget is background work, it catches the hangup +signal (‘SIGHUP’) and ignores it. If the output was on standard output, +it will be redirected to a file named ‘wget-log’. Otherwise, ‘SIGHUP’ +is ignored. This is convenient when you wish to redirect the output of +Wget after having started it. + + $ wget http://www.gnus.org/dist/gnus.tar.gz & + ... + $ kill -HUP %% + SIGHUP received, redirecting output to `wget-log'. + + Other than that, Wget will not try to interfere with signals in any +way. ‘C-c’, ‘kill -TERM’ and ‘kill -KILL’ should kill it alike. + + +File: wget.info, Node: Appendices, Next: Copying this manual, Prev: Various, Up: Top + +9 Appendices +************ + +This chapter contains some references I consider useful. + +* Menu: + +* Robot Exclusion:: Wget’s support for RES. +* Security Considerations:: Security with Wget. +* Contributors:: People who helped. + + +File: wget.info, Node: Robot Exclusion, Next: Security Considerations, Prev: Appendices, Up: Appendices + +9.1 Robot Exclusion +=================== + +It is extremely easy to make Wget wander aimlessly around a web site, +sucking all the available data in progress. ‘wget -r SITE’, and you’re +set. Great? Not for the server admin. + + As long as Wget is only retrieving static pages, and doing it at a +reasonable rate (see the ‘--wait’ option), there’s not much of a +problem. The trouble is that Wget can’t tell the difference between the +smallest static page and the most demanding CGI. A site I know has a +section handled by a CGI Perl script that converts Info files to HTML on +the fly. The script is slow, but works well enough for human users +viewing an occasional Info file. However, when someone’s recursive Wget +download stumbles upon the index page that links to all the Info files +through the script, the system is brought to its knees without providing +anything useful to the user (This task of converting Info files could be +done locally and access to Info documentation for all installed GNU +software on a system is available from the ‘info’ command). + + To avoid this kind of accident, as well as to preserve privacy for +documents that need to be protected from well-behaved robots, the +concept of “robot exclusion” was invented. The idea is that the server +administrators and document authors can specify which portions of the +site they wish to protect from robots and those they will permit access. + + The most popular mechanism, and the de facto standard supported by +all the major robots, is the “Robots Exclusion Standard” (RES) written +by Martijn Koster et al. in 1994. It specifies the format of a text +file containing directives that instruct the robots which URL paths to +avoid. To be found by the robots, the specifications must be placed in +‘/robots.txt’ in the server root, which the robots are expected to +download and parse. + + Although Wget is not a web robot in the strictest sense of the word, +it can download large parts of the site without the user’s intervention +to download an individual page. Because of that, Wget honors RES when +downloading recursively. For instance, when you issue: + + wget -r http://www.example.com/ + + First the index of ‘www.example.com’ will be downloaded. If Wget +finds that it wants to download more documents from that server, it will +request ‘http://www.example.com/robots.txt’ and, if found, use it for +further downloads. ‘robots.txt’ is loaded only once per each server. + + Until version 1.8, Wget supported the first version of the standard, +written by Martijn Koster in 1994 and available at +<http://www.robotstxt.org/orig.html>. As of version 1.8, Wget has +supported the additional directives specified in the internet draft +‘<draft-koster-robots-00.txt>’ titled “A Method for Web Robots Control”. +The draft, which has as far as I know never made to an RFC, is available +at <http://www.robotstxt.org/norobots-rfc.txt>. + + This manual no longer includes the text of the Robot Exclusion +Standard. + + The second, less known mechanism, enables the author of an individual +document to specify whether they want the links from the file to be +followed by a robot. This is achieved using the ‘META’ tag, like this: + + <meta name="robots" content="nofollow"> + + This is explained in some detail at +<http://www.robotstxt.org/meta.html>. Wget supports this method of +robot exclusion in addition to the usual ‘/robots.txt’ exclusion. + + If you know what you are doing and really really wish to turn off the +robot exclusion, set the ‘robots’ variable to ‘off’ in your ‘.wgetrc’. +You can achieve the same effect from the command line using the ‘-e’ +switch, e.g. ‘wget -e robots=off URL...’. + + +File: wget.info, Node: Security Considerations, Next: Contributors, Prev: Robot Exclusion, Up: Appendices + +9.2 Security Considerations +=========================== + +When using Wget, you must be aware that it sends unencrypted passwords +through the network, which may present a security problem. Here are the +main issues, and some solutions. + + 1. The passwords on the command line are visible using ‘ps’. The best + way around it is to use ‘wget -i -’ and feed the URLs to Wget’s + standard input, each on a separate line, terminated by ‘C-d’. + Another workaround is to use ‘.netrc’ to store passwords; however, + storing unencrypted passwords is also considered a security risk. + + 2. Using the insecure “basic” authentication scheme, unencrypted + passwords are transmitted through the network routers and gateways. + + 3. The FTP passwords are also in no way encrypted. There is no good + solution for this at the moment. + + 4. Although the “normal” output of Wget tries to hide the passwords, + debugging logs show them, in all forms. This problem is avoided by + being careful when you send debug logs (yes, even when you send + them to me). + + +File: wget.info, Node: Contributors, Prev: Security Considerations, Up: Appendices + +9.3 Contributors +================ + +GNU Wget was written by Hrvoje Nikšić <hniksic@xemacs.org>, + + However, the development of Wget could never have gone as far as it +has, were it not for the help of many people, either with bug reports, +feature proposals, patches, or letters saying “Thanks!”. + + Special thanks goes to the following people (no particular order): + + • Dan Harkless—contributed a lot of code and documentation of + extremely high quality, as well as the ‘--page-requisites’ and + related options. He was the principal maintainer for some time and + released Wget 1.6. + + • Ian Abbott—contributed bug fixes, Windows-related fixes, and + provided a prototype implementation of the breadth-first recursive + download. Co-maintained Wget during the 1.8 release cycle. + + • The dotsrc.org crew, in particular Karsten Thygesen—donated system + resources such as the mailing list, web space, FTP space, and + version control repositories, along with a lot of time to make + these actually work. Christian Reiniger was of invaluable help + with setting up Subversion. + + • Heiko Herold—provided high-quality Windows builds and contributed + bug and build reports for many years. + + • Shawn McHorse—bug reports and patches. + + • Kaveh R. Ghazi—on-the-fly ‘ansi2knr’-ization. Lots of portability + fixes. + + • Gordon Matzigkeit—‘.netrc’ support. + + • Zlatko Čalušić, Tomislav Vujec and Dražen Kačar—feature suggestions + and “philosophical” discussions. + + • Darko Budor—initial port to Windows. + + • Antonio Rosella—help and suggestions, plus the initial Italian + translation. + + • Tomislav Petrović, Mario Mikočević—many bug reports and + suggestions. + + • Françis Pinard—many thorough bug reports and discussions. + + • Karl Eichwalder—lots of help with internationalization, Makefile + layout and many other things. + + • Junio Hamano—donated support for Opie and HTTP ‘Digest’ + authentication. + + • Mauro Tortonesi—improved IPv6 support, adding support for dual + family systems. Refactored and enhanced FTP IPv6 code. Maintained + GNU Wget from 2004–2007. + + • Christopher G. Lewis—maintenance of the Windows version of GNU + WGet. + + • Gisle Vanem—many helpful patches and improvements, especially for + Windows and MS-DOS support. + + • Ralf Wildenhues—contributed patches to convert Wget to use Automake + as part of its build process, and various bugfixes. + + • Steven Schubiger—Many helpful patches, bugfixes and improvements. + Notably, conversion of Wget to use the Gnulib quotes and quoteargs + modules, and the addition of password prompts at the console, via + the Gnulib getpasswd-gnu module. + + • Ted Mielczarek—donated support for CSS. + + • Saint Xavier—Support for IRIs (RFC 3987). + + • Tim Rühsen—Loads of helpful patches, especially fuzzing support and + Continuous Integration. Maintainer since 2014. + + • Darshit Shah—Many helpful patches. Community support on various + platforms. Maintainer since 2014. + + • People who provided donations for development—including Brian + Gough. + + The following people have provided patches, bug/build reports, useful +suggestions, beta testing services, fan mail and all the other things +that make maintenance so much fun: + + Tim Adam, Adrian Aichner, Martin Baehr, Dieter Baron, Roger Beeman, +Dan Berger, T.

PREAMBLE + + The purpose of this License is to make a manual, textbook, or other + functional and useful document “free” in the sense of freedom: to + assure everyone the effective freedom to copy and redistribute it, + with or without modifying it, either commercially or + noncommercially. Secondarily, this License preserves for the + author and publisher a way to get credit for their work, while not + being considered responsible for modifications made by others. + + This License is a kind of “copyleft”, which means that derivative + works of the document must themselves be free in the same sense. + It complements the GNU General Public License, which is a copyleft + license designed for free software. + + We have designed this License in order to use it for manuals for + free software, because free software needs free documentation: a + free program should come with manuals providing the same freedoms + that the software does. But this License is not limited to + software manuals; it can be used for any textual work, regardless + of subject matter or whether it is published as a printed book. We + recommend this License principally for works whose purpose is + instruction or reference. + + 1. APPLICABILITY AND DEFINITIONS + + This License applies to any manual or other work, in any medium, + that contains a notice placed by the copyright holder saying it can + be distributed under the terms of this License. Such a notice + grants a world-wide, royalty-free license, unlimited in duration, + to use that work under the conditions stated herein. The + “Document”, below, refers to any such manual or work. Any member + of the public is a licensee, and is addressed as “you”. You accept + the license if you copy, modify or distribute the work in a way + requiring permission under copyright law. + + A “Modified Version” of the Document means any work containing the + Document or a portion of it, either copied verbatim, or with + modifications and/or translated into another language. + + A “Secondary Section” is a named appendix or a front-matter section + of the Document that deals exclusively with the relationship of the + publishers or authors of the Document to the Document’s overall + subject (or to related matters) and contains nothing that could + fall directly within that overall subject. (Thus, if the Document + is in part a textbook of mathematics, a Secondary Section may not + explain any mathematics.) The relationship could be a matter of + historical connection with the subject or with related matters, or + of legal, commercial, philosophical, ethical or political position + regarding them. + + The “Invariant Sections” are certain Secondary Sections whose + titles are designated, as being those of Invariant Sections, in the + notice that says that the Document is released under this License. + If a section does not fit the above definition of Secondary then it + is not allowed to be designated as Invariant. The Document may + contain zero Invariant Sections. If the Document does not identify + any Invariant Sections then there are none. + + The “Cover Texts” are certain short passages of text that are + listed, as Front-Cover Texts or Back-Cover Texts, in the notice + that says that the Document is released under this License. A + Front-Cover Text may be at most 5 words, and a Back-Cover Text may + be at most 25 words. + + A “Transparent” copy of the Document means a machine-readable copy, + represented in a format whose specification is available to the + general public, that is suitable for revising the document + straightforwardly with generic text editors or (for images composed + of pixels) generic paint programs or (for drawings) some widely + available drawing editor, and that is suitable for input to text + formatters or for automatic translation to a variety of formats + suitable for input to text formatters. A copy made in an otherwise + Transparent file format whose markup, or absence of markup, has + been arranged to thwart or discourage subsequent modification by + readers is not Transparent. An image format is not Transparent if + used for any substantial amount of text. A copy that is not + “Transparent” is called “Opaque”. + + Examples of suitable formats for Transparent copies include plain + ASCII without markup, Texinfo input format, LaTeX input format, + SGML or XML using a publicly available DTD, and standard-conforming + simple HTML, PostScript or PDF designed for human modification. + Examples of transparent image formats include PNG, XCF and JPG. + Opaque formats include proprietary formats that can be read and + edited only by proprietary word processors, SGML or XML for which + the DTD and/or processing tools are not generally available, and + the machine-generated HTML, PostScript or PDF produced by some word + processors for output purposes only. + + The “Title Page” means, for a printed book, the title page itself, + plus such following pages as are needed to hold, legibly, the + material this License requires to appear in the title page. For + works in formats which do not have any title page as such, “Title + Page” means the text near the most prominent appearance of the + work’s title, preceding the beginning of the body of the text. + + The “publisher” means any person or entity that distributes copies + of the Document to the public. + + A section “Entitled XYZ” means a named subunit of the Document + whose title either is precisely XYZ or contains XYZ in parentheses + following text that translates XYZ in another language. (Here XYZ + stands for a specific section name mentioned below, such as + “Acknowledgements”, “Dedications”, “Endorsements”, or “History”.) + To “Preserve the Title” of such a section when you modify the + Document means that it remains a section “Entitled XYZ” according + to this definition. + + The Document may include Warranty Disclaimers next to the notice + which states that this License applies to the Document. These + Warranty Disclaimers are considered to be included by reference in + this License, but only as regards disclaiming warranties: any other + implication that these Warranty Disclaimers may have is void and + has no effect on the meaning of this License. + + 2. VERBATIM COPYING + + You may copy and distribute the Document in any medium, either + commercially or noncommercially, provided that this License, the + copyright notices, and the license notice saying this License + applies to the Document are reproduced in all copies, and that you + add no other conditions whatsoever to those of this License. You + may not use technical measures to obstruct or control the reading + or further copying of the copies you make or distribute. However, + you may accept compensation in exchange for copies. If you + distribute a large enough number of copies you must also follow the + conditions in section 3. + + You may also lend copies, under the same conditions stated above, + and you may publicly display copies. + + 3. COPYING IN QUANTITY + + If you publish printed copies (or copies in media that commonly + have printed covers) of the Document, numbering more than 100, and + the Document’s license notice requires Cover Texts, you must + enclose the copies in covers that carry, clearly and legibly, all + these Cover Texts: Front-Cover Texts on the front cover, and + Back-Cover Texts on the back cover. Both covers must also clearly + and legibly identify you as the publisher of these copies. The + front cover must present the full title with all words of the title + equally prominent and visible. You may add other material on the + covers in addition. Copying with changes limited to the covers, as + long as they preserve the title of the Document and satisfy these + conditions, can be treated as verbatim copying in other respects. + + If the required texts for either cover are too voluminous to fit + legibly, you should put the first ones listed (as many as fit + reasonably) on the actual cover, and continue the rest onto + adjacent pages. + + If you publish or distribute Opaque copies of the Document + numbering more than 100, you must either include a machine-readable + Transparent copy along with each Opaque copy, or state in or with + each Opaque copy a computer-network location from which the general + network-using public has access to download using public-standard + network protocols a complete Transparent copy of the Document, free + of added material. If you use the latter option, you must take + reasonably prudent steps, when you begin distribution of Opaque + copies in quantity, to ensure that this Transparent copy will + remain thus accessible at the stated location until at least one + year after the last time you distribute an Opaque copy (directly or + through your agents or retailers) of that edition to the public. + + It is requested, but not required, that you contact the authors of + the Document well before redistributing any large number of copies, + to give them a chance to provide you with an updated version of the + Document. + + 4. MODIFICATIONS + + You may copy and distribute a Modified Version of the Document + under the conditions of sections 2 and 3 above, provided that you + release the Modified Version under precisely this License, with the + Modified Version filling the role of the Document, thus licensing + distribution and modification of the Modified Version to whoever + possesses a copy of it. In addition, you must do these things in + the Modified Version: + + A. Use in the Title Page (and on the covers, if any) a title + distinct from that of the Document, and from those of previous + versions (which should, if there were any, be listed in the + History section of the Document). You may use the same title + as a previous version if the original publisher of that + version gives permission. + + B. List on the Title Page, as authors, one or more persons or + entities responsible for authorship of the modifications in + the Modified Version, together with at least five of the + principal authors of the Document (all of its principal + authors, if it has fewer than five), unless they release you + from this requirement. + + C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. + + D. Preserve all the copyright notices of the Document. + + E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. + + F. Include, immediately after the copyright notices, a license + notice giving the public permission to use the Modified + Version under the terms of this License, in the form shown in + the Addendum below. + + G. Preserve in that license notice the full lists of Invariant + Sections and required Cover Texts given in the Document’s + license notice. + + H. Include an unaltered copy of this License. + + I. Preserve the section Entitled “History”, Preserve its Title, + and add to it an item stating at least the title, year, new + authors, and publisher of the Modified Version as given on the + Title Page. If there is no section Entitled “History” in the + Document, create one stating the title, year, authors, and + publisher of the Document as given on its Title Page, then add + an item describing the Modified Version as stated in the + previous sentence. + + J. Preserve the network location, if any, given in the Document + for public access to a Transparent copy of the Document, and + likewise the network locations given in the Document for + previous versions it was based on. These may be placed in the + “History” section. You may omit a network location for a work + that was published at least four years before the Document + itself, or if the original publisher of the version it refers + to gives permission. + + K. For any section Entitled “Acknowledgements” or “Dedications”, + Preserve the Title of the section, and preserve in the section + all the substance and tone of each of the contributor + acknowledgements and/or dedications given therein. + + L. Preserve all the Invariant Sections of the Document, unaltered + in their text and in their titles. Section numbers or the + equivalent are not considered part of the section titles. + + M. Delete any section Entitled “Endorsements”. Such a section + may not be included in the Modified Version. + + N. Do not retitle any existing section to be Entitled + “Endorsements” or to conflict in title with any Invariant + Section. + + O. Preserve any Warranty Disclaimers. + + If the Modified Version includes new front-matter sections or + appendices that qualify as Secondary Sections and contain no + material copied from the Document, you may at your option designate + some or all of these sections as invariant. To do this, add their + titles to the list of Invariant Sections in the Modified Version’s + license notice. These titles must be distinct from any other + section titles. + + You may add a section Entitled “Endorsements”, provided it contains + nothing but endorsements of your Modified Version by various + parties—for example, statements of peer review or that the text has + been approved by an organization as the authoritative definition of + a standard. + + You may add a passage of up to five words as a Front-Cover Text, + and a passage of up to 25 words as a Back-Cover Text, to the end of + the list of Cover Texts in the Modified Version. Only one passage + of Front-Cover Text and one of Back-Cover Text may be added by (or + through arrangements made by) any one entity. If the Document + already includes a cover text for the same cover, previously added + by you or by arrangement made by the same entity you are acting on + behalf of, you may not add another; but you may replace the old + one, on explicit permission from the previous publisher that added + the old one. + + The author(s) and publisher(s) of the Document do not by this + License give permission to use their names for publicity for or to + assert or imply endorsement of any Modified Version. + + 5. COMBINING DOCUMENTS + + You may combine the Document with other documents released under + this License, under the terms defined in section 4 above for + modified versions, provided that you include in the combination all + of the Invariant Sections of all of the original documents, + unmodified, and list them all as Invariant Sections of your + combined work in its license notice, and that you preserve all + their Warranty Disclaimers. + + The combined work need only contain one copy of this License, and + multiple identical Invariant Sections may be replaced with a single + copy. If there are multiple Invariant Sections with the same name + but different contents, make the title of each such section unique + by adding at the end of it, in parentheses, the name of the + original author or publisher of that section if known, or else a + unique number. Make the same adjustment to the section titles in + the list of Invariant Sections in the license notice of the + combined work. + + In the combination, you must combine any sections Entitled + “History” in the various original documents, forming one section + Entitled “History”; likewise combine any sections Entitled + “Acknowledgements”, and any sections Entitled “Dedications”. You + must delete all sections Entitled “Endorsements.” + + 6. COLLECTIONS OF DOCUMENTS + + You may make a collection consisting of the Document and other + documents released under this License, and replace the individual + copies of this License in the various documents with a single copy + that is included in the collection, provided that you follow the + rules of this License for verbatim copying of each of the documents + in all other respects. + + You may extract a single document from such a collection, and + distribute it individually under this License, provided you insert + a copy of this License into the extracted document, and follow this + License in all other respects regarding verbatim copying of that + document. + + 7. AGGREGATION WITH INDEPENDENT WORKS + + A compilation of the Document or its derivatives with other + separate and independent documents or works, in or on a volume of a + storage or distribution medium, is called an “aggregate” if the + copyright resulting from the compilation is not used to limit the + legal rights of the compilation’s users beyond what the individual + works permit. When the Document is included in an aggregate, this + License does not apply to the other works in the aggregate which + are not themselves derivative works of the Document. + + If the Cover Text requirement of section 3 is applicable to these + copies of the Document, then if the Document is less than one half + of the entire aggregate, the Document’s Cover Texts may be placed + on covers that bracket the Document within the aggregate, or the + electronic equivalent of covers if the Document is in electronic + form. Otherwise they must appear on printed covers that bracket + the whole aggregate. + + 8. TRANSLATION + + Translation is considered a kind of modification, so you may + distribute translations of the Document under the terms of section + 4. Replacing Invariant Sections with translations requires special + permission from their copyright holders, but you may include + translations of some or all Invariant Sections in addition to the + original versions of these Invariant Sections. You may include a + translation of this License, and all the license notices in the + Document, and any Warranty Disclaimers, provided that you also + include the original English version of this License and the + original versions of those notices and disclaimers. In case of a + disagreement between the translation and the original version of + this License or a notice or disclaimer, the original version will + prevail. + + If a section in the Document is Entitled “Acknowledgements”, + “Dedications”, or “History”, the requirement (section 4) to + Preserve its Title (section 1) will typically require changing the + actual title. + + 9. TERMINATION + + You may not copy, modify, sublicense, or distribute the Document + except as expressly provided under this License. Any attempt + otherwise to copy, modify, sublicense, or distribute it is void, + and will automatically terminate your rights under this License. + + However, if you cease all violation of this License, then your + license from a particular copyright holder is reinstated (a) + provisionally, unless and until the copyright holder explicitly and + finally terminates your license, and (b) permanently, if the + copyright holder fails to notify you of the violation by some + reasonable means prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is + reinstated permanently if the copyright holder notifies you of the + violation by some reasonable means, this is the first time you have + received notice of violation of this License (for any work) from + that copyright holder, and you cure the violation prior to 30 days + after your receipt of the notice. + + Termination of your rights under this section does not terminate + the licenses of parties who have received copies or rights from you + under this License. If your rights have been terminated and not + permanently reinstated, receipt of a copy of some or all of the + same material does not give you any rights to use it. + + 10. FUTURE REVISIONS OF THIS LICENSE + + The Free Software Foundation may publish new, revised versions of + the GNU Free Documentation License from time to time. Such new + versions will be similar in spirit to the present version, but may + differ in detail to address new problems or concerns. See + <http://www.gnu.org/copyleft/>. + + Each version of the License is given a distinguishing version + number. If the Document specifies that a particular numbered + version of this License “or any later version” applies to it, you + have the option of following the terms and conditions either of + that specified version or of any later version that has been + published (not as a draft) by the Free Software Foundation. If the + Document does not specify a version number of this License, you may + choose any version ever published (not as a draft) by the Free + Software Foundation. If the Document specifies that a proxy can + decide which future versions of this License can be used, that + proxy’s public statement of acceptance of a version permanently + authorizes you to choose that version for the Document. + + 11. RELICENSING + + “Massive Multiauthor Collaboration Site” (or “MMC Site”) means any + World Wide Web server that publishes copyrightable works and also + provides prominent facilities for anybody to edit those works. A + public wiki that anybody can edit is an example of such a server. + A “Massive Multiauthor Collaboration” (or “MMC”) contained in the + site means any set of copyrightable works thus published on the MMC + site. + + “CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0 + license published by Creative Commons Corporation, a not-for-profit + corporation with a principal place of business in San Francisco, + California, as well as future copyleft versions of that license + published by that same organization. + + “Incorporate” means to publish or republish a Document, in whole or + in part, as part of another Document. + + An MMC is “eligible for relicensing” if it is licensed under this + License, and if all works that were first published under this + License somewhere other than this MMC, and subsequently + incorporated in whole or in part into the MMC, (1) had no cover + texts or invariant sections, and (2) were thus incorporated prior + to November 1, 2008. + + The operator of an MMC Site may republish an MMC contained in the + site under CC-BY-SA on the same site at any time before August 1, + 2009, provided the MMC is eligible for relicensing. + +ADDENDUM: How to use this License for your documents +==================================================== + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and license +notices just after the title page: + + Copyright (C) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.3 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover + Texts. A copy of the license is included in the section entitled ``GNU + Free Documentation License''. + + If you have Invariant Sections, Front-Cover Texts and Back-Cover +Texts, replace the “with...Texts.” line with this: + + with the Invariant Sections being LIST THEIR TITLES, with + the Front-Cover Texts being LIST, and with the Back-Cover Texts + being LIST. + + If you have Invariant Sections without Cover Texts, or some other +combination of the three, merge those two alternatives to suit the +situation. + + If your document contains nontrivial examples of program code, we +recommend releasing these examples in parallel under your choice of free +software license, such as the GNU General Public License, to permit +their use in free software. + + +File: wget.info, Node: Concept Index, Prev: Copying this manual, Up: Top + +Concept Index +************* + + +* Menu: + +* #wget: Internet Relay Chat.

It supports @sc{http}, @sc{https}, and @sc{ftp} protocols, as +well as retrieval through @sc{http} proxies. + +@c man end +This chapter is a partial overview of Wget's features. + +@itemize @bullet +@item +@c man begin DESCRIPTION +Wget is non-interactive, meaning that it can work in the background, +while the user is not logged on. This allows you to start a retrieval +and disconnect from the system, letting Wget finish the work. By +contrast, most of the Web browsers require constant user's presence, +which can be a great hindrance when transferring a lot of data. +@c man end + +@item +@ignore +@c man begin DESCRIPTION + +@c man end +@end ignore +@c man begin DESCRIPTION +Wget can follow links in @sc{html}, @sc{xhtml}, and @sc{css} pages, to +create local versions of remote web sites, fully recreating the +directory structure of the original site. This is sometimes referred to +as ``recursive downloading.'' While doing that, Wget respects the Robot +Exclusion Standard (@file{/robots.txt}). Wget can be instructed to +convert the links in downloaded files to point at the local files, for +offline viewing. +@c man end + +@item +File name wildcard matching and recursive mirroring of directories are +available when retrieving via @sc{ftp}. Wget can read the time-stamp +information given by both @sc{http} and @sc{ftp} servers, and store it +locally. Thus Wget can see if the remote file has changed since last +retrieval, and automatically retrieve the new version if it has. This +makes Wget suitable for mirroring of @sc{ftp} sites, as well as home +pages. + +@item +@ignore +@c man begin DESCRIPTION + +@c man end +@end ignore +@c man begin DESCRIPTION +Wget has been designed for robustness over slow or unstable network +connections; if a download fails due to a network problem, it will +keep retrying until the whole file has been retrieved. If the server +supports regetting, it will instruct the server to continue the +download from where it left off. +@c man end + +@item +Wget supports proxy servers, which can lighten the network load, speed +up retrieval and provide access behind firewalls. Wget uses the passive +@sc{ftp} downloading by default, active @sc{ftp} being an option. + +@item +Wget supports IP version 6, the next generation of IP. IPv6 is +autodetected at compile-time, and can be disabled at either build or +run time. Binaries built with IPv6 support work well in both +IPv4-only and dual family environments. + +@item +Built-in features offer mechanisms to tune which links you wish to follow +(@pxref{Following Links}). + +@item +The progress of individual downloads is traced using a progress gauge. +Interactive downloads are tracked using a ``thermometer''-style gauge, +whereas non-interactive ones are traced with dots, each dot +representing a fixed amount of data received (1KB by default). Either +gauge can be customized to your preferences. + +@item +Most of the features are fully configurable, either through command line +options, or via the initialization file @file{.wgetrc} (@pxref{Startup +File}). Wget allows you to define @dfn{global} startup files +(@file{/usr/local/etc/wgetrc} by default) for site settings. You can also +specify the location of a startup file with the --config option. +To disable the reading of config files, use --no-config. +If both --config and --no-config are given, --no-config is ignored. + + +@ignore +@c man begin FILES +@table @samp +@item /usr/local/etc/wgetrc +Default location of the @dfn{global} startup file. + +@item .wgetrc +User startup file. +@end table +@c man end +@end ignore + +@item +Finally, GNU Wget is free software. This means that everyone may use +it, redistribute it and/or modify it under the terms of the GNU General +Public License, as published by the Free Software Foundation (see the +file @file{COPYING} that came with GNU Wget, for details). +@end itemize + +@node Invoking, Recursive Download, Overview, Top +@chapter Invoking +@cindex invoking +@cindex command line +@cindex arguments +@cindex nohup + +By default, Wget is very simple to invoke. The basic syntax is: + +@example +@c man begin SYNOPSIS +wget [@var{option}]@dots{} [@var{URL}]@dots{} +@c man end +@end example + +Wget will simply download all the @sc{url}s specified on the command +line. @var{URL} is a @dfn{Uniform Resource Locator}, as defined below. + +However, you may wish to change some of the default parameters of +Wget. You can do it two ways: permanently, adding the appropriate +command to @file{.wgetrc} (@pxref{Startup File}), or specifying it on +the command line. + +@menu +* URL Format:: +* Option Syntax:: +* Basic Startup Options:: +* Logging and Input File Options:: +* Download Options:: +* Directory Options:: +* HTTP Options:: +* HTTPS (SSL/TLS) Options:: +* FTP Options:: +* Recursive Retrieval Options:: +* Recursive Accept/Reject Options:: +* Exit Status:: +@end menu + +@node URL Format, Option Syntax, Invoking, Invoking +@section URL Format +@cindex URL +@cindex URL syntax + +@dfn{URL} is an acronym for Uniform Resource Locator. A uniform +resource locator is a compact string representation for a resource +available via the Internet. Wget recognizes the @sc{url} syntax as per +@sc{rfc1738}. This is the most widely used form (square brackets denote +optional parts): + +@example +http://host[:port]/directory/file +ftp://host[:port]/directory/file +@end example + +You can also encode your username and password within a @sc{url}: + +@example +ftp://user:password@@host/path +http://user:password@@host/path +@end example + +Either @var{user} or @var{password}, or both, may be left out. If you +leave out either the @sc{http} username or password, no authentication +will be sent. If you leave out the @sc{ftp} username, @samp{anonymous} +will be used. If you leave out the @sc{ftp} password, your email +address will be supplied as a default password.@footnote{If you have a +@file{.netrc} file in your home directory, password will also be +searched for there.} + +@strong{Important Note}: if you specify a password-containing @sc{url} +on the command line, the username and password will be plainly visible +to all users on the system, by way of @code{ps}. On multi-user systems, +this is a big security risk. To work around it, use @code{wget -i -} +and feed the @sc{url}s to Wget's standard input, each on a separate +line, terminated by @kbd{C-d}. + +You can encode unsafe characters in a @sc{url} as @samp{%xy}, @code{xy} +being the hexadecimal representation of the character's @sc{ascii} +value. Some common unsafe characters include @samp{%} (quoted as +@samp{%25}), @samp{:} (quoted as @samp{%3A}), and @samp{@@} (quoted as +@samp{%40}). Refer to @sc{rfc1738} for a comprehensive list of unsafe +characters. + +Wget also supports the @code{type} feature for @sc{ftp} @sc{url}s. By +default, @sc{ftp} documents are retrieved in the binary mode (type +@samp{i}), which means that they are downloaded unchanged. Another +useful mode is the @samp{a} (@dfn{ASCII}) mode, which converts the line +delimiters between the different operating systems, and is thus useful +for text files. Here is an example: + +@example +ftp://host/directory/file;type=a +@end example + +Two alternative variants of @sc{url} specification are also supported, +because of historical (hysterical?) reasons and their widespreaded use. + +@sc{ftp}-only syntax (supported by @code{NcFTP}): +@example +host:/dir/file +@end example + +@sc{http}-only syntax (introduced by @code{Netscape}): +@example +host[:port]/dir/file +@end example + +These two alternative forms are deprecated, and may cease being +supported in the future. + +If you do not understand the difference between these notations, or do +not know which one to use, just use the plain ordinary format you use +with your favorite browser, like @code{Lynx} or @code{Netscape}. + +@c man begin OPTIONS + +@node Option Syntax, Basic Startup Options, URL Format, Invoking +@section Option Syntax +@cindex option syntax +@cindex syntax of options + +Since Wget uses GNU getopt to process command-line arguments, every +option has a long form along with the short one. Long options are +more convenient to remember, but take time to type. You may freely +mix different option styles, or specify options after the command-line +arguments. Thus you may write: + +@example +wget -r --tries=10 http://fly.srk.fer.hr/ -o log +@end example + +The space between the option accepting an argument and the argument may +be omitted. Instead of @samp{-o log} you can write @samp{-olog}. + +You may put several options that do not require arguments together, +like: + +@example +wget -drc @var{URL} +@end example + +This is completely equivalent to: + +@example +wget -d -r -c @var{URL} +@end example + +Since the options can be specified after the arguments, you may +terminate them with @samp{--}. So the following will try to download +@sc{url} @samp{-x}, reporting failure to @file{log}: + +@example +wget -o log -- -x +@end example + +The options that accept comma-separated lists all respect the convention +that specifying an empty list clears its value. This can be useful to +clear the @file{.wgetrc} settings. For instance, if your @file{.wgetrc} +sets @code{exclude_directories} to @file{/cgi-bin}, the following +example will first reset it, and then set it to exclude @file{/~nobody} +and @file{/~somebody}. You can also clear the lists in @file{.wgetrc} +(@pxref{Wgetrc Syntax}). + +@example +wget -X "" -X /~nobody,/~somebody +@end example + +Most options that do not accept arguments are @dfn{boolean} options, +so named because their state can be captured with a yes-or-no +(``boolean'') variable. For example, @samp{--follow-ftp} tells Wget +to follow FTP links from HTML files and, on the other hand, +@samp{--no-glob} tells it not to perform file globbing on FTP URLs. A +boolean option is either @dfn{affirmative} or @dfn{negative} +(beginning with @samp{--no}). All such options share several +properties. + +Unless stated otherwise, it is assumed that the default behavior is +the opposite of what the option accomplishes. For example, the +documented existence of @samp{--follow-ftp} assumes that the default +is to @emph{not} follow FTP links from HTML pages. + +Affirmative options can be negated by prepending the @samp{--no-} to +the option name; negative options can be negated by omitting the +@samp{--no-} prefix. This might seem superfluous---if the default for +an affirmative option is to not do something, then why provide a way +to explicitly turn it off? But the startup file may in fact change +the default. For instance, using @code{follow_ftp = on} in +@file{.wgetrc} makes Wget @emph{follow} FTP links by default, and +using @samp{--no-follow-ftp} is the only way to restore the factory +default from the command line. + +@node Basic Startup Options, Logging and Input File Options, Option Syntax, Invoking +@section Basic Startup Options + +@table @samp +@item -V +@itemx --version +Display the version of Wget. + +@item -h +@itemx --help +Print a help message describing all of Wget's command-line options. + +@item -b +@itemx --background +Go to background immediately after startup.

(Use @samp{./-} to print to a file +literally named @samp{-}.) + +Use of @samp{-O} is @emph{not} intended to mean simply ``use the name +@var{file} instead of the one in the URL;'' rather, it is +analogous to shell redirection: +@samp{wget -O file http://foo} is intended to work like +@samp{wget -O - http://foo > file}; @file{file} will be truncated +immediately, and @emph{all} downloaded content will be written there. + +For this reason, @samp{-N} (for timestamp-checking) is not supported +in combination with @samp{-O}: since @var{file} is always newly +created, it will always have a very new timestamp. A warning will be +issued if this combination is used. + +Similarly, using @samp{-r} or @samp{-p} with @samp{-O} may not work as +you expect: Wget won't just download the first file to @var{file} and +then download the rest to their normal names: @emph{all} downloaded +content will be placed in @var{file}. This was disabled in version +1.11, but has been reinstated (with a warning) in 1.11.2, as there are +some cases where this behavior can actually have some use. + +A combination with @samp{-nc} is only accepted if the given output +file does not exist. + +Note that a combination with @samp{-k} is only permitted when +downloading a single document, as in that case it will just convert +all relative URIs to external ones; @samp{-k} makes no sense for +multiple URIs when they're all being downloaded to a single file; +@samp{-k} can be used only when the output is a regular file. + +@cindex clobbering, file +@cindex downloading multiple times +@cindex no-clobber +@item -nc +@itemx --no-clobber +If a file is downloaded more than once in the same directory, Wget's +behavior depends on a few options, including @samp{-nc}. In certain +cases, the local file will be @dfn{clobbered}, or overwritten, upon +repeated download. In other cases it will be preserved. + +When running Wget without @samp{-N}, @samp{-nc}, @samp{-r}, or +@samp{-p}, downloading the same file in the same directory will result +in the original copy of @var{file} being preserved and the second copy +being named @samp{@var{file}.1}. If that file is downloaded yet +again, the third copy will be named @samp{@var{file}.2}, and so on. +(This is also the behavior with @samp{-nd}, even if @samp{-r} or +@samp{-p} are in effect.) When @samp{-nc} is specified, this behavior +is suppressed, and Wget will refuse to download newer copies of +@samp{@var{file}}. Therefore, ``@code{no-clobber}'' is actually a +misnomer in this mode---it's not clobbering that's prevented (as the +numeric suffixes were already preventing clobbering), but rather the +multiple version saving that's prevented. + +When running Wget with @samp{-r} or @samp{-p}, but without @samp{-N}, +@samp{-nd}, or @samp{-nc}, re-downloading a file will result in the +new copy simply overwriting the old. Adding @samp{-nc} will prevent +this behavior, instead causing the original version to be preserved +and any newer copies on the server to be ignored. + +When running Wget with @samp{-N}, with or without @samp{-r} or +@samp{-p}, the decision as to whether or not to download a newer copy +of a file depends on the local and remote timestamp and size of the +file (@pxref{Time-Stamping}). @samp{-nc} may not be specified at the +same time as @samp{-N}. + +A combination with @samp{-O}/@samp{--output-document} is only accepted +if the given output file does not exist. + +Note that when @samp{-nc} is specified, files with the suffixes +@samp{.html} or @samp{.htm} will be loaded from the local disk and +parsed as if they had been retrieved from the Web. + +@cindex backing up files +@item --backups=@var{backups} +Before (over)writing a file, back up an existing file by adding a +@samp{.1} suffix (@samp{_1} on VMS) to the file name.

This is useful when you +want to finish up a download started by a previous instance of Wget, or +by another program. For instance: + +@example +wget -c ftp://sunsite.doc.ic.ac.uk/ls-lR.Z +@end example + +If there is a file named @file{ls-lR.Z} in the current directory, Wget +will assume that it is the first portion of the remote file, and will +ask the server to continue the retrieval from an offset equal to the +length of the local file. + +Note that you don't need to specify this option if you just want the +current invocation of Wget to retry downloading a file should the +connection be lost midway through. This is the default behavior. +@samp{-c} only affects resumption of downloads started @emph{prior} to +this invocation of Wget, and whose local files are still sitting around. + +Without @samp{-c}, the previous example would just download the remote +file to @file{ls-lR.Z.1}, leaving the truncated @file{ls-lR.Z} file +alone. + +If you use @samp{-c} on a non-empty file, and the server does not support +continued downloading, Wget will restart the download from scratch and overwrite +the existing file entirely. + +Beginning with Wget 1.7, if you use @samp{-c} on a file which is of +equal size as the one on the server, Wget will refuse to download the +file and print an explanatory message. The same happens when the file +is smaller on the server than locally (presumably because it was changed +on the server since your last download attempt)---because ``continuing'' +is not meaningful, no download occurs. + +On the other side of the coin, while using @samp{-c}, any file that's +bigger on the server than locally will be considered an incomplete +download and only @code{(length(remote) - length(local))} bytes will be +downloaded and tacked onto the end of the local file. This behavior can +be desirable in certain cases---for instance, you can use @samp{wget -c} +to download just the new portion that's been appended to a data +collection or log file. + +However, if the file is bigger on the server because it's been +@emph{changed}, as opposed to just @emph{appended} to, you'll end up +with a garbled file. Wget has no way of verifying that the local file +is really a valid prefix of the remote file. You need to be especially +careful of this when using @samp{-c} in conjunction with @samp{-r}, +since every file will be considered as an "incomplete download" candidate. + +Another instance where you'll get a garbled file if you try to use +@samp{-c} is if you have a lame @sc{http} proxy that inserts a +``transfer interrupted'' string into the local file. In the future a +``rollback'' option may be added to deal with this case. + +Note that @samp{-c} only works with @sc{ftp} servers and with @sc{http} +servers that support the @code{Range} header. + +@cindex offset +@cindex continue retrieval +@cindex incomplete downloads +@cindex resume download +@cindex start position +@item --start-pos=@var{OFFSET} +Start downloading at zero-based position @var{OFFSET}.

