It will display hypertext markup + language (HTML) documents containing links to files residing on the + local system, as well as files residing on remote systems running + Gopher, HTTP, FTP, WAIS, and NNTP servers. + + Lynx has been ported to many systems, including all variants of Unix, + Windows (since Windows 95), DOS DJGPP and OS/2, as well as VMS and + OS/390. + + Lynx can be used to access information on the World Wide Web, or to + build information systems intended primarily for local access. For + example, Lynx has been used to build several Campus Wide Information + Systems (CWIS). In addition, Lynx can be used to build systems + isolated within a single LAN. + +2 Options + At start up, Lynx will load any local file or remote URL specified at + the command line. For help with URLs, press "?" or "H" while running + Lynx. Then follow the link titled, "Help on URLs." + + If more than one local file or remote URL is listed on the command + line, Lynx will open only the last interactively. All of the names + (local files and remote URLs) are added to the G)oto history. + + Lynx uses only long option names. Option names can begin with double + dash "--" as well, underscores and dashes can be intermixed in option + names (in the reference below, options are shown with one dash "-" + before them, and with underscores "_"). + + Lynx provides many command-line options. Some options require a value + (string, number or keyword). These are noted in the reference below. + The other options set boolean values in the program. There are three + types of boolean options: set, unset and toggle. If no option value is + given, these have the obvious meaning: set (to true), unset (to false), + or toggle (between true/false). For any of these, an explicit value + can be given in different forms to allow for operating system + constraints, e.g., + + -center:off + -center=off + -center- + + Lynx recognizes "1", "+", "on" and "true" for true values, and "0", + "-", "off" and "false" for false values. Other option-values are + ignored. + + The default boolean, number and string option values that are compiled + into Lynx are displayed in the help-message provided by lynx -help. + Some of those may differ according to how Lynx was built; see the help + message itself for these values. The -help option is processed in the + third pass of options-processing, so any option which sets a value, as + well as runtime configuration values are reflected in the help-message. + + - If the argument is only "-", then Lynx expects to receive the + arguments from the standard input. This is to allow for the + potentially very long command line that can be associated with + the -get_data or -post_data arguments (see below). It can also + be used to avoid having sensitive information in the invoking + command line (which would be visible to other processes on most + systems), especially when the -auth or -pauth options are used. + + -accept_all_cookies + accept all cookies. + + -anonymous + apply restrictions for anonymous account, see also + -restrictions. + + -assume_charset=MIMEname + charset for documents that do not specify it. + + -assume_local_charset=MIMEname + charset assumed for local files, i.e., files which Lynx creates + such as internal pages for the options menu. + + -assume_unrec_charset=MIMEname + use this instead of unrecognized charsets. + + -auth=ID:PASSWD + set authorization ID and password for protected documents at + startup. Be sure to protect any script files which use this + switch. + + -base prepend a request URL comment and BASE tag to text/html outputs + for -source dumps. + + -bibhost=URL + specify a local bibp server (default http://bibhost/). + + -blink forces high intensity background colors for color mode, if + available and supported by the terminal. This applies to the + slang library (for a few terminal emulators), or to OS/2 EMX + with ncurses. + + -book use the bookmark page as the startfile. The default or command + line startfile is still set for the Main screen command, and + will be used if the bookmark page is unavailable or blank. + + -buried_news + toggles scanning of news articles for buried references, and + converts them to news links. Not recommended because email + addresses enclosed in angle brackets will be converted to false + news links, and uuencoded messages can be trashed. + + -cache=NUMBER + set the NUMBER of documents cached in memory. The default is + 10. + + -case enable case-sensitive string searching. + + -center + toggles center alignment in HTML TABLE. Normally table cells + are centered on the table grid. Set this option "on" to disable + centering. The default is "off". + + -cfg=FILENAME + specifies