By +default, each line read from a file list is first stripped off the +leading and trailing whitespace and, if the result begins with a dash, +it is treated as tar command line option. + +Use the --verbatim-files-from option to disable this special handling. +This facilitates the use of tar with file lists created automatically +(e.g. by find(1) command). + +This option affects all --files-from options that occur after it in +the command line. Its effect is reverted by the +--no-verbatim-files-from option. + +* --null option reads file names verbatim + +The --null option implies --verbatim-files-from. I.e. each line +read from null-delimited file lists is treated as a file name. + +This restores the documented behavior, which was broken in version +1.27. + +* New options: --owner-map=FILE and --group-map=FILE + +These two options provide fine-grained control over what user/group +names (or IDs) should be mapped when adding files to archive. + +For both options, FILE is a plain text file with user or group +mappings. Empty lines are ignored. Comments are introduced with +# sign (unless quoted) and extend to the end of the corresponding +line. Each non-empty line defines translation for a single UID (GID). +It must consist of two fields, delimited by any amount of whitespace: + + OLDNAME NEWNAME[:NEWID] + +OLDNAME is either a valid user (group) name or a ID prefixed with +. Unless +NEWID is supplied, NEWNAME must also be either a valid name or a ++ID. Otherwise, both NEWNAME and NEWID need not be listed in the +system user database. + +* New option --clamp-mtime + +The new --clamp-mtime option changes the behavior of --mtime to only +use the time specified if the file mtime is newer than the given time. +The --clamp-mtime option can only be used together with --mtime. + +Typical use case is to make builds reproducible: to loose less +information, it's better to keep the original date of an archive, +except for files modified during the build process. In that case, using +reference (and thus reproducible) timestamps for the latter is good +enough. + +See <https://wiki.debian.org/ReproducibleBuilds> for more information. + +* Deprecated --preserve option removed + +* Sparse file detection + +Tar now uses SEEK_DATA/SEEK_HOLE on systems that support it. This +allows for considerable speed-up in sparse-file detection. + +New option --hole-detection is provided, that allows the user to +select the algorithm used for hole detection. Available arguments +are: + + --hole-detection=seek + Use lseek(2) SEEK_DATA and SEEK_HOLE "whence" parameters. + + --hole-detection=raw + Scan entire file before storing it to determine where holes + are located. + +The default is to use "seek" whenever possible, and fall back to +"raw" otherwise. + + +version 1.28, 2014-07-28 + +* New checkpoint action: totals + +The --checkpoint-action=totals option instructs tar to output the +total number of bytes transferred at each checkpoint. + +* Extended checkpoint format specification. + +New conversion specifiers are implemented. Some of them take +optional arguments, supplied in curly braces between the percent +sign and the specifier letter. + + %d - Number of seconds since tar started. + %{r,w,d}T - I/O totals; optional arguments supply prefixes + to be used before number of bytes read, written and + deleted, correspondingly. + %{FMT}t - Current local time using FMT as strftime(3) format. + If {FMT} is omitted, use %c. + %{N}* - Pad output with spaces to the Nth column, or to the + current screen width, if {N} is not given. + %c - A shortcut for "%{%Y-%m-%d %H:%M:%S}t: %ds, %{read,wrote}T%*\r" + +* New option --one-top-level + +The option --one-top-level tells tar to extract all files into a +subdirectory named by the base name of the archive (minus standard +compression suffixes recognizable by --auto-compress). When used with +an argument, as in --one-top-level=DIR, the files are extracted into the +supplied DIRectory. This ensures that no archive members are +extracted outside of the specified directory, even if the archive is +crafted so as to put them elsewhere. + +* New option --sort + +The --sort=ORDER option instructs tar to sort directory entries +according to ORDER. It takes effect when creating archives. +Available ORDERs are: none (the default), name and inode. The +latter may be absent, if the underlying system does not provide +the necessary information. + +Using --sort=name ensures the member ordering in the created archive +is uniform and reproducible. Using --sort=inode reduces the number +of disk seeks made when creating the archive and thus can considerably +speed up archivation. + +* New exclusion options + + --exclude-ignore=FILE Before dumping a directory check if it + contains FILE, and if so read exclude + patterns for this directory from FILE. + --exclude-ignore-recursive=FILE + Same as above, but the exclusion patterns + read from FILE remain in effect for any + subdirectory, recursively. + --exclude-vcs-ignores Read exclude tags from VCS ignore files, + where such files exist. Supported VCS's + are: CVS, Git, Bazaar, Mercurial. + + +* Tar refuses to read input from and write output to a tty device. + +* Manpages + +This release includes official tar(1) and rmt(8) manpages. +Distribution maintainers are kindly asked to use these instead of the +home-made pages they have been providing so far. + + +version 1.27.1 - Sergey Poznyakoff, 2013-11-17 + +* Bug fixes + +* Fix unquoting of file names obtained via the -T option. + +* Fix GNU long link header timestamp (backward compatibility). + +* Fix extracting sparse members from star archives. + + +version 1.27 - Sergey Poznyakoff, 2013-10-05 + +* Bug fixes + +** Sparse files with large data + +When creating a PAX-format archive, tar no longer arbitrarily restricts +the size of the representation of a sparse file to be less than 8 GiB. + +* Quoting + +In the default C locale, diagnostics and output of 'tar' have been +adjusted to quote 'like this' (with apostrophes) instead of `like this' +(with an accent grave character and an apostrophe). This tracks +recent changes to the GNU coding standards. + +* --owner and --group names and numbers + +The --owner and --group options now accept operands of the form +NAME:NUM, so that you can specify both symbolic name and numeric ID +for owner and group. In these options, NAME no longer needs to be +present in the current host's user and group databases. + +* The --keep-old-files and --skip-old-files options. + +This release restores the traditional functionality of the +--keep-old-files. This option causes tar to avoid replacing +existing files while extracting and to treat such files as errors. +Tar will emit a prominent error message upon encountering such files +and will exit with code 2 when finished extracting the archive. + +A new option --skip-old-files is introduced, which acts exactly as +--keep-old-files, except that it does not treat existing files as +errors. Instead it just silently skips them. An additional level of +verbosity can be obtained by using the option --warning=existing-file +together with this option. + +* Support for POSIX ACLs, extended attributes and SELinux context. + +Starting with this version tar is able to store, extract and list +extended file attributes, POSIX.1e ACLs and SELinux context. This is +controlled by the command line options --xattrs, --acls and --selinux, +correspondingly. Each of these options has a `--no-' counterpart +(e.g. --no-xattrs), which disables the corresponding feature. +Additionally, the options --xattrs-include and --xattrs-exclude allow +you to selectively control for which files to store (or extract) the +extended attributes. + +* Passing command line arguments to external commands. + +Any option taking a command name as its argument now accepts a full +command line as well. Thus, it is now possible to pass additional +arguments to invoked programs. The affected options are: + + --checkpoint-action=exec + -I, --use-compress-program + -F, --info-script + --to-command + +Furthermore, if any additