+*************************************** + +Free software is going international! The Free Translation Project is +a way to get maintainers of free software, translators, and users all +together, so that free software will gradually become able to speak many +languages. A few packages already provide translations for their +messages. + + If you found this `ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU `gettext' internally, +itself available at your nearest GNU archive site. But you do _not_ +need to install GNU `gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work on translations can contact the appropriate team. + +1.1 INSTALL Matters +=================== + +Some packages are "localizable" when properly installed; the programs +they contain can be made to speak your own native language. Most such +packages use GNU `gettext'. Other packages have their own ways to +internationalization, predating GNU `gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system already +provides the GNU `gettext' functions. Installers may use special +options at configuration time for changing the default behaviour. The +command: + + ./configure --disable-nls + +will _totally_ disable translation of messages. + + When you already have GNU `gettext' installed on your system and run +configure without an option for your new package, `configure' will +probably detect the previously built and installed `libintl' library +and will decide to use it. If not, you may have to to use the +`--with-libintl-prefix' option to tell `configure' where to look for it. + + Internationalized packages usually have many `po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at `configure' time by using the +`--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable `LINGUAS' +may be set, prior to configuration, to limit the installed set. +`LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +1.2 Using This Package +====================== + +As a user, if your language has been installed for this package, you +only have to set the `LANG' environment variable to the appropriate +`LL_CC' combination. If you happen to have the `LC_ALL' or some other +`LC_xxx' environment variables set, you should unset them before +setting `LANG', otherwise the setting of `LANG' will not have the +desired effect. Here `LL' is an ISO 639 two-letter language code, and +`CC' is an ISO 3166 two-letter country code. For example, let's +suppose that you speak German and live in Germany. At the shell +prompt, merely execute `setenv LANG de_DE' (in `csh'), +`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). +This can be done from your `.login' or `.profile' file, once and for +all. + + You might think that the country code specification is redundant. +But in fact, some languages have dialects in different countries. For +example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The +country code serves to distinguish the dialects. + + The locale naming convention of `LL_CC', with `LL' denoting the +language and `CC' denoting the country, is the one use on systems based +on GNU libc. On other systems, some variations of this scheme are +used, such as `LL' or `LL_CC.ENCODING'. You can get the list of +locales supported by your system for your language by running the +command `locale -a | grep '^LL''. + + Not all programs have translations for all languages. By default, an +English message is shown in place of a nonexistent translation. If you +understand other languages, you can set up a priority list of languages. +This is done through a different environment variable, called +`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' +for the purpose of message handling, but you still need to have `LANG' +set to the primary language; this is required by other parts of the +system libraries. For example, some Swedish users who would rather +read translations in German than English for when Swedish is not +available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. + + Special advice for Norwegian users: The language code for Norwegian +bokma*l changed from `no' to `nb' recently (in 2003). During the +transition period, while some message catalogs for this language are +installed under `nb' and some older ones under `no', it's recommended +for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and +older translations are used. + + In the `LANGUAGE' environment variable, but not in the `LANG' +environment variable, `LL_CC' combinations can be abbreviated as `LL' +to denote the language's main dialect. For example, `de' is equivalent +to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' +(Portuguese as spoken in Portugal) in this context. + +1.3 Translating Teams +===================== + +For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list. The up-to-date list of +teams can be found at the Free Translation Project's homepage, +`http://translationproject.org/', in the "Teams" area. + + If you'd like to volunteer to _work_ at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is _not_ the same as the list itself, it has +`-request' appended. For example, speakers of Swedish can send a +message to `sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate +_actively_ in translations, or at solving translational difficulties, +rather than merely lurking around. If your team does not exist yet and +you want to start one, or if you are unsure about what to do or how to +get started, please write to `coordinator@translationproject.org' to +reach the coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skills are praised more than +programming skills, here. + +1.4 Available Packages +====================== + +Languages are not equally supported in all packages. The following +matrix shows the current state of internationalization, as of June +2010. The matrix shows, in regard of each package, for which languages +PO files have been submitted to translation coordination, with a +translation percentage of at least 50%. + + Ready PO files af am an

Of course you have to respect the GNU Library General Public +License which covers the use of the GNU `gettext' library. This means +in particular that even non-free programs can use `libintl' as a shared +library, whereas only free software can use `libintl' as a static +library or use modified versions of `libintl'. + + Once the sources are changed appropriately and the setup can handle +the use of `gettext' the only thing missing are the translations. The +Free Translation Project is also available for packages which are not +developed inside the GNU project. Therefore the information given above +applies also for every other Free Software Project. Contact +`coordinator@translationproject.org' to make the `.pot' files available +to the translation teams. + diff --git a/src/grep/AUTHORS b/src/grep/AUTHORS new file mode 100644 index 0000000..a4ce768 --- /dev/null +++ b/src/grep/AUTHORS @@ -0,0 +1,63 @@ + Copyright (C) 1992, 1997-2002, 2004-2021 Free Software Foundation, Inc. + + Copying and distribution of this file, with or without modification, + are permitted in any medium without royalty provided the copyright + notice and this notice are preserved. + +Mike Haertel wrote the main program and the dfa and kwset matchers. + +Isamu Hasegawa wrote the POSIX regular expression matcher, which is +part of the GNU C Library and is distributed as part of GNU grep for +use on non-GNU systems. Ulrich Drepper, Paul Eggert, Paolo Bonzini, +Stanislav Brabec, Assaf Gordon, Jakub Jelinek, Jim Meyering, Arnold +Robbins, Andreas Schwab and Florian Weimer also contributed to this +matcher. + +Arthur David Olson contributed the heuristics for finding fixed substrings +at the end of dfa.c. + +Henry Spencer wrote the original test suite from which grep's was derived. +Scott Anderson invented the Khadafy test. + +David MacKenzie wrote the automatic configuration software used to +produce the configure script. + +Authors of the replacements for standard library routines are identified +in the corresponding source files. + +The idea of using Boyer-Moore type algorithms to quickly filter out +non-matching text before calling the regexp matcher was originally due +to James Woods.

By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + 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, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public 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. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License.

But, in the particular + case that the token being added is MBCSET, addtok(): + + (1) incorrectly assumes that the character set being added to be added + is the one most (addtok has no argument to indicate which cset is + being added, so it just uses the latest one) + + (2) attempts to do some token sequence expansion into more primitive + operators so things like [FOO] are matched efficiently. + + Both of these assumptions are incorrect in the case that addtok() + is being called from copytoks(): (1) is simply not true, and + (2) is redundant--the expansion has already been done token sequence + being copied, so there is no need to do the expansion again. + + The correct function to add exactly one token, without further expansion, + is addtok_mb().

Those tests used to expect that two selected (or + selectable) lines be output, even with -m1. Nothing was + modified with other similar tests that output _context_ lines + after one selected line has been output with -m1; they used to + and still succeed. Although tests/yesno.sh now provides a more + comprehensive framework for testing -m/-C feature interaction, + it doesn't exercise mixing them with anchors so the whole + relevant tests/foad1.sh test group is kept, notably to check + that grep doesn't crash when it is run. + +2005-11-17 Charles Levert + + On 2005-06-21, many changes were made that affected --color, + --only-matching, and --invert-match. Some of them introduced a + misunderstanding between the concepts of matched/non-matched and + selected/rejected lines. Furthermore, a few bugs with -v sneaked + in stemming from this. This set of changes aims to rectify most + of this situation. Some GREP_COLORS capabilities are also added + as a result of the clarification. (Further issues with -v/-o/-C + feature interaction still remain to be sorted out.) + + * src/grep.c: Rename/add global variables, macros, and capabilities: + SEP_CHAR_MATCH --> SEP_CHAR_SELECTED + SEP_CHAR_CONTEXT --> SEP_CHAR_REJECTED + SEP_STR_CHUNK --> SEP_STR_GROUP + grep_color --> selected_match_color + context_match_color + mlines_color --> selected_line_color + context_color --> context_line_color + "ml" --> "sl" + "mt" --> "mt" = "ms" + "mc" + --> "rv" (reverse "sl"/"cx" when -v) + * src/grep.c (color_cap_mt_fct, color_cap_rv_fct): New functions. + * src/grep.c (print_line_tail): Renamed color argument to line_color. + * src/grep.c (print_line_middle, prline): Revert part of the logic to + a pre-2005-06-21 one so that lines with matches have their matched + parts properly handled again ("m?" colors or --only-matching), + whether or not -v is specified. Whole line colors ("sl", "cx") + follow a selected / rejected(context) logic, as opposed to a + matched / non-matched one (unless "rv"). Matched text colors ("ms", + "mc") always follow a selected / rejected(context) logic, + regardless of "rv", because only matched lines use them anyway. + pr_line_middle() now takes additional line_color and match_color + arguments computed by prline() prior to calling that function. + The old logic was a buggy hybrid matched / rejected(context) one. + * src/grep.c (prpending, prtext, grepfile): Renamed macro invocations. + * src/grep.c (parse_grep_colors): Update top comment. + * src/grep.c (main): GREP_COLOR (singular) now sets both + selected_match_color and context_match_color. + +2005-11-16 Charles Levert + + * src/search.c (Pcompile): Clarify message for the -P option + not being supported so that users don't assume it's a run-time + problem, but know that it's a compile-time configuration choice. + Based on an idea by: Benno Schulenberg . + +2005-11-13 Charles Levert + + * tests/yesno.sh: New file. Test feature interaction + of -C, -v, -o, and -m. This reveals bugs, including some I + introduced on 2005-06-21, but also others. + * tests/Makefile.am (TESTS): Add yesno.sh. + * tests/Makefile.am (CLEANFILES): Add cspatfile and csinput, as + created by fmbtest.sh. Add yesno.txt, as created by yesno.sh. + +2005-11-11 Charles Levert + + * configure.in (ALL_LINGUAS): Add languages that were missing + from this variable (bg, ca, da, nb, tr), but that GNU grep supports + with a po/xx.po file. Reported by Tony Abou-Assaleh . + + * src/search.c (Pcompile): Abort in error if -P and multiple patterns + are specified, with an error message explaining the situation. + Fixing this won't be simple; the '\n' characters separating the + patterns cannot just be replaced by '|' to create an alternation as + back-references are assumed to be local to each individual pattern. + + * src/grep.c (parse_grep_colors, main): Replace all uses of + fprintf(stderr, _("%s: foo\n"), program_name, ...) with + error(0, 0, _("foo"), ...) for uniformization and simplification + of warning messages that will be up for localization. (My bad.) + +2005-11-10 Charles Levert + + The introduction of the --only-matching and --color GNU extensions + to grep added the requirement that each execute() implementation + not only be able to identify matching lines as a whole, but also + individual "exact" matches within a line known to be matching, + from leftmost to rightmost match, when the output from matching + lines is actually produced. The interface and implementations + of execute() were not up to it. This set of changes aims to + rectify that situation. Previously failing tests relative to + left anchors (^ and \<) and -w should now pass. This fixes + , + , + , + and possibly part of other, bigger, pending patches. The problem + was also compounded by the POSIX requirement to support a pattern + list instead of just an individual pattern (for -G and -E as well). + + * tests/foad1.sh: Test for increasing/decreasing-length word + matches, given pattern order, and leftmost/longest match. + * tests/fmbtest.sh: Modify test #6 according to new expectations. + Better document what tests #6 and #7 are actually for. Eliminate + test #5 in favor of bringing tests #6 and #7 within the F G E loop. + * src/grep.h (EXECUTE_ARGS): Change last argument from "int exact" + to "char const *start_ptr". Testing for "start_ptr" being non-NULL + retains the same semantics as testing for "exact" being non-zero. + * src/grep.c (print_line_middle): Call execute() with whole + buffer to work on, but using current position as start_ptr. + * src/grep.c (prpending, grepbuf): Call execute() with NULL + as start_ptr. + * src/search.c (EGexecute, Fexecute, Pexecute): When start_ptr is + non-NULL, return first match from it as an offset relative to buf. + * src/search.c (EGexecute): Consider all patterns if many and, + for an exact match, return the best one (leftmost, then longest). + Don't explore worst solutions, of course (branch and bound). + +2005-11-10 Charles Levert + + * src/grep.c (main): Fix a subtle memory allocation bug introduced + with the mb_icase_keys() function, which can call xrealloc() or + free() on keys, by making sure keys is always dynamically allocated. + +2005-11-09 Charles Levert + + * doc/grep.1, doc/grep.texi: Advise users to test for + "exit_status > 1" instead of "exit_status == 2" in order to + detect errors, for portability with other POSIX-compliant + implementations. + +2005-11-09 Charles Levert + + The following set of changes aims to make "egrep" and "fgrep" + minimal executable programs for legacy applications, instead of + shell scripts. This "fgrep" is much smaller than "grep". + This set of changes appears more daunting than it really is. + + * src/egrep.c, src/fgrep.c, src/esearch.c, src/fsearch.c: New files + that #define either EGREP_PROGRAM or FGREP_PROGRAM and #include + the corresponding generic (i.e., non e or f specific) *.c file. + * src/grepmat.c: Remove whole file. + * src/Makefile.am: Remove no-dependencies from AUTOMAKE_OPTIONS. + Add definitions to make "egrep" and "fgrep" specific standalone + executable programs that only use the source files they need. + Remove rules for "egrep" and "fgrep" shell scripts. + * src/grep.h: #define GREP_PROGRAM if both EGREP_PROGRAM and + FGREP_PROGRAM are #undef. Only declare matchers[] in this case + along with the compile_fp_t and execute_fp_t function pointers + typedefs, otherwise declare prototypes for straight compile() + and execute() functions for the specialized "egrep" and "fgrep" + programs. Remove the extern declaration for matcher. + Define COMPILE_RET, COMPILE_ARGS, EXECUTE_RET, EXECUTE_ARGS, + COMPILE_FCT, and EXECUTE_FCT helper preprocessor macros. + * src/grep.c (short_options, long_options, usage, main): Only + support -G, -E, -F, -P, and -X for GREP_PROGRAM, but not for + EGREP_PROGRAM or FGREP_PROGRAM. Customize usage messages. + * src/grep.c (set_limits): New function with unchanged code, + called from main(), because it shouldn't be in install_matcher() + since it was already matcher-independent. + * src/grep.c (matcher): Add as static, only for GREP_PROGRAM. + * src/grep.c (setmatcher, install_matcher): Only for GREP_PROGRAM. + * src/grep.c (main): Remove any tweaking and dependence on argv[0]. + * src/grep.c (print_line_middle, prpending, grepbuf, main): Call + compile() and execute() directly, not through a function + pointer dereferencing notation, so that it works with both + straight functions (in EGREP_PROGRAM and FGREP_PROGRAM) and + function pointers (in GREP_PROGRAM). + * src/search.c (, "dfa.h", dfa, pattern0, patterns, + pcount, dfaerror, kwset_exact_matches, kwsmusts): Only + include/declare/define if not FGREP_PROGRAM. + * src/search.c: Remove function prototypes for all functions + that are not used before their definition, since this is just + a hassle now with their varying names and conditional definition. + * src/search.c (GEAcompile): Rename from Ecompile(). Add new + syntax_bits argument/variable. Use as compile() for EGREP_PROGRAM. + Put in the needed RE_ICASE fix, albeit commented-out for now. + Make sure to free() modified word/line pattern after use, if any. + * src/search.c (Gcompile): Merge with GEAcompile() then remove. + * src/search.c (Gcompile, Acompile, Ecompile): New small functions + that call GEAcompile(), now that matcher is not an extern variable. + * src/search.c (GEAcompile, Gcompile, Acompile, Ecompile, + Fcompile, Pcompile, EGexecute, Fexecute, Pexecute, matchers): + Only define when needed according to *GREP_PROGRAM, and rename + to just compile() and execute() when appropriate. + * grep/bootstrap/Makefile.try: Similar changes. + +2005-11-08 Charles Levert + + * README.DOS, TODO, grep.spec, doc/grep.1, doc/grep.texi, + src/grep.h, po/da.po, po/nb.po, po/no.po, po/sv.po: + Replace all capitalized "Grep" by a lowercase "grep", except + in citations. Reported by Benno Schulenberg + from the + entry in the Debian bug tracker. + * doc/grep.1, doc/grep.texi: Explain that the "egrep" and "fgrep" + commands are deprecated and provided for historical applications. + Replace some "egrep" uses by "grep -E" to promote the newer usage. + Typeset "zgrep" as a command. Fix some spacing and punctuation bugs. + +2005-11-08 Julian Foad + + * doc/grep.texi: Rewrite a poorly written usage example about + back-references, and tweak another. New text by Benno Schulenberg. + +2005-11-04 Charles Levert + + * src/grep.c (mb_icase_keys): New function to properly lowercase + keys if match_icase. The problem was that some multi-octet + characters can get longer or shorter upon this conversion, so that + it cannot just naively be done in place on the same memory buffer. + * src/grep.c (main): Call mb_icase_keys (and remove in-line code). + + * tests/foad1.sh: Duplicate three "-o -b" tests for the "-F" + mode because it relies on a different code path that deserves + the same kind of testing. + +2005-09-27 Stepan Kasal + + * doc/grep.1: Fix a typo. + +2005-08-24 Charles Levert + + * src/grep.c (print_line_middle): In case of an empty match, + make minimal progress and continue instead of aborting process + of the remainder of the line, in case there's still an upcoming + non-empty match. + * tests/foad1.sh: Add two tests for this. + * doc/grep.texi, doc/grep.1: Document this behavior, since + --only-matching and --color are GNU extensions which are + otherwise unspecified by POSIX or other standards. + +2005-07-26 Charles Levert + + * tests/pcre.sh: New file.

This function had + a prototype to return such errors, but never did. + +2005-07-04 Charles Levert + + * src/kwset.c: Readability changes. + Replace uses of 0 for pointer values by NULL. + Generalize use of existing U() macro to whole file. + + * src/kwset.c (kwsprep): Use memset() and memcpy() when appropriate. + + * src/kwset.c (kwsprep): Move three variable declarations to + the single {}-block where they are used. + + * src/kwset.c (kwsprep): Optimize search for mind2 value by + starting from the end of the target[] array. + +2005-06-22 Charles Levert + + * grep/autogen.sh, grep/src/Makefile.am, grep/tests/backref.sh, + grep/tests/bre.sh, grep/tests/empty.sh, grep/tests/ere.sh, + grep/tests/file.sh, grep/tests/fmbtest.sh, grep/tests/foad1.sh, + grep/tests/khadafy.sh, grep/tests/options.sh, + grep/tests/spencer1.sh, grep/tests/spencer2.sh, + grep/tests/status.sh, grep/tests/warning.sh: As per autoconf's + "Portable Shell Programming" guidelines, replace all instances + of "#!/bin/sh" by "#! /bin/sh" (notice the space). + +2005-06-21 Charles Levert + + * src/grep.c (nlscan): Make this function more robust by removing + the undocumented assumption that its "lim" argument points + right after a line boundary. This will be used later to fix + --byte-offset's broken behavior. Patch #3769. + + * src/grep.c (main): Add a test to check if -o/--only-matching + and context lines are both specified and if so, set both context + specifications (before and after) to zero then print an explicit + warning to stderr explaining what was done and why (as opposed + to drastically aborting the process in error). Patch #3768. + Other code needs this zero setting to work correctly without + having to repeatedly test for this conflictual condition. + + * tests/foad1.sh: Add tests combining -o, -n/-b/-H, and -i, + since there are separate code paths for -i. Add tests combining + -o, -n/-b/-H, and -3, since any context line specification + should be ignored when combined with -o. + * src/grep.c (print_line_head): New function, culled off the + top content of prline(). Adds a guard against "lastnl" having + already reached "lim", which can happen when if the function + is called more than once per line. + * src/grep.c (prline): Now calls print_line_head(), not only at + the beginning to replace the moved code when -o is not + specified, but also for each match when -o is specified (two + code paths with this). Patch #3770, more or less. This makes + all tests combining -o and -n/-b/-H pass, which they didn't + before. Fixes bug #12727. + + * src/grep.c (SEP_CHAR_MATCH, SEP_CHAR_CONTEXT, SEP_STR_CHUNK): + New macros for ':', '-', and "--". Used throughout the file. + Will be used even more in upcoming updates, so good to have now. + + * src/grep.c: The new GREP_COLORS (plural) framework, only + partially used at this point to make for a simpler initial + patch in CVS. A subset of patch #3644 on Savannah. + * src/grep.c (color_cap_ne_fct, color_cap_xm_fct, print_filename, + print_sep, parse_grep_colors): New functions. + * src/grep.c (prtext, grepfile, main): Existing functions modified + to use the new framework. + * doc/grep.texi, doc/grep.1: Document GREP_COLORS. + + * src/grep.c: The new -T/--initial-tab framework, only + partially used at this point to make for a simpler initial + patch in CVS. A subset of patch #3644 on Savannah. + The option name/calling convention is the same as for GNU diff. + * doc/grep.texi, doc/grep.1: Document -T/--initial-tab. + + * src/grep.c (print_offset): Renamed print_offset_sep() to better + represent its new functionality; new calling convention. + * src/grep.c (print_offset, print_line_head): Use and implement + missing parts of the GREP_COLORS and -T/--initial-tab frameworks. + + * src/grep.c (print_line_middle, print_line_tail): New functions, + unused for now, intended to allow a simplifying rewrite of + prline(). Adding them first will make for cleaner CVS patches. + + * src/grep.c (prline): Simplifying rewrite using + print_line_middle() and print_line_tail().

This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell command './configure && make && make install' +should configure, build, and install this package. The following +more-detailed instructions are generic; see the 'README' file for +instructions specific to this package. Some packages provide this +'INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The 'configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a 'Makefile' in each directory of the package. +It may also create one or more '.h' files containing system-dependent +definitions. Finally, it creates a shell script 'config.status' that +you can run in the future to recreate the current configuration, and a +file 'config.log' containing compiler output (useful mainly for +debugging 'configure'). + + It can also use an optional file (typically called 'config.cache' and +enabled with '--cache-file=config.cache' or simply '-C') that saves the +results of its tests to speed up reconfiguring. Caching is disabled by +default to prevent problems with accidental use of stale cache files. + + If you need to do unusual things to compile the package, please try +to figure out how 'configure' could check whether to do them, and mail +diffs or instructions to the address given in the 'README' so they can +be considered for the next release. If you are using the cache, and at +some point 'config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file 'configure.ac' (or 'configure.in') is used to create +'configure' by a program called 'autoconf'. You need 'configure.ac' if +you want to change it or regenerate 'configure' using a newer version of +'autoconf'. + + The simplest way to compile this package is: + + 1. 'cd' to the directory containing the package's source code and type + './configure' to configure the package for your system. + + Running 'configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type 'make' to compile the package. + + 3. Optionally, type 'make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type 'make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the 'make install' phase executed with root + privileges. + + 5. Optionally, type 'make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior 'make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing 'make clean'. To also remove the + files that 'configure' created (so you can compile the package for + a different kind of computer), type 'make distclean'. There is + also a 'make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type 'make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide 'make + distcheck', which can by used by developers to test that all other + targets like 'make install' and 'make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the 'configure' script does not know about. Run './configure --help' +for details on some of the pertinent environment variables. + + You can give 'configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here is +an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU 'make'. 'cd' to the +directory where you want the object files and executables to go and run +the 'configure' script. 'configure' automatically checks for the source +code in the directory that 'configure' is in and in '..'. This is known +as a "VPATH" build. + + With a non-GNU 'make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use 'make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple '-arch' options to the +compiler but only a single '-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the 'lipo' tool if you have problems. + +Installation Names +================== + + By default, 'make install' installs the package's commands under +'/usr/local/bin', include files under '/usr/local/include', etc. You +can specify an installation prefix other than '/usr/local' by giving +'configure' the option '--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option '--exec-prefix=PREFIX' to 'configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like '--bindir=DIR' to specify different values for particular +kinds of files. Run 'configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the default +for these options is expressed in terms of '${prefix}', so that +specifying just '--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to 'configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +'make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, 'make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +'${prefix}'. Any directories that were specified during 'configure', +but not in terms of '${prefix}', must each be overridden at install time +for the entire installation to be relocated. The approach of makefile +variable overrides for each directory variable is required by the GNU +Coding Standards, and ideally causes no recompilation. However, some +platforms have known limitations with the semantics of shared libraries +that end up requiring recompilation when using this method, particularly +noticeable in packages that use GNU Libtool. + + The second method involves providing the 'DESTDIR' variable. For +example, 'make install DESTDIR=/alternate/directory' will prepend +'/alternate/directory' before all installation names. The approach of +'DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of '${prefix}' +at 'configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving 'configure' the +option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. + + Some packages pay attention to '--enable-FEATURE' options to +'configure', where FEATURE indicates an optional part of the package. +They may also pay attention to '--with-PACKAGE' options, where PACKAGE +is something like 'gnu-as' or 'x' (for the X Window System). The +'README' should mention any '--enable-' and '--with-' options that the +package recognizes. + + For packages that use the X Window System, 'configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the 'configure' options '--x-includes=DIR' and +'--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of 'make' will be. For these packages, running './configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with 'make V=1'; while running './configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with 'make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC +is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX 'make' updates targets which have the same timestamps as their +prerequisites, which makes it generally unusable when shipped generated +files such as 'configure' are involved. Use GNU 'make' instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its '' header file. The option '-nodtk' can be used as a +workaround. If GNU CC is not installed, it is therefore recommended to +try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put '/usr/ucb' early in your 'PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in '/usr/bin'. So, if you need '/usr/ucb' +in your 'PATH', put it _after_ '/usr/bin'. + + On Haiku, software installed for all users goes in '/boot/common', +not '/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features 'configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, 'configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +'--build=TYPE' option. TYPE can either be a short name for the system +type, such as 'sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file 'config.sub' for the possible values of each field. If +'config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option '--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with '--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for 'configure' scripts to share, +you can create a site shell script called 'config.site' that gives +default values for variables like 'CC', 'cache_file', and 'prefix'. +'configure' looks for 'PREFIX/share/config.site' if it exists, then +'PREFIX/etc/config.site' if it exists. Or, you can set the +'CONFIG_SITE' environment variable to the location of the site script. +A warning: not all 'configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to 'configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the 'configure' command line, using 'VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified 'gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an +Autoconf limitation. Until the limitation is lifted, you can use this +workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +'configure' Invocation +====================== + + 'configure' recognizes the following options to control how it +operates. + +'--help' +'-h' + Print a summary of all of the options to 'configure', and exit. + +'--help=short' +'--help=recursive' + Print a summary of the options unique to this package's + 'configure', and exit. The 'short' variant lists options used only + in the top level, while the 'recursive' variant lists options also + present in any nested packages. + +'--version' +'-V' + Print the version of Autoconf used to generate the 'configure' + script, and exit. + +'--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally 'config.cache'. FILE defaults to '/dev/null' to + disable caching. + +'--config-cache' +'-C' + Alias for '--cache-file=config.cache'. + +'--quiet' +'--silent' +'-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to '/dev/null' (any error + messages will still be shown). + +'--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + 'configure' can determine that directory automatically. + +'--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: for + more details, including other options available for fine-tuning the + installation locations. + +'--no-create' +'-n' + Run the configure checks, but stop before creating any output + files. + +'configure' also accepts some other, not widely useful, options.

[bug introduced in grep-2.6, which would + segfault, but 2.7 and 2.8 had no problem, and 2.9 through 2.14 would + hit a failed assertion. ] + + grep -F would get stuck in an infinite loop when given a search string + that is an invalid byte sequence in the current locale and that matches + the bytes of the input twice on a line. Now grep fails with exit status 1. + + grep -P could misbehave. While multi-byte mode is only supported by PCRE + with UTF-8 locales, grep did not activate it. This would cause failures + to match multibyte characters against some regular expressions, especially + those including the '.' or '\p' metacharacters. + +** New features + + grep -P can now use a just-in-time compiler to greatly speed up matches, + This feature is transparent to the user; no flag is required to enable + it. It is only available if the corresponding support in the PCRE + library is detected when grep is compiled. + + +* Noteworthy changes in release 2.14 (2012-08-20) [stable] + +** Bug fixes + + grep -i '^$' could exit 0 (i.e., report a match) in a multi-byte locale, + even though there was no match, and the command generated no output. + E.g., seq 2 | LC_ALL=en_US.utf8 grep -il '^$' would mistakenly print + "(standard input)". Related, seq 9 | LC_ALL=en_US.utf8 grep -in '^$' + would print "2:4:6:8:10:12:14:16" and exit 0. Now it prints nothing + and exits with status of 1. [bug introduced in grep-2.6] + + 'grep' no longer falsely reports text files as being binary on file + systems that compress contents or that store tiny contents in metadata. + + +* Noteworthy changes in release 2.13 (2012-07-04) [stable] + +** Bug fixes + + grep -i, in a multi-byte locale, when matching a line containing a character + like the UTF-8 Turkish I-with-dot (U+0130) (whose lower-case representation + occupies fewer bytes), would print an incomplete output line. + Similarly, with a matched line containing a character (e.g., the Latin + capital I in a Turkish UTF-8 locale), where the lower-case representation + occupies more bytes, grep could print garbage. + [bug introduced in grep-2.6] + + --include and --exclude can again be combined, and again apply to + the command line, e.g., "grep --include='*.[ch]' --exclude='system.h' + PATTERN *" again reads all *.c and *.h files except for system.h. + [bug introduced in grep-2.6] + +** New features + + 'grep' without -z now treats a sparse file as binary, if it can + easily determine that the file is sparse. + +** Dropped features + + Bootstrapping with Makefile.boot has been broken since grep 2.6, + and was removed. + + +* Noteworthy changes in release 2.12 (2012-04-23) [stable] + +** Bug fixes + + "echo P|grep --devices=skip P" once again prints P, as it did in 2.10 + [bug introduced in grep-2.11] + + grep no longer segfaults with -r --exclude-dir and no file operand. + I.e., ":|grep -r --exclude-dir=D PAT" would segfault. + [bug introduced in grep-2.11] + + Recursive grep now uses fts for directory traversal, so it can + handle much-larger directories without reporting things like "File + name too long", and it can run much faster when dealing with large + directory hierarchies.

Also, grep -c's counts are now + limited by the type 'intmax_t' (typically less than 2**63) rather + than 'int' (typically less than 2**31). + + grep no longer silently suppresses errors when reading a directory + as if it were a text file. For example, "grep x ." now reports a + read error on most systems; formerly, it ignored the error. + [bug introduced in grep-2.5] + + grep now exits with status 2 if a directory loop is found, + instead of possibly exiting with status 0 or 1. + [bug introduced in grep-2.3] + + The -s option now suppresses certain input error diagnostics that it + formerly failed to suppress. These include errors when closing the + input, when lseeking the input, and when the input is also the output. + [bug introduced in grep-2.4] + + On POSIX systems, commands like "grep PAT < FILE >> FILE" + now report an error instead of looping. + [bug present since "the beginning"] + + The --include, --exclude, and --exclude-dir options now handle + command-line arguments more consistently. --include and --exclude + apply only to non-directories and --exclude-dir applies only to + directories. "-" (standard input) is never excluded, since it is + not a file name. + [bug introduced in grep-2.5] + + grep no longer rejects "grep -qr . > out", i.e., when run with -q + and an input file is the same as the output file, since with -q + grep generates no output, so there is no risk of infinite loop or + of an output-affecting race condition. Thus, the use of the following + options also disables the input-equals-output failure: + --max-count=N (-m) (for N >= 2) + --files-with-matches (-l) + --files-without-match (-L) + [bug introduced in grep-2.10] + + grep no longer emits an error message and quits on MS-Windows when + invoked with the -r option. + + grep no longer misinterprets some alternations involving anchors + (^, $, \< \> \B, \b). For example, grep -E "(^|\B)a" no + longer reports a match for the string "x a". + [bug present since "the beginning"] + +** New features + + If no file operand is given, and a command-line -r or equivalent + option is given, grep now searches the working directory. Formerly + grep ignored the -r and searched standard input nonrecursively. + An -r found in GREP_OPTIONS does not have this new effect. + + grep now supports color highlighting of matches on MS-Windows. + +** Changes in behavior + + Use of the --mmap option now elicits a warning. It has been a no-op + since March of 2010. + + grep no longer diagnoses write errors repeatedly; it exits after + diagnosing the first write error.

This is more consistent with programs that + (e.g.) ignore errors in termcap entries. + +* Noteworthy changes in release 2.10 (2011-11-16) [stable] + +** Bug fixes + + grep no longer mishandles high-bit-set pattern bytes on systems + where "char" is a signed type. [bug appears to affect only MS-Windows] + + On POSIX systems, grep now rejects a command like "grep -r pattern . > out", + in which the output file is also one of the inputs, + because it can result in an "infinite" disk-filling loop. + [bug present since "the beginning"] + +** Build-related + + "make dist" no longer builds .tar.gz files. + xz is portable enough and in wide-enough use that distributing + only .tar.xz files is enough. + + +* Noteworthy changes in release 2.9 (2011-06-21) [stable] + +** Bug fixes + + grep no longer clobbers heap for an ERE like '(^| )*( |$)' + [bug introduced in grep-2.6] + + grep is faster on regular expressions that match multibyte characters + in brackets (such as '[áéíóú]'). + + echo c|grep '[c]' would fail for any c in 0x80..0xff, with a uni-byte + encoding for which the byte-to-wide-char mapping is nontrivial.

This is consistent + with the behavior of options -A/-B/-C. + + Two new command-line options, --group-separator=ARGUMENT and + --no-group-separator, enable further customization of the output + when -A, -B or -C is being used. + +** Other changes + + egrep accepts the -E option and fgrep accepts the -F option.

This is useful, for example, to extract + IP addresses from log files. + + - i18n bug fixed ([A-Z0-9] wouldn't match A in locales other than C on + systems using recent glibc builds + + - GNU grep can now be built with autoconf 2.52. + + - The new option --devices controls how grep handles device files.