a Lynx configuration file other than the default + lynx.cfg. + + -child exit on left-arrow in startfile, and disable save to disk and + associated print/mail options. + + -child_relaxed + exit on left-arrow in startfile, but allow save to disk and + associated print/mail options. + + -cmd_log=FILENAME + write keystroke commands and related information to the + specified file. + + -cmd_script=FILENAME + read keystroke commands from the specified file. You can use + the data written using the -cmd_log option. Lynx will ignore + other information which the command-logging may have written to + the logfile. Each line of the command script contains either a + comment beginning with "#", or a keyword: + + exit + causes the script to stop, and forces Lynx to exit + immediately. + + key + the character value, in printable form. Cursor and other + special keys are given as names, e.g., "Down Arrow". + Printable 7-bit ASCII codes are given as-is, and hexadecimal + values represent other 8-bit codes. + + set + followed by a "name=value" allows one to override values set + in the lynx.cfg or .lynxrc files. Lynx tries the cfg-file + setting first. + + -collapse_br_tags + toggles collapsing of BR tags. + + -color forces color mode on, if available. Default color control + sequences which work for many terminal types are assumed if the + terminal capability description does not specify how to handle + color. Lynx needs to be compiled with the slang library for + this flag, it is equivalent to setting the COLORTERM environment + variable. (If color support is instead provided by a color- + capable curses library like ncurses, Lynx relies completely on + the terminal description to determine whether color mode is + possible, and this flag is not needed and thus unavailable.) A + saved show_color=always setting found in a .lynxrc file at + startup has the same effect. A saved show_color=never found in + .lynxrc on startup is overridden by this flag. + + -connect_timeout=N + Sets the connection timeout, where N is given in seconds. + + -cookie_file=FILENAME + specifies a file to use to read cookies. If none is specified, + the default value is ~/.lynx_cookies for most systems, but + ~/cookies for MS-DOS. + + -cookie_save_file=FILENAME + specifies a file to use to store cookies. If none is specified, + the value given by -cookie_file is used. + + -cookies + toggles handling of Set-Cookie headers. + + -core toggles forced core dumps on fatal errors. Turn this option off + to ask Lynx to force a core dump if a fatal error occurs. + + -crawl with -traversal, output each page to a file. with -dump, format + output as with -traversal, but to the standard output. + + -curses_pads + toggles the use of curses "pad" feature which supports + left/right scrolling of the display. The feature is normally + available for curses configurations, but inactive. To activate + it, use the "|" character or the LINEWRAP_TOGGLE command. + Toggling this option makes the feature altogether unavailable. + + -debug_partial + separate incremental display stages with MessageSecs delay + + -default_colors + toggles the default-colors feature which is normally set in the + lynx.cfg file. + + -delay add DebugSecs delay after each progress-message + + -display=DISPLAY + set the display variable for X rexec-ed programs. + + -display_charset=MIMEname + set the charset for the terminal output. + + -dont_wrap_pre + inhibit wrapping of text when -dump'ing and -crawl'ing, mark + wrapped lines of <pre> in interactive session. + + -dump dumps the formatted output of the default document or those + specified on the command line to standard output. Unlike + interactive mode, all documents are processed. This can be used + in the following way: + + lynx -dump http://www.subir.com/lynx.html + + Files specified on the command line are formatted as HTML if + their names end with one of the standard web suffixes such as + ".htm" or ".html". Use the -force_html option to format files + whose names do not follow this convention. + + -editor=EDITOR + enable external editing, using the specified EDITOR. (vi, ed, + emacs, etc.) + + -emacskeys + enable emacs-like key movement. + + -enable_scrollback + toggles compatibility with communication programs' scrollback + keys (may be incompatible with some curses packages). + + -error_file=FILE + define a file where Lynx will report HTTP access codes. + + -exec enable local program execution (normally not configured). + + -fileversions + include all versions of files in local VMS directory listings. + + -find_leaks + toggle memory leak-checking. Normally this is not compiled-into + your executable, but when it is, it can be disabled for a + session. + + -force_empty_hrefless_a + force HREF-less "A" elements to be empty (close them as soon as + they are seen). + + -force_html + forces the first document to be interpreted as HTML. + + This is most useful when processing files specified on the + command line which have an unrecognized suffix (or the suffix is + associated with a non-HTML type, such as ".txt" for plain text + files). + + Lynx recognizes these file suffixes as HTML: + + ".ht3", + ".htm", + ".html3", + ".html", + ".htmlx", + ".php3", + ".php", + ".phtml", + ".sht", and + ".shtml". + + -force_secure + toggles forcing of the secure flag for SSL cookies. + + -forms_options + toggles whether the Options Menu is key-based or form-based. + + -from toggles transmissions of From headers. + + -ftp disable ftp access. + + -get_data + properly formatted data for a get form are read in from the + standard input and passed to the form. Input is terminated by a + line that starts with "---". + + Lynx issues an HTTP GET, sending the form to the path or URL + given on the command-line and prints the response of the server. + If no path or URL is given, Lynx sends the form to the start- + page. + + -head send a HEAD request for the mime headers. + + -help print the Lynx command syntax usage message, and exit. + + -hiddenlinks=[option] + control the display of hidden links. + + merge + hidden links show up as bracketed numbers and are numbered + together with other links in the sequence of their occurrence + in the document. + + listonly + hidden links are shown only on L)ist screens and listings + generated by -dump or from the P)rint menu, but appear + separately at the end of those lists. This is the default + behavior. + + ignore + hidden links do not appear even in listings. + + -historical + toggles use of ">" or "-->" as a terminator for comments. + + -homepage=URL + set homepage separate from start page. + + -image_links + toggles inclusion of links for all images. + + -index=URL + set the default index file to the specified URL. + + -ismap toggles inclusion of ISMAP links when client-side MAPs are + present. + + -justify + do justification of text. + + -link=NUMBER + starting count for lnk#.dat files produced by -crawl. + + -list_decoded + for -dump, show URL-encoded links decoded. + + -list_inline + for -dump, show the links inline with the text. + + -listonly + for -dump, show only the list of links. + + -localhost + disable URLs that point to remote hosts. + + -locexec + enable local program execution from local files only (if Lynx + was compiled with local execution enabled). + + -lss=FILENAME + specify filename containing color-style information. The + default is lynx.lss. If you give an empty filename, Lynx uses a + built-in monochrome scheme which imitates the non-color-style + configuration. + + -mime_header + prints the MIME header of a fetched document along with its + source. + + -minimal + toggles minimal versus valid comment parsing. + + -nested_tables + toggles nested-tables logic (for debugging). + + -newschunksize=NUMBER + number of articles in chunked news listings. + + -newsmaxchunk=NUMBER + maximum news articles in listings before chunking. + + -nobold + disable bold video-attribute. + + -nobrowse + disable directory browsing. + + -nocc disable Cc: prompts for self copies of mailings. Note that this + does not disable any CCs which are incorporated within a mailto + URL or form ACTION. + + -nocolor + force color mode off, overriding terminal capabilities and any + -color flags, COLORTERM variable, and saved .lynxrc settings. + + -noexec + disable local program execution. (DEFAULT) + + -nofilereferer + disable transmissions of Referer headers for file URLs. + + -nolist + disable the link list feature in dumps. + + -nolog disable mailing of error messages to document owners. + + -nomargins + disable left/right margins in the default style sheet. + + -nomore + disable -more- string in statusline messages. + + -nonrestarting_sigwinch + This flag is not available on all systems, Lynx needs to be + compiled with HAVE_SIGACTION defined. If available, this flag + may cause Lynx to react more immediately to window changes when + run within an xterm. + + -nonumbers + disable link- and field-numbering. This overrides + -number_fields and -number_links. + + -nopause + disable forced pauses for statusline messages. + + -noprint + disable most print functions. + + -noredir + prevents automatic redirection and prints a message with a link + to the new URL. + + -noreferer + disable transmissions of Referer headers. + + -noreverse + disable reverse video-attribute. + + -nosocks + disable SOCKS proxy usage by a SOCKSified Lynx. + + -nostatus + disable the retrieval status messages. + + -notitle + disable title and blank line from top of page. + + -nounderline + disable underline video-attribute. + + -number_fields + force numbering of links as well as form input fields + + -number_links + force numbering of links. + + -partial + toggles display partial pages while loading. + + -partial_thres=NUMBER + number of lines to render before repainting display with + partial-display logic + + -passive_ftp + toggles passive ftp connections. + + -pauth=ID:PASSWD + set authorization ID and password for a protected proxy server + at startup. Be sure to protect any script files which use this + switch. + + -popup toggles handling of single-choice SELECT options via popup + windows or as lists of radio buttons. + + -post_data + properly formatted data for a post form are read in from the + standard input and passed to the form. Input is terminated by a + line that starts with "---". + + Lynx issues an HTTP POST, sending the form to the path or URL + given on the command-line and prints the response of the server. + If no path or URL is given, Lynx sends the form to the start- + page. + + -preparsed + show HTML source preparsed and reformatted when used with + -source or in source view. + + -prettysrc + show HTML source view with lexical elements and tags in color. + + -print enable print functions. (default) + + -pseudo_inlines + toggles pseudo-ALTs for inline images with no ALT string. + + -raw toggles default setting of 8-bit character translations or CJK + mode for the startup character set. + + -realm restricts access to URLs in the starting realm. + + -read_timeout=N + Sets the read-timeout, where N is given in seconds. + + -reload + flushes the cache on a proxy server (only the first document + given on the command-line is affected). + + -restrictions=[option][,option][,option]... + allows a list of services to be disabled selectively. Dashes + and underscores in option names can be intermixed. The + following list is printed if no options are specified. + + all + restricts all options listed below. + + bookmark + disallow changing the location of the bookmark file. + + bookmark_exec + disallow execution links via the bookmark file. + + change_exec_perms + disallow changing the eXecute permission on files (but still + allow it for directories) when local file management is + enabled. + + default + same as command line option -anonymous. Disables default + services for anonymous users. Set to all restricted, except + for: inside_telnet, outside_telnet, inside_ftp, outside_ftp, + inside_rlogin, outside_rlogin, inside_news, outside_news, + telnet_port, jump, mail, print, exec, and goto. The settings + for these, as well as additional goto restrictions for + specific URL schemes that are also applied, are derived from + definitions within userdefs.h. + + dired_support + disallow local file management. + + disk_save + disallow saving to disk in the download and print menus. + + dotfiles + disallow access to, or creation of, hidden (dot) files. + + download + disallow some downloaders in the download menu (does not + imply disk_save restriction). + + editor + disallow external editing. + + exec + disable execution scripts. + + exec_frozen + disallow the user from changing the local execution option. + + externals + disallow some "EXTERNAL" configuration lines if support for + passing URLs to external applications (with the EXTERN + command) is compiled in. + + file_url + disallow using G)oto, served links or bookmarks for file: + URLs. + + goto + disable the "g" (goto) command. + + inside_ftp + disallow ftps for people coming from inside your domain (utmp + required for selectivity). + + inside_news + disallow USENET news posting for people coming from inside + your domain (utmp required for selectivity). + + inside_rlogin + disallow rlogins for people coming from inside your domain + (utmp required for selectivity). + + inside_telnet + disallow telnets for people coming from inside your domain + (utmp required for selectivity). + + jump + disable the "j" (jump) command. + + multibook + disallow multiple bookmarks. + + mail + disallow mail. + + news_post + disallow USENET News posting. + + options_save + disallow saving options in .lynxrc. + + outside_ftp + disallow ftps for people coming from outside your domain + (utmp required for selectivity). + + outside_news + disallow USENET news reading and posting for people coming + from outside your domain (utmp required for selectivity). + This restriction applies to "news", "nntp", "newspost", and + "newsreply" URLs, but not to "snews", "snewspost", or + "snewsreply" in case they are supported. + + outside_rlogin + disallow rlogins for people coming from outside your domain + (utmp