When +@samp{--start-pos} and @samp{--continue} are both specified, wget will emit a +warning then proceed as if @samp{--continue} was absent. + +Server support for continued download is required, otherwise @samp{--start-pos} +cannot help. See @samp{-c} for details. + +@cindex progress indicator +@cindex dot style +@item --progress=@var{type} +Select the type of the progress indicator you wish to use. Legal +indicators are ``dot'' and ``bar''. + +The ``bar'' indicator is used by default. It draws an @sc{ascii} progress +bar graphics (a.k.a ``thermometer'' display) indicating the status of +retrieval. If the output is not a TTY, the ``dot'' bar will be used by +default. + +Use @samp{--progress=dot} to switch to the ``dot'' display. It traces +the retrieval by printing dots on the screen, each dot representing a +fixed amount of downloaded data. + +The progress @var{type} can also take one or more parameters. The parameters +vary based on the @var{type} selected. Parameters to @var{type} are passed by +appending them to the type sperated by a colon (:) like this: +@samp{--progress=@var{type}:@var{parameter1}:@var{parameter2}}. + +When using the dotted retrieval, you may set the @dfn{style} by +specifying the type as @samp{dot:@var{style}}. Different styles assign +different meaning to one dot. With the @code{default} style each dot +represents 1K, there are ten dots in a cluster and 50 dots in a line. +The @code{binary} style has a more ``computer''-like orientation---8K +dots, 16-dots clusters and 48 dots per line (which makes for 384K +lines). The @code{mega} style is suitable for downloading large +files---each dot represents 64K retrieved, there are eight dots in a +cluster, and 48 dots on each line (so each line contains 3M). +If @code{mega} is not enough then you can use the @code{giga} +style---each dot represents 1M retrieved, there are eight dots in a +cluster, and 32 dots on each line (so each line contains 32M). + +With @samp{--progress=bar}, there are currently two possible parameters, +@var{force} and @var{noscroll}. + +When the output is not a TTY, the progress bar always falls back to ``dot'', +even if @samp{--progress=bar} was passed to Wget during invocation. This +behaviour can be overridden and the ``bar'' output forced by using the ``force'' +parameter as @samp{--progress=bar:force}. + +By default, the @samp{bar} style progress bar scroll the name of the file from +left to right for the file being downloaded if the filename exceeds the maximum +length allotted for its display. In certain cases, such as with +@samp{--progress=bar:force}, one may not want the scrolling filename in the +progress bar. By passing the ``noscroll'' parameter, Wget can be forced to +display as much of the filename as possible without scrolling through it. + +Note that you can set the default style using the @code{progress} +command in @file{.wgetrc}. That setting may be overridden from the +command line. For example, to force the bar output without scrolling, +use @samp{--progress=bar:force:noscroll}. + +@item --show-progress +Force wget to display the progress bar in any verbosity. + +By default, wget only displays the progress bar in verbose mode. One may +however, want wget to display the progress bar on screen in conjunction with +any other verbosity modes like @samp{--no-verbose} or @samp{--quiet}. This +is often a desired a property when invoking wget to download several small/large +files. In such a case, wget could simply be invoked with this parameter to get +a much cleaner output on the screen. + +This option will also force the progress bar to be printed to @file{stderr} when +used alongside the @samp{--output-file} option. + +@item -N +@itemx --timestamping +Turn on time-stamping. @xref{Time-Stamping}, for details. + +@item --no-if-modified-since +Do not send If-Modified-Since header in @samp{-N} mode. Send preliminary HEAD +request instead. This has only effect in @samp{-N} mode. + +@item --no-use-server-timestamps +Don't set the local file's timestamp by the one on the server. + +By default, when a file is downloaded, its timestamps are set to +match those from the remote file. This allows the use of +@samp{--timestamping} on subsequent invocations of wget. However, it +is sometimes useful to base the local file's timestamp on when it was +actually downloaded; for that purpose, the +@samp{--no-use-server-timestamps} option has been provided. + +@cindex server response, print +@item -S +@itemx --server-response +Print the headers sent by @sc{http} servers and responses sent by +@sc{ftp} servers. + +@cindex Wget as spider +@cindex spider +@item --spider +When invoked with this option, Wget will behave as a Web @dfn{spider}, +which means that it will not download the pages, just check that they +are there. For example, you can use Wget to check your bookmarks: + +@example +wget --spider --force-html -i bookmarks.html +@end example + +This feature needs much more work for Wget to get close to the +functionality of real web spiders. + +@cindex timeout +@item -T seconds +@itemx --timeout=@var{seconds} +Set the network timeout to @var{seconds} seconds. This is equivalent +to specifying @samp{--dns-timeout}, @samp{--connect-timeout}, and +@samp{--read-timeout}, all at the same time. + +When interacting with the network, Wget can check for timeout and +abort the operation if it takes too long. This prevents anomalies +like hanging reads and infinite connects. The only timeout enabled by +default is a 900-second read timeout. Setting a timeout to 0 disables +it altogether. Unless you know what you are doing, it is best not to +change the default timeout settings. + +All timeout-related options accept decimal values, as well as +subsecond values. For example, @samp{0.1} seconds is a legal (though +unwise) choice of timeout. Subsecond timeouts are useful for checking +server response times or for testing network latency. + +@cindex DNS timeout +@cindex timeout, DNS +@item --dns-timeout=@var{seconds} +Set the DNS lookup timeout to @var{seconds} seconds. DNS lookups that +don't complete within the specified time will fail. By default, there +is no timeout on DNS lookups, other than that implemented by system +libraries. + +@cindex connect timeout +@cindex timeout, connect +@item --connect-timeout=@var{seconds} +Set the connect timeout to @var{seconds} seconds. TCP connections that +take longer to establish will be aborted. By default, there is no +connect timeout, other than that implemented by system libraries. + +@cindex read timeout +@cindex timeout, read +@item --read-timeout=@var{seconds} +Set the read (and write) timeout to @var{seconds} seconds. The +``time'' of this timeout refers to @dfn{idle time}: if, at any point in +the download, no data is received for more than the specified number +of seconds, reading fails and the download is restarted. This option +does not directly affect the duration of the entire download. + +Of course, the remote server may choose to terminate the connection +sooner than this option requires. The default read timeout is 900 +seconds. + +@cindex bandwidth, limit +@cindex rate, limit +@cindex limit bandwidth +@item --limit-rate=@var{amount} +Limit the download speed to @var{amount} bytes per second. Amount may +be expressed in bytes, kilobytes with the @samp{k} suffix, or megabytes +with the @samp{m} suffix. For example, @samp{--limit-rate=20k} will +limit the retrieval rate to 20KB/s. This is useful when, for whatever +reason, you don't want Wget to consume the entire available bandwidth. + +This option allows the use of decimal numbers, usually in conjunction +with power suffixes; for example, @samp{--limit-rate=2.5k} is a legal +value. + +Note that Wget implements the limiting by sleeping the appropriate +amount of time after a network read that took less time than specified +by the rate. Eventually this strategy causes the TCP transfer to slow +down to approximately the specified rate. However, it may take some +time for this balance to be achieved, so don't be surprised if limiting +the rate doesn't work well with very small files. + +@cindex pause +@cindex wait +@item -w @var{seconds} +@itemx --wait=@var{seconds} +Wait the specified number of seconds between the retrievals. Use of +this option is recommended, as it lightens the server load by making the +requests less frequent. Instead of in seconds, the time can be +specified in minutes using the @code{m} suffix, in hours using @code{h} +suffix, or in days using @code{d} suffix. + +Specifying a large value for this option is useful if the network or the +destination host is down, so that Wget can wait long enough to +reasonably expect the network error to be fixed before the retry. The +waiting interval specified by this function is influenced by +@code{--random-wait}, which see. + +@cindex retries, waiting between +@cindex waiting between retries +@item --waitretry=@var{seconds} +If you don't want Wget to wait between @emph{every} retrieval, but only +between retries of failed downloads, you can use this option. Wget will +use @dfn{linear backoff}, waiting 1 second after the first failure on a +given file, then waiting 2 seconds after the second failure on that +file, up to the maximum number of @var{seconds} you specify. + +By default, Wget will assume a value of 10 seconds. + +@cindex wait, random +@cindex random wait +@item --random-wait +Some web sites may perform log analysis to identify retrieval programs +such as Wget by looking for statistically significant similarities in +the time between requests. This option causes the time between requests +to vary between 0.5 and 1.5 * @var{wait} seconds, where @var{wait} was +specified using the @samp{--wait} option, in order to mask Wget's +presence from such analysis. + +A 2001 article in a publication devoted to development on a popular +consumer platform provided code to perform this analysis on the fly. +Its author suggested blocking at the class C address level to ensure +automated retrieval programs were blocked despite changing DHCP-supplied +addresses. + +The @samp{--random-wait} option was inspired by this ill-advised +recommendation to block many unrelated users from a web site due to the +actions of one. + +@cindex proxy +@item --no-proxy +Don't use proxies, even if the appropriate @code{*_proxy} environment +variable is defined. + +@c man end +@xref{Proxies}, for more information about the use of proxies with +Wget. +@c man begin OPTIONS + +@cindex quota +@item -Q @var{quota} +@itemx --quota=@var{quota} +Specify download quota for automatic retrievals. The value can be +specified in bytes (default), kilobytes (with @samp{k} suffix), or +megabytes (with @samp{m} suffix). + +Note that quota will never affect downloading a single file. So if you +specify @samp{wget -Q10k https://example.com/ls-lR.gz}, all of the +@file{ls-lR.gz} will be downloaded. The same goes even when several +@sc{url}s are specified on the command-line. The quota is checked only +at the end of each downloaded file, so it will never result in a partially +downloaded file. Thus you may safely type @samp{wget -Q2m -i sites}---download +will be aborted after the file that exhausts the quota is completely +downloaded. + +Setting quota to 0 or to @samp{inf} unlimits the download quota. + +@cindex DNS cache +@cindex caching of DNS lookups +@item --no-dns-cache +Turn off caching of DNS lookups. Normally, Wget remembers the IP +addresses it looked up from DNS so it doesn't have to repeatedly +contact the DNS server for the same (typically small) set of hosts it +retrieves from. This cache exists in memory only; a new Wget run will +contact DNS again. + +However, it has been reported that in some situations it is not +desirable to cache host names, even for the duration of a +short-running application like Wget. With this option Wget issues a +new DNS lookup (more precisely, a new call to @code{gethostbyname} or +@code{getaddrinfo}) each time it makes a new connection. Please note +that this option will @emph{not} affect caching that might be +performed by the resolving library or by an external caching layer, +such as NSCD. + +If you don't understand exactly what this option does, you probably +won't need it. + +@cindex file names, restrict +@cindex Windows file names +@item --restrict-file-names=@var{modes} +Change which characters found in remote URLs must be escaped during +generation of local filenames. Characters that are @dfn{restricted} +by this option are escaped, i.e. replaced with @samp{%HH}, where +@samp{HH} is the hexadecimal number that corresponds to the restricted +character. This option may also be used to force all alphabetical +cases to be either lower- or uppercase. + +By default, Wget escapes the characters that are not valid or safe as +part of file names on your operating system, as well as control +characters that are typically unprintable. This option is useful for +changing these defaults, perhaps because you are downloading to a +non-native partition, or because you want to disable escaping of the +control characters, or you want to further restrict characters to only +those in the @sc{ascii} range of values. + +The @var{modes} are a comma-separated set of text values. The +acceptable values are @samp{unix}, @samp{windows}, @samp{nocontrol}, +@samp{ascii}, @samp{lowercase}, and @samp{uppercase}. The values +@samp{unix} and @samp{windows} are mutually exclusive (one will +override the other), as are @samp{lowercase} and +@samp{uppercase}. Those last are special cases, as they do not change +the set of characters that would be escaped, but rather force local +file paths to be converted either to lower- or uppercase. + +When ``unix'' is specified, Wget escapes the character @samp{/} and +the control characters in the ranges 0--31 and 128--159. This is the +default on Unix-like operating systems. + +When ``windows'' is given, Wget escapes the characters @samp{\}, +@samp{|}, @samp{/}, @samp{:}, @samp{?}, @samp{"}, @samp{*}, @samp{<}, +@samp{>}, and the control characters in the ranges 0--31 and 128--159. +In addition to this, Wget in Windows mode uses @samp{+} instead of +@samp{:} to separate host and port in local file names, and uses +@samp{@@} instead of @samp{?} to separate the query portion of the file +name from the rest. Therefore, a URL that would be saved as +@samp{www.xemacs.org:4300/search.pl?input=blah} in Unix mode would be +saved as @samp{www.xemacs.org+4300/search.pl@@input=blah} in Windows +mode. This mode is the default on Windows. + +If you specify @samp{nocontrol}, then the escaping of the control +characters is also switched off. This option may make sense +when you are downloading URLs whose names contain UTF-8 characters, on +a system which can save and display filenames in UTF-8 (some possible +byte values used in UTF-8 byte sequences fall in the range of values +designated by Wget as ``controls''). + +The @samp{ascii} mode is used to specify that any bytes whose values +are outside the range of @sc{ascii} characters (that is, greater than +127) shall be escaped. This can be useful when saving filenames +whose encoding does not match the one used locally. + +@cindex IPv6 +@item -4 +@itemx --inet4-only +@itemx -6 +@itemx --inet6-only +Force connecting to IPv4 or IPv6 addresses. With @samp{--inet4-only} +or @samp{-4}, Wget will only connect to IPv4 hosts, ignoring AAAA +records in DNS, and refusing to connect to IPv6 addresses specified in +URLs. Conversely, with @samp{--inet6-only} or @samp{-6}, Wget will +only connect to IPv6 hosts and ignore A records and IPv4 addresses. + +Neither options should be needed normally. By default, an IPv6-aware +Wget will use the address family specified by the host's DNS record. +If the DNS responds with both IPv4 and IPv6 addresses, Wget will try +them in sequence until it finds one it can connect to. (Also see +@code{--prefer-family} option described below.) + +These options can be used to deliberately force the use of IPv4 or +IPv6 address families on dual family systems, usually to aid debugging +or to deal with broken network configuration. Only one of +@samp{--inet6-only} and @samp{--inet4-only} may be specified at the +same time. Neither option is available in Wget compiled without IPv6 +support. + +@item --prefer-family=none/IPv4/IPv6 +When given a choice of several addresses, connect to the addresses +with specified address family first. The address order returned by +DNS is used without change by default. + +This avoids spurious errors and connect attempts when accessing hosts +that resolve to both IPv6 and IPv4 addresses from IPv4 networks. For +example, @samp{www.kame.net} resolves to +@samp{2001:200:0:8002:203:47ff:fea5:3085} and to +@samp{203.178.141.194}. When the preferred family is @code{IPv4}, the +IPv4 address is used first; when the preferred family is @code{IPv6}, +the IPv6 address is used first; if the specified value is @code{none}, +the address order returned by DNS is used without change. + +Unlike @samp{-4} and @samp{-6}, this option doesn't inhibit access to +any address family, it only changes the @emph{order} in which the +addresses are accessed. Also note that the reordering performed by +this option is @dfn{stable}---it doesn't affect order of addresses of +the same family. That is, the relative order of all IPv4 addresses +and of all IPv6 addresses remains intact in all cases. + +@item --retry-connrefused +Consider ``connection refused'' a transient error and try again. +Normally Wget gives up on a URL when it is unable to connect to the +site because failure to connect is taken as a sign that the server is +not running at all and that retries would not help.

That setting may be overridden from the +command line. + +@cindex remote encoding +@item --remote-encoding=@var{encoding} + +Force Wget to use @var{encoding} as the default remote server encoding. +That affects how Wget converts URIs found in files from remote encoding +to @sc{utf-8} during a recursive fetch.

E.g. @samp{wget -x +http://fly.srk.fer.hr/robots.txt} will save the downloaded file to +@file{fly.srk.fer.hr/robots.txt}. + +@item -nH +@itemx --no-host-directories +Disable generation of host-prefixed directories. By default, invoking +Wget with @samp{-r http://fly.srk.fer.hr/} will create a structure of +directories beginning with @file{fly.srk.fer.hr/}. This option disables +such behavior. + +@item --protocol-directories +Use the protocol name as a directory component of local file names. For +example, with this option, @samp{wget -r http://@var{host}} will save to +@samp{http/@var{host}/...} rather than just to @samp{@var{host}/...}. + +@cindex cut directories +@item --cut-dirs=@var{number} +Ignore @var{number} directory components. This is useful for getting a +fine-grained control over the directory where recursive retrieval will +be saved. + +Take, for example, the directory at +@samp{ftp://ftp.xemacs.org/pub/xemacs/}.

While the @samp{-nH} option can +remove the @file{ftp.xemacs.org/} part, you are still stuck with +@file{pub/xemacs}. This is where @samp{--cut-dirs} comes in handy; it +makes Wget not ``see'' @var{number} remote directory components. Here +are several examples of how @samp{--cut-dirs} option works. + +@example +@group +No options -> ftp.xemacs.org/pub/xemacs/ +-nH -> pub/xemacs/ +-nH --cut-dirs=1 -> xemacs/ +-nH --cut-dirs=2 -> . + +--cut-dirs=1 -> ftp.xemacs.org/xemacs/ +... +@end group +@end example + +If you just want to get rid of the directory structure, this option is +similar to a combination of @samp{-nd} and @samp{-P}.

This is useful, for instance, when +you're mirroring a remote site that uses @samp{.asp} pages, but you want +the mirrored pages to be viewable on your stock Apache server. Another +good use for this is when you're downloading CGI-generated materials. A URL +like @samp{http://site.com/article.cgi?25} will be saved as +@file{article.cgi?25.html}. + +Note that filenames changed in this way will be re-downloaded every time +you re-mirror a site, because Wget can't tell that the local +@file{@var{X}.html} file corresponds to remote URL @samp{@var{X}} (since +it doesn't yet know that the URL produces output of type +@samp{text/html} or @samp{application/xhtml+xml}. + +As of version 1.12, Wget will also ensure that any downloaded files of +type @samp{text/css} end in the suffix @samp{.css}, and the option was +renamed from @samp{--html-extension}, to better reflect its new +behavior.

Either method reveals your password to anyone who +bothers to run @code{ps}. To prevent the passwords from being seen, +use the @samp{--use-askpass} or store them in @file{.wgetrc} or @file{.netrc}, +and make sure to protect those files from other users with @code{chmod}.

Normally, Wget +asks the server to keep the connection open so that, when you download +more than one document from the same server, they get transferred over +the same TCP connection. This saves time and at the same time reduces +the load on the server. + +This option is useful when, for some reason, persistent (keep-alive) +connections don't work for you, for example due to a server bug or due +to the inability of server-side scripts to cope with the connections. + +@cindex proxy +@cindex cache +@item --no-cache +Disable server-side cache. In this case, Wget will send the remote +server appropriate directives (@samp{Cache-Control: no-cache} and +@samp{Pragma: no-cache}) to get the file from the remote service, +rather than returning the cached version. This is especially useful +for retrieving and flushing out-of-date documents on proxy servers. + +Caching is allowed by default. + +@cindex cookies +@item --no-cookies +Disable the use of cookies. Cookies are a mechanism for maintaining +server-side state. The server sends the client a cookie using the +@code{Set-Cookie} header, and the client responds with the same cookie +upon further requests. Since cookies allow the server owners to keep +track of visitors and for sites to exchange this information, some +consider them a breach of privacy. The default is to use cookies; +however, @emph{storing} cookies is not on by default. + +@cindex loading cookies +@cindex cookies, loading +@item --load-cookies @var{file} +Load cookies from @var{file} before the first HTTP retrieval. +@var{file} is a textual file in the format originally used by Netscape's +@file{cookies.txt} file. + +You will typically use this option when mirroring sites that require +that you be logged in to access some or all of their content. The login +process typically works by the web server issuing an @sc{http} cookie +upon receiving and verifying your credentials. The cookie is then +resent by the browser when accessing that part of the site, and so +proves your identity. + +Mirroring such a site requires Wget to send the same cookies your +browser sends when communicating with the site. This is achieved by +@samp{--load-cookies}---simply point Wget to the location of the +@file{cookies.txt} file, and it will send the same cookies your browser +would send in the same situation. Different browsers keep textual +cookie files in different locations: + +@table @asis +@item Netscape 4.x. +The cookies are in @file{~/.netscape/cookies.txt}. + +@item Mozilla and Netscape 6.x. +Mozilla's cookie file is also named @file{cookies.txt}, located +somewhere under @file{~/.mozilla}, in the directory of your profile. +The full path usually ends up looking somewhat like +@file{~/.mozilla/default/@var{some-weird-string}/cookies.txt}. + +@item Internet Explorer. +You can produce a cookie file Wget can use by using the File menu, +Import and Export, Export Cookies. This has been tested with Internet +Explorer 5; it is not guaranteed to work with earlier versions. + +@item Other browsers. +If you are using a different browser to create your cookies, +@samp{--load-cookies} will only work if you can locate or produce a +cookie file in the Netscape format that Wget expects. +@end table + +If you cannot use @samp{--load-cookies}, there might still be an +alternative. If your browser supports a ``cookie manager'', you can use +it to view the cookies used when accessing the site you're mirroring. +Write down the name and value of the cookie, and manually instruct Wget +to send those cookies, bypassing the ``official'' cookie support: + +@example +wget --no-cookies --header "Cookie: @var{name}=@var{value}" +@end example + +@cindex saving cookies +@cindex cookies, saving +@item --save-cookies @var{file} +Save cookies to @var{file} before exiting.

Session cookies are normally not saved because they are +meant to be kept in memory and forgotten when you exit the browser. +Saving them is useful on sites that require you to log in or to visit +the home page before you can access some pages. With this option, +multiple Wget runs are considered a single browser session as far as +the site is concerned. + +Since the cookie file format does not normally carry session cookies, +Wget marks them with an expiry timestamp of 0. Wget's +@samp{--load-cookies} recognizes those as session cookies, but it might +confuse other browsers. Also note that cookies so loaded will be +treated as other session cookies, which means that if you want +@samp{--save-cookies} to preserve them again, you must use +@samp{--keep-session-cookies} again. + +@cindex Content-Length, ignore +@cindex ignore length +@item --ignore-length +Unfortunately, some @sc{http} servers (@sc{cgi} programs, to be more +precise) send out bogus @code{Content-Length} headers, which makes Wget +go wild, as it thinks not all the document was retrieved. You can spot +this syndrome if Wget retries getting the same document again and again, +each time claiming that the (otherwise normal) connection has closed on +the very same byte. + +With this option, Wget will ignore the @code{Content-Length} header---as +if it never existed. + +@cindex header, add +@item --header=@var{header-line} +Send @var{header-line} along with the rest of the headers in each +@sc{http} request. The supplied header is sent as-is, which means it +must contain name and value separated by colon, and must not contain +newlines. + +You may define more than one additional header by specifying +@samp{--header} more than once. + +@example +@group +wget --header='Accept-Charset: iso-8859-2' \ + --header='Accept-Language: hr' \ + http://fly.srk.fer.hr/ +@end group +@end example + +Specification of an empty string as the header value will clear all +previous user-defined headers. + +As of Wget 1.10, this option can be used to override headers otherwise +generated automatically.

Legal values are +@samp{auto}, @samp{gzip} and @samp{none}. + +If @samp{auto} or @samp{gzip} are specified, Wget asks the server to +compress the file using the gzip compression format. If the server +compresses the file and responds with the @code{Content-Encoding} +header field set appropriately, the file will be decompressed +automatically. + +If @samp{none} is specified, wget will not ask the server to compress +the file and will not decompress any server responses. This is the default. + +Compression support is currently experimental. In case it is turned on, +please report any bugs to @code{bug-wget@@gnu.org}. + +@cindex redirect +@item --max-redirect=@var{number} +Specifies the maximum number of redirections to follow for a resource. +The default is 20, which is usually far more than necessary.

This enables distinguishing the +@sc{www} software, usually for statistical purposes or for tracing of +protocol violations. Wget normally identifies as +@samp{Wget/@var{version}}, @var{version} being the current version +number of Wget. + +However, some sites have been known to impose the policy of tailoring +the output according to the @code{User-Agent}-supplied information. +While this is not such a bad idea in theory, it has been abused by +servers denying information to clients other than (historically) +Netscape or, more frequently, Microsoft Internet Explorer. This +option allows you to change the @code{User-Agent} line issued by Wget. +Use of this option is discouraged, unless you really know what you are +doing. + +Specifying empty user agent with @samp{--user-agent=""} instructs Wget +not to send the @code{User-Agent} header in @sc{http} requests. + +@cindex POST +@item --post-data=@var{string} +@itemx --post-file=@var{file} +Use POST as the method for all HTTP requests and send the specified +data in the request body. @samp{--post-data} sends @var{string} as +data, whereas @samp{--post-file} sends the contents of @var{file}. +Other than that, they work in exactly the same way. In particular, +they @emph{both} expect content of the form @code{key1=value1&key2=value2}, +with percent-encoding for special characters; the only difference is +that one expects its content as a command-line parameter and the other +accepts its content from a file. In particular, @samp{--post-file} is +@emph{not} for transmitting files as form attachments: those must +appear as @code{key=value} data (with appropriate percent-coding) just +like everything else. Wget does not currently support +@code{multipart/form-data} for transmitting POST data; only +@code{application/x-www-form-urlencoded}. Only one of +@samp{--post-data} and @samp{--post-file} should be specified. + +Please note that wget does not require the content to be of the form +@code{key1=value1&key2=value2}, and neither does it test for it. Wget will +simply transmit whatever data is provided to it. Most servers however expect +the POST data to be in the above format when processing HTML Forms. + +When sending a POST request using the @samp{--post-file} option, Wget treats +the file as a binary file and will send every character in the POST request +without stripping trailing newline or formfeed characters. Any other control +characters in the text will also be sent as-is in the POST request. + +Please be aware that Wget needs to know the size of the POST data in +advance. Therefore the argument to @code{--post-file} must be a regular +file; specifying a FIFO or something like @file{/dev/stdin} won't work. +It's not quite clear how to work around this limitation inherent in +HTTP/1.0. Although HTTP/1.1 introduces @dfn{chunked} transfer that +doesn't require knowing the request length in advance, a client can't +use chunked unless it knows it's talking to an HTTP/1.1 server. And it +can't know that until it receives a response, which in turn requires the +request to have been completed -- a chicken-and-egg problem. + +Note: As of version 1.15 if Wget is redirected after the POST request is +completed, its behaviour will depend on the response code returned by the +server. In case of a 301 Moved Permanently, 302 Moved Temporarily or +307 Temporary Redirect, Wget will, in accordance with RFC2616, continue +to send a POST request. +In case a server wants the client to change the Request method upon +redirection, it should send a 303 See Other response code. + +This example shows how to log in to a server using POST and then proceed to +download the desired pages, presumably only accessible to authorized +users: + +@example +@group +# @r{Log in to the server. This can be done only once.} +wget --save-cookies cookies.txt \ + --post-data 'user=foo&password=bar' \ + http://example.com/auth.php + +# @r{Now grab the page or pages we care about.} +wget --load-cookies cookies.txt \ + -p http://example.com/interesting/article.php +@end group +@end example + +If the server is using session cookies to track user authentication, +the above will not work because @samp{--save-cookies} will not save +them (and neither will browsers) and the @file{cookies.txt} file will +be empty. In that case use @samp{--keep-session-cookies} along with +@samp{--save-cookies} to force saving of session cookies. + +@cindex Other HTTP Methods +@item --method=@var{HTTP-Method} +For the purpose of RESTful scripting, Wget allows sending of other HTTP Methods +without the need to explicitly set them using @samp{--header=Header-Line}. +Wget will use whatever string is passed to it after @samp{--method} as the HTTP +Method to the server. + +@item --body-data=@var{Data-String} +@itemx --body-file=@var{Data-File} +Must be set when additional data needs to be sent to the server along with the +Method specified using @samp{--method}. @samp{--body-data} sends @var{string} as +data, whereas @samp{--body-file} sends the contents of @var{file}. Other than that, +they work in exactly the same way. + +Currently, @samp{--body-file} is @emph{not} for transmitting files as a whole. +Wget does not currently support @code{multipart/form-data} for transmitting data; +only @code{application/x-www-form-urlencoded}. In the future, this may be changed +so that wget sends the @samp{--body-file} as a complete file instead of sending its +contents to the server. Please be aware that Wget needs to know the contents of +BODY Data in advance, and hence the argument to @samp{--body-file} should be a +regular file. See @samp{--post-file} for a more detailed explanation. +Only one of @samp{--body-data} and @samp{--body-file} should be specified. + +If Wget is redirected after the request is completed, Wget will +suspend the current method and send a GET request till the redirection +is completed. This is true for all redirection response codes except +307 Temporary Redirect which is used to explicitly specify that the +request method should @emph{not} change. Another exception is when +the method is set to @code{POST}, in which case the redirection rules +specified under @samp{--post-data} are followed. + +@cindex Content-Disposition +@item --content-disposition + +If this is set to on, experimental (not fully-functional) support for +@code{Content-Disposition} headers is enabled. This can currently result in +extra round-trips to the server for a @code{HEAD} request, and is known +to suffer from a few bugs, which is why it is not currently enabled by default. + +This option is useful for some file-downloading CGI programs that use +@code{Content-Disposition} headers to describe what the name of a +downloaded file should be. + +When combined with @samp{--metalink-over-http} and @samp{--trust-server-names}, +a @samp{Content-Type: application/metalink4+xml} file is named using the +@code{Content-Disposition} filename field, if available. + +@cindex Content On Error +@item --content-on-error + +If this is set to on, wget will not skip the content when the server responds +with a http status code that indicates error. + +@cindex Trust server names +@item --trust-server-names + +If this is set, on a redirect, the local file name will be based +on the redirection URL. By default the local file name is based on +the original URL. When doing recursive retrieving this can be helpful +because in many web sites redirected URLs correspond to an underlying +file structure, while link URLs do not. + +@cindex authentication +@item --auth-no-challenge + +If this option is given, Wget will send Basic HTTP authentication +information (plaintext username and password) for all requests, just +like Wget 1.10.2 and prior did by default. + +Use of this option is not recommended, and is intended only to support +some few obscure servers, which never send HTTP authentication +challenges, but accept unsolicited auth info, say, in addition to +form-based authentication. + +@item --retry-on-host-error +Consider host errors, such as ``Temporary failure in name resolution'', +as non-fatal, transient errors. + +@item --retry-on-http-error=@var{code[,code,...]} +Consider given HTTP response codes as non-fatal, transient errors. +Supply a comma-separated list of 3-digit HTTP response codes as +argument. Useful to work around special circumstances where retries +are required, but the server responds with an error code normally not +retried by Wget. Such errors might be 503 (Service Unavailable) and +429 (Too Many Requests). Retries enabled by this option are performed +subject to the normal retry timing and retry count limitations of +Wget. + +Using this option is intended to support special use cases only and is +generally not recommended, as it can force retries even in cases where +the server is actually trying to decrease its load. Please use wisely +and only if you know what you are doing. + +@end table + +@node HTTPS (SSL/TLS) Options, FTP Options, HTTP Options, Invoking +@section HTTPS (SSL/TLS) Options + +@cindex SSL +To support encrypted HTTP (HTTPS) downloads, Wget must be compiled +with an external SSL library.

