2001, 2002, 2007, 2008 Free Software Foundation, Inc. +@uref{http://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 the Document already +includes a cover text for the same cover, previously added by you or +by arrangement made by the same entity you are acting on behalf of, +you may not add another; but you may replace the old one, on explicit +permission from the previous publisher that added the old one. + +The author(s) and publisher(s) of the Document do not by this License +give permission to use their names for publicity for or to assert or +imply endorsement of any Modified Version. + +@item +COMBINING DOCUMENTS + +You may combine the Document with other documents released under this +License, under the terms defined in section 4 above for modified +versions, provided that you include in the combination all of the +Invariant Sections of all of the original documents, unmodified, and +list them all as Invariant Sections of your combined work in its +license notice, and that you preserve all their Warranty Disclaimers. + +The combined work need only contain one copy of this License, and +multiple identical Invariant Sections may be replaced with a single +copy. If there are multiple Invariant Sections with the same name but +different contents, make the title of each such section unique by +adding at the end of it, in parentheses, the name of the original +author or publisher of that section if known, or else a unique number. +Make the same adjustment to the section titles in the list of +Invariant Sections in the license notice of the combined work. + +In the combination, you must combine any sections Entitled ``History'' +in the various original documents, forming one section Entitled +``History''; likewise combine any sections Entitled ``Acknowledgements'', +and any sections Entitled ``Dedications''. You must delete all +sections Entitled ``Endorsements.'' + +@item +COLLECTIONS OF DOCUMENTS + +You may make a collection consisting of the Document and other documents +released under this License, and replace the individual copies of this +License in the various documents with a single copy that is included in +the collection, provided that you follow the rules of this License for +verbatim copying of each of the documents in all other respects. + +You may extract a single document from such a collection, and distribute +it individually under this License, provided you insert a copy of this +License into the extracted document, and follow this License in all +other respects regarding verbatim copying of that document. + +@item +AGGREGATION WITH INDEPENDENT WORKS + +A compilation of the Document or its derivatives with other separate +and independent documents or works, in or on a volume of a storage or +distribution medium, is called an ``aggregate'' if the copyright +resulting from the compilation is not used to limit the legal rights +of the compilation's users beyond what the individual works permit. +When the Document is included in an aggregate, this License does not +apply to the other works in the aggregate which are not themselves +derivative works of the Document. + +If the Cover Text requirement of section 3 is applicable to these +copies of the Document, then if the Document is less than one half of +the entire aggregate, the Document's Cover Texts may be placed on +covers that bracket the Document within the aggregate, or the +electronic equivalent of covers if the Document is in electronic form. +Otherwise they must appear on printed covers that bracket the whole +aggregate. + +@item +TRANSLATION + +Translation is considered a kind of modification, so you may +distribute translations of the Document under the terms of section 4. +Replacing Invariant Sections with translations requires special +permission from their copyright holders, but you may include +translations of some or all Invariant Sections in addition to the +original versions of these Invariant Sections. You may include a +translation of this License, and all the license notices in the +Document, and any Warranty Disclaimers, provided that you also include +the original English version of this License and the original versions +of those notices and disclaimers. In case of a disagreement between +the translation and the original version of this License or a notice +or disclaimer, the original version will prevail. + +If a section in the Document is Entitled ``Acknowledgements'', +``Dedications'', or ``History'', the requirement (section 4) to Preserve +its Title (section 1) will typically require changing the actual +title. + +@item +TERMINATION + +You may not copy, modify, sublicense, or distribute the Document +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense, or distribute it is void, and +will automatically terminate your rights under this License. + +However, if you cease all violation of this License, then your license +from a particular copyright holder is reinstated (a) provisionally, +unless and until the copyright holder explicitly and finally +terminates your license, and (b) permanently, if the copyright holder +fails to notify you of the violation by some reasonable means prior to +60 days after the cessation. + +Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + +Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, receipt of a copy of some or all of the same material does +not give you any rights to use it. + +@item +FUTURE REVISIONS OF THIS LICENSE + +The Free Software Foundation may publish new, revised versions +of the GNU Free Documentation License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. See +@uref{http://www.gnu.org/copyleft/}. + +Each version of the License is given a distinguishing version number. +If the Document specifies that a particular numbered version of this +License ``or any later version'' applies to it, you have the option of +following the terms and conditions either of that specified version or +of any later version that has been published (not as a draft) by the +Free Software Foundation. If the Document does not specify a version +number of this License, you may choose any version ever published (not +as a draft) by the Free Software Foundation.

Whenever possible, each file is replaced by one with the +extension ‘.gz’, while keeping the same ownership modes, access and +modification times. (The default extension is ‘-gz’ for VMS, ‘z’ for +MSDOS, OS/2 FAT and Atari.) If no files are specified or if a file name +is ‘-’, the standard input is compressed to the standard output. ‘gzip’ +will only attempt to compress regular files. In particular, it will +ignore symbolic links. + + If the new file name is too long for its file system, ‘gzip’ +truncates it. ‘gzip’ attempts to truncate only the parts of the file +name longer than 3 characters. (A part is delimited by dots.) If the +name consists of small parts only, the longest parts are truncated. For +example, if file names are limited to 14 characters, gzip.msdos.exe is +compressed to gzi.msd.exe.gz. Names are not truncated on systems which +do not have a limit on file name length. + + By default, ‘gzip’ keeps the original file name and time stamp in the +compressed file. These are used when decompressing the file with the +‘-N’ option. This is useful when the compressed file name was truncated +or when the time stamp was not preserved after a file transfer. +However, due to limitations in the current ‘gzip’ file format, +fractional seconds are discarded. Also, time stamps must fall within +the range 1970-01-01 00:00:00 through 2106-02-07 06:28:15 UTC, and hosts +whose operating systems use 32-bit time stamps are further restricted to +time stamps no later than 2038-01-19 03:14:07 UTC. The upper bounds +assume the typical case where leap seconds are ignored. + + Compressed files can be restored to their original form using ‘gzip +-d’ or ‘gunzip’ or ‘zcat’. If the original name saved in the compressed +file is not suitable for its file system, a new name is constructed from +the original one to make it legal. + + ‘gunzip’ takes a list of files on its command line and replaces each +file whose name ends with ‘.gz’, ‘.z’ ‘-gz’, ‘-z’, or ‘_z’ (ignoring +case) and which begins with the correct magic number with an +uncompressed file without the original extension. ‘gunzip’ also +recognizes the special extensions ‘.tgz’ and ‘.taz’ as shorthands for +‘.tar.gz’ and ‘.tar.Z’ respectively. When compressing, ‘gzip’ uses the +‘.tgz’ extension if necessary instead of truncating a file with a ‘.tar’ +extension. + + ‘gunzip’ can currently decompress files created by ‘gzip’, ‘zip’, +‘compress’ or ‘pack’. The detection of the input format is automatic. +When using the first two formats, ‘gunzip’ checks a 32 bit CRC (cyclic +redundancy check). For ‘pack’, ‘gunzip’ checks the uncompressed length. +The ‘compress’ format was not designed to allow consistency checks. +However ‘gunzip’ is sometimes able to detect a bad ‘.Z’ file. If you +get an error when uncompressing a ‘.Z’ file, do not assume that the ‘.Z’ +file is correct simply because the standard ‘uncompress’ does not +complain. This generally means that the standard ‘uncompress’ does not +check its input, and happily generates garbage output. The SCO +‘compress -H’ format (LZH compression method) does not include a CRC but +also allows some consistency checks. + + Files created by ‘zip’ can be uncompressed by ‘gzip’ only if they +have a single member compressed with the “deflation” method. This +feature is only intended to help conversion of ‘tar.zip’ files to the +‘tar.gz’ format. To extract a ‘zip’ file with a single member, use a +command like ‘gunzip <foo.zip’ or ‘gunzip -S .zip foo.zip’. To extract +‘zip’ files with several members, use ‘unzip’ instead of ‘gunzip’. + + ‘zcat’ is identical to ‘gunzip -c’. ‘zcat’ uncompresses either a +list of files on the command line or its standard input and writes the +uncompressed data on standard output. ‘zcat’ will uncompress files that +have the correct magic number whether they have a ‘.gz’ suffix or not. + + ‘gzip’ uses the Lempel–Ziv algorithm used in ‘zip’ and PKZIP. The +amount of compression obtained depends on the size of the input and the +distribution of common substrings. Typically, text such as source code +or English is reduced by 60–70%. Compression is generally much better +than that achieved by LZW (as used in ‘compress’), Huffman coding (as +used in ‘pack’), or adaptive Huffman coding (‘compact’). + + Compression is always performed, even if the compressed file is +slightly larger than the original. The worst case expansion is a few +bytes for the ‘gzip’ file header, plus 5 bytes every 32K block, or an +expansion ratio of 0.015% for large files. Note that the actual number +of used disk blocks almost never increases. ‘gzip’ normally preserves +the mode, ownership and time stamps of files when compressing or +decompressing. + + The ‘gzip’ file format is specified in P. Deutsch, GZIP file format +specification version 4.3, Internet RFC 1952 +(http://www.ietf.org/rfc/rfc1952.txt) (May 1996). The ‘zip’ deflation +format is specified in P.

If + there are several input files, the output consists of a sequence of + independently compressed members. To obtain better compression, + concatenate all input files before compressing them. + +‘--decompress’ +‘--uncompress’ +‘-d’ + Decompress. + +‘--force’ +‘-f’ + Force compression or decompression even if the file has multiple + links or the corresponding file already exists, or if the + compressed data is read from or written to a terminal. If the + input data is not in a format recognized by ‘gzip’, and if the + option ‘--stdout’ is also given, copy the input data without change + to the standard output: let ‘zcat’ behave as ‘cat’. If ‘-f’ is not + given, and when not running in the background, ‘gzip’ prompts to + verify whether an existing file should be overwritten. + +‘--help’ +‘-h’ + Print an informative help message describing the options then quit. + +‘--keep’ +‘-k’ + Keep (don’t delete) input files during compression or + decompression. + +‘--list’ +‘-l’ + For each compressed file, list the following fields: + + compressed size: size of the compressed file + uncompressed size: size of the uncompressed file + ratio: compression ratio (0.0% if unknown) + uncompressed_name: name of the uncompressed file + + The uncompressed size is given as −1 for files not in ‘gzip’ + format, such as compressed ‘.Z’ files. To get the uncompressed + size for such a file, you can use: + + zcat file.Z | wc -c + + In combination with the ‘--verbose’ option, the following fields + are also displayed: + + method: compression method (deflate,compress,lzh,pack) + crc: the 32-bit CRC of the uncompressed data + date & time: time stamp for the uncompressed file + + The CRC is given as ffffffff for a file not in gzip format. + + With ‘--verbose’, the size totals and compression ratio for all + files is also displayed, unless some sizes are unknown. With + ‘--quiet’, the title and totals lines are not displayed. + + The ‘gzip’ format represents the input size modulo 2^32, so the + uncompressed size and compression ratio are listed incorrectly for + uncompressed files 4 GiB and larger. To work around this problem, + you can use the following command to discover a large uncompressed + file’s true size: + + zcat file.gz | wc -c + +‘--license’ +‘-L’ + Display the ‘gzip’ license then quit. + +‘--no-name’ +‘-n’ + When compressing, do not save the original file name and time stamp + by default. (The original name is always saved if the name had to + be truncated.) When decompressing, do not restore the original + file name if present (remove only the ‘gzip’ suffix from the + compressed file name) and do not restore the original time stamp if + present (copy it from the compressed file). This option is the + default when decompressing. + +‘--name’ +‘-N’ + When compressing, always save the original file name and time + stamp; this is the default. When decompressing, restore the + original file name and time stamp if present. This option is + useful on systems which have a limit on file name length or when + the time stamp has been lost after a file transfer. + +‘--quiet’ +‘-q’ + Suppress all warning messages. + +‘--recursive’ +‘-r’ + Travel the directory structure recursively. If any of the file + names specified on the command line are directories, ‘gzip’ will + descend into the directory and compress all the files it finds + there (or decompress them in the case of ‘gunzip’). + +‘--rsyncable’ + Cater better to the ‘rsync’ program by periodically resetting the + internal structure of the compressed data stream. This lets the + ‘rsync’ program take advantage of similarities in the uncompressed + input when synchronizing two files compressed with this flag. The + cost: the compressed output is usually about one percent larger. + +‘--suffix SUF’ +‘-S SUF’ + Use suffix SUF instead of ‘.gz’. Any suffix can be given, but + suffixes other than ‘.z’ and ‘.gz’ should be avoided to avoid + confusion when files are transferred to other systems. A null + suffix forces gunzip to try decompression on all given files + regardless of suffix, as in: + + gunzip -S "" * (*.* for MSDOS) + + Previous versions of gzip used the ‘.z’ suffix. This was changed + to avoid a conflict with ‘pack’. + +‘--synchronous’ + Use synchronous output, by transferring output data to the output + file’s storage device when the file system supports this. Because + file system data can be cached, without this option if the system + crashes around the time a command like ‘gzip FOO’ is run the user + might lose both ‘FOO’ and ‘FOO.gz’; this is the default with + ‘gzip’, just as it is the default with most applications that move + data. When this option is used, ‘gzip’ is safer but can be + considerably slower. + +‘--test’ +‘-t’ + Test. Check the compressed file integrity. + +‘--verbose’ +‘-v’ + Verbose. Display the name and percentage reduction for each file + compressed. + +‘--version’ +‘-V’ + Version. Display the version number and compilation options, then + quit. + +‘--fast’ +‘--best’ +‘-N’ + Regulate the speed of compression using the specified digit N, + where ‘-1’ or ‘--fast’ indicates the fastest compression method + (less compression) and ‘--best’ or ‘-9’ indicates the slowest + compression method (optimal compression). The default compression + level is ‘-6’ (that is, biased towards high compression at expense + of speed). + + +File: gzip.info-t, Node: Advanced usage, Next: Environment, Prev: Invoking gzip, Up: Top + +4 Advanced usage +**************** + +Multiple compressed files can be concatenated. In this case, ‘gunzip’ +will extract all members at once. If one member is damaged, other +members might still be recovered after removal of the damaged member. +Better compression can be usually obtained if all members are +decompressed and then recompressed in a single step. + + This is an example of concatenating ‘gzip’ files: + + gzip -c file1 > foo.gz + gzip -c file2 >> foo.gz + +Then + + gunzip -c foo + +is equivalent to + + cat file1 file2 + + In case of damage to one member of a ‘.gz’ file, other members can +still be recovered (if the damaged member is removed). However, you can +get better compression by compressing all members at once: + + cat file1 file2 | gzip > foo.gz + +compresses better than + + gzip -c file1 file2 > foo.gz + + If you want to recompress concatenated files to get better +compression, do: + + zcat old.gz | gzip > new.gz + + If a compressed file consists of several members, the uncompressed +size and CRC reported by the ‘--list’ option applies to the last member +only. If you need the uncompressed size for all members, you can use: + + zcat file.gz | wc -c + + If you wish to create a single archive file with multiple members so +that members can later be extracted independently, use an archiver such +as ‘tar’ or ‘zip’. GNU ‘tar’ supports the ‘-z’ option to invoke ‘gzip’ +transparently. ‘gzip’ is designed as a complement to ‘tar’, not as a +replacement. + + +File: gzip.info-t, Node: Environment, Next: Tapes, Prev: Advanced usage, Up: Top + +5 Environment +************* + +The obsolescent environment variable ‘GZIP’ can hold a set of default +options for ‘gzip’. These options are interpreted first and can be +overwritten by explicit command line parameters. As this can cause +problems when using scripts, this feature is supported only for options +that are reasonably likely to not cause too much harm, and ‘gzip’ warns +if it is used. This feature will be removed in a future release of +‘gzip’. + + You can use an alias or script instead. For example, if ‘gzip’ is in +the directory ‘/usr/bin’ you can prepend ‘$HOME/bin’ to your ‘PATH’ and +create an executable script ‘$HOME/bin/gzip’ containing the following: + + #! /bin/sh + export PATH=/usr/bin + exec gzip -9 "$@" + + On VMS, the name of the obsolescent environment variable is +‘GZIP_OPT’, to avoid a conflict with the symbol set for invocation of +the program. + + +File: gzip.info-t, Node: Tapes, Next: Problems, Prev: Environment, Up: Top + +6 Using ‘gzip’ on tapes +*********************** + +When writing compressed data to a tape, it is generally necessary to pad +the output with zeroes up to a block boundary. When the data is read +and the whole block is passed to ‘gunzip’ for decompression, ‘gunzip’ +detects that there is extra trailing garbage after the compressed data +and emits a warning by default if the garbage contains nonzero bytes. +You can use the ‘--quiet’ option to suppress the warning. + + +File: gzip.info-t, Node: Problems, Next: GNU Free Documentation License, Prev: Tapes, Up: Top + +7 Reporting Bugs +**************** + +If you find a bug in ‘gzip’, please send electronic mail to +<bug-gzip@gnu.org>.

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

Whenever possible, each file is replaced by one with the +extension @samp{.gz}, while keeping the same ownership modes, access and +modification times. (The default extension is @samp{-gz} for @abbr{VMS}, +@samp{z} for @abbr{MSDOS}, @abbr{OS/2} @abbr{FAT} and Atari.) +If no files are specified or +if a file name is @file{-}, the standard input is compressed to the standard +output. @command{gzip} will only attempt to compress regular files. In +particular, it will ignore symbolic links. + +If the new file name is too long for its file system, @command{gzip} +truncates it. @command{gzip} attempts to truncate only the parts of the +file name longer than 3 characters. (A part is delimited by dots.) If +the name consists of small parts only, the longest parts are truncated. +For example, if file names are limited to 14 characters, gzip.msdos.exe +is compressed to gzi.msd.exe.gz. Names are not truncated on systems +which do not have a limit on file name length. + +By default, @command{gzip} keeps the original file name and time stamp in +the compressed file. These are used when decompressing the file with the +@option{-N} option. This is useful when the compressed file name was +truncated or when the time stamp was not preserved after a file +transfer. However, due to limitations in the current @command{gzip} file +format, fractional seconds are discarded. Also, time stamps must fall +within the range 1970-01-01 00:00:00 through 2106-02-07 06:28:15 +@abbr{UTC}, and hosts whose operating systems use 32-bit time +stamps are further restricted to time stamps no later than 2038-01-19 +03:14:07 @abbr{UTC}. The upper bounds assume the typical case +where leap seconds are ignored. + +Compressed files can be restored to their original form using @samp{gzip -d} +or @command{gunzip} or @command{zcat}. If the original name saved in the +compressed file is not suitable for its file system, a new name is +constructed from the original one to make it legal. + +@command{gunzip} takes a list of files on its command line and replaces +each file whose name ends with @samp{.gz}, @samp{.z} +@samp{-gz}, @samp{-z}, or @samp{_z} (ignoring case) +and which begins with the correct +magic number with an uncompressed file without the original extension. +@command{gunzip} also recognizes the special extensions @samp{.tgz} and +@samp{.taz} as shorthands for @samp{.tar.gz} and @samp{.tar.Z} +respectively. When compressing, @command{gzip} uses the @samp{.tgz} +extension if necessary instead of truncating a file with a @samp{.tar} +extension. + +@command{gunzip} can currently decompress files created by @command{gzip}, +@command{zip}, @command{compress} or @command{pack}. The detection of the input +format is automatic. When using the first two formats, @command{gunzip} +checks a 32 bit @abbr{CRC} (cyclic redundancy check). For @command{pack}, +@command{gunzip} checks the uncompressed length. The @command{compress} format +was not designed to allow consistency checks. However @command{gunzip} is +sometimes able to detect a bad @samp{.Z} file. If you get an error when +uncompressing a @samp{.Z} file, do not assume that the @samp{.Z} file is +correct simply because the standard @command{uncompress} does not complain. +This generally means that the standard @command{uncompress} does not check +its input, and happily generates garbage output. The @abbr{SCO} @samp{compress +-H} format (@abbr{LZH} compression method) does not include a @abbr{CRC} but +also allows some consistency checks. + +Files created by @command{zip} can be uncompressed by @command{gzip} only if +they have a single member compressed with the ``deflation'' method. This +feature is only intended to help conversion of @file{tar.zip} files to +the @file{tar.gz} format. To extract a @command{zip} file with a single +member, use a command like @samp{gunzip <foo.zip} or @samp{gunzip -S +.zip foo.zip}. To extract @command{zip} files with several +members, use @command{unzip} instead of @command{gunzip}. + +@command{zcat} is identical to @samp{gunzip -c}. @command{zcat} +uncompresses either a list of files on the command line or its standard +input and writes the uncompressed data on standard output. @command{zcat} +will uncompress files that have the correct magic number whether they +have a @samp{.gz} suffix or not. + +@command{gzip} uses the Lempel--Ziv algorithm used in @command{zip} and +@abbr{PKZIP}@. +The amount of compression obtained depends on the size of the input and +the distribution of common substrings. Typically, text such as source +code or English is reduced by 60--70%. Compression is generally much +better than that achieved by @abbr{LZW} (as used in @command{compress}), Huffman +coding (as used in @command{pack}), or adaptive Huffman coding +(@command{compact}). + +Compression is always performed, even if the compressed file is slightly +larger than the original. The worst case expansion is a few bytes for +the @command{gzip} file header, plus 5 bytes every 32K block, or an expansion +ratio of 0.015% for large files. Note that the actual number of used +disk blocks almost never increases. @command{gzip} normally preserves the mode, +ownership and time stamps of files when compressing or decompressing. + +The @command{gzip} file format is specified in P. Deutsch, GZIP file +format specification version 4.3, +@uref{http://www.ietf.org/rfc/rfc1952.txt, Internet @abbr{RFC} 1952} (May +1996). The @command{zip} deflation format is specified in P. Deutsch, +DEFLATE Compressed Data Format Specification version 1.3, +@uref{http://www.ietf.org/rfc/rfc1951.txt, Internet @abbr{RFC} 1951} (May +1996). + +@node Sample +@chapter Sample output +@cindex sample + +Here are some realistic examples of running @command{gzip}. + +This is the output of the command @samp{gzip -h}: + +@example +Usage: gzip [OPTION]...

If the input data is not in +a format recognized by @command{gzip}, and if the option @option{--stdout} is also +given, copy the input data without change to the standard output: let +@command{zcat} behave as @command{cat}.

To get the uncompressed size for +such a file, you can use: + +@example +zcat file.Z | wc -c +@end example + +In combination with the @option{--verbose} option, the following fields are also +displayed: + +@example +method: compression method (deflate,compress,lzh,pack) +crc: the 32-bit CRC of the uncompressed data +date & time: time stamp for the uncompressed file +@end example + +The @abbr{CRC} is given as ffffffff for a file not in gzip format. + +With @option{--verbose}, the size totals and compression ratio for all files +is also displayed, unless some sizes are unknown. With @option{--quiet}, +the title and totals lines are not displayed. + +The @command{gzip} format represents the input size modulo +@math{2^32}, so the uncompressed size and compression ratio are listed +incorrectly for uncompressed files 4 GiB and larger. To work around +this problem, you can use the following command to discover a large +uncompressed file's true size: + +@example +zcat file.gz | wc -c +@end example + +@item --license +@itemx -L +Display the @command{gzip} license then quit. + +@item --no-name +@itemx -n +When compressing, do not save the original file name and time stamp by +default. (The original name is always saved if the name had to be +truncated.) When decompressing, do not restore the original file name +if present (remove only the @command{gzip} +suffix from the compressed file name) and do not restore the original +time stamp if present (copy it from the compressed file). This option +is the default when decompressing. + +@item --name +@itemx -N +When compressing, always save the original file name and time stamp; this +is the default. When decompressing, restore the original file name and +time stamp if present. This option is useful on systems which have +a limit on file name length or when the time stamp has been lost after +a file transfer. + +@item --quiet +@itemx -q +Suppress all warning messages. + +@item --recursive +@itemx -r +Travel the directory structure recursively. If any of the file names +specified on the command line are directories, @command{gzip} will descend +into the directory and compress all the files it finds there (or +decompress them in the case of @command{gunzip}). + +@item --rsyncable +Cater better to the @command{rsync} program by periodically resetting +the internal structure of the compressed data stream. This lets the +@code{rsync} program take advantage of similarities in the uncompressed +input when synchronizing two files compressed with this flag. The cost: +the compressed output is usually about one percent larger. + +@item --suffix @var{suf} +@itemx -S @var{suf} +Use suffix @var{suf} instead of @samp{.gz}. Any suffix can be +given, but suffixes other than @samp{.z} and @samp{.gz} should be +avoided to avoid confusion when files are transferred to other systems. +A null suffix forces gunzip to try decompression on all given files +regardless of suffix, as in: + +@example +gunzip -S "" * (*.* for MSDOS) +@end example + +Previous versions of gzip used the @samp{.z} suffix. This was changed to +avoid a conflict with @command{pack}. + +@item --synchronous +Use synchronous output, by transferring output data to the output +file's storage device when the file system supports this. Because +file system data can be cached, without this option if the system +crashes around the time a command like @samp{gzip FOO} is run the user +might lose both @file{FOO} and @file{FOO.gz}; this is the default with +@command{gzip}, just as it is the default with most applications that +move data. When this option is used, @command{gzip} is safer but can +be considerably slower. + +@item --test +@itemx -t +Test. Check the compressed file integrity. + +@item --verbose +@itemx -v +Verbose. Display the name and percentage reduction for each file compressed. + +@item --version +@itemx -V +Version.

The default +compression level is @option{-6} (that is, biased towards high compression at +expense of speed). +@end table + +@node Advanced usage +@chapter Advanced usage +@cindex concatenated files + +Multiple compressed files can be concatenated. In this case, +@command{gunzip} will extract all members at once. If one member is +damaged, other members might still be recovered after removal of the +damaged member. Better compression can be usually obtained if all +members are decompressed and then recompressed in a single step. + +This is an example of concatenating @command{gzip} files: + +@example +gzip -c file1 > foo.gz +gzip -c file2 >> foo.gz +@end example + +@noindent +Then + +@example +gunzip -c foo +@end example + +@noindent +is equivalent to + +@example +cat file1 file2 +@end example + +In case of damage to one member of a @samp{.gz} file, other members can +still be recovered (if the damaged member is removed). However, +you can get better compression by compressing all members at once: + +@example +cat file1 file2 | gzip > foo.gz +@end example + +@noindent +compresses better than + +@example +gzip -c file1 file2 > foo.gz +@end example + +If you want to recompress concatenated files to get better compression, do: + +@example +zcat old.gz | gzip > new.gz +@end example + +If a compressed file consists of several members, the uncompressed +size and @abbr{CRC} reported by the @option{--list} option applies to +the last member +only. If you need the uncompressed size for all members, you can use: + +@example +zcat file.gz | wc -c +@end example + +If you wish to create a single archive file with multiple members so +that members can later be extracted independently, use an archiver such +as @command{tar} or @command{zip}. @acronym{GNU} @command{tar} +supports the @option{-z} +option to invoke @command{gzip} transparently. @command{gzip} is designed as a +complement to @command{tar}, not as a replacement. + +@node Environment +@chapter Environment +@cindex Environment + +The obsolescent environment variable @env{GZIP} can hold a set of +default options for @command{gzip}. These options are interpreted +first and can be overwritten by explicit command line parameters. As +this can cause problems when using scripts, this feature is supported +only for options that are reasonably likely to not cause too much +harm, and @command{gzip} warns if it is used. This feature will be +removed in a future release of @command{gzip}. + +You can use an alias or script instead. For example, if +@command{gzip} is in the directory @samp{/usr/bin} you can prepend +@file{$HOME/bin} to your @env{PATH} and create an executable script +@file{$HOME/bin/gzip} containing the following: + +@example +#! /bin/sh +export PATH=/usr/bin +exec gzip -9 "$@@" +@end example + +On @abbr{VMS}, the name of the obsolescent environment variable is +@env{GZIP_OPT}, to avoid a conflict with the symbol set for invocation +of the program. + +@node Tapes +@chapter Using @command{gzip} on tapes +@cindex tapes + +When writing compressed data to a tape, it is generally necessary to pad +the output with zeroes up to a block boundary. When the data is read and +the whole block is passed to @command{gunzip} for decompression, +@command{gunzip} detects that there is extra trailing garbage after the +compressed data and emits a warning by default if the garbage contains +nonzero bytes. You can use the @option{--quiet} option to suppress +the warning. + +@node Problems +@chapter Reporting Bugs +@cindex bugs + +If you find a bug in @command{gzip}, please send electronic mail to +@email{bug-gzip@@gnu.org}.