required for selectivity). + + outside_telnet + disallow telnets for people coming from outside your domain + (utmp required for selectivity). + + print + disallow most print options. + + shell + disallow shell escapes and lynxexec or lynxprog G)oto's. + + suspend + disallow Unix Control-Z suspends with escape to shell. + + telnet_port + disallow specifying a port in telnet G)oto's. + + useragent + disallow modifications of the User-Agent header. + + -resubmit_posts + toggles forced resubmissions (no-cache) of forms with method + POST when the documents they returned are sought with the + PREV_DOC command or from the History List. + + -rlogin + disable recognition of rlogin commands. + + -scrollbar + toggles showing scrollbar. + + -scrollbar_arrow + toggles showing arrows at ends of the scrollbar. + + -selective + require .www_browsable files to browse directories. + + -session=FILENAME + resumes from specified file on startup and saves session to that + file on exit. + + -sessionin=FILENAME + resumes session from specified file. + + -sessionout=FILENAME + saves session to specified file. + + -short_url + show very long URLs in the status line with "..." to represent + the portion which cannot be displayed. The beginning and end of + the URL are displayed, rather than suppressing the end. + + -show_cfg + Print the configuration settings, e.g., as read from "lynx.cfg", + and exit. + + -show_cursor + If enabled the cursor will not be hidden in the right hand + corner but will instead be positioned at the start of the + currently selected link. Show cursor is the default for systems + without FANCY_CURSES capabilities. The default configuration + can be changed in userdefs.h or lynx.cfg. The command line + switch toggles the default. + + -show_rate + If enabled the transfer rate is shown in bytes/second. If + disabled, no transfer rate is shown. Use lynx.cfg or the + options menu to select KB/second and/or ETA. + + -socks5_proxy=URL + (Via which) SOCKS5 proxy to connect: any network traffic, + including all DNS resolutions but the one for URL itself, will + be redirected through the SOCKS5 proxy. URL may be given as + "proxy.example.com", "proxy.example.com:1080", "192.168.0.1", or + "192.168.0.1:1080" (and IPv6 notation if so supported). A + SOCKS5 proxy may also be specified via the environment variable + SOCKS5_PROXY. This option controls the builtin SOCKS5 support, + which is unrelated to the option -nosocks. + + -soft_dquotes + toggles emulation of the old Netscape and Mosaic bug which + treated ">" as a co-terminator for double-quotes and tags. + + -source + works the same as dump but outputs HTML source instead of + formatted text. For example + + lynx -source . >foo.html + + generates HTML source listing the files in the current + directory. Each file is marked by an HREF relative to the + parent directory. Add a trailing slash to make the HREF's + relative to the current directory: + + lynx -source ./ >foo.html + + -stack_dump + disable SIGINT cleanup handler + + -startfile_ok + allow non-http startfile and homepage with -validate. + + -stderr + When dumping a document using -dump or -source, Lynx normally + does not display alert (error) messages that you see on the + screen in the status line. Use the -stderr option to tell Lynx + to write these messages to the standard error. + + -stdin read the startfile from standard input (UNIX only). + + -syslog=text + information for syslog call. + + -syslog_urls + log requested URLs with syslog. + + -tagsoup + initialize parser, using Tag Soup DTD rather than SortaSGML. + + -telnet + disable recognition of telnet commands. + + -term=TERM + tell Lynx what terminal type to assume it is talking to. (This + may be useful for remote execution, when, for example, Lynx + connects to a remote TCP/IP port that starts a script that, in + turn, starts another Lynx process.) + + -timeout=N + For win32, sets the network read-timeout, where N is given in + seconds. + + -tlog toggles between using a Lynx Trace Log and stderr for trace + output from the session. + + -tna turns on "Textfields Need Activation" mode. + + -trace turns on Lynx trace mode. Destination of trace output depends + on -tlog. + + -trace_mask=value + turn on optional traces, which may result in very large trace + files. Logically OR the values to combine options: + + 1 SGML character parsing states + + 2 color-style + + 4 TRST (table layout) + + 8 configuration (lynx.cfg, .lynxrc, .lynx-keymaps, mime.types + and mailcap contents) + + 16 binary string copy/append, used in form data construction. + + 32 cookies + + 64 character sets + + 128 + GridText parsing + + 256 + timing + + 512 + detailed URL parsing + + -traversal + traverse