If @samp{auto} is used, the SSL library is +given the liberty of choosing the appropriate protocol automatically, which is +achieved by sending a TLSv1 greeting. This is the default. + +Specifying @samp{SSLv2}, @samp{SSLv3}, @samp{TLSv1}, @samp{TLSv1_1}, +@samp{TLSv1_2} or @samp{TLSv1_3} forces the use of the corresponding +protocol. This is useful when talking to old and buggy SSL server +implementations that make it hard for the underlying SSL library to choose +the correct protocol version. Fortunately, such servers are quite rare. + +Specifying @samp{PFS} enforces the use of the so-called Perfect Forward +Security cipher suites. In short, PFS adds security by creating a one-time +key for each SSL connection. It has a bit more CPU impact on client and server. +We use known to be secure ciphers (e.g. no MD4) and the TLS protocol.

Typically this string sets the +cipher suites and other SSL/TLS options that the user wish should be used, in a +set order of preference (GnuTLS calls it 'priority string'). This string +will be fed verbatim to the SSL/TLS engine (OpenSSL or GnuTLS) and hence +its format and syntax is dependent on that. Wget will not process or manipulate it +in any way. Refer to the OpenSSL or GnuTLS documentation for more information. + +@cindex SSL certificate, check +@item --no-check-certificate +Don't check the server certificate against the available certificate +authorities. Also don't require the URL host name to match the common +name presented by the certificate. + +As of Wget 1.10, the default is to verify the server's certificate +against the recognized certificate authorities, breaking the SSL +handshake and aborting the download if the verification fails. +Although this provides more secure downloads, it does break +interoperability with some sites that worked with previous Wget +versions, particularly those using self-signed, expired, or otherwise +invalid certificates. This option forces an ``insecure'' mode of +operation that turns the certificate verification errors into warnings +and allows you to proceed. + +If you encounter ``certificate verification'' errors or ones saying +that ``common name doesn't match requested host name'', you can use +this option to bypass the verification and proceed with the download. +@emph{Only use this option if you are otherwise convinced of the +site's authenticity, or if you really don't care about the validity of +its certificate.} It is almost always a bad idea not to check the +certificates when transmitting confidential or important data. +For self-signed/internal certificates, you should download the certificate +and verify against that instead of forcing this insecure mode. +If you are really sure of not desiring any certificate verification, you +can specify --check-certificate=quiet to tell wget to not print any +warning about invalid certificates, albeit in most cases this is the +wrong thing to do. + +@cindex SSL certificate +@item --certificate=@var{file} +Use the client certificate stored in @var{file}. This is needed for +servers that are configured to require certificates from the clients +that connect to them. Normally a certificate is not required and this +switch is optional. + +@cindex SSL certificate type, specify +@item --certificate-type=@var{type} +Specify the type of the client certificate. Legal values are +@samp{PEM} (assumed by default) and @samp{DER}, also known as +@samp{ASN1}. + +@item --private-key=@var{file} +Read the private key from @var{file}. This allows you to provide the +private key in a file separate from the certificate. + +@item --private-key-type=@var{type} +Specify the type of the private key. Accepted values are @samp{PEM} +(the default) and @samp{DER}. + +@item --ca-certificate=@var{file} +Use @var{file} as the file with the bundle of certificate authorities +(``CA'') to verify the peers. The certificates must be in PEM format. + +Without this option Wget looks for CA certificates at the +system-specified locations, chosen at OpenSSL installation time. + +@cindex SSL certificate authority +@item --ca-directory=@var{directory} +Specifies directory containing CA certificates in PEM format. Each +file contains one CA certificate, and the file name is based on a hash +value derived from the certificate. This is achieved by processing a +certificate directory with the @code{c_rehash} utility supplied with +OpenSSL. Using @samp{--ca-directory} is more efficient than +@samp{--ca-certificate} when many certificates are installed because +it allows Wget to fetch certificates on demand. + +Without this option Wget looks for CA certificates at the +system-specified locations, chosen at OpenSSL installation time. + +@cindex SSL CRL, certificate revocation list +@item --crl-file=@var{file} +Specifies a CRL file in @var{file}. This is needed for certificates +that have been revocated by the CAs. + +@cindex SSL Public Key Pin +@item --pinnedpubkey=file/hashes +Tells wget to use the specified public key file (or hashes) to verify the peer. +This can be a path to a file which contains a single public key in PEM or DER +format, or any number of base64 encoded sha256 hashes preceded by ``sha256//'' +and separated by ``;'' + +When negotiating a TLS or SSL connection, the server sends a certificate +indicating its identity. A public key is extracted from this certificate and if +it does not exactly match the public key(s) provided to this option, wget will +abort the connection before sending or receiving any data. + +@cindex entropy, specifying source of +@cindex randomness, specifying source of +@item --random-file=@var{file} +[OpenSSL and LibreSSL only] +Use @var{file} as the source of random data for seeding the +pseudo-random number generator on systems without @file{/dev/urandom}. + +On such systems the SSL library needs an external source of randomness +to initialize. Randomness may be provided by EGD (see +@samp{--egd-file} below) or read from an external source specified by +the user. If this option is not specified, Wget looks for random data +in @code{$RANDFILE} or, if that is unset, in @file{$HOME/.rnd}. + +If you're getting the ``Could not seed OpenSSL PRNG; disabling SSL.'' +error, you should provide random data using some of the methods +described above. + +@cindex EGD +@item --egd-file=@var{file} +[OpenSSL only] +Use @var{file} as the EGD socket. EGD stands for @dfn{Entropy +Gathering Daemon}, a user-space program that collects data from +various unpredictable system sources and makes it available to other +programs that might need it. Encryption software, such as the SSL +library, needs sources of non-repeating randomness to seed the random +number generator used to produce cryptographically strong keys. + +OpenSSL allows the user to specify his own source of entropy using the +@code{RAND_FILE} environment variable. If this variable is unset, or +if the specified file does not produce enough randomness, OpenSSL will +read random data from EGD socket specified using this option. + +If this option is not specified (and the equivalent startup command is +not used), EGD is never contacted. EGD is not needed on modern Unix +systems that support @file{/dev/urandom}. + +@cindex HSTS +@item --no-hsts +Wget supports HSTS (HTTP Strict Transport Security, RFC 6797) by default. +Use @samp{--no-hsts} to make Wget act as a non-HSTS-compliant UA. As a +consequence, Wget would ignore all the @code{Strict-Transport-Security} +headers, and would not enforce any existing HSTS policy. + +@item --hsts-file=@var{file} +By default, Wget stores its HSTS database in @file{~/.wget-hsts}. +You can use @samp{--hsts-file} to override this. Wget will use +the supplied file as the HSTS database. Such file must conform to the +correct HSTS database format used by Wget. If Wget cannot parse the provided +file, the behaviour is unspecified. + +The Wget's HSTS database is a plain text file. Each line contains an HSTS entry +(ie. a site that has issued a @code{Strict-Transport-Security} header and that +therefore has specified a concrete HSTS policy to be applied). Lines starting with +a dash (@code{#}) are ignored by Wget. Please note that in spite of this convenient +human-readability hand-hacking the HSTS database is generally not a good idea. + +An HSTS entry line consists of several fields separated by one or more whitespace: + +@code{<hostname> SP [<port>] SP <include subdomains> SP <created> SP <max-age>} + +The @var{hostname} and @var{port} fields indicate the hostname and port to which +the given HSTS policy applies. The @var{port} field may be zero, and it will, in +most of the cases. That means that the port number will not be taken into account +when deciding whether such HSTS policy should be applied on a given request (only +the hostname will be evaluated). When @var{port} is different to zero, both the +target hostname and the port will be evaluated and the HSTS policy will only be applied +if both of them match. This feature has been included for testing/development purposes only. +The Wget testsuite (in @file{testenv/}) creates HSTS databases with explicit ports +with the purpose of ensuring Wget's correct behaviour. Applying HSTS policies to ports +other than the default ones is discouraged by RFC 6797 (see Appendix B "Differences +between HSTS Policy and Same-Origin Policy"). Thus, this functionality should not be used +in production environments and @var{port} will typically be zero. The last three fields +do what they are expected to. The field @var{include_subdomains} can either be @code{1} +or @code{0} and it signals whether the subdomains of the target domain should be +part of the given HSTS policy as well. The @var{created} and @var{max-age} fields +hold the timestamp values of when such entry was created (first seen by Wget) and the +HSTS-defined value 'max-age', which states how long should that HSTS policy remain active, +measured in seconds elapsed since the timestamp stored in @var{created}. Once that time +has passed, that HSTS policy will no longer be valid and will eventually be removed +from the database. + +If you supply your own HSTS database via @samp{--hsts-file}, be aware that Wget +may modify the provided file if any change occurs between the HSTS policies +requested by the remote servers and those in the file. When Wget exits, +it effectively updates the HSTS database by rewriting the database file with the new entries. + +If the supplied file does not exist, Wget will create one. This file will contain the new HSTS +entries. If no HSTS entries were generated (no @code{Strict-Transport-Security} headers +were sent by any of the servers) then no file will be created, not even an empty one. This +behaviour applies to the default database file (@file{~/.wget-hsts}) as well: it will not be +created until some server enforces an HSTS policy. + +Care is taken not to override possible changes made by other Wget processes at +the same time over the HSTS database. Before dumping the updated HSTS entries +on the file, Wget will re-read it and merge the changes. + +Using a custom HSTS database and/or modifying an existing one is discouraged. +For more information about the potential security threats arose from such practice, +see section 14 "Security Considerations" of RFC 6797, specially section 14.9 +"Creative Manipulation of HSTS Policy Store". +@end table + +@cindex WARC +@table @samp +@item --warc-file=@var{file} +Use @var{file} as the destination WARC file. + +@item --warc-header=@var{string} +Use @var{string} into as the warcinfo record. + +@item --warc-max-size=@var{size} +Set the maximum size of the WARC files to @var{size}. + +@item --warc-cdx +Write CDX index files. + +@item --warc-dedup=@var{file} +Do not store records listed in this CDX file. + +@item --no-warc-compression +Do not compress WARC files with GZIP. + +@item --no-warc-digests +Do not calculate SHA1 digests. + +@item --no-warc-keep-log +Do not store the log file in a WARC record. + +@item --warc-tempdir=@var{dir} +Specify the location for temporary files created by the WARC writer. +@end table + +@node FTP Options, Recursive Retrieval Options, HTTPS (SSL/TLS) Options, Invoking +@section FTP Options + +@table @samp +@cindex ftp user +@cindex ftp password +@cindex ftp authentication +@item --ftp-user=@var{user} +@itemx --ftp-password=@var{password} +Specify the username @var{user} and password @var{password} on an +@sc{ftp} server. Without this, or the corresponding startup option, +the password defaults to @samp{-wget@@}, normally used for anonymous +FTP. + +Another way to specify username and password is in the @sc{url} itself +(@pxref{URL Format}). Either method reveals your password to anyone who +bothers to run @code{ps}. To prevent the passwords from being seen, +store them in @file{.wgetrc} or @file{.netrc}, and make sure to protect +those files from other users with @code{chmod}. If the passwords are +really important, do not leave them lying in those files either---edit +the files and delete them after Wget has started the download. + +@iftex +@xref{Security Considerations}, for more information about security +issues with Wget. +@end iftex + +@cindex .listing files, removing +@item --no-remove-listing +Don't remove the temporary @file{.listing} files generated by @sc{ftp} +retrievals. Normally, these files contain the raw directory listings +received from @sc{ftp} servers. Not removing them can be useful for +debugging purposes, or when you want to be able to easily check on the +contents of remote server directories (e.g. to verify that a mirror +you're running is complete). + +Note that even though Wget writes to a known filename for this file, +this is not a security hole in the scenario of a user making +@file{.listing} a symbolic link to @file{/etc/passwd} or something and +asking @code{root} to run Wget in his or her directory. Depending on +the options used, either Wget will refuse to write to @file{.listing}, +making the globbing/recursion/time-stamping operation fail, or the +symbolic link will be deleted and replaced with the actual +@file{.listing} file, or the listing will be written to a +@file{.listing.@var{number}} file. + +Even though this situation isn't a problem, though, @code{root} should +never run Wget in a non-trusted user's directory. A user could do +something as simple as linking @file{index.html} to @file{/etc/passwd} +and asking @code{root} to run Wget with @samp{-N} or @samp{-r} so the file +will be overwritten. + +@cindex globbing, toggle +@item --no-glob +Turn off @sc{ftp} globbing. Globbing refers to the use of shell-like +special characters (@dfn{wildcards}), like @samp{*}, @samp{?}, @samp{[} +and @samp{]} to retrieve more than one file from the same directory at +once, like: + +@example +wget ftp://gnjilux.srk.fer.hr/*.msg +@end example + +By default, globbing will be turned on if the @sc{url} contains a +globbing character. This option may be used to turn globbing on or off +permanently. + +You may have to quote the @sc{url} to protect it from being expanded by +your shell. Globbing makes Wget look for a directory listing, which is +system-specific. This is why it currently works only with Unix @sc{ftp} +servers (and the ones emulating Unix @code{ls} output). + +@cindex passive ftp +@item --no-passive-ftp +Disable the use of the @dfn{passive} FTP transfer mode. Passive FTP +mandates that the client connect to the server to establish the data +connection rather than the other way around. + +If the machine is connected to the Internet directly, both passive and +active FTP should work equally well. Behind most firewall and NAT +configurations passive FTP has a better chance of working. However, +in some rare firewall configurations, active FTP actually works when +passive FTP doesn't. If you suspect this to be the case, use this +option, or set @code{passive_ftp=off} in your init file. + +@cindex file permissions +@item --preserve-permissions +Preserve remote file permissions instead of permissions set by umask. + +@cindex symbolic links, retrieving +@item --retr-symlinks +By default, when retrieving @sc{ftp} directories recursively and a symbolic link +is encountered, the symbolic link is traversed and the pointed-to files are +retrieved. Currently, Wget does not traverse symbolic links to directories to +download them recursively, though this feature may be added in the future. + +When @samp{--retr-symlinks=no} is specified, the linked-to file is not +downloaded. Instead, a matching symbolic link is created on the local +file system. The pointed-to file will not be retrieved unless this recursive +retrieval would have encountered it separately and downloaded it anyway. This +option poses a security risk where a malicious FTP Server may cause Wget to +write to files outside of the intended directories through a specially crafted +@sc{.listing} file. + +Note that when retrieving a file (not a directory) because it was +specified on the command-line, rather than because it was recursed to, +this option has no effect. Symbolic links are always traversed in this +case. +@end table + +@section FTPS Options + +@table @samp +@item --ftps-implicit +This option tells Wget to use FTPS implicitly. Implicit FTPS consists of initializing +SSL/TLS from the very beginning of the control connection. This option does not send +an @code{AUTH TLS} command: it assumes the server speaks FTPS and directly starts an +SSL/TLS connection. If the attempt is successful, the session continues just like +regular FTPS (@code{PBSZ} and @code{PROT} are sent, etc.). +Implicit FTPS is no longer a requirement for FTPS implementations, and thus +many servers may not support it. If @samp{--ftps-implicit} is passed and no explicit +port number specified, the default port for implicit FTPS, 990, will be used, instead +of the default port for the "normal" (explicit) FTPS which is the same as that of FTP, +21. + +@item --no-ftps-resume-ssl +Do not resume the SSL/TLS session in the data channel. When starting a data connection, +Wget tries to resume the SSL/TLS session previously started in the control connection. +SSL/TLS session resumption avoids performing an entirely new handshake by reusing +the SSL/TLS parameters of a previous session. Typically, the FTPS servers want it that way, +so Wget does this by default. Under rare circumstances however, one might want to +start an entirely new SSL/TLS session in every data connection. +This is what @samp{--no-ftps-resume-ssl} is for. + +@item --ftps-clear-data-connection +All the data connections will be in plain text. Only the control connection will be +under SSL/TLS. Wget will send a @code{PROT C} command to achieve this, which must be +approved by the server. + +@item --ftps-fallback-to-ftp +Fall back to FTP if FTPS is not supported by the target server. For security reasons, +this option is not asserted by default. The default behaviour is to exit with an error. +If a server does not successfully reply to the initial @code{AUTH TLS} command, or in the +case of implicit FTPS, if the initial SSL/TLS connection attempt is rejected, it is +considered that such server does not support FTPS. +@end table + +@node Recursive Retrieval Options, Recursive Accept/Reject Options, FTP Options, Invoking +@section Recursive Retrieval Options + +@table @samp +@item -r +@itemx --recursive +Turn on recursive retrieving. @xref{Recursive Download}, for more +details. The default maximum depth is 5. + +@item -l @var{depth} +@itemx --level=@var{depth} +Set the maximum number of subdirectories that Wget will recurse into to @var{depth}. +In order to prevent one from accidentally downloading very large websites when using recursion +this is limited to a depth of 5 by default, i.e., it will traverse at most 5 directories deep +starting from the provided URL. +Set @samp{-l 0} or @samp{-l inf} for infinite recursion depth. + +@example +wget -r -l 0 http://@var{site}/1.html +@end example + +Ideally, one would expect this to download just @file{1.html}. +but unfortunately this is not the case, because @samp{-l 0} is equivalent to +@samp{-l inf}---that is, infinite recursion. To download a single @sc{html} +page (or a handful of them), specify them all on the command line and leave away @samp{-r} +and @samp{-l}. To download the essential items to view a single @sc{html} page, see @samp{page requisites}. + +@cindex proxy filling +@cindex delete after retrieval +@cindex filling proxy cache +@item --delete-after +This option tells Wget to delete every single file it downloads, +@emph{after} having done so. It is useful for pre-fetching popular +pages through a proxy, e.g.: + +@example +wget -r -nd --delete-after http://whatever.com/~popular/page/ +@end example + +The @samp{-r} option is to retrieve recursively, and @samp{-nd} to not +create directories. + +Note that @samp{--delete-after} deletes files on the local machine. It +does not issue the @samp{DELE} command to remote FTP sites, for +instance. Also note that when @samp{--delete-after} is specified, +@samp{--convert-links} is ignored, so @samp{.orig} files are simply not +created in the first place. + +@cindex conversion of links +@cindex link conversion +@item -k +@itemx --convert-links +After the download is complete, convert the links in the document to +make them suitable for local viewing. This affects not only the visible +hyperlinks, but any part of the document that links to external content, +such as embedded images, links to style sheets, hyperlinks to non-@sc{html} +content, etc. + +Each link will be changed in one of the two ways: + +@itemize @bullet +@item +The links to files that have been downloaded by Wget will be changed to +refer to the file they point to as a relative link. + +Example: if the downloaded file @file{/foo/doc.html} links to +@file{/bar/img.gif}, also downloaded, then the link in @file{doc.html} +will be modified to point to @samp{../bar/img.gif}. This kind of +transformation works reliably for arbitrary combinations of directories. + +@item +The links to files that have not been downloaded by Wget will be changed +to include host name and absolute path of the location they point to. + +Example: if the downloaded file @file{/foo/doc.html} links to +@file{/bar/img.gif} (or to @file{../bar/img.gif}), then the link in +@file{doc.html} will be modified to point to +@file{http://@var{hostname}/bar/img.gif}. +@end itemize + +Because of this, local browsing works reliably: if a linked file was +downloaded, the link will refer to its local name; if it was not +downloaded, the link will refer to its full Internet address rather than +presenting a broken link. The fact that the former links are converted +to relative links ensures that you can move the downloaded hierarchy to +another directory. + +Note that only at the end of the download can Wget know which links have +been downloaded. Because of that, the work done by @samp{-k} will be +performed at the end of all the downloads. + +@item --convert-file-only +This option converts only the filename part of the URLs, leaving the rest +of the URLs untouched. This filename part is sometimes referred to as the +"basename", although we avoid that term here in order not to cause confusion. + +It works particularly well in conjunction with @samp{--adjust-extension}, although +this coupling is not enforced. It proves useful to populate Internet caches +with files downloaded from different hosts. + +Example: if some link points to @file{//foo.com/bar.cgi?xyz} with +@samp{--adjust-extension} asserted and its local destination is intended to be +@file{./foo.com/bar.cgi?xyz.css}, then the link would be converted to +@file{//foo.com/bar.cgi?xyz.css}. Note that only the filename part has been +modified. The rest of the URL has been left untouched, including the net path +(@code{//}) which would otherwise be processed by Wget and converted to the +effective scheme (ie. @code{http://}). + +@cindex backing up converted files +@item -K +@itemx --backup-converted +When converting a file, back up the original version with a @samp{.orig} +suffix. Affects the behavior of @samp{-N} (@pxref{HTTP Time-Stamping +Internals}). + +@item -m +@itemx --mirror +Turn on options suitable for mirroring. This option turns on recursion +and time-stamping, sets infinite recursion depth and keeps @sc{ftp} +directory listings. It is currently equivalent to +@samp{-r -N -l inf --no-remove-listing}. + +@cindex page requisites +@cindex required images, downloading +@item -p +@itemx --page-requisites +This option causes Wget to download all the files that are necessary to +properly display a given @sc{html} page. This includes such things as +inlined images, sounds, and referenced stylesheets. + +Ordinarily, when downloading a single @sc{html} page, any requisite documents +that may be needed to display it properly are not downloaded. Using +@samp{-r} together with @samp{-l} can help, but since Wget does not +ordinarily distinguish between external and inlined documents, one is +generally left with ``leaf documents'' that are missing their +requisites. + +For instance, say document @file{1.html} contains an @code{<IMG>} tag +referencing @file{1.gif} and an @code{<A>} tag pointing to external +document @file{2.html}. Say that @file{2.html} is similar but that its +image is @file{2.gif} and it links to @file{3.html}. Say this +continues up to some arbitrarily high number. + +If one executes the command: + +@example +wget -r -l 2 http://@var{site}/1.html +@end example + +then @file{1.html}, @file{1.gif}, @file{2.html}, @file{2.gif}, and +@file{3.html} will be downloaded. As you can see, @file{3.html} is +without its requisite @file{3.gif} because Wget is simply counting the +number of hops (up to 2) away from @file{1.html} in order to determine +where to stop the recursion. However, with this command: + +@example +wget -r -l 2 -p http://@var{site}/1.html +@end example + +all the above files @emph{and} @file{3.html}'s requisite @file{3.gif} +will be downloaded. Similarly, + +@example +wget -r -l 1 -p http://@var{site}/1.html +@end example + +will cause @file{1.html}, @file{1.gif}, @file{2.html}, and @file{2.gif} +to be downloaded. One might think that: + +@example +wget -r -l 0 -p http://@var{site}/1.html +@end example + +would download just @file{1.html} and @file{1.gif}, but unfortunately +this is not the case, because @samp{-l 0} is equivalent to +@samp{-l inf}---that is, infinite recursion. To download a single @sc{html} +page (or a handful of them, all specified on the command-line or in a +@samp{-i} @sc{url} input file) and its (or their) requisites, simply leave off +@samp{-r} and @samp{-l}: + +@example +wget -p http://@var{site}/1.html +@end example + +Note that Wget will behave as if @samp{-r} had been specified, but only +that single page and its requisites will be downloaded. Links from that +page to external documents will not be followed. Actually, to download +a single page and all its requisites (even if they exist on separate +websites), and make sure the lot displays properly locally, this author +likes to use a few options in addition to @samp{-p}: + +@example +wget -E -H -k -K -p http://@var{site}/@var{document} +@end example + +To finish off this topic, it's worth knowing that Wget's idea of an +external document link is any URL specified in an @code{<A>} tag, an +@code{<AREA>} tag, or a @code{<LINK>} tag other than @code{<LINK +REL="stylesheet">}. + +@cindex @sc{html} comments +@cindex comments, @sc{html} +@item --strict-comments +Turn on strict parsing of @sc{html} comments. The default is to terminate +comments at the first occurrence of @samp{-->}. + +According to specifications, @sc{html} comments are expressed as @sc{sgml} +@dfn{declarations}. Declaration is special markup that begins with +@samp{<!} and ends with @samp{>}, such as @samp{<!DOCTYPE ...>}, that +may contain comments between a pair of @samp{--} delimiters. @sc{html} +comments are ``empty declarations'', @sc{sgml} declarations without any +non-comment text. Therefore, @samp{<!--foo-->} is a valid comment, and +so is @samp{<!--one-- --two-->}, but @samp{<!--1--2-->} is not. + +On the other hand, most @sc{html} writers don't perceive comments as anything +other than text delimited with @samp{<!--} and @samp{-->}, which is not +quite the same. For example, something like @samp{<!------------>} +works as a valid comment as long as the number of dashes is a multiple +of four (!). If not, the comment technically lasts until the next +@samp{--}, which may be at the other end of the document. Because of +this, many popular browsers completely ignore the specification and +implement what users have come to expect: comments delimited with +@samp{<!--} and @samp{-->}. + +Until version 1.9, Wget interpreted comments strictly, which resulted in +missing links in many web pages that displayed fine in browsers, but had +the misfortune of containing non-compliant comments. Beginning with +version 1.9, Wget has joined the ranks of clients that implements +``naive'' comments, terminating each comment at the first occurrence of +@samp{-->}. + +If, for whatever reason, you want strict comment parsing, use this +option to turn it on. +@end table + +@node Recursive Accept/Reject Options, Exit Status, Recursive Retrieval Options, Invoking +@section Recursive Accept/Reject Options + +@table @samp +@item -A @var{acclist} --accept @var{acclist} +@itemx -R @var{rejlist} --reject @var{rejlist} +Specify comma-separated lists of file name suffixes or patterns to +accept or reject (@pxref{Types of Files}).