There is a noticeable + slow down when forcing line buffering. + + - Back-references are now local to the regex. + grep -e '\(a\)\1' -e '\(b\)\1' + The last backref \1 in the second expression refer to \(b\) + + - The new option --include=PATTERN will search only matching files + when recursing in directories + + - The new option --exclude=PATTERN will skip matching files when + recursing in directories. + + - The new option --color will use the environment variable GREP_COLOR + (default is red) to highlight the matching string. + --color takes an optional argument specifying when to colorize a line: + --color=always, --color=tty, --color=never + + - The following changes are for POSIX conformance: + + . The -q or --quiet or --silent option now causes grep to exit + with zero status when a input line is selected, even if an error + also occurs. + + . The -s or --no-messages option no longer affects the exit status. + + . Bracket regular expressions like [a-z] are now locale-dependent. + For example, many locales sort characters in dictionary order, + and in these locales the regular expression [a-d] is not + equivalent to [abcd]; it might be equivalent to [aBbCcDd], for + example. To obtain the traditional interpretation of bracket + expressions, you can use the C locale by setting the LC_ALL + environment variable to the value "C". + + - The -C or --context option now requires an argument, partly for + consistency, and partly because POSIX recommends against + optional arguments. + + - The new -P or --perl-regexp option tells grep to interpret the pattern as + a Perl regular expression. + + - The new option --max-count=num makes grep stop reading a file after num + matching lines. + New option -m; equivalent to --max-count. + + - Translations for bg, ca, da, nb and tr have been added. + +Version 2.4.2 + + - Added more check in configure to default the grep-${version}/src/regex.c + instead of the one in GNU Lib C. + +Version 2.4.1 + + - If the final byte of an input file is not a newline, grep now silently + supplies one. + + - The new option --binary-files=TYPE makes grep assume that a binary input + file is of type TYPE. + --binary-files='binary' (the default) outputs a 1-line summary of matches. + --binary-files='without-match' assumes binary files do not match. + --binary-files='text' treats binary files as text + (equivalent to the -a or --text option). + + - New option -I; equivalent to --binary-files='without-match'. + +Version 2.4: + + - egrep is now equivalent to 'grep -E' as required by POSIX, + removing a longstanding source of confusion and incompatibility. + 'grep' is now more forgiving about stray '{'s, for backward + compatibility with traditional egrep. + + - The lower bound of an interval is not optional. + You must use an explicit zero, e.g. 'x{0,10}' instead of 'x{,10}'. + (The old documentation incorrectly claimed that it was optional.) + + - The --revert-match option has been renamed to --invert-match. + + - The --fixed-regexp option has been renamed to --fixed-strings. + + - New option -H or --with-filename. + + - New option --mmap. By default, GNU grep now uses read instead of mmap. + This is faster on some hosts, and is safer on all. + + - The new option -z or --null-data causes 'grep' to treat a zero byte + (the ASCII NUL character) as a line terminator in input data, and + to treat newlines as ordinary data. + + - The new option -Z or --null causes 'grep' to output a zero byte + instead of the normal separator after a file name. + + - These two options can be used with commands like 'find -print0', + 'perl -0', 'sort -z', and 'xargs -0' to process arbitrary file names, + even those that contain newlines. + + - The environment variable GREP_OPTIONS specifies default options; + e.g. GREP_OPTIONS='--directories=skip' reestablishes grep 2.1's + behavior of silently skipping directories. + + - You can specify a matcher multiple times without error, e.g. + 'grep -E -E' or 'fgrep -F'. It is still an error to specify + conflicting matchers. + + - -u and -U are now allowed on non-DOS hosts, and have no effect. + + - Modifications of the tests scripts to go around the "Broken Pipe" + errors from bash. See Bash FAQ. + + - New option -r or --recursive or --directories=recurse. + (This option was also in grep 2.3, but wasn't announced here.) + + - --without-included-regex disable, was causing bogus reports .i.e + doing more harm then good. + +Version 2.3: + + - When searching a binary file FOO, grep now just reports + "Binary file FOO matches" instead of outputting binary data. + This is typically more useful than the old behavior, + and it is also more consistent with other utilities like 'diff'. + A file is considered to be binary if it contains a NUL (i.e. zero) byte. + + The new -a or --text option causes 'grep' to assume that all + input is text. (This option has the same meaning as with 'diff'.) + Use it if you want binary data in your output. + + - 'grep' now searches directories just like ordinary files; it no longer + silently skips directories. This is the traditional behavior of + Unix text utilities (in particular, of traditional 'grep'). + Hence 'grep PATTERN DIRECTORY' should report + "grep: DIRECTORY: Is a directory" on hosts where the operating system + does not permit programs to read directories directly, and + "grep: DIRECTORY: Binary file matches" (or nothing) otherwise. + + The new -d ACTION or --directories=ACTION option affects directory handling. + '-d skip' causes 'grep' to silently skip directories, as in grep 2.1; + '-d read' (the default) causes 'grep' to read directories if possible, + as in earlier versions of grep. + + - The MS-DOS and Microsoft Windows ports now behave identically to the + GNU and Unix ports with respect to binary files and directories. + +Version 2.2: + +Bug fix release. + + - Status error number fix. + - Skipping directories removed. + - Many typos fix. + - -f /dev/null fix(not to consider as an empty pattern). + - Checks for wctype/wchar. + - -E was using the wrong matcher fix. + - bug in regex char class fix + - Fixes for DJGPP + +Version 2.1: + +This is a bug fix release(see Changelog) i.e. no new features. + + - More compliance to GNU standard. + - Long options. + - Internationalization. + - Use automake/autoconf. + - Directory hierarchy change. + - Sigvec with -e on Linux corrected. + - Sigvec with -f on Linux corrected. + - Sigvec with the mmap() corrected. + - Bug in kwset corrected. + - -q, -L and -l stop on first match. + - New and improve regex.[ch] from Ulrich Drepper. + - New and improve dfa.[ch] from Arnold Robbins. + - Prototypes for over zealous C compiler. + - Not scanning a file, if it's a directory + (cause problems on Sun). + - Ported to MS-DOS/MS-Windows with DJGPP tools. + +See Changelog for the full story and proper credits. + +Version 2.0: + +The most important user visible change is that egrep and fgrep have +disappeared as separate programs into the single grep program mandated +by POSIX 1003.2. New options -G, -E, and -F have been added, +selecting grep, egrep, and fgrep behavior respectively. For +compatibility with historical practice, hard links named egrep and +fgrep are also provided. See the manual page for details. + +In addition, the regular expression facilities described in Posix +draft 11.2 are now supported, except for internationalization features +related to locale-dependent collating sequence information. + +There is a new option, -L, which is like -l except it lists +files which don't contain matches. The reason this option was +added is because '-l -v' doesn't do what you expect. + +Performance has been improved; the amount of improvement is platform +dependent, but (for example) grep 2.0 typically runs at least 30% faster +than grep 1.6 on a DECstation using the MIPS compiler. Where possible, +grep now uses mmap() for file input; on a Sun 4 running SunOS 4.1 this +may cut system time by as much as half, for a total reduction in running +time by nearly 50%. On machines that don't use mmap(), the buffering +code has been rewritten to choose more favorable alignments and buffer +sizes for read(). + +Portability has been substantially cleaned up, and an automatic +configure script is now provided. + +The internals have changed in ways too numerous to mention. +People brave enough to reuse the DFA matcher in other programs +will now have their bravery amply "rewarded", for the interface +to that file has been completely changed. Some changes were +necessary to track the evolution of the regex package, and since +I was changing it anyway I decided to do a general cleanup. + +======================================================================== +Copyright (C) 1992, 1997-2002, 2004-2021 Free Software Foundation, Inc. + + Copying and distribution of this file, with or without modification, + are permitted in any medium without royalty provided the copyright + notice and this notice are preserved. + +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, with no Front-Cover Texts, and with no Back-Cover +Texts.

Extend this support to non-glibc +platforms, where --with-included-regex is in effect, by modifying the +included version of the regex code to defer to the native version when +handling [= =] and [. .]. + +For Unicode, interesting things to check include the Unicode Standard + and the Unicode Technical +Standard #18 ( “Unicode Regular +Expressions”). Talk to Bruno Haible who’s maintaining GNU libunistring. +See also Unicode Standard Annex #15 ( +“Unicode Normalization Forms”), already implemented by GNU libunistring. + +In particular, --ignore-case needs to be evaluated against the standards. +We may want to deviate from POSIX if Unicode provides better or clearer +semantics. + +POSIX and --ignore-case +----------------------- + +For this issue, interesting things to check in POSIX include the +Open Group Base Specifications, Chapter “Regular Expressions”, in +particular Section “Regular Expression General Requirements” and its +paragraph about caseless matching (this may not have been fully +thought through and that this text may be self-contradicting +[specifically: “of either data or patterns” versus all the rest]). +See: + +http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html#tag_09_02 + +In particular, consider the following with POSIX’s approach to case +folding in mind. Assume a non-Turkic locale with a character +repertoire reduced to the following various forms of “LATIN LETTER I”: + + 0049;LATIN CAPITAL LETTER I;Lu;0;L;;;;;N;;;;0069; + 0069;LATIN SMALL LETTER I;Ll;0;L;;;;;N;;;0049;;0049 + 0130;LATIN CAPITAL LETTER I WITH DOT ABOVE;Lu;0;L;0049 0307;;;;N;\ + LATIN CAPITAL LETTER I DOT;;;0069; + 0131;LATIN SMALL LETTER DOTLESS I;Ll;0;L;;;;;N;;;0049;;0049 + +UTF-8 octet lengths differ between U+0049 (0x49) and U+0069 (0x69) +versus U+0130 (0xC4 0xB0) and U+0131 (0xC4 0xB1). This implies that +whole UTF-8 strings cannot be case-converted in place, using the same +memory buffer, and that the needed octet-size of the new buffer cannot +merely be guessed (although there’s a simple upper bound of five times +the size of the input, as the longest UTF-8 encoding of any character +is five bytes). + +We have + + lc(I) = i, uc(I) = I + lc(i) = i, uc(i) = I + lc(İ) = i, uc(İ) = İ + lc(ı) = ı, uc(ı) = I + +where lc() and uc() denote lower-case and upper-case conversions. + +There are several candidate --ignore-case logics. Using the + + if (lc(input_wchar) == lc(pattern_wchar)) + +logic leads to the following matches: + + \in I i İ ı + pat\ ---------- + I | Y Y Y n + i | Y Y Y n + İ | Y Y Y n + ı | n n n Y + +There is a lack of symmetry between CAPITAL and SMALL LETTERs with +this. Using the + + if (uc(input_wchar) == uc(pattern_wchar)) + +logic (which is what GNU grep currently does although this is not +documented or guaranteed in the future), leads to the following +matches: + + \in I i İ ı + pat\ ---------- + I | Y Y n Y + i | Y Y n Y + İ | n n Y n + ı | Y Y n Y + +There is a lack of symmetry between CAPITAL and SMALL LETTERs with +this. + +Using the + + if (lc(input_wchar) == lc(pattern_wchar) + || uc(input_wchar) == uc(pattern_wchar)) + +logic leads to the following matches: + + \in I i İ ı + pat\ ---------- + I | Y Y Y Y + i | Y Y Y Y + İ | Y Y Y n + ı | Y Y n Y + +There is some elegance and symmetry with this. But there are +potentially two conversions to be made per input character. If the +pattern is pre-converted, two copies of it need to be kept and used in +a mutually coherent fashion. + +Using the + + if (input_wchar == pattern_wchar + || lc(input_wchar) == pattern_wchar + || uc(input_wchar) == pattern_wchar) + +logic (a plausible interpretation of POSIX) leads to the following +matches: + + \in I i İ ı + pat\ ---------- + I | Y Y n Y + i | Y Y Y n + İ | n n Y n + ı | n n n Y + +There is a different CAPITAL/SMALL symmetry with this. But there’s +also a loss of pattern/input symmetry that’s unique to it. Also there +are potentially two conversions to be made per input character. + +Using the + + if (lc(uc(input_wchar)) == lc(uc(pattern_wchar))) + +logic leads to the following matches: + + \in I i İ ı + pat\ ---------- + I | Y Y Y Y + i | Y Y Y Y + İ | Y Y Y Y + ı | Y Y Y Y + +This shows total symmetry and transitivity (at least in this example +analysis). There are two conversions to be made per input character, +but support could be added for having a single straight mapping +performing a composition of the two conversions. + +Any optimization in the implementation of each logic must not change +its basic semantic. + + +Unicode and --ignore-case +------------------------- + +For this issue, interesting things to check in Unicode include: + + - The Unicode Standard, Chapter 3 + ( + “Conformance”), Section 3.13 (“Default Case Algorithms”) and the + toCasefold() case conversion operation. + + - The Unicode Standard, Chapter 4 + ( + “Character Properties”), Section 4.2 (“Case”) and + the + SpecialCasing.txt and + + CaseFolding.txt files. + + - The Unicode Standard, Chapter 5 + ( + “Implementation Guidelines”), Section 5.18 (“Case Mappings”), + Subsection “Caseless Matching”. + + - The Unicode case charts . + +Unicode uses the + + if (toCasefold(input_wchar_string) == toCasefold(pattern_wchar_string)) + +logic for caseless matching. Consider the “LATIN LETTER I” example +mentioned above. In a non-Turkic locale, simple case folding yields + + toCasefold_simple(U+0049) = U+0069 + toCasefold_simple(U+0069) = U+0069 + toCasefold_simple(U+0130) = U+0130 + toCasefold_simple(U+0131) = U+0131 + +which leads to the following matches: + + \in I i İ ı + pat\ ---------- + I | Y Y n n + i | Y Y n n + İ | n n Y n + ı | n n n Y + +This is different from anything so far! + +In a non-Turkic locale, full case folding yields + + toCasefold_full(U+0049) = U+0069 + toCasefold_full(U+0069) = U+0069 + toCasefold_full(U+0130) = + toCasefold_full(U+0131) = U+0131 + +with + + 0307;COMBINING DOT ABOVE;Mn;230;NSM;;;;;N;NON-SPACING DOT ABOVE;;;; + +which leads to the following matches: + + \in I i İ ı + pat\ ---------- + I | Y Y * n + i | Y Y * n + İ | n n Y n + ı | n n n Y + +This is just sad! + +Having toCasefold(U+0131), simple or full, map to itself instead of +U+0069 is in contradiction with the rules of Section 5.18 of the +Unicode Standard since toUpperCase(U+0131) is U+0049. Same thing for +toCasefold_simple(U+0130) since toLowerCase(U+0131) is U+0069. The +justification for the weird toCasefold_full(U+0130) mapping is +unknown; it doesn’t even make sense to add a dot (U+0307) to a letter +that already has one (U+0069). It would have been so simple to put +them all in the same equivalence class! + +Otherwise, also consider the following problem with Unicode’s approach +on case folding in mind. Assume that we want to perform + + echo 'AßBC' | grep -i 'Sb' + +which corresponds to + + input: U+0041 U+00DF U+0042 U+0043 U+000A + pattern: U+0053 U+0062 + +Following CaseFolding.txt, applying the toCasefold() transformation to +these yields + + input: U+0061 U+0073 U+0073 U+0062 U+0063 U+000A + pattern: U+0073 U+0062 + +so, according to this approach, the input should match the pattern. +As long as the original input line is to be reported to the user as a +whole, there is no problem (from the user’s point-of-view; +implementation is complicated by this). + +However, consider both these GNU extensions: + + echo 'AßBC' | grep -i --only-matching 'Sb' + echo 'AßBC' | grep -i --color=always 'Sb' + +What is to be reported in these cases, since the match begins in the +*middle* of the original input character ‘ß’? + +Unicode’s toCasefold() cannot be implemented in terms of POSIX’s +towctrans() since that can only return a single wint_t value per input +wint_t value. diff --git a/src/grep/aclocal.m4 b/src/grep/aclocal.m4 new file mode 100644 index 0000000..f424ccf --- /dev/null +++ b/src/grep/aclocal.m4 @@ -0,0 +1,1381 @@ +# generated automatically by aclocal 1.16d -*- Autoconf -*- + +# Copyright (C) 1996-2021 Free Software Foundation, Inc. + +# This file is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) +m4_ifndef([AC_AUTOCONF_VERSION], + [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl +m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.71],, +[m4_warning([this file was generated for autoconf 2.71. +You have another version of autoconf.

It is the first copyright statement that meets all of the +# following conditions. Subsequent copyright statements are +# ignored. +# 2. Its format is "Copyright (C)", then a list of copyright years, +# and then the name of the copyright holder. +# 3. The "(C)" takes one of the following forms or is omitted +# entirely: +# +# A. (C) +# B. (c) +# C. @copyright{} +# D. © +# E. © +# +# 4. The "Copyright" appears at the beginning of a line, except that it +# may be prefixed by any sequence (e.g., a comment) of no more than +# 5 characters -- including white space. +# 5. Iff such a prefix is present, the same prefix appears at the +# beginning of each remaining line within the FSF copyright +# statement.

The replacement of "*" +# by " " is consistent throughout all subsequent lines. +# 6. Blank lines, even if preceded by the prefix, do not appear +# within the FSF copyright statement. +# 7. Each copyright year is 2 or 4 digits, and years are separated by +# commas, "-", or "--". Whitespace may appear after commas. +# +# Environment variables: +# +# 1. If UPDATE_COPYRIGHT_FORCE=1, a recognized FSF copyright statement +# is reformatted even if it does not need updating for the new +# year. If unset or set to 0, only updated FSF copyright +# statements are reformatted. +# 2. If UPDATE_COPYRIGHT_USE_INTERVALS=1, every series of consecutive +# copyright years (such as 90, 1991, 1992-2007, 2008) in a +# reformatted FSF copyright statement is collapsed to a single +# interval (such as 1990-2008).

+Copyright @copyright{} 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc. +@uref{https://fsf.org/} + +Everyone is permitted to copy and distribute verbatim copies +of this license document, but changing it is not allowed. +@end display + +@enumerate 0 +@item +PREAMBLE + +The purpose of this License is to make a manual, textbook, or other +functional and useful document @dfn{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. + +@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 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''.

+differences for basic regular expressions are summarized afterwards. +Perl-compatible regular expressions give additional functionality, and are +documented in B<pcresyntax>(3) and B<pcrepattern>(3), but work only if +PCRE support is enabled. +.PP +The fundamental building blocks are the regular expressions +that match a single character. +Most characters, including all letters and digits, +are regular expressions that match themselves. +Any meta-character with special meaning +may be quoted by preceding it with a backslash. +.PP +The period +.B .\& +matches any single character. +It is unspecified whether it matches an encoding error. +.SS "Character Classes and Bracket Expressions" +A +.I "bracket expression" +is a list of characters enclosed by +.B [ +and +.BR ] . +It matches any single +character in that list. +If the first character of the list +is the caret +.B ^ +then it matches any character +.I not +in the list; it is unspecified whether it matches an encoding error. +For example, the regular expression +.B [0123456789] +matches any single digit. +.PP +Within a bracket expression, a +.I "range expression" +consists of two characters separated by a hyphen. +It matches any single character that sorts between the two characters, +inclusive, using the locale's collating sequence and character set. +For example, in the default C locale, +.B [a\-d] +is equivalent to +.BR [abcd] . +Many locales sort characters in dictionary order, and in these locales +.B [a\-d] +is typically not equivalent to +.BR [abcd] ; +it might be equivalent to +.BR [aBbCcDd] , +for example. +To obtain the traditional interpretation of bracket expressions, +you can use the C locale by setting the +.B LC_ALL +environment variable to the value +.BR C . +.PP +Finally, certain named classes of characters are predefined within +bracket expressions, as follows. +Their names are self explanatory, and they are +.BR [:alnum:] , +.BR [:alpha:] , +.BR [:blank:] , +.BR [:cntrl:] , +.BR [:digit:] , +.BR [:graph:] , +.BR [:lower:] , +.BR [:print:] , +.BR [:punct:] , +.BR [:space:] , +.BR [:upper:] , +and +.BR [:xdigit:] . +For example, +.B [[:alnum:]] +means the character class of numbers and +letters in the current locale. +In the C locale and ASCII +character set encoding, this is the same as +.BR [0\-9A\-Za\-z] . +(Note that the brackets in these class names are part of the symbolic +names, and must be included in addition to the brackets delimiting +the bracket expression.) +Most meta-characters lose their special meaning inside bracket expressions. +To include a literal +.B ] +place it first in the list. +Similarly, to include a literal +.B ^ +place it anywhere but first. +Finally, to include a literal +.B \- +place it last. +.SS Anchoring +The caret +.B ^ +and the dollar sign +.B $ +are meta-characters that respectively match the empty string at the +beginning and end of a line. +.SS "The Backslash Character and Special Expressions" +The symbols +.B \e< +and +.B \e> +respectively match the empty string at the beginning and end of a word. +The symbol +.B \eb +matches the empty string at the edge of a word, +and +.B \eB +matches the empty string provided it's +.I not +at the edge of a word. +The symbol +.B \ew +is a synonym for +.B [_[:alnum:]] +and +.B \eW +is a synonym for +.BR [^_[:alnum:]] . +.SS Repetition +A regular expression may be followed by one of several repetition operators: +.PD 0 +.TP +.B ? +The preceding item is optional and matched at most once. +.TP +.B * +The preceding item will be matched zero or more times. +.TP +.B + +The preceding item will be matched one or more times. +.TP +.BI { n } +The preceding item is matched exactly +.I n +times. +.TP +.BI { n ,} +The preceding item is matched +.I n +or more times. +.TP +.BI {, m } +The preceding item is matched at most +.I m +times. +This is a GNU extension. +.TP +.BI { n , m } +The preceding item is matched at least +.I n +times, but not more than +.I m +times. +.PD +.SS Concatenation +Two regular expressions may be concatenated; the resulting +regular expression matches any string formed by concatenating +two substrings that respectively match the concatenated +expressions. +.SS Alternation +Two regular expressions may be joined by the infix operator +.BR | ; +the resulting regular expression matches any string matching +either alternate expression. +.SS Precedence +Repetition takes precedence over concatenation, which in turn +takes precedence over alternation. +A whole expression may be enclosed in parentheses +to override these precedence rules and form a subexpression. +.SS "Back-references and Subexpressions" +The back-reference +.BI \e n\c +\&, where +.I n +is a single digit, matches the substring +previously matched by the +.IR n th +parenthesized subexpression of the regular expression. +.SS "Basic vs Extended Regular Expressions" +In basic regular expressions the meta-characters +.BR ? , +.BR + , +.BR { , +.BR | , +.BR ( , +and +.BR ) +lose their special meaning; instead use the backslashed +versions +.BR \e? , +.BR \e+ , +.BR \e{ , +.BR \e| , +.BR \e( , +and +.BR \e) . +. +.SH "EXIT STATUS" +Normally the exit status is 0 if a line is selected, 1 if no lines +were selected, and 2 if an error occurred. However, if the +.B \-q +or +.B \-\^\-quiet +or +.B \-\^\-silent +is used and a line is selected, the exit status is 0 even if an error +occurred. +. +.SH ENVIRONMENT +The behavior of +.B grep +is affected by the following environment variables. +.PP +The locale for category +.BI LC_ foo +is specified by examining the three environment variables +.BR LC_ALL , +.BR LC_\fIfoo\fP , +.BR LANG , +in that order. +The first of these variables that is set specifies the locale. +For example, if +.B LC_ALL +is not set, but +.B LC_MESSAGES +is set to +.BR pt_BR , +then the Brazilian Portuguese locale is used for the +.B LC_MESSAGES +category. +The C locale is used if none of these environment variables are set, +if the locale catalog is not installed, or if +.B grep +was not compiled with national language support (NLS). +The shell command +.B "locale \-a" +lists locales that are currently available. +.TP +.B GREP_COLOR +This variable specifies the color used to highlight matched (non-empty) text. +It is deprecated in favor of +.BR GREP_COLORS , +but still supported. +The +.BR mt , +.BR ms , +and +.B mc +capabilities of +.B GREP_COLORS +have priority over it. +It can only specify the color used to highlight +the matching non-empty text in any matching line +(a selected line when the +.B \-v +command-line option is omitted, +or a context line when +.B \-v +is specified). +The default is +.BR 01;31 , +which means a bold red foreground text on the terminal's default background. +.TP +.B GREP_COLORS +Specifies the colors and other attributes +used to highlight various parts of the output. +Its value is a colon-separated list of capabilities +that defaults to +.B ms=01;31:mc=01;31:sl=:cx=:fn=35:ln=32:bn=32:se=36 +with the +.B rv +and +.B ne +boolean capabilities omitted (i.e., false). +Supported capabilities are as follows. +.RS +.TP +.B sl= +SGR substring for whole selected lines +(i.e., +matching lines when the +.B \-v +command-line option is omitted, +or non-matching lines when +.B \-v +is specified). +If however the boolean +.B rv +capability +and the +.B \-v +command-line option are both specified, +it applies to context matching lines instead. +The

when the +.B \-v +command-line option is omitted, +or a context line when +.B \-v +is specified). +Setting this is equivalent to setting both +.B ms= +and +.B mc= +at once to the same value. +The

background. +.TP +.B se=36 +SGR substring for separators that are inserted +between selected line fields +.RB ( : ), +between context line fields, +.RB ( \- ), +and between groups of adjacent lines when nonzero context is specified +.RB ( \-\^\- ). +The default is a cyan text foreground over the terminal's default background. +.TP +.B ne +Boolean value that prevents clearing to the end of line +using Erase in Line (EL) to Right +.RB ( \e33[K ) +each time a colorized item ends. +This is needed on terminals on which EL is not supported. +It is otherwise useful on terminals +for which the +.B back_color_erase +.RB ( bce ) +boolean terminfo capability does not apply, +when the chosen highlight colors do not affect the background, +or when EL is too slow or causes too much flicker. +The default is false (i.e., the capability is omitted). +.PP +Note that boolean capabilities have no +.BR = .\|.\|.\& +part. +They are omitted (i.e., false) by default and become true when specified. +.PP +See the Select Graphic Rendition (SGR) section +in the documentation of the text terminal that is used +for permitted values and their meaning as character attributes. +These substring values are integers in decimal representation +and can be concatenated with semicolons. +.B grep +takes care of assembling the result +into a complete SGR sequence +.RB ( \e33[ .\|.\|. m ). +Common values to concatenate include +.B 1 +for bold, +.B 4 +for underline, +.B 5 +for blink, +.B 7 +for inverse, +.B 39 +for default foreground color, +.B 30 +to +.B 37 +for foreground colors, +.B 90 +to +.B 97 +for

100 +to +.B 107 +for 16-color mode background colors, and +.B 48;5;0 +to +.B 48;5;255 +for 88-color and 256-color modes background colors. +.RE +.TP +\fBLC_ALL\fP, \fBLC_COLLATE\fP, \fBLANG\fP +These variables specify the locale for the +.B LC_COLLATE +category, +which determines the collating sequence +used to interpret range expressions like +.BR [a\-z] . +.TP +\fBLC_ALL\fP, \fBLC_CTYPE\fP, \fBLANG\fP +These variables specify the locale for the +.B LC_CTYPE +category, +which determines the type of characters, +e.g., which characters are whitespace. +This category also determines the character encoding, that is, whether +text is encoded in UTF-8, ASCII, or some other encoding. In the C or +POSIX locale, all characters are encoded as a single byte and every +byte is a valid character. +.TP +\fBLC_ALL\fP, \fBLC_MESSAGES\fP, \fBLANG\fP +These variables specify the locale for the +.B LC_MESSAGES +category, +which determines the language that +.B grep +uses for messages. +The default C locale uses American English messages. +.TP +.B POSIXLY_CORRECT +If set, +.B grep +behaves as POSIX requires; otherwise, +.B grep +behaves more like other GNU programs. +POSIX requires that options that follow file names must be +treated as file names; by default, such options are permuted to the +front of the operand list and are treated as options. +Also, POSIX requires that unrecognized options be diagnosed as +\*(lqillegal\*(rq, but since they are not really against the law the default +is to diagnose them as \*(lqinvalid\*(rq. +.B POSIXLY_CORRECT +also disables \fB_\fP\fIN\fP\fB_GNU_nonoption_argv_flags_\fP, +described below. +.TP +\fB_\fP\fIN\fP\fB_GNU_nonoption_argv_flags_\fP +(Here +.I N +is +.BR grep 's +numeric process ID.)

If the final byte of an input file +is not a newline, ‘grep’ silently supplies one. Since newline is also a +separator for the list of patterns, there is no way to match newline +characters in a text. + + +File: grep.info, Node: Invoking, Next: Regular Expressions, Prev: Introduction, Up: Top + +2 Invoking ‘grep’ +***************** + +The general synopsis of the ‘grep’ command line is + + grep [OPTION...] [PATTERNS] [FILE...] + +There can be zero or more OPTION arguments, and zero or more FILE +arguments.

Long option names are always a GNU extension, even for +options that are from POSIX specifications. Options that are specified +by POSIX, under their short names, are explicitly marked as such to +facilitate POSIX-portable programming.

If this option is used + multiple times or is combined with the ‘-f’ (‘--file’) option, + search for all patterns given. Typically PATTERNS should be quoted + when ‘grep’ is used in a shell command. (‘-e’ is specified by + POSIX.) + +‘-f FILE’ +‘--file=FILE’ + Obtain patterns from FILE, one per line. If this option is used + multiple times or is combined with the ‘-e’ (‘--regexp’) option, + search for all patterns given. The empty file contains zero + patterns, and therefore matches nothing. (‘-f’ is specified by + POSIX.) + +‘-i’ +‘-y’ +‘--ignore-case’ + Ignore case distinctions in patterns and input data, so that + characters that differ only in case match each other. Although + this is straightforward when letters differ in case only via + lowercase-uppercase pairs, the behavior is unspecified in other + situations. For example, uppercase “S” has an unusual lowercase + counterpart “ſ” (Unicode character U+017F, LATIN SMALL LETTER LONG + S) in many locales, and it is unspecified whether this unusual + character matches “S” or “s” even though uppercasing it yields “S”. + Another example: the lowercase German letter “ß” (U+00DF, LATIN + SMALL LETTER SHARP S) is normally capitalized as the two-character + string “SS” but it does not match “SS”, and it might not match the + uppercase letter “ẞ” (U+1E9E, LATIN CAPITAL LETTER SHARP S) even + though lowercasing the latter yields the former. + + ‘-y’ is an obsolete synonym that is provided for compatibility. + (‘-i’ is specified by POSIX.) + +‘--no-ignore-case’ + Do not ignore case distinctions in patterns and input data. This + is the default. This option is useful for passing to shell scripts + that already use ‘-i’, in order to cancel its effects because the + two options override each other. + +‘-v’ +‘--invert-match’ + Invert the sense of matching, to select non-matching lines. (‘-v’ + is specified by POSIX.) + +‘-w’ +‘--word-regexp’ + Select only those lines containing matches that form whole words. + The test is that the matching substring must either be at the + beginning of the line, or preceded by a non-word constituent + character. Similarly, it must be either at the end of the line or + followed by a non-word constituent character. Word constituent + characters are letters, digits, and the underscore. This option + has no effect if ‘-x’ is also specified. + + Because the ‘-w’ option can match a substring that does not begin + and end with word constituents, it differs from surrounding a + regular expression with ‘\<’ and ‘\>’. For example, although ‘grep + -w @’ matches a line containing only ‘@’, ‘grep '\<@\>'’ cannot + match any line because ‘@’ is not a word constituent. *Note The + Backslash Character and Special Expressions::. + +‘-x’ +‘--line-regexp’ + Select only those matches that exactly match the whole line. For + regular expression patterns, this is like parenthesizing each + pattern and then surrounding it with ‘^’ and ‘$’. (‘-x’ is + specified by POSIX.) + + +File: grep.info, Node: General Output Control, Next: Output Line Prefix Control, Prev: Matching Control, Up: Command-line Options + +2.1.3 General Output Control +---------------------------- + +‘-c’ +‘--count’ + Suppress normal output; instead print a count of matching lines for + each input file. With the ‘-v’ (‘--invert-match’) option, count + non-matching lines. (‘-c’ is specified by POSIX.) + +‘--color[=WHEN]’ +‘--colour[=WHEN]’ + Surround the matched (non-empty) strings, matching lines, context + lines, file names, line numbers, byte offsets, and separators (for + fields and groups of context lines) with escape sequences to + display them in color on the terminal. The colors are defined by + the environment variable ‘GREP_COLORS’ and default to + ‘ms=01;31:mc=01;31:sl=:cx=:fn=35:ln=32:bn=32:se=36’ for bold red + matched text, magenta file names, green line numbers, green byte + offsets, cyan separators, and default terminal colors otherwise. + The deprecated environment variable ‘GREP_COLOR’ is still + supported, but its setting does not have priority; it defaults to + ‘01;31’ (bold red) which only covers the color for matched text. + WHEN is ‘never’, ‘always’, or ‘auto’. + +‘-L’ +‘--files-without-match’ + Suppress normal output; instead print the name of each input file + from which no output would normally have been printed. + +‘-l’ +‘--files-with-matches’ + Suppress normal output; instead print the name of each input file + from which output would normally have been printed. Scanning each + input file stops upon first match. (‘-l’ is specified by POSIX.) + +‘-m NUM’ +‘--max-count=NUM’ + Stop after the first NUM selected lines. If the input is standard + input from a regular file, and NUM selected lines are output, + ‘grep’ ensures that the standard input is positioned just after the + last selected line before exiting, regardless of the presence of + trailing context lines. This enables a calling process to resume a + search. For example, the following shell script makes use of it: + + while grep -m 1 'PATTERN' + do + echo xxxx + done < FILE + + But the following probably will not work because a pipe is not a + regular file: + + # This probably will not work. + cat FILE | + while grep -m 1 'PATTERN' + do + echo xxxx + done + + When ‘grep’ stops after NUM selected lines, it outputs any trailing + context lines. When the ‘-c’ or ‘--count’ option is also used, + ‘grep’ does not output a count greater than NUM. When the ‘-v’ or + ‘--invert-match’ option is also used, ‘grep’ stops after outputting + NUM non-matching lines. + +‘-o’ +‘--only-matching’ + Print only the matched (non-empty) parts of matching lines, with + each such part on a separate output line. Output lines use the + same delimiters as input, and delimiters are null bytes if ‘-z’ + (‘--null-data’) is also used (*note Other Options::). + +‘-q’ +‘--quiet’ +‘--silent’ + Quiet; do not write anything to standard output. Exit immediately + with zero status if any match is found, even if an error was + detected. Also see the ‘-s’ or ‘--no-messages’ option. (‘-q’ is + specified by POSIX.) + +‘-s’ +‘--no-messages’ + Suppress error messages about nonexistent or unreadable files. + Portability note: unlike GNU ‘grep’, 7th Edition Unix ‘grep’ did + not conform to POSIX, because it lacked ‘-q’ and its ‘-s’ option + behaved like GNU ‘grep’’s ‘-q’ option.(1) USG-style ‘grep’ also + lacked ‘-q’ but its ‘-s’ option behaved like GNU ‘grep’’s. + Portable shell scripts should avoid both ‘-q’ and ‘-s’ and should + redirect standard and error output to ‘/dev/null’ instead. (‘-s’ + is specified by POSIX.) + + ---------- Footnotes ---------- + + (1) Of course, 7th Edition Unix predated POSIX by several years! + + +File: grep.info, Node: Output Line Prefix Control, Next: Context Line Control, Prev: General Output Control, Up: Command-line Options + +2.1.4 Output Line Prefix Control +-------------------------------- + +When several prefix fields are to be output, the order is always file +name, line number, and byte offset, regardless of the order in which +these options were specified. + +‘-b’ +‘--byte-offset’ + Print the 0-based byte offset within the input file before each + line of output. If ‘-o’ (‘--only-matching’) is specified, print + the offset of the matching part itself. + +‘-H’ +‘--with-filename’ + Print the file name for each match. This is the default when there + is more than one file to search. + +‘-h’ +‘--no-filename’ + Suppress the prefixing of file names on output. This is the + default when there is only one file (or only standard input) to + search. + +‘--label=LABEL’ + Display input actually coming from standard input as input coming + from file LABEL. This can be useful for commands that transform a + file’s contents before searching; e.g.: + + gzip -cd foo.gz | grep --label=foo -H 'some pattern' + +‘-n’ +‘--line-number’ + Prefix each line of output with the 1-based line number within its + input file. (‘-n’ is specified by POSIX.) + +‘-T’ +‘--initial-tab’ + Make sure that the first character of actual line content lies on a + tab stop, so that the alignment of tabs looks normal. This is + useful with options that prefix their output to the actual content: + ‘-H’, ‘-n’, and ‘-b’.

For example, ‘grep + -lZ’ outputs a zero byte after each file name instead of the usual + newline. This option makes the output unambiguous, even in the + presence of file names containing unusual characters like newlines. + This option can be used with commands like ‘find -print0’, ‘perl + -0’, ‘sort -z’, and ‘xargs -0’ to process arbitrary file names, + even those that contain newline characters. + + +File: grep.info, Node: Context Line Control, Next: File and Directory Selection, Prev: Output Line Prefix Control, Up: Command-line Options + +2.1.5 Context Line Control +-------------------------- + +“Context lines” are non-matching lines that are near a matching line. +They are output only if one of the following options are used. +Regardless of how these options are set, ‘grep’ never outputs any given +line more than once.

Non-text bytes + indicate binary data; these are either output bytes that are + improperly encoded for the current locale (*note Environment + Variables::), or null input bytes when the ‘-z’ (‘--null-data’) + option is not given (*note Other Options::). + + By default, TYPE is ‘binary’, and ‘grep’ suppresses output after + null input binary data is discovered, and suppresses output lines + that contain improperly encoded data. When some output is + suppressed, ‘grep’ follows any output with a one-line message + saying that a binary file matches. + + If TYPE is ‘without-match’, when ‘grep’ discovers null input binary + data it assumes that the rest of the file does not match; this is + equivalent to the ‘-I’ option. + + If TYPE is ‘text’, ‘grep’ processes binary data as if it were text; + this is equivalent to the ‘-a’ option. + + When TYPE is ‘binary’, ‘grep’ may treat non-text bytes as line + terminators even without the ‘-z’ (‘--null-data’) option. This + means choosing ‘binary’ versus ‘text’ can affect whether a pattern + matches a file. For example, when TYPE is ‘binary’ the pattern + ‘q$’ might match ‘q’ immediately followed by a null byte, even + though this is not matched when TYPE is ‘text’. Conversely, when + TYPE is ‘binary’ the pattern ‘.’ (period) might not match a null + byte. + + _Warning:_ The ‘-a’ (‘--binary-files=text’) option might output + binary garbage, which can have nasty side effects if the output is + a terminal and if the terminal driver interprets some of it as + commands. On the other hand, when reading files whose text + encodings are unknown, it can be helpful to use ‘-a’ or to set + ‘LC_ALL='C'’ in the environment, in order to find more matches even + if the matches are unsafe for direct display. + +‘-D ACTION’ +‘--devices=ACTION’ + If an input file is a device, FIFO, or socket, use ACTION to + process it. If ACTION is ‘read’, all devices are read just as if + they were ordinary files. If ACTION is ‘skip’, devices, FIFOs, and + sockets are silently skipped. By default, devices are read if they + are on the command line or if the ‘-R’ (‘--dereference-recursive’) + option is used, and are skipped if they are encountered recursively + and the ‘-r’ (‘--recursive’) option is used. This option has no + effect on a file that is read via standard input. + +‘-d ACTION’ +‘--directories=ACTION’ + If an input file is a directory, use ACTION to process it. By + default, ACTION is ‘read’, which means that directories are read + just as if they were ordinary files (some operating systems and + file systems disallow this, and will cause ‘grep’ to print error + messages for every directory or silently skip them). If ACTION is + ‘skip’, directories are silently skipped. If ACTION is ‘recurse’, + ‘grep’ reads all files under each directory, recursively, following + command-line symbolic links and skipping other symlinks; this is + equivalent to the ‘-r’ option. + +‘--exclude=GLOB’ + Skip any command-line file with a name suffix that matches the + pattern GLOB, using wildcard matching; a name suffix is either the + whole name, or a trailing part that starts with a non-slash + character immediately after a slash (‘/’) in the name. When + searching recursively, skip any subfile whose base name matches + GLOB; the base name is the part after the last slash. A pattern + can use ‘*’, ‘?’, and ‘[’...‘]’ as wildcards, and ‘\’ to quote a + wildcard or backslash character literally. + +‘--exclude-from=FILE’ + Skip files whose name matches any of the patterns read from FILE + (using wildcard matching as described under ‘--exclude’). + +‘--exclude-dir=GLOB’ + Skip any command-line directory with a name suffix that matches the + pattern GLOB. When searching recursively, skip any subdirectory + whose base name matches GLOB. Ignore any redundant trailing + slashes in GLOB. + +‘-I’ + Process a binary file as if it did not contain matching data; this + is equivalent to the ‘--binary-files=without-match’ option. + +‘--include=GLOB’ + Search only files whose name matches GLOB, using wildcard matching + as described under ‘--exclude’. If contradictory ‘--include’ and + ‘--exclude’ options are given, the last matching one wins. If no + ‘--include’ or ‘--exclude’ options match, a file is included unless + the first such option is ‘--include’. + +‘-r’ +‘--recursive’ + For each directory operand, read and process all files in that + directory, recursively. Follow symbolic links on the command line, + but skip symlinks that are encountered recursively. Note that if + no file operand is given, grep searches the working directory. + This is the same as the ‘--directories=recurse’ option. + +‘-R’ +‘--dereference-recursive’ + For each directory operand, read and process all files in that + directory, recursively, following all symbolic links. + + +File: grep.info, Node: Other Options, Prev: File and Directory Selection, Up: Command-line Options + +2.1.7 Other Options +------------------- + +‘--’ + Delimit the option list. Later arguments, if any, are treated as + operands even if they begin with ‘-’. For example, ‘grep PAT -- + -file1 file2’ searches for the pattern PAT in the files named + ‘-file1’ and ‘file2’. + +‘--line-buffered’ + Use line buffering for standard output, regardless of output + device. By default, standard output is line buffered for + interactive devices, and is fully buffered otherwise. With full + buffering, the output buffer is flushed when full; with line + buffering, the buffer is also flushed after every output line. The + buffer size is system dependent. + +‘-U’ +‘--binary’ + On platforms that distinguish between text and binary I/O, use the + latter when reading and writing files other than the user’s + terminal, so that all input bytes are read and written as-is. This + overrides the default behavior where ‘grep’ follows the operating + system’s advice whether to use text or binary I/O. On MS-Windows + when ‘grep’ uses text I/O it reads a carriage return–newline pair + as a newline and a Control-Z as end-of-file, and it writes a + newline as a carriage return–newline pair. + + When using text I/O ‘--byte-offset’ (‘-b’) counts and + ‘--binary-files’ heuristics apply to input data after text-I/O + processing. Also, the ‘--binary-files’ heuristics need not agree + with the ‘--binary’ option; that is, they may treat the data as + text even if ‘--binary’ is given, or vice versa. *Note File and + Directory Selection::. + + This option has no effect on GNU and other POSIX-compatible + platforms, which do not distinguish text from binary I/O. + +‘-z’ +‘--null-data’ + Treat input and output data as sequences of lines, each terminated + by a zero byte (the ASCII NUL character) instead of a newline. + Like the ‘-Z’ or ‘--null’ option, this option can be used with + commands like ‘sort -z’ to process arbitrary file names. + + +File: grep.info, Node: Environment Variables, Next: Exit Status, Prev: Command-line Options, Up: Invoking + +2.2 Environment Variables +========================= + +The behavior of ‘grep’ is affected by the following environment +variables. + + The locale for category ‘LC_FOO’ is specified by examining the three +environment variables ‘LC_ALL’, ‘LC_FOO’, and ‘LANG’, in that order. +The first of these variables that is set specifies the locale. For +example, if ‘LC_ALL’ is not set, but ‘LC_COLLATE’ is set to ‘pt_BR’, +then the Brazilian Portuguese locale is used for the ‘LC_COLLATE’ +category. As a special case for ‘LC_MESSAGES’ only, the environment +variable ‘LANGUAGE’ can contain a colon-separated list of languages that +overrides the three environment variables that ordinarily specify the +‘LC_MESSAGES’ category. The ‘C’ locale is used if none of these +environment variables are set, if the locale catalog is not installed, +or if ‘grep’ was not compiled with national language support (NLS). The +shell command ‘locale -a’ lists locales that are currently available. + + Many of the environment variables in the following list let you +control highlighting using Select Graphic Rendition (SGR) commands +interpreted by the terminal or terminal emulator. (See the section in +the documentation of your text terminal for permitted values and their +meanings as character attributes.) These substring values are integers +in decimal representation and can be concatenated with semicolons. +‘grep’ takes care of assembling the result into a complete SGR sequence +(‘\33[’...‘m’). Common values to concatenate include ‘1’ for bold, ‘4’ +for underline, ‘5’ for blink, ‘7’ for inverse, ‘39’ for default +foreground color, ‘30’ to ‘37’ for foreground colors, ‘90’ to ‘97’ for +16-color mode foreground colors, ‘38;5;0’ to ‘38;5;255’ for 88-color and +256-color modes foreground colors, ‘49’ for default background color, +‘40’ to ‘47’ for background colors, ‘100’ to ‘107’ for 16-color mode +background colors, and ‘48;5;0’ to ‘48;5;255’ for 88-color and 256-color +modes background colors. + + The two-letter names used in the ‘GREP_COLORS’ environment variable +(and some of the others) refer to terminal “capabilities,” the ability +of a terminal to highlight text, or change its color, and so on. These +capabilities are stored in an online database and accessed by the +‘terminfo’ library. + +‘GREP_COLOR’ + This variable specifies the color used to highlight matched + (non-empty) text. It is deprecated in favor of ‘GREP_COLORS’, but + still supported. The ‘mt’, ‘ms’, and ‘mc’ capabilities of + ‘GREP_COLORS’ have priority over it. It can only specify the color + used to highlight the matching non-empty text in any matching line + (a selected line when the ‘-v’ command-line option is omitted, or a + context line when ‘-v’ is specified). The default is ‘01;31’, + which means a bold red foreground text on the terminal’s default + background. + +‘GREP_COLORS’ + This variable specifies the colors and other attributes used to + highlight various parts of the output. Its value is a + colon-separated list of ‘terminfo’ capabilities that defaults to + ‘ms=01;31:mc=01;31:sl=:cx=:fn=35:ln=32:bn=32:se=36’ with the ‘rv’ + and ‘ne’ boolean capabilities omitted (i.e., false). Supported + capabilities are as follows. + + ‘sl=’ + SGR substring for whole selected lines (i.e., matching lines + when the ‘-v’ command-line option is omitted, or non-matching + lines when ‘-v’ is specified). If however the boolean ‘rv’ + capability and the ‘-v’ command-line option are both + specified, it applies to context matching lines instead. The + default is empty (i.e., the terminal’s default color pair). + + ‘cx=’ + SGR substring for whole context lines (i.e., non-matching + lines when the ‘-v’ command-line option is omitted, or + matching lines when ‘-v’ is specified). If however the + boolean ‘rv’ capability and the ‘-v’ command-line option are + both specified, it applies to selected non-matching lines + instead. The default is empty (i.e., the terminal’s default + color pair). + + ‘rv’ + Boolean value that reverses (swaps) the meanings of the ‘sl=’ + and ‘cx=’ capabilities when the ‘-v’ command-line option is + specified. The default is false (i.e., the capability is + omitted). + + ‘mt=01;31’ + SGR substring for matching non-empty text in any matching line + (i.e., a selected line when the ‘-v’ command-line option is + omitted, or a context line when ‘-v’ is specified). Setting + this is equivalent to setting both ‘ms=’ and ‘mc=’ at once to + the same value. The default is a bold red text foreground + over the current line background. + + ‘ms=01;31’ + SGR substring for matching non-empty text in a selected line. + (This is used only when the ‘-v’ command-line option is + omitted.) The effect of the ‘sl=’ (or ‘cx=’ if ‘rv’) + capability remains active when this takes effect. The default + is a bold red text foreground over the current line + background. + + ‘mc=01;31’ + SGR substring for matching non-empty text in a context line. + (This is used only when the ‘-v’ command-line option is + specified.) The effect of the ‘cx=’ (or ‘sl=’ if ‘rv’) + capability remains active when this takes effect. The default + is a bold red text foreground over the current line + background. + + ‘fn=35’ + SGR substring for file names prefixing any content line. The + default is a magenta text foreground over the terminal’s + default background. + + ‘ln=32’ + SGR substring for line numbers prefixing any content line. + The default is a green text foreground over the terminal’s + default background. + + ‘bn=32’ + SGR substring for byte offsets prefixing any content line. + The default is a green text foreground over the terminal’s + default background. + + ‘se=36’ + SGR substring for separators that are inserted between + selected line fields (‘:’), between context line fields (‘-’), + and between groups of adjacent lines when nonzero context is + specified (‘--’). The default is a cyan text foreground over + the terminal’s default background. + + ‘ne’ + Boolean value that prevents clearing to the end of line using + Erase in Line (EL) to Right (‘\33[K’) each time a colorized + item ends. This is needed on terminals on which EL is not + supported. It is otherwise useful on terminals for which the + ‘back_color_erase’ (‘bce’) boolean ‘terminfo’ capability does + not apply, when the chosen highlight colors do not affect the + background, or when EL is too slow or causes too much flicker. + The default is false (i.e., the capability is omitted). + + Note that boolean capabilities have no ‘=’... part. They are + omitted (i.e., false) by default and become true when specified. + +‘LC_ALL’ +‘LC_COLLATE’ +‘LANG’ + These variables specify the locale for the ‘LC_COLLATE’ category, + which might affect how range expressions like ‘[a-z]’ are + interpreted. + +‘LC_ALL’ +‘LC_CTYPE’ +‘LANG’ + These variables specify the locale for the ‘LC_CTYPE’ category, + which determines the type of characters, e.g., which characters are + whitespace. This category also determines the character encoding. + *Note Character Encoding::. + +‘LANGUAGE’ +‘LC_ALL’ +‘LC_MESSAGES’ +‘LANG’ + These variables specify the locale for the ‘LC_MESSAGES’ category, + which determines the language that ‘grep’ uses for messages. The + default ‘C’ locale uses American English messages. + +‘POSIXLY_CORRECT’ + If set, ‘grep’ behaves as POSIX requires; otherwise, ‘grep’ behaves + more like other GNU programs. POSIX requires that options that + follow file names must be treated as file names; by default, such + options are permuted to the front of the operand list and are + treated as options. Also, ‘POSIXLY_CORRECT’ disables special + handling of an invalid bracket expression. *Note + invalid-bracket-expr::. + +‘_N_GNU_nonoption_argv_flags_’ + (Here ‘N’ is ‘grep’’s numeric process ID.) If the Ith character of + this environment variable’s value is ‘1’, do not consider the Ith + operand of ‘grep’ to be an option, even if it appears to be one. A + shell can put this variable in the environment for each command it + runs, specifying which operands are the results of file name + wildcard expansion and therefore should not be treated as options. + This behavior is available only with the GNU C library, and only + when ‘POSIXLY_CORRECT’ is not set. + + The ‘GREP_OPTIONS’ environment variable of ‘grep’ 2.20 and earlier is +no longer supported, as it caused problems when writing portable +scripts. To make arbitrary changes to how ‘grep’ works, you can use an +alias or script instead. For example, if ‘grep’ is in the directory +‘/usr/bin’ you can prepend ‘$HOME/bin’ to your ‘PATH’ and create an +executable script ‘$HOME/bin/grep’ containing the following: + + #! /bin/sh + export PATH=/usr/bin + exec grep --color=auto --devices=skip "$@" + + +File: grep.info, Node: Exit Status, Next: grep Programs, Prev: Environment Variables, Up: Invoking + +2.3 Exit Status +=============== + +Normally the exit status is 0 if a line is selected, 1 if no lines were +selected, and 2 if an error occurred.

In GNU +‘grep’, there is no difference in available functionality between the +basic and extended syntaxes. In other implementations, basic regular +expressions are less powerful. The following description applies to +extended regular expressions; differences for basic regular expressions +are summarized afterwards. Perl-compatible regular expressions give +additional functionality, and are documented in the pcresyntax(3) and +pcrepattern(3) manual pages, but work only if PCRE is available in the +system. + +* Menu: + +* Fundamental Structure:: +* Character Classes and Bracket Expressions:: +* The Backslash Character and Special Expressions:: +* Anchoring:: +* Back-references and Subexpressions:: +* Basic vs Extended:: +* Character Encoding:: +* Matching Non-ASCII:: + + +File: grep.info, Node: Fundamental Structure, Next: Character Classes and Bracket Expressions, Up: Regular Expressions + +3.1 Fundamental Structure +========================= + +In regular expressions, the characters ‘.?*+{|()[\^$’ are “special +characters” and have uses described below. All other characters are +“ordinary characters”, and each ordinary character is a regular +expression that matches itself. + + The period ‘.’ matches any single character. It is unspecified +whether ‘.’ matches an encoding error. + + A regular expression may be followed by one of several repetition +operators; the operators beginning with ‘{’ are called “interval +expressions”. + +‘?’ + The preceding item is optional and is matched at most once. + +‘*’ + The preceding item is matched zero or more times. + +‘+’ + The preceding item is matched one or more times. + +‘{N}’ + The preceding item is matched exactly N times. + +‘{N,}’ + The preceding item is matched N or more times. + +‘{,M}’ + The preceding item is matched at most M times. This is a GNU + extension. + +‘{N,M}’ + The preceding item is matched at least N times, but not more than M + times. + + The empty regular expression matches the empty string. Two regular +expressions may be concatenated; the resulting regular expression +matches any string formed by concatenating two substrings that +respectively match the concatenated expressions. + + Two regular expressions may be joined by the infix operator ‘|’; the +resulting regular expression matches any string matching either +alternate expression. + + Repetition takes precedence over concatenation, which in turn takes +precedence over alternation. A whole expression may be enclosed in +parentheses to override these precedence rules and form a subexpression. +An unmatched ‘)’ matches just itself. + + +File: grep.info, Node: Character Classes and Bracket Expressions, Next: The Backslash Character and Special Expressions, Prev: Fundamental Structure, Up: Regular Expressions + +3.2 Character Classes and Bracket Expressions +============================================= + +A “bracket expression” is a list of characters enclosed by ‘[’ and ‘]’. +It matches any single character in that list. If the first character of +the list is the caret ‘^’, then it matches any character *not* in the +list, and it is unspecified whether it matches an encoding error. For +example, the regular expression ‘[0123456789]’ matches any single digit, +whereas ‘[^()]’ matches any single character that is not an opening or +closing parenthesis, and might or might not match an encoding error. + + Within a bracket expression, a “range expression” consists of two +characters separated by a hyphen. It matches any single character that +sorts between the two characters, inclusive. In the default C locale, +the sorting sequence is the native character order; for example, ‘[a-d]’ +is equivalent to ‘[abcd]’. In other locales, the sorting sequence is +not specified, and ‘[a-d]’ might be equivalent to ‘[abcd]’ or to +‘[aBbCcDd]’, or it might fail to match any character, or the set of +characters that it matches might even be erratic. To obtain the +traditional interpretation of bracket expressions, you can use the ‘C’ +locale by setting the ‘LC_ALL’ environment variable to the value ‘C’. + + Finally, certain named classes of characters are predefined within +bracket expressions, as follows. Their interpretation depends on the +‘LC_CTYPE’ locale; for example, ‘[[:alnum:]]’ means the character class +of numbers and letters in the current locale. + +‘[:alnum:]’ + Alphanumeric characters: ‘[:alpha:]’ and ‘[:digit:]’; in the ‘C’ + locale and ASCII character encoding, this is the same as + ‘[0-9A-Za-z]’. + +‘[:alpha:]’ + Alphabetic characters: ‘[:lower:]’ and ‘[:upper:]’; in the ‘C’ + locale and ASCII character encoding, this is the same as + ‘[A-Za-z]’. + +‘[:blank:]’ + Blank characters: space and tab. + +‘[:cntrl:]’ + Control characters. In ASCII, these characters have octal codes + 000 through 037, and 177 (DEL). In other character sets, these are + the equivalent characters, if any. + +‘[:digit:]’ + Digits: ‘0 1 2 3 4 5 6 7 8 9’. + +‘[:graph:]’ + Graphical characters: ‘[:alnum:]’ and ‘[:punct:]’. + +‘[:lower:]’ + Lower-case letters; in the ‘C’ locale and ASCII character encoding, + this is ‘a b c d e f g h i j k l m n o p q r s t u v w x y z’. + +‘[:print:]’ + Printable characters: ‘[:alnum:]’, ‘[:punct:]’, and space. + +‘[:punct:]’ + Punctuation characters; in the ‘C’ locale and ASCII character + encoding, this is ‘! " # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \ + ] ^ _ ` { | } ~’. + +‘[:space:]’ + Space characters: in the ‘C’ locale, this is tab, newline, vertical + tab, form feed, carriage return, and space. *Note Usage::, for + more discussion of matching newlines. + +‘[:upper:]’ + Upper-case letters: in the ‘C’ locale and ASCII character encoding, + this is ‘A B C D E F G H I J K L M N O P Q R S T U V W X Y Z’. + +‘[:xdigit:]’ + Hexadecimal digits: ‘0 1 2 3 4 5 6 7 8 9 A B C D E F a b c d e f’. + + Note that the brackets in these class names are part of the symbolic +names, and must be included in addition to the brackets delimiting the +bracket expression. + + If you mistakenly omit the outer brackets, and search for say, +‘[:upper:]’, GNU ‘grep’ prints a diagnostic and exits with status 2, on +the assumption that you did not intend to search for the nominally +equivalent regular expression: ‘[:epru]’. Set the ‘POSIXLY_CORRECT’ +environment variable to disable this feature. + + Special characters lose their special meaning inside bracket +expressions. + +‘]’ + ends the bracket expression if it’s not the first list item. So, + if you want to make the ‘]’ character a list item, you must put it + first. + +‘[.’ + represents the open collating symbol. + +‘.]’ + represents the close collating symbol. + +‘[=’ + represents the open equivalence class. + +‘=]’ + represents the close equivalence class. + +‘[:’ + represents the open character class symbol, and should be followed + by a valid character class name. + +‘:]’ + represents the close character class symbol. + +‘-’ + represents the range if it’s not first or last in a list or the + ending point of a range. + +‘^’ + represents the characters not in the list.

Also, a backslash is needed +before an interval expression’s closing ‘}’, and an unmatched ‘\)’ is +invalid. + + Portable scripts should avoid the following constructs, as POSIX says +they produce undefined results: + + • Extended regular expressions that use back-references. + • Basic regular expressions that use ‘\?’, ‘\+’, or ‘\|’. + • Empty parenthesized regular expressions like ‘()’. + • Empty alternatives (as in, e.g, ‘a|’). + • Repetition operators that immediately follow empty expressions, + unescaped ‘$’, or other repetition operators. + • A backslash escaping an ordinary character (e.g., ‘\S’), unless it + is a back-reference. + • An unescaped ‘[’ that is not part of a bracket expression. + • In extended regular expressions, an unescaped ‘{’ that is not part + of an interval expression. + + Traditional ‘egrep’ did not support interval expressions and some +‘egrep’ implementations use ‘\{’ and ‘\}’ instead, so portable scripts +should avoid interval expressions in ‘grep -E’ patterns and should use +‘[{]’ to match a literal ‘{’. + + GNU ‘grep -E’ attempts to support traditional usage by assuming that +‘{’ is not special if it would be the start of an invalid interval +expression. For example, the command ‘grep -E '{1'’ searches for the +two-character string ‘{1’ instead of reporting a syntax error in the +regular expression. POSIX allows this behavior as an extension, but +portable scripts should avoid it. + + +File: grep.info, Node: Character Encoding, Next: Matching Non-ASCII, Prev: Basic vs Extended, Up: Regular Expressions + +3.7 Character Encoding +====================== + +The ‘LC_CTYPE’ locale specifies the encoding of characters in patterns +and data, that is, whether text is encoded in UTF-8, ASCII, or some +other encoding. *Note Environment Variables::. + + In the ‘C’ or ‘POSIX’ locale, every character is encoded as a single +byte and every byte is a valid character. In more-complex encodings +such as UTF-8, a sequence of multiple bytes may be needed to represent a +character, and some bytes may be encoding errors that do not contribute +to the representation of any character. POSIX does not specify the +behavior of ‘grep’ when patterns or input data contain encoding errors +or null characters, so portable scripts should avoid such usage. As an +extension to POSIX, GNU ‘grep’ treats null characters like any other +character. However, unless the ‘-a’ (‘--binary-files=text’) option is +used, the presence of null characters in input or of encoding errors in +output causes GNU ‘grep’ to treat the file as binary and suppress +details about matches. *Note File and Directory Selection::. + + Regardless of locale, the 103 characters in the POSIX Portable +Character Set (a subset of ASCII) are always encoded as a single byte, +and the 128 ASCII characters have their usual single-byte encodings on +all but oddball platforms. + + +File: grep.info, Node: Matching Non-ASCII, Prev: Character Encoding, Up: Regular Expressions + +3.8 Matching Non-ASCII and Non-printable Characters +=================================================== + +In a regular expression, non-ASCII and non-printable characters other +than newline are not special, and represent themselves. For example, in +a locale using UTF-8 the command ‘grep 'Λ ω'’ (where the white space +between ‘Λ’ and the ‘ω’ is a tab character) searches for ‘Λ’ (Unicode +character U+039B GREEK CAPITAL LETTER LAMBDA), followed by a tab (U+0009 +TAB), followed by ‘ω’ (U+03C9 GREEK SMALL LETTER OMEGA). + + Suppose you want to limit your pattern to only printable characters +(or even only printable ASCII characters) to keep your script readable +or portable, but you also want to match specific non-ASCII or non-null +non-printable characters. If you are using the ‘-P’ (‘--perl-regexp’) +option, PCREs give you several ways to do this. Otherwise, if you are +using Bash, the GNU project’s shell, you can represent these characters +via ANSI-C quoting. For example, the Bash commands ‘grep $'Λ\tω'’ and +‘grep $'\u039B\t\u03C9'’ both search for the same three-character string +‘Λ ω’ mentioned earlier. However, because Bash translates ANSI-C +quoting before ‘grep’ sees the pattern, this technique should not be +used to match printable ASCII characters; for example, ‘grep $'\u005E'’ +is equivalent to ‘grep '^'’ and matches any line, not just lines +containing the character ‘^’ (U+005E CIRCUMFLEX ACCENT). + + Since PCREs and ANSI-C quoting are GNU extensions to POSIX, portable +shell scripts written in ASCII should use other methods to match +specific non-ASCII characters. For example, in a UTF-8 locale the +command ‘grep "$(printf '\316\233\t\317\211\n')"’ is a portable albeit +hard-to-read alternative to Bash’s ‘grep $'Λ\tω'’. However, none of +these techniques will let you put a null character directly into a +command-line pattern; null characters can appear only in a pattern +specified via the ‘-f’ (‘--file’) option. + + +File: grep.info, Node: Usage, Next: Performance, Prev: Regular Expressions, Up: Top + +4 Usage +******* + +Here is an example command that invokes GNU ‘grep’: + + grep -i 'hello.*world' menu.h main.c + +This lists all lines in the files ‘menu.h’ and ‘main.c’ that contain the +string ‘hello’ followed by the string ‘world’; this is because ‘.*’ +matches zero or more characters within a line. *Note Regular +Expressions::. The ‘-i’ option causes ‘grep’ to ignore case, causing it +to match the line ‘Hello, world!’, which it would not otherwise match. + + Here is a more complex example, showing the location and contents of +any line containing ‘f’ and ending in ‘.c’, within all files in the +current directory whose names start with non-‘.’, contain ‘g’, and end +in ‘.h’. The ‘-n’ option outputs line numbers, the ‘--’ argument treats +any later arguments as file names not options even if ‘*g*.h’ expands to +a file name that starts with ‘-’, and the empty file ‘/dev/null’ causes +file names to be output even if only one file name happens to be of the +form ‘*g*.h’. + + grep -n -- 'f.*\.c$' *g*.h /dev/null + +Note that the regular expression syntax used in the pattern differs from +the globbing syntax that the shell uses to match file names. + + *Note Invoking::, for more details about how to invoke ‘grep’. + + Here are some common questions and answers about ‘grep’ usage. + + 1. How can I list just the names of matching files? + + grep -l 'main' test-*.c + + lists names of ‘test-*.c’ files in the current directory whose + contents mention ‘main’. + + 2. How do I search directories recursively? + + grep -r 'hello' /home/gigi + + searches for ‘hello’ in all files under the ‘/home/gigi’ directory. + For more control over which files are searched, use ‘find’ and + ‘grep’. For example, the following command searches only C files: + + find /home/gigi -name '*.c' ! -type d \ + -exec grep -H 'hello' '{}' + + + This differs from the command: + + grep -H 'hello' /home/gigi/*.c + + which merely looks for ‘hello’ in non-hidden C files in + ‘/home/gigi’ whose names end in ‘.c’. The ‘find’ command line + above is more similar to the command: + + grep -r --include='*.c' 'hello' /home/gigi + + 3. What if a pattern or file has a leading ‘-’? + + grep -- '--cut here--' * + + searches for all lines matching ‘--cut here--’. Without ‘--’, + ‘grep’ would attempt to parse ‘--cut here--’ as a list of options, + and there would be similar problems with any file names beginning + with ‘-’. + + Alternatively, you can prevent misinterpretation of leading ‘-’ by + using ‘-e’ for patterns and leading ‘./’ for files: + + grep -e '--cut here--' ./* + + 4. Suppose I want to search for a whole word, not a part of a word? + + grep -w 'hello' test*.log + + searches only for instances of ‘hello’ that are entire words; it + does not match ‘Othello’. For more control, use ‘\<’ and ‘\>’ to + match the start and end of words. For example: + + grep 'hello\>' test*.log + + searches only for words ending in ‘hello’, so it matches the word + ‘Othello’. + + 5. How do I output context around the matching lines? + + grep -C 2 'hello' test*.log + + prints two lines of context around each matching line. + + 6. How do I force ‘grep’ to print the name of the file? + + Append ‘/dev/null’: + + grep 'eli' /etc/passwd /dev/null + + gets you: + + /etc/passwd:eli:x:2098:1000:Eli Smith:/home/eli:/bin/bash + + Alternatively, use ‘-H’, which is a GNU extension: + + grep -H 'eli' /etc/passwd + + 7. Why do people use strange regular expressions on ‘ps’ output? + + ps -ef | grep '[c]ron' + + If the pattern had been written without the square brackets, it + would have matched not only the ‘ps’ output line for ‘cron’, but + also the ‘ps’ output line for ‘grep’. Note that on some platforms, + ‘ps’ limits the output to the width of the screen; ‘grep’ does not + have any limit on the length of a line except the available memory. + + 8. Why does ‘grep’ report “Binary file matches”? + + If ‘grep’ listed all matching “lines” from a binary file, it would + probably generate output that is not useful, and it might even muck + up your display. So GNU ‘grep’ suppresses output from files that + appear to be binary files. To force GNU ‘grep’ to output lines + even from files that appear to be binary, use the ‘-a’ or + ‘--binary-files=text’ option. To eliminate the “Binary file + matches” messages, use the ‘-I’ or ‘--binary-files=without-match’ + option, or the ‘-s’ or ‘--no-messages’ option. + + 9. Why doesn’t ‘grep -lv’ print non-matching file names? + + ‘grep -lv’ lists the names of all files containing one or more + lines that do not match. To list the names of all files that + contain no matching lines, use the ‘-L’ or ‘--files-without-match’ + option. + + 10. I can do “OR” with ‘|’, but what about “AND”? + + grep 'paul' /etc/motd | grep 'franc,ois' + + finds all lines that contain both ‘paul’ and ‘franc,ois’. + + 11. Why does the empty pattern match every input line? + + The ‘grep’ command searches for lines that contain strings that + match a pattern. Every line contains the empty string, so an empty + pattern causes ‘grep’ to find a match on each line. It is not the + only such pattern: ‘^’, ‘$’, and many other patterns cause ‘grep’ + to match every line. + + To match empty lines, use the pattern ‘^$’. To match blank lines, + use the pattern ‘^[[:blank:]]*$’. To match no lines at all, use + the command ‘grep -f /dev/null’. + + 12. How can I search in both standard input and in files? + + Use the special file name ‘-’: + + cat /etc/passwd | grep 'alain' - /etc/motd + + 13. Why is this back-reference failing? + + echo 'ba' | grep -E '(a)\1|b\1' + + This outputs an error message, because the second ‘\1’ has nothing + to refer back to, meaning it will never match anything. + + 14. How can I match across lines? + + Standard grep cannot do this, as it is fundamentally line-based. + Therefore, merely using the ‘[:space:]’ character class does not + match newlines in the way you might expect. + + With the GNU ‘grep’ option ‘-z’ (‘--null-data’), each input and + output “line” is null-terminated; *note Other Options::. Thus, you + can match newlines in the input, but typically if there is a match + the entire input is output, so this usage is often combined with + output-suppressing options like ‘-q’, e.g.: + + printf 'foo\nbar\n' | grep -z -q 'foo[[:space:]]\+bar' + + If this does not suffice, you can transform the input before giving + it to ‘grep’, or turn to ‘awk’, ‘sed’, ‘perl’, or many other + utilities that are designed to operate across lines. + + 15. What do ‘grep’, ‘fgrep’, and ‘egrep’ stand for? + + The name ‘grep’ comes from the way line editing was done on Unix. + For example, ‘ed’ uses the following syntax to print a list of + matching lines on the screen: + + global/regular expression/print + g/re/p + + ‘fgrep’ stands for Fixed ‘grep’; ‘egrep’ stands for Extended + ‘grep’. + + +File: grep.info, Node: Performance, Next: Reporting Bugs, Prev: Usage, Up: Top + +5 Performance +************* + +Typically ‘grep’ is an efficient way to search text. However, it can be +quite slow in some cases, and it can search large files where even minor +performance tweaking can help significantly. Although the algorithm +used by ‘grep’ is an implementation detail that can change from release +to release, understanding its basic strengths and weaknesses can help +you improve its performance. + + The ‘grep’ command operates partly via a set of automata that are +designed for efficiency, and partly via a slower matcher that takes over +when the fast matchers run into unusual features like back-references. +When feasible, the Boyer–Moore fast string searching algorithm is used +to match a single fixed pattern, and the Aho–Corasick algorithm is used +to match multiple fixed patterns. + + Generally speaking ‘grep’ operates more efficiently in single-byte +locales, since it can avoid the special processing needed for multi-byte +characters. If your patterns will work just as well that way, setting +‘LC_ALL’ to a single-byte locale can help performance considerably. +Setting ‘LC_ALL='C'’ can be particularly efficient, as ‘grep’ is tuned +for that locale. + + Outside the ‘C’ locale, case-insensitive search, and search for +bracket expressions like ‘[a-z]’ and ‘[[=a=]b]’, can be surprisingly +inefficient due to difficulties in fast portable access to concepts like +multi-character collating elements. + + A back-reference such as ‘\1’ can hurt performance significantly in +some cases, since back-references cannot in general be implemented via a +finite state automaton, and instead trigger a backtracking algorithm +that can be quite inefficient. For example, although the pattern +‘^(.*)\1{14}(.*)\2{13}$’ matches only lines whose lengths can be written +as a sum 15x + 14y for nonnegative integers x and y, the pattern matcher +does not perform linear Diophantine analysis and instead backtracks +through all possible matching strings, using an algorithm that is +exponential in the worst case. + + On some operating systems that support files with holes—large regions +of zeros that are not physically present on secondary storage—‘grep’ can +skip over the holes efficiently without needing to read the zeros. This +optimization is not available if the ‘-a’ (‘--binary-files=text’) option +is used (*note File and Directory Selection::), unless the ‘-z’ +(‘--null-data’) option is also used (*note Other Options::). + + For more about the algorithms used by ‘grep’ and about related string +matching algorithms, see: + + • Aho AV.

In addition, certain other obscure regular expressions +require exponential time and space, and may cause ‘grep’ to run out of +memory. + + Back-references can greatly slow down matching, as they can generate +exponentially many matching possibilities that can consume both time and +memory to explore. Also, the POSIX specification for back-references is +at times unclear. Furthermore, many regular expression implementations +have back-reference bugs that can cause programs to return incorrect +answers or even crash, and fixing these bugs has often been +low-priority: for example, as of 2021 the GNU C library bug database +(https://sourceware.org/bugzilla/) contained back-reference bugs 52, +10844, 11053, 24269 and 25322, with little sign of forthcoming fixes. +Luckily, back-references are rarely useful and it should be little +trouble to avoid them in practical applications. + + +File: grep.info, Node: Copying, Next: Index, Prev: Reporting Bugs, Up: Top + +7 Copying +********* + +GNU ‘grep’ is licensed under the GNU GPL, which makes it “free +software”. + + The “free” in “free software” refers to liberty, not price.

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 + <https://www.gnu.org/licenses/>. + + 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: grep.info, Node: Index, Prev: Copying, Up: Top + +Index +***** + +�[index�] +* Menu: + +* *: Fundamental Structure. + (line 22) +* +: Fundamental Structure. + (line 25) +* --: Other Options.

For example, uppercase ``S'' has an +unusual lowercase counterpart ``ſ'' (Unicode character U+017F, LATIN +SMALL LETTER LONG S) in many locales, and it is unspecified whether +this unusual character matches ``S'' or ``s'' even though uppercasing +it yields ``S''. Another example: the lowercase German letter ``ß'' +(U+00DF, LATIN SMALL LETTER SHARP S) is normally capitalized as the +two-character string ``SS'' but it does not match ``SS'', and it might +not match the uppercase letter ``ẞ'' (U+1E9E, LATIN CAPITAL LETTER +SHARP S) even though lowercasing the latter yields the former. + +@option{-y} is an obsolete synonym that is provided for compatibility. +(@option{-i} is specified by POSIX.) + +@item --no-ignore-case +@opindex --no-ignore-case +Do not ignore case distinctions in patterns and input data.

In more-complex +encodings such as UTF-8, a sequence of multiple bytes may be needed to +represent a character, and some bytes may be encoding errors that do +not contribute to the representation of any character. POSIX does not +specify the behavior of @command{grep} when patterns or input data +contain encoding errors or null characters, so portable scripts should +avoid such usage. As an extension to POSIX, GNU @command{grep} treats +null characters like any other character. However, unless the +@option{-a} (@option{--binary-files=text}) option is used, the +presence of null characters in input or of encoding errors in output +causes GNU @command{grep} to treat the file as binary and suppress +details about matches. @xref{File and Directory Selection}. + +Regardless of locale, the 103 characters in the POSIX Portable +Character Set (a subset of ASCII) are always encoded as a single byte, +and the 128 ASCII characters have their usual single-byte encodings on +all but oddball platforms. + +@node Matching Non-ASCII +@section Matching Non-ASCII and Non-printable Characters +@cindex non-ASCII matching +@cindex non-printable matching + +In a regular expression, non-ASCII and non-printable characters other +than newline are not special, and represent themselves. For example, +in a locale using UTF-8 the command @samp{grep 'Λ@tie{}ω'} (where the +white space between @samp{Λ} and the @samp{ω} is a tab character) +searches for @samp{Λ} (Unicode character U+039B GREEK CAPITAL LETTER +LAMBDA), followed by a tab (U+0009 TAB), followed by @samp{ω} (U+03C9 +GREEK SMALL LETTER OMEGA). + +Suppose you want to limit your pattern to only printable characters +(or even only printable ASCII characters) to keep your script readable +or portable, but you also want to match specific non-ASCII or non-null +non-printable characters. If you are using the @option{-P} +(@option{--perl-regexp}) option, PCREs give you several ways to do +this. Otherwise, if you are using Bash, the GNU project's shell, you +can represent these characters via ANSI-C quoting. For example, the +Bash commands @samp{grep $'Λ\tω'} and @samp{grep $'\u039B\t\u03C9'} +both search for the same three-character string @samp{Λ@tie{}ω} +mentioned earlier. However, because Bash translates ANSI-C quoting +before @command{grep} sees the pattern, this technique should not be +used to match printable ASCII characters; for example, @samp{grep +$'\u005E'} is equivalent to @samp{grep '^'} and matches any line, not +just lines containing the character @samp{^} (U+005E CIRCUMFLEX +ACCENT). + +Since PCREs and ANSI-C quoting are GNU extensions to POSIX, portable +shell scripts written in ASCII should use other methods to match +specific non-ASCII characters. For example, in a UTF-8 locale the +command @samp{grep "$(printf '\316\233\t\317\211\n')"} is a portable +albeit hard-to-read alternative to Bash's @samp{grep $'Λ\tω'}. +However, none of these techniques will let you put a null character +directly into a command-line pattern; null characters can appear only +in a pattern specified via the @option{-f} (@option{--file}) option. + +@node Usage +@chapter Usage + +@cindex usage, examples +Here is an example command that invokes GNU @command{grep}: + +@example +grep -i 'hello.*world' menu.h main.c +@end example + +@noindent +This lists all lines in the files @file{menu.h} and @file{main.c} that +contain the string @samp{hello} followed by the string @samp{world}; +this is because @samp{.*} matches zero or more characters within a line. +@xref{Regular Expressions}. +The @option{-i} option causes @command{grep} +to ignore case, causing it to match the line @samp{Hello, world!}, which +it would not otherwise match. + +Here is a more complex example, +showing the location and contents of any line +containing @samp{f} and ending in @samp{.c}, +within all files in the current directory whose names +start with non-@samp{.}, contain @samp{g}, and end in @samp{.h}. +The @option{-n} option outputs line numbers, the @option{--} argument +treats any later arguments as file names not options even if +@code{*g*.h} expands to a file name that starts with @samp{-}, +and the empty file @file{/dev/null} causes file names to be output +even if only one file name happens to be of the form @samp{*g*.h}. + +@example +grep -n -- 'f.*\.c$' *g*.h /dev/null +@end example + +@noindent +Note that the regular expression syntax used in the pattern differs +from the globbing syntax that the shell uses to match file names. + +@xref{Invoking}, for more details about +how to invoke @command{grep}. + +@cindex using @command{grep}, Q&A +@cindex FAQ about @command{grep} usage +Here are some common questions and answers about @command{grep} usage. + +@enumerate + +@item +How can I list just the names of matching files? + +@example +grep -l 'main' test-*.c +@end example + +@noindent +lists names of @samp{test-*.c} files in the current directory whose contents +mention @samp{main}. + +@item +How do I search directories recursively? + +@example +grep -r 'hello' /home/gigi +@end example + +@noindent +searches for @samp{hello} in all files +under the @file{/home/gigi} directory. +For more control over which files are searched, +use @command{find} and @command{grep}. +For example, the following command searches only C files: + +@example +find /home/gigi -name '*.c' ! -type d \ + -exec grep -H 'hello' '@{@}' + +@end example + +This differs from the command: + +@example +grep -H 'hello' /home/gigi/*.c +@end example + +which merely looks for @samp{hello} in non-hidden C files in +@file{/home/gigi} whose names end in @samp{.c}. +The @command{find} command line above is more similar to the command: + +@example +grep -r --include='*.c' 'hello' /home/gigi +@end example + +@item +What if a pattern or file has a leading @samp{-}? + +@example +grep -- '--cut here--' * +@end example + +@noindent +searches for all lines matching @samp{--cut here--}. +Without @option{--}, +@command{grep} would attempt to parse @samp{--cut here--} as a list of +options, and there would be similar problems with any file names +beginning with @samp{-}. + +Alternatively, you can prevent misinterpretation of leading @samp{-} +by using @option{-e} for patterns and leading @samp{./} for files: + +@example +grep -e '--cut here--' ./* +@end example + +@item +Suppose I want to search for a whole word, not a part of a word? + +@example +grep -w 'hello' test*.log +@end example + +@noindent +searches only for instances of @samp{hello} that are entire words; +it does not match @samp{Othello}. +For more control, use @samp{\<} and +@samp{\>} to match the start and end of words. +For example: + +@example +grep 'hello\>' test*.log +@end example + +@noindent +searches only for words ending in @samp{hello}, so it matches the word +@samp{Othello}. + +@item +How do I output context around the matching lines? + +@example +grep -C 2 'hello' test*.log +@end example + +@noindent +prints two lines of context around each matching line. + +@item +How do I force @command{grep} to print the name of the file? + +Append @file{/dev/null}: + +@example +grep 'eli' /etc/passwd /dev/null +@end example + +gets you: + +@example +/etc/passwd:eli:x:2098:1000:Eli Smith:/home/eli:/bin/bash +@end example + +Alternatively, use @option{-H}, which is a GNU extension: + +@example +grep -H 'eli' /etc/passwd +@end example + +@item +Why do people use strange regular expressions on @command{ps} output? + +@example +ps -ef | grep '[c]ron' +@end example + +If the pattern had been written without the square brackets, it would +have matched not only the @command{ps} output line for @command{cron}, +but also the @command{ps} output line for @command{grep}. +Note that on some platforms, +@command{ps} limits the output to the width of the screen; +@command{grep} does not have any limit on the length of a line +except the available memory. + +@item +Why does @command{grep} report ``Binary file matches''? + +If @command{grep} listed all matching ``lines'' from a binary file, it +would probably generate output that is not useful, and it might even +muck up your display. +So GNU @command{grep} suppresses output from +files that appear to be binary files. +To force GNU @command{grep} +to output lines even from files that appear to be binary, use the +@option{-a} or @samp{--binary-files=text} option. +To eliminate the +``Binary file matches'' messages, use the @option{-I} or +@samp{--binary-files=without-match} option, +or the @option{-s} or @option{--no-messages} option. + +@item +Why doesn't @samp{grep -lv} print non-matching file names? + +@samp{grep -lv} lists the names of all files containing one or more +lines that do not match. +To list the names of all files that contain no +matching lines, use the @option{-L} or @option{--files-without-match} +option. + +@item +I can do ``OR'' with @samp{|}, but what about ``AND''? + +@example +grep 'paul' /etc/motd | grep 'franc,ois' +@end example + +@noindent +finds all lines that contain both @samp{paul} and @samp{franc,ois}. + +@item +Why does the empty pattern match every input line? + +The @command{grep} command searches for lines that contain strings +that match a pattern. Every line contains the empty string, so an +empty pattern causes @command{grep} to find a match on each line. It +is not the only such pattern: @samp{^}, @samp{$}, and many +other patterns cause @command{grep} to match every line. + +To match empty lines, use the pattern @samp{^$}. To match blank +lines, use the pattern @samp{^[[:blank:]]*$}. To match no lines at +all, use the command @samp{grep -f /dev/null}. + +@item +How can I search in both standard input and in files? + +Use the special file name @samp{-}: + +@example +cat /etc/passwd | grep 'alain' - /etc/motd +@end example + +@item +Why is this back-reference failing? + +@example +echo 'ba' | grep -E '(a)\1|b\1' +@end example + +This outputs an error message, because the second @samp{\1} +has nothing to refer back to, meaning it will never match anything. + +@item +How can I match across lines? + +Standard grep cannot do this, as it is fundamentally line-based. +Therefore, merely using the @code{[:space:]} character class does not +match newlines in the way you might expect. + +With the GNU @command{grep} option @option{-z} (@option{--null-data}), each +input and output ``line'' is null-terminated; @pxref{Other Options}. Thus, +you can match newlines in the input, but typically if there is a match +the entire input is output, so this usage is often combined with +output-suppressing options like @option{-q}, e.g.: + +@example +printf 'foo\nbar\n' | grep -z -q 'foo[[:space:]]\+bar' +@end example + +If this does not suffice, you can transform the input +before giving it to @command{grep}, or turn to @command{awk}, +@command{sed}, @command{perl}, or many other utilities that are +designed to operate across lines. + +@item +What do @command{grep}, @command{fgrep}, and @command{egrep} stand for? + +The name @command{grep} comes from the way line editing was done on Unix. +For example, +@command{ed} uses the following syntax +to print a list of matching lines on the screen: + +@example +global/regular expression/print +g/re/p +@end example + +@command{fgrep} stands for Fixed @command{grep}; +@command{egrep} stands for Extended @command{grep}. + +@end enumerate + + +@node Performance +@chapter Performance + +@cindex performance +Typically @command{grep} is an efficient way to search text. However, +it can be quite slow in some cases, and it can search large files +where even minor performance tweaking can help significantly. +Although the algorithm used by @command{grep} is an implementation +detail that can change from release to release, understanding its +basic strengths and weaknesses can help you improve its performance. + +The @command{grep} command operates partly via a set of automata that +are designed for efficiency, and partly via a slower matcher that +takes over when the fast matchers run into unusual features like +back-references. When feasible, the Boyer--Moore fast string +searching algorithm is used to match a single fixed pattern, and the +Aho--Corasick algorithm is used to match multiple fixed patterns. + +@cindex locales +Generally speaking @command{grep} operates more efficiently in +single-byte locales, since it can avoid the special processing needed +for multi-byte characters. If your patterns will work just as well +that way, setting @env{LC_ALL} to a single-byte locale can help +performance considerably. Setting @samp{LC_ALL='C'} can be +particularly efficient, as @command{grep} is tuned for that locale. + +@cindex case insensitive search +Outside the @samp{C} locale, case-insensitive search, and search for +bracket expressions like @samp{[a-z]} and @samp{[[=a=]b]}, can be +surprisingly inefficient due to difficulties in fast portable access to +concepts like multi-character collating elements. + +@cindex back-references +A back-reference such as @samp{\1} can hurt performance significantly +in some cases, since back-references cannot in general be implemented +via a finite state automaton, and instead trigger a backtracking +algorithm that can be quite inefficient. For example, although the +pattern @samp{^(.*)\1@{14@}(.*)\2@{13@}$} matches only lines whose +lengths can be written as a sum @math{15x + 14y} for nonnegative +integers @math{x} and @math{y}, the pattern matcher does not perform +linear Diophantine analysis and instead backtracks through all +possible matching strings, using an algorithm that is exponential in +the worst case. + +@cindex holes in files +On some operating systems that support files with holes---large +regions of zeros that are not physically present on secondary +storage---@command{grep} can skip over the holes efficiently without +needing to read the zeros. This optimization is not available if the +@option{-a} (@option{--binary-files=text}) option is used (@pxref{File and +Directory Selection}), unless the @option{-z} (@option{--null-data}) +option is also used (@pxref{Other Options}). + +For more about the algorithms used by @command{grep} and about +related string matching algorithms, see: + +@frenchspacing on +@itemize @bullet +@item +Aho AV.