all http links derived from startfile. When used with + -crawl, each link that begins with the same string as startfile + is output to a file, intended for indexing. + + See CRAWL.announce for more information. + + -trim_blank_lines + toggles trimming of trailing blank lines as well as the related + trimming of blank lines while collapsing BR tags. + + -trim_input_fields + trim input text/textarea fields in forms. + + -underline_links + toggles use of underline/bold attribute for links. + + -underscore + toggles use of _underline_ format in dumps. + + -unique_urls + check for duplicate link numbers in each page and corresponding + lists, and reuse the original link number. + + -update_term_title + enables updating the title in terminal emulators. Use only if + your terminal emulator supports that escape code. Has no effect + when used with -notitle. + + -use_mouse + turn on mouse support, if available. Clicking the left mouse + button on a link traverses it. Clicking the right mouse button + pops back. Click on the top line to scroll up. Click on the + bottom line to scroll down. The first few positions in the top + and bottom line may invoke additional functions. Lynx must be + compiled with ncurses or slang to support this feature. If + ncurses is used, clicking the middle mouse button pops up a + simple menu. Mouse clicks may only work reliably while Lynx is + idle waiting for input. + + -useragent=Name + set alternate Lynx User-Agent header. + + -validate + accept only http URLs (for validation). Complete security + restrictions also are implemented. + + -verbose + toggle [LINK], [IMAGE] and [INLINE] comments with filenames of + these images. + + -version + print version information, and exit. + + -vikeys + enable vi-like key movement. + + -wdebug + enable Waterloo tcp/ip packet debug (print to watt debugfile). + This applies only to DOS versions compiled with WATTCP or + WATT-32. + + -width=NUMBER + number of columns for formatting of dumps, default is 80. This + is limited by the number of columns that Lynx could display, + typically 1024 (the MAX_LINE symbol). + + -with_backspaces + emit backspaces in output if -dump'ing or -crawl'ing (like man + does) + + -xhtml_parsing + tells Lynx that it can ignore certain tags which have no content + in an XHTML 1.0 document. For example "<p/>" will be discarded. + +2 Commands + More than one key can be mapped to a given command. Here are some of + the most useful: + + * Use Up arrow and Down arrow to scroll through hypertext links. + + * Right arrow or Return will follow a highlighted hypertext link. + + * Left Arrow or "u" will retreat from a link. + + * Type "H", "?", or F1 for online help and descriptions of key-stroke + commands. + + * Type "k" or "K" for a list of the current key-stroke command + mappings. + + If the same command is mapped to the same letter differing only by + upper/lowercase only the lowercase mapping is shown. + + * Type Delete to view history list. + +2 Environment + In addition to various "standard" environment variables such as + DISPLAY, HOME, PATH, SHELL, TMPDIR, USER, etc., Lynx utilizes several + Lynx-specific environment variables, if they exist. + + Others may be created or modified by Lynx to pass data to an external + program, or for other reasons. These are listed separately below. + + See also the sections on SIMULATED CGI SUPPORT and NATIVE LANGUAGE + SUPPORT, below. + + Note: Not all environment variables apply to all types of platforms + supported by Lynx, though most do. Feedback on platform dependencies + is solicited. + + Environment Variables Used By Lynx: + + COLORTERM If set, color capability for the terminal is forced + on at startup time. The actual value assigned to + the variable is ignored. This variable is only + meaningful if Lynx was built using the slang + screen-handling library. + + LYNX_CFG This variable, if set, will override the default + location and name of the global configuration file + (normally, lynx.cfg) that was defined by the + LYNX_CFG_FILE constant in the userdefs.h file, + during installation. + + See the userdefs.h file for more information. + + LYNX_CFG_PATH If set, this variable overrides the compiled-in + search-list of directories used to find the + configuration files, e.g., lynx.cfg and lynx.lss. + The list is delimited with ":" (or ";" for Windows) + like the PATH environment variable. + + LYNX_HELPFILE If set, this variable overrides the compiled-in URL + and configuration file URL for the Lynx help file. + + LYNX_LOCALEDIR If set, this variable overrides the compiled-in + location of the locale directory which contains + native language (NLS) message text. + + LYNX_LSS This variable, if set, specifies the location of + the default Lynx character style sheet file. + [Currently only meaningful if Lynx was built using + curses color style support.] + + LYNX_SAVE_SPACE This variable, if set, will override the default + path prefix for files saved to disk that is defined + in the lynx.cfg SAVE_SPACE: statement. + + See the lynx.cfg file for more information. + + LYNX_TEMP_SPACE This variable, if set, will override the default + path prefix for temporary files that was defined + during installation, as well as any value that may + be assigned to the TMPDIR variable. + + MAIL This variable specifies the default inbox Lynx will + check for new mail, if such checking is enabled in + the lynx.cfg file. + + NEWS_ORGANIZATION This variable, if set, provides the string used in + the Organization: header of USENET news postings. + It will override the setting of the ORGANIZATION + environment variable, if it is also set (and, on + UNIX, the contents of an /etc/organization file, if + present). + + NNTPSERVER If set, this variable specifies the default NNTP + server that will be used for USENET news reading + and posting with Lynx, via news: URL's. + + ORGANIZATION This variable, if set, provides the string used in + the Organization: header of USENET news postings. + On UNIX, it will override the contents of an + /etc/organization file, if present. + + PROTOCOL_proxy Lynx supports the use of proxy servers that can act + as firewall gateways and caching servers. They are + preferable to the older gateway servers (see + WWW_access_GATEWAY, below). + + Each protocol used by Lynx, (http, ftp, gopher, + etc), can be mapped separately by setting + environment variables of the form PROTOCOL_proxy. + Protocols are indicated in a URI by the name before + ":", e.g., "http" in "http://some.server.dom:port/" + for HTML. + + Depending on your system configuration and + supported protocols, the environment variables + recognized by lynx may include + + cso_proxy + finger_proxy + ftp_proxy + gopher_proxy + http_proxy + https_proxy + news_proxy + newspost_proxy + newsreply_proxy + nntp_proxy + no_proxy + rlogin_proxy + snews_proxy + snewspost_proxy + snewsreply_proxy + telnet_proxy + tn3270_proxy + wais_proxy + + See Lynx Users Guide for additional details and + examples. + + RL_CLCOPY_CMD Pipe the contents of the current link using this + command as the target. + + RL_PASTE_CMD Open a pipe to read from this command, pasting it + into the current editable-field or command-prompt. + + SOCKS5_PROXY Is inspected if -socks5_proxy has not been used + (for the same content). + + SSL_CERT_DIR Set to the directory containing trusted + certificates. + + SSL_CERT_FILE Set to the full path and filename for your file of + trusted certificates. + + WWW_access_GATEWAY Lynx still supports use of gateway servers, with + the servers specified via "WWW_access_GATEWAY" + variables (where "access" is lower case and can be + "http", "ftp", "gopher" or "wais"). However most + gateway servers have been discontinued. Note that + you do not include a terminal "/" for gateways, but + do for proxies specified by PROTOCOL_proxy + environment variables. + + See Lynx Users Guide for details. + + WWW_HOME This variable, if set, will override the default + startup URL specified in any of the Lynx + configuration files. + + Environment Variables Set or Modified By Lynx: + + LYNX_PRINT_DATE This variable is set by the Lynx p(rint) function, + to the Date: string seen in the document's + "Information about" page (= cmd), if any. It is + created for use by an external program, as defined + in a lynx.cfg PRINTER: definition statement. If + the field does not exist for the document, the + variable is set to a null string under UNIX, or "No + Date" under VMS. + + LYNX_PRINT_LASTMOD This variable is set by the Lynx p(rint) function, + to the Last Mod: string seen in the document's + "Information about" page (= cmd), if any. It is + created for use by an external program, as defined + in a lynx.cfg PRINTER: definition statement. If + the field does not exist for the document, the + variable is set to a null string under UNIX, or "No + LastMod" under VMS. + + LYNX_PRINT_TITLE This variable is set by the Lynx p(rint) function, + to the Linkname: string seen in the document's + "Information about" page (= cmd), if any. It is + created for use by an external program, as defined + in a lynx.cfg PRINTER: definition statement. If + the field does not exist for the document, the + variable is set to a null string under UNIX, or "No + Title" under VMS. + + LYNX_PRINT_URL This variable is set by the Lynx p(rint) function, + to the URL: string seen in the document's + "Information about" page (= cmd), if any. It