This means that Wget first downloads the requested +document, then the documents linked from that document, then the +documents linked by them, and so on. In other words, Wget first +downloads the documents at depth 1, then those at depth 2, and so on +until the specified maximum depth. + +The maximum @dfn{depth} to which the retrieval may descend is specified +with the @samp{-l} option. The default maximum depth is five layers. + +When retrieving an @sc{ftp} @sc{url} recursively, Wget will retrieve all +the data from the given directory tree (including the subdirectories up +to the specified depth) on the remote server, creating its mirror image +locally. @sc{ftp} retrieval is also limited by the @code{depth} +parameter. Unlike @sc{http} recursion, @sc{ftp} recursion is performed +depth-first. + +By default, Wget will create a local directory tree, corresponding to +the one found on the remote server. + +Recursive retrieving can find a number of applications, the most +important of which is mirroring. It is also useful for @sc{www} +presentations, and any other opportunities where slow network +connections should be bypassed by storing the files locally. + +You should be warned that recursive downloads can overload the remote +servers. Because of that, many administrators frown upon them and may +ban access from your site if they detect very fast downloads of big +amounts of content. When downloading from Internet servers, consider +using the @samp{-w} option to introduce a delay between accesses to the +server. The download will take a while longer, but the server +administrator will not be alarmed by your rudeness. + +Of course, recursive download may cause problems on your machine. If +left to run unchecked, it can easily fill up the disk. If downloading +from local network, it can also take bandwidth on the system, as well as +consume memory and CPU. + +Try to specify the criteria that match the kind of download you are +trying to achieve. If you want to download only one page, use +@samp{--page-requisites} without any additional recursion. If you want +to download things under one directory, use @samp{-np} to avoid +downloading things from other directories. If you want to download all +the files from one directory, use @samp{-l 1} to make sure the recursion +depth never exceeds one. @xref{Following Links}, for more information +about this. + +Recursive retrieval should be used with care.

This is a reasonable +default; without it, every retrieval would have the potential to turn +your Wget into a small version of google. + +However, visiting different hosts, or @dfn{host spanning,} is sometimes +a useful option. Maybe the images are served from a different server. +Maybe you're mirroring a site that consists of pages interlinked between +three servers. Maybe the server has two equivalent names, and the @sc{html} +pages refer to both interchangeably. + +@table @asis +@item Span to any host---@samp{-H} + +The @samp{-H} option turns on host spanning, thus allowing Wget's +recursive run to visit any host referenced by a link.

A suffix +is the ending part of a file, and consists of ``normal'' letters, +e.g. @samp{gif} or @samp{.jpg}. A matching pattern contains shell-like +wildcards, e.g. @samp{books*} or @samp{zelazny*196[0-9]*}. + +So, specifying @samp{wget -A gif,jpg} will make Wget download only the +files ending with @samp{gif} or @samp{jpg}, i.e. @sc{gif}s and +@sc{jpeg}s. On the other hand, @samp{wget -A "zelazny*196[0-9]*"} will +download only files beginning with @samp{zelazny} and containing numbers +from 1960 to 1969 anywhere within. Look up the manual of your shell for +a description of how pattern matching works. + +Of course, any number of suffixes and patterns can be combined into a +comma-separated list, and given as an argument to @samp{-A}. + +The argument to @samp{--accept-regex} option is a regular expression which +is matched against the complete URL. + +@cindex reject wildcards +@cindex reject suffixes +@cindex wildcards, reject +@cindex suffixes, reject +@item -R @var{rejlist} +@itemx --reject @var{rejlist} +@itemx reject = @var{rejlist} +@itemx --reject-regex @var{urlregex} +@itemx reject-regex = @var{urlregex} +The @samp{--reject} option works the same way as @samp{--accept}, only +its logic is the reverse; Wget will download all files @emph{except} the +ones matching the suffixes (or patterns) in the list. + +So, if you want to download a whole page except for the cumbersome +@sc{mpeg}s and @sc{.au} files, you can use @samp{wget -R mpg,mpeg,au}. +Analogously, to download all files except the ones beginning with +@samp{bjork}, use @samp{wget -R "bjork*"}.

This behavior may not be desirable for all users, and may be +changed for future versions of Wget. + +Note, too, that query strings (strings at the end of a URL beginning +with a question mark (@samp{?}) are not included as part of the +filename for accept/reject rules, even though these will actually +contribute to the name chosen for the local file. It is expected that +a future version of Wget will provide an option to allow matching +against query strings. + +Finally, it's worth noting that the accept/reject lists are matched +@emph{twice} against downloaded files: once against the URL's filename +portion, to determine if the file should be downloaded in the first +place; then, after it has been accepted and successfully downloaded, +the local file's name is also checked against the accept/reject lists +to see if it should be removed. The rationale was that, since +@samp{.htm} and @samp{.html} files are always downloaded regardless of +accept/reject rules, they should be removed @emph{after} being +downloaded and scanned for links, if they did match the accept/reject +lists. However, this can lead to unexpected results, since the local +filenames can differ from the original URL filenames in the following +ways, all of which can change whether an accept/reject rule matches: + +@itemize @bullet +@item +If the local file already exists and @samp{--no-directories} was +specified, a numeric suffix will be appended to the original name. +@item +If @samp{--adjust-extension} was specified, the local filename might have +@samp{.html} appended to it. If Wget is invoked with @samp{-E -A.php}, +a filename such as @samp{index.php} will match be accepted, but upon +download will be named @samp{index.php.html}, which no longer matches, +and so the file will be deleted. +@item +Query strings do not contribute to URL matching, but are included in +local filenames, and so @emph{do} contribute to filename matching. +@end itemize + +@noindent +This behavior, too, is considered less-than-desirable, and may change +in a future version of Wget. + +@node Directory-Based Limits, Relative Links, Types of Files, Following Links +@section Directory-Based Limits +@cindex directories +@cindex directory limits + +Regardless of other link-following facilities, it is often useful to +place the restriction of what files to retrieve based on the directories +those files are placed in.

HTTP has no concept of a ``directory''---Wget +relies on you to indicate what's a directory and what isn't. In +@samp{http://foo/bar/}, Wget will consider @samp{bar} to be a +directory, while in @samp{http://foo/bar} (no trailing slash), +@samp{bar} will be considered a filename (so @samp{--no-parent} would be +meaningless, as its parent is @samp{/}). +@end table + +@node Relative Links, FTP Links, Directory-Based Limits, Following Links +@section Relative Links +@cindex relative links + +When @samp{-L} is turned on, only the relative links are ever followed. +Relative links are here defined those that do not refer to the web +server root.

When a cached resource is +requested again, proxy will return the data from cache. Another use for +proxies is for companies that separate (for security reasons) their +internal networks from the rest of Internet. In order to obtain +information from the Web, their users connect and retrieve remote data +using an authorized proxy. + +@c man begin ENVIRONMENT +Wget supports proxies for both @sc{http} and @sc{ftp} retrievals. The +standard way to specify proxy location, which Wget recognizes, is using +the following environment variables: + +@table @env +@item http_proxy +@itemx https_proxy +If set, the @env{http_proxy} and @env{https_proxy} variables should +contain the @sc{url}s of the proxies for @sc{http} and @sc{https} +connections respectively. + +@item ftp_proxy +This variable should contain the @sc{url} of the proxy for @sc{ftp} +connections. It is quite common that @env{http_proxy} and +@env{ftp_proxy} are set to the same @sc{url}. + +@item no_proxy +This variable should contain a comma-separated list of domain extensions +proxy should @emph{not} be used for. For instance, if the value of +@env{no_proxy} is @samp{.mit.edu}, proxy will not be used to retrieve +documents from MIT. +@end table +@c man end + +In addition to the environment variables, proxy location and settings +may be specified from within Wget itself. + +@table @samp +@item --no-proxy +@itemx proxy = on/off +This option and the corresponding command may be used to suppress the +use of proxy, even if the appropriate environment variables are set. + +@item http_proxy = @var{URL} +@itemx https_proxy = @var{URL} +@itemx ftp_proxy = @var{URL} +@itemx no_proxy = @var{string} +These startup file variables allow you to override the proxy settings +specified by the environment. +@end table + +Some proxy servers require authorization to enable you to use them. The +authorization consists of @dfn{username} and @dfn{password}, which must +be sent by Wget. As with @sc{http} authorization, several +authentication schemes exist. For proxy authorization only the +@code{Basic} authentication scheme is currently implemented. + +You may specify your username and password either through the proxy +@sc{url} or through the command-line options. Assuming that the +company's proxy is located at @samp{proxy.company.com} at port 8001, a +proxy @sc{url} location containing authorization data might look like +this: + +@example +http://hniksic:mypassword@@proxy.company.com:8001/ +@end example + +Alternatively, you may use the @samp{proxy-user} and +@samp{proxy-password} options, and the equivalent @file{.wgetrc} +settings @code{proxy_user} and @code{proxy_password} to set the proxy +username and password. + +@node Distribution, Web Site, Proxies, Various +@section Distribution +@cindex latest version + +Like all GNU utilities, the latest version of Wget can be found at the +master GNU archive site ftp.gnu.org, and its mirrors.

If +Wget crashes, it's a bug. If Wget does not behave as documented, +it's a bug. If things work strange, but you are not sure about the way +they are supposed to work, it might well be a bug, but you might want to +double-check the documentation and the mailing lists (@pxref{Mailing +Lists}). + +@item +Try to repeat the bug in as simple circumstances as possible. E.g. if +Wget crashes while downloading @samp{wget -rl0 -kKE -t5 --no-proxy +http://example.com -o /tmp/log}, you should try to see if the crash is +repeatable, and if will occur with a simpler set of options. You might +even try to start the download at the page where the crash occurred to +see if that page somehow triggered the crash. + +Also, while I will probably be interested to know the contents of your +@file{.wgetrc} file, just dumping it into the debug message is probably +a bad idea. Instead, you should first try to see if the bug repeats +with @file{.wgetrc} moved out of the way. Only if it turns out that +@file{.wgetrc} settings affect the bug, mail me the relevant parts of +the file. + +@item +Please start Wget with @samp{-d} option and send us the resulting +output (or relevant parts thereof). If Wget was compiled without +debug support, recompile it---it is @emph{much} easier to trace bugs +with debug support on. + +Note: please make sure to remove any potentially sensitive information +from the debug log before sending it to the bug address. The +@code{-d} won't go out of its way to collect sensitive information, +but the log @emph{will} contain a fairly complete transcript of Wget's +communication with the server, which may include passwords and pieces +of downloaded data. Since the bug address is publicly archived, you +may assume that all bug reports are visible to the public. + +@item +If Wget has crashed, try to run it in a debugger, e.g. @code{gdb `which +wget` core} and type @code{where} to get the backtrace. This may not +work if the system administrator has disabled core files, but it is +safe to try. +@end enumerate +@c man end + +@node Portability, Signals, Reporting Bugs, Various +@section Portability +@cindex portability +@cindex operating systems + +Like all GNU software, Wget works on the GNU system. However, since it +uses GNU Autoconf for building and configuring, and mostly avoids using +``special'' features of any particular Unix, it should compile (and +work) on all common Unix flavors. + +Various Wget versions have been compiled and tested under many kinds of +Unix systems, including GNU/Linux, Solaris, SunOS 4.x, Mac OS X, OSF +(aka Digital Unix or Tru64), Ultrix, *BSD, IRIX, AIX, and others. Some +of those systems are no longer in widespread use and may not be able to +support recent versions of Wget. If Wget fails to compile on your +system, we would like to know about it. + +Thanks to kind contributors, this version of Wget compiles and works +on 32-bit Microsoft Windows platforms. It has been compiled +successfully using MS Visual C++ 6.0, Watcom, Borland C, and GCC +compilers. Naturally, it is crippled of some features available on +Unix, but it should work as a substitute for people stuck with +Windows. Note that Windows-specific portions of Wget are not +guaranteed to be supported in the future, although this has been the +case in practice for many years now. All questions and problems in +Windows usage should be reported to Wget mailing list at +@email{wget@@sunsite.dk} where the volunteers who maintain the +Windows-related features might look at them. + +Support for building on MS-DOS via DJGPP has been contributed by Gisle +Vanem; a port to VMS is maintained by Steven Schweda, and is available +at @url{https://antinode.info/dec/sw/wget.html}. + +@node Signals, , Portability, Various +@section Signals +@cindex signal handling +@cindex hangup + +Since the purpose of Wget is background work, it catches the hangup +signal (@code{SIGHUP}) and ignores it. If the output was on standard +output, it will be redirected to a file named @file{wget-log}. +Otherwise, @code{SIGHUP} is ignored. This is convenient when you wish +to redirect the output of Wget after having started it. + +@example +$ wget http://www.gnus.org/dist/gnus.tar.gz & +... +$ kill -HUP %% +SIGHUP received, redirecting output to `wget-log'. +@end example + +Other than that, Wget will not try to interfere with signals in any way. +@kbd{C-c}, @code{kill -TERM} and @code{kill -KILL} should kill it alike. + +@node Appendices, Copying this manual, Various, Top +@chapter Appendices + +This chapter contains some references I consider useful. + +@menu +* Robot Exclusion:: Wget's support for RES. +* Security Considerations:: Security with Wget. +* Contributors:: People who helped. +@end menu + +@node Robot Exclusion, Security Considerations, Appendices, Appendices +@section Robot Exclusion +@cindex robot exclusion +@cindex robots.txt +@cindex server maintenance + +It is extremely easy to make Wget wander aimlessly around a web site, +sucking all the available data in progress. @samp{wget -r @var{site}}, +and you're set. Great? Not for the server admin. + +As long as Wget is only retrieving static pages, and doing it at a +reasonable rate (see the @samp{--wait} option), there's not much of a +problem. The trouble is that Wget can't tell the difference between the +smallest static page and the most demanding CGI. A site I know has a +section handled by a CGI Perl script that converts Info files to @sc{html} on +the fly. The script is slow, but works well enough for human users +viewing an occasional Info file. However, when someone's recursive Wget +download stumbles upon the index page that links to all the Info files +through the script, the system is brought to its knees without providing +anything useful to the user (This task of converting Info files could be +done locally and access to Info documentation for all installed GNU +software on a system is available from the @code{info} command). + +To avoid this kind of accident, as well as to preserve privacy for +documents that need to be protected from well-behaved robots, the +concept of @dfn{robot exclusion} was invented. The idea is that +the server administrators and document authors can specify which +portions of the site they wish to protect from robots and those +they will permit access. + +The most popular mechanism, and the @i{de facto} standard supported by +all the major robots, is the ``Robots Exclusion Standard'' (RES) written +by Martijn Koster et al. in 1994. It specifies the format of a text +file containing directives that instruct the robots which URL paths to +avoid. To be found by the robots, the specifications must be placed in +@file{/robots.txt} in the server root, which the robots are expected to +download and parse. + +Although Wget is not a web robot in the strictest sense of the word, it +can download large parts of the site without the user's intervention to +download an individual page. Because of that, Wget honors RES when +downloading recursively. For instance, when you issue: + +@example +wget -r http://www.example.com/ +@end example + +First the index of @samp{www.example.com} will be downloaded. If Wget +finds that it wants to download more documents from that server, it will +request @samp{http://www.example.com/robots.txt} and, if found, use it +for further downloads. @file{robots.txt} is loaded only once per each +server. + +Until version 1.8, Wget supported the first version of the standard, +written by Martijn Koster in 1994 and available at +@url{http://www.robotstxt.org/orig.html}. As of version 1.8, +Wget has supported the additional directives specified in the internet +draft @samp{<draft-koster-robots-00.txt>} titled ``A Method for Web +Robots Control''. The draft, which has as far as I know never made to +an @sc{rfc}, is available at +@url{http://www.robotstxt.org/norobots-rfc.txt}. + +This manual no longer includes the text of the Robot Exclusion Standard. + +The second, less known mechanism, enables the author of an individual +document to specify whether they want the links from the file to be +followed by a robot. This is achieved using the @code{META} tag, like +this: + +@example +<meta name="robots" content="nofollow"> +@end example + +This is explained in some detail at +@url{http://www.robotstxt.org/meta.html}. Wget supports this +method of robot exclusion in addition to the usual @file{/robots.txt} +exclusion. + +If you know what you are doing and really really wish to turn off the +robot exclusion, set the @code{robots} variable to @samp{off} in your +@file{.wgetrc}. You can achieve the same effect from the command line +using the @code{-e} switch, e.g. @samp{wget -e robots=off @var{url}...}. + +@node Security Considerations, Contributors, Robot Exclusion, Appendices +@section Security Considerations +@cindex security + +When using Wget, you must be aware that it sends unencrypted passwords +through the network, which may present a security problem. Here are the +main issues, and some solutions. + +@enumerate +@item +The passwords on the command line are visible using @code{ps}. The best +way around it is to use @code{wget -i -} and feed the @sc{url}s to +Wget's standard input, each on a separate line, terminated by @kbd{C-d}. +Another workaround is to use @file{.netrc} to store passwords; however, +storing unencrypted passwords is also considered a security risk. + +@item +Using the insecure @dfn{basic} authentication scheme, unencrypted +passwords are transmitted through the network routers and gateways. + +@item +The @sc{ftp} passwords are also in no way encrypted. There is no good +solution for this at the moment. + +@item +Although the ``normal'' output of Wget tries to hide the passwords, +debugging logs show them, in all forms.