Also, the POSIX specification for +back-references is at times unclear. Furthermore, many regular +expression implementations have back-reference bugs that can cause +programs to return incorrect answers or even crash, and fixing these +bugs has often been low-priority: for example, as of 2021 the +@url{https://sourceware.org/bugzilla/,GNU C library bug database} +contained back-reference bugs +@url{https://sourceware.org/bugzilla/show_bug.cgi?id=52,,52}, +@url{https://sourceware.org/bugzilla/show_bug.cgi?id=10844,,10844}, +@url{https://sourceware.org/bugzilla/show_bug.cgi?id=11053,,11053}, +@url{https://sourceware.org/bugzilla/show_bug.cgi?id=24269,,24269} +and @url{https://sourceware.org/bugzilla/show_bug.cgi?id=25322,,25322}, +with little sign of forthcoming fixes.

Declaring FUNCTION with a different + signature in C is a compilation error, so this macro must use the + same type as any existing declaration so that programs that avoid + the problematic FUNCTION do not fail to compile merely because they + included a header that poisoned the function. But this implies that + _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already + have a declaration. Use of this macro implies that there must not + be any other macro hiding the declaration of FUNCTION; but + undefining FUNCTION first is part of the poisoning process anyway + (although for symbols that are provided only via a macro, the result + is a compilation error rather than a warning containing + "literal string"). Also note that in C++, it is only safe to use if + FUNCTION has no overloads. + + For an example, it is possible to poison 'getline' by: + - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]], + [getline]) in configure.ac, which potentially defines + HAVE_RAW_DECL_GETLINE + - adding this code to a header that wraps the system <stdio.h>: + #undef getline + #if HAVE_RAW_DECL_GETLINE + _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but" + "not universally present; use the gnulib module getline"); + #endif + + It is not possible to directly poison global variables. But it is + possible to write a wrapper accessor function, and poison that + (less common usage, like &environ, will cause a compilation error + rather than issue the nice warning, but the end result of informing + the developer about their portability problem is still achieved): + #if HAVE_RAW_DECL_ENVIRON + static char *** + rpl_environ (void) { return &environ; } + _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared"); + # undef environ + # define environ (*rpl_environ ()) + #endif + or better (avoiding contradictory use of 'static' and 'extern'): + #if HAVE_RAW_DECL_ENVIRON + static char *** + _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared") + rpl_environ (void) { return &environ; } + # undef environ + # define environ (*rpl_environ ()) + #endif + */ +#ifndef _GL_WARN_ON_USE + +# if 4 < __GNUC__ || (__GNUC__ == 4 && 3 <= __GNUC_MINOR__) +/* A compiler attribute is available in gcc versions 4.3.0 and later. */ +# define _GL_WARN_ON_USE(function, message) \ +extern __typeof__ (function) function __attribute__ ((__warning__ (message))) +# define _GL_WARN_ON_USE_ATTRIBUTE(message) \ + __attribute__ ((__warning__ (message))) +# elif __clang_major__ >= 4 +/* Another compiler attribute is available in clang. */ +# define _GL_WARN_ON_USE(function, message) \ +extern __typeof__ (function) function \ + __attribute__ ((__diagnose_if__ (1, message, "warning"))) +# define _GL_WARN_ON_USE_ATTRIBUTE(message) \ + __attribute__ ((__diagnose_if__ (1, message, "warning"))) +# elif __GNUC__ >= 3 && GNULIB_STRICT_CHECKING +/* Verify the existence of the function. */ +# define _GL_WARN_ON_USE(function, message) \ +extern __typeof__ (function) function +# define _GL_WARN_ON_USE_ATTRIBUTE(message) +# else /* Unsupported. */ +# define _GL_WARN_ON_USE(function, message) \ +_GL_WARN_EXTERN_C int _gl_warn_on_use +# define _GL_WARN_ON_USE_ATTRIBUTE(message) +# endif +#endif + +/* _GL_WARN_ON_USE_CXX (function, rettype_gcc, rettype_clang, parameters_and_attributes, "message") + is like _GL_WARN_ON_USE (function, "message"), except that in C++ mode the + function is declared with the given prototype, consisting of return type, + parameters, and attributes. + This variant is useful for overloaded functions in C++. _GL_WARN_ON_USE does + not work in this case. */ +#ifndef _GL_WARN_ON_USE_CXX +# if !defined __cplusplus +# define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ + _GL_WARN_ON_USE (function, msg) +# else +# if 4 < __GNUC__ || (__GNUC__ == 4 && 3 <= __GNUC_MINOR__) +/* A compiler attribute is available in gcc versions 4.3.0 and later. */ +# define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ +extern rettype_gcc function parameters_and_attributes \ + __attribute__ ((__warning__ (msg))) +# elif __clang_major__ >= 4 +/* Another compiler attribute is available in clang. */ +# define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ +extern rettype_clang function parameters_and_attributes \ + __attribute__ ((__diagnose_if__ (1, msg, "warning"))) +# elif __GNUC__ >= 3 && GNULIB_STRICT_CHECKING +/* Verify the existence of the function. */ +# define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ +extern rettype_gcc function parameters_and_attributes +# else /* Unsupported. */ +# define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ +_GL_WARN_EXTERN_C int _gl_warn_on_use +# endif +# endif +#endif + +/* _GL_WARN_EXTERN_C declaration; + performs the declaration with C linkage. */ +#ifndef _GL_WARN_EXTERN_C +# if defined __cplusplus +# define _GL_WARN_EXTERN_C extern "C" +# else +# define _GL_WARN_EXTERN_C extern +# endif +#endif diff --git a/src/grep/gnulib-tests/windows-thread.c b/src/grep/gnulib-tests/windows-thread.c new file mode 100644 index 0000000..a60967f --- /dev/null +++ b/src/grep/gnulib-tests/windows-thread.c @@ -0,0 +1,243 @@ +/* Creating and controlling threads (native Windows implementation). + Copyright (C) 2005-2021 Free Software Foundation, Inc. + + This file is free software: you can redistribute it and/or modify + it under the terms of the GNU Lesser General Public License as + published by the Free Software Foundation; either version 2.1 of the + License, or (at your option) any later version. + + This file is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

All the + macros defined in mbchar.h can be used on it. + + mbui_cur_ptr (iter) + return a pointer to the beginning of the current multibyte character. + + mbui_reloc (iter, ptrdiff) + relocates iterator when the string is moved by ptrdiff bytes. + + mbui_copy (&destiter, &srciter) + copies srciter to destiter. + + Here are the function prototypes of the macros. + + extern void mbui_init (mbui_iterator_t iter, const char *startptr); + extern bool mbui_avail (mbui_iterator_t iter); + extern void mbui_advance (mbui_iterator_t iter); + extern mbchar_t mbui_cur (mbui_iterator_t iter); + extern const char * mbui_cur_ptr (mbui_iterator_t iter); + extern void mbui_reloc (mbui_iterator_t iter, ptrdiff_t ptrdiff); + extern void mbui_copy (mbui_iterator_t *new, const mbui_iterator_t *old); + */ + +#ifndef _MBUITER_H +#define _MBUITER_H 1 + +#include <assert.h> +#include <stdbool.h> +#include <stddef.h> +#include <stdlib.h> +#include <string.h> +#include <wchar.h> + +#include "mbchar.h" +#include "strnlen1.h" + +#ifndef _GL_INLINE_HEADER_BEGIN + #error "Please include config.h first." +#endif +_GL_INLINE_HEADER_BEGIN +#ifndef MBUITER_INLINE +# define MBUITER_INLINE _GL_INLINE +#endif + +struct mbuiter_multi +{ + bool in_shift; /* true if next byte may not be interpreted as ASCII */ + mbstate_t state; /* if in_shift: current shift state */ + bool next_done; /* true if mbui_avail has already filled the following */ + struct mbchar cur; /* the current character: + const char *cur.ptr pointer to current character + The following are only valid after mbui_avail. + size_t cur.bytes number of bytes of current character + bool cur.wc_valid true if wc is a valid wide character + wchar_t cur.wc if wc_valid: the current character + */ +}; + +MBUITER_INLINE void +mbuiter_multi_next (struct mbuiter_multi *iter) +{ + if (iter->next_done) + return; + if (iter->in_shift) + goto with_shift; + /* Handle most ASCII characters quickly, without calling mbrtowc(). */ + if (is_basic (*iter->cur.ptr)) + { + /* These characters are part of the basic character set.

The idea + is that you would use these pre-tested macros to solve a + very specific set of problems, and they would run fast. + Caution: no side-effects in arguments please!! They may be + evaluated MANY times!! + + These macros operate a stack of objects. Each object starts life + small, and may grow to maturity. (Consider building a word syllable + by syllable.) An object can move while it is growing. Once it has + been "finished" it never changes address again. So the "top of the + stack" is typically an immature growing object, while the rest of the + stack is of mature, fixed size and fixed address objects. + + These routines grab large chunks of memory, using a function you + supply, called 'obstack_chunk_alloc'. On occasion, they free chunks, + by calling 'obstack_chunk_free'. You must define them and declare + them before using any obstack macros. + + Each independent stack is represented by a 'struct obstack'. + Each of the obstack macros expects a pointer to such a structure + as the first argument. + + One motivation for this package is the problem of growing char strings + in symbol tables. Unless you are "fascist pig with a read-only mind" + --Gosper's immortal quote from HAKMEM item 154, out of context--you + would not like to put any arbitrary upper limit on the length of your + symbols. + + In practice this often means you will build many short symbols and a + few long symbols. At the time you are reading a symbol you don't know + how long it is. One traditional method is to read a symbol into a + buffer, realloc()ating the buffer every time you try to read a symbol + that is longer than the buffer. This is beaut, but you still will + want to copy the symbol from the buffer to a more permanent + symbol-table entry say about half the time. + + With obstacks, you can work differently. Use one obstack for all symbol + names. As you read a symbol, grow the name in the obstack gradually. + When the name is complete, finalize it. Then, if the symbol exists already, + free the newly read name. + + The way we do this is to take a large chunk, allocating memory from + low addresses. When you want to build a symbol in the chunk you just + add chars above the current "high water mark" in the chunk. When you + have finished adding chars, because you got to the end of the symbol, + you know how long the chars are, and you can create a new object. + Mostly the chars will not burst over the highest address of the chunk, + because you would typically expect a chunk to be (say) 100 times as + long as an average object. + + In case that isn't clear, when we have enough chars to make up + the object, THEY ARE ALREADY CONTIGUOUS IN THE CHUNK (guaranteed) + so we just point to it where it lies. No moving of chars is + needed and this is the second win: potentially long strings need + never be explicitly shuffled. Once an object is formed, it does not + change its address during its lifetime. + + When the chars burst over a chunk boundary, we allocate a larger + chunk, and then copy the partly formed object from the end of the old + chunk to the beginning of the new larger chunk. We then carry on + accreting characters to the end of the object as we normally would. + + A special macro is provided to add a single char at a time to a + growing object. This allows the use of register variables, which + break the ordinary 'growth' macro. + + Summary: + We allocate large chunks. + We carve out one object at a time from the current chunk. + Once carved, an object never moves. + We are free to append data of any size to the currently + growing object. + Exactly one object is growing in an obstack at any one time. + You can run one obstack per control block. + You may have as many control blocks as you dare. + Because of the way we do it, you can "unwind" an obstack + back to a previous state. (You may remove objects much + as you would with a stack.) + */ + + +/* Don't do the contents of this file more than once. */ + +#ifndef _OBSTACK_H +#define _OBSTACK_H 1 + +#ifndef _OBSTACK_INTERFACE_VERSION +# define _OBSTACK_INTERFACE_VERSION 2 +#endif + +#include <stddef.h> /* For size_t and ptrdiff_t. */ +#include <string.h> /* For __GNU_LIBRARY__, and memcpy. */ + +#if __STDC_VERSION__ < 199901L || defined __HP_cc +# define __FLEXIBLE_ARRAY_MEMBER 1 +#else +# define __FLEXIBLE_ARRAY_MEMBER +#endif + +#if _OBSTACK_INTERFACE_VERSION == 1 +/* For binary compatibility with obstack version 1, which used "int" + and "long" for these two types. */ +# define _OBSTACK_SIZE_T unsigned int +# define _CHUNK_SIZE_T unsigned long +# define _OBSTACK_CAST(type, expr) ((type) (expr)) +#else +/* Version 2 with sane types, especially for 64-bit hosts. */ +# define _OBSTACK_SIZE_T size_t +# define _CHUNK_SIZE_T size_t +# define _OBSTACK_CAST(type, expr) (expr) +#endif + +/* If B is the base of an object addressed by P, return the result of + aligning P to the next multiple of A + 1.

If the compiler does not support this + feature, the macro expands to an unused extern declaration. + + _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the + attribute used in _GL_WARN_ON_USE. If the compiler does not support + this feature, it expands to empty. + + These macros are useful for marking a function as a potential + portability trap, with the intent that "literal string" include + instructions on the replacement function that should be used + instead. + _GL_WARN_ON_USE is for functions with 'extern' linkage. + _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline' + linkage. + + However, one of the reasons that a function is a portability trap is + if it has the wrong signature. Declaring FUNCTION with a different + signature in C is a compilation error, so this macro must use the + same type as any existing declaration so that programs that avoid + the problematic FUNCTION do not fail to compile merely because they + included a header that poisoned the function. But this implies that + _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already + have a declaration. Use of this macro implies that there must not + be any other macro hiding the declaration of FUNCTION; but + undefining FUNCTION first is part of the poisoning process anyway + (although for symbols that are provided only via a macro, the result + is a compilation error rather than a warning containing + "literal string"). Also note that in C++, it is only safe to use if + FUNCTION has no overloads. + + For an example, it is possible to poison 'getline' by: + - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]], + [getline]) in configure.ac, which potentially defines + HAVE_RAW_DECL_GETLINE + - adding this code to a header that wraps the system <stdio.h>: + #undef getline + #if HAVE_RAW_DECL_GETLINE + _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but" + "not universally present; use the gnulib module getline"); + #endif + + It is not possible to directly poison global variables.

as long as this notice is preserved. + +dnl From Bruno Haible and Sam Steingold. + +dnl Sets the HOST_CPU variable to the canonical name of the CPU. +dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its +dnl C language ABI (application binary interface). +dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in +dnl config.h. +dnl +dnl This canonical name can be used to select a particular assembly language +dnl source file that will interoperate with C code on the given host. +dnl +dnl For example: +dnl * 'i386' and 'sparc' are different canonical names, because code for i386 +dnl will not run on SPARC CPUs and vice versa. They have different +dnl instruction sets. +dnl * 'sparc' and 'sparc64' are different canonical names, because code for +dnl 'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code +dnl contains 32-bit instructions, whereas 'sparc64' code contains 64-bit +dnl instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit +dnl mode, but not both. +dnl * 'mips' and 'mipsn32' are different canonical names, because they use +dnl different argument passing and return conventions for C functions, and +dnl although the instruction set of 'mips' is a large subset of the +dnl instruction set of 'mipsn32'. +dnl * 'mipsn32' and 'mips64' are different canonical names, because they use +dnl different sizes for the C types like 'int' and 'void *', and although +dnl the instruction sets of 'mipsn32' and 'mips64' are the same. +dnl * The same canonical name is used for different endiannesses. You can +dnl determine the endianness through preprocessor symbols: +dnl - 'arm': test __ARMEL__. +dnl - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL. +dnl - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN. +dnl * The same name 'i386' is used for CPUs of type i386, i486, i586 +dnl (Pentium), AMD K7, Pentium II, Pentium IV, etc., because +dnl - Instructions that do not exist on all of these CPUs (cmpxchg, +dnl MMX, SSE, SSE2, 3DNow! etc.) are not frequently used.