is + created for use by an external program, as defined + in a lynx.cfg PRINTER: definition statement. If + the field does not exist for the document, the + variable is set to a null string under UNIX, or "No + URL" under VMS. + + LYNX_TRACE If set, causes Lynx to write a trace file as if the + -trace option were supplied. + + LYNX_TRACE_FILE If set, overrides the compiled-in name of the trace + file, which is either Lynx.trace or LY-TRACE.LOG + (the latter on the DOS/Windows platforms). The + trace file is in either case relative to the home + directory. + + LYNX_VERSION This variable is always set by Lynx, and may be + used by an external program to determine if it was + invoked by Lynx. + + See also the comments in the distribution's sample + mailcap file, for notes on usage in such a file. + + TERM Normally, this variable is used by Lynx to + determine the terminal type being used to invoke + Lynx. If, however, it is unset at startup time (or + has the value "unknown"), or if the -term command- + line option is used (see OPTIONS section above), + Lynx will set or modify its value to the user + specified terminal type (for the Lynx execution + environment). Note: If set/modified by Lynx, the + values of the LINES and/or COLUMNS environment + variables may also be changed. + + Simulated CGI Support + If built with the cgi-links option enabled, Lynx allows access to a cgi + script directly without the need for an http daemon. + + When executing such "lynxcgi scripts" (if enabled), the following + variables may be set for simulating a CGI environment: + + CONTENT_LENGTH + + CONTENT_TYPE + + DOCUMENT_ROOT + + HTTP_ACCEPT_CHARSET + + HTTP_ACCEPT_LANGUAGE + + HTTP_USER_AGENT + + PATH_INFO + + PATH_TRANSLATED + + QUERY_STRING + + REMOTE_ADDR + + REMOTE_HOST + + REQUEST_METHOD + + SERVER_SOFTWARE + + Other environment variables are not inherited by the script, unless + they are provided via a LYNXCGI_ENVIRONMENT statement in the + configuration file. See the lynx.cfg file, and the (draft) CGI 1.1 + Specification <http://Web.Golux.Com/coar/cgi/draft-coar-cgi-v11-00.txt> + for the definition and usage of these variables. + + The CGI Specification, and other associated documentation, should be + consulted for general information on CGI script programming. + + Native Language Support + If configured and installed with Native Language Support, Lynx will + display status and other messages in your local language. See the file + ABOUT_NLS in the source distribution, or at your local GNU site, for + more information about internationalization. + + The following environment variables may be used to alter default + settings: + + LANG This variable, if set, will override the default + message language. It is an ISO 639 two-letter code + identifying the language. Language codes are NOT + the same as the country codes given in ISO 3166. + + LANGUAGE This variable, if set, will override the default + message language. This is a GNU extension that has + higher priority for setting the message catalog + than LANG or LC_ALL. + + LC_ALL and + + LC_MESSAGES These variables, if set, specify the notion of + native language formatting style. They are POSIXly + correct. + + LINGUAS This variable, if set prior to configuration, + limits the installed languages to specific values. + It is a space-separated list of two-letter codes. + Currently, it is hard-coded to a wish list. + + NLSPATH This variable, if set, is used as the path prefix + for message catalogs. + +2 Notes + Mailing Lists + If you wish to contribute to the further development of Lynx, subscribe + to our mailing list.

HYPERREZ was developed by Niel + Larson of Think.com and served as the model for the early versions of + Lynx. Those versions also incorporated libraries from the Unix Gopher + clients developed at the University of Minnesota, and the later + versions of Lynx rely on the WWW client library code developed by Tim + Berners-Lee and the WWW community. Also a special thanks to Foteos + Macrides who ported much of Lynx to VMS and did or organized most of + its development since the departures of Lou Montulli and Garrett Blythe + from the University of Kansas in the summer of 1994 through the release + of v2.7.2, and to everyone on the net who has contributed to Lynx's + development either directly (through patches, comments or bug reports) + or indirectly (through inspiration and development of other systems). + +2 Authors + Lou Montulli, Garrett Blythe, Craig Lavender, Michael Grobe, Charles + Rezac + Academic Computing Services + University of Kansas + Lawrence, Kansas 66047 + + Foteos Macrides + Worcester Foundation for Biomedical Research + Shrewsbury, Massachusetts 01545 + + Thomas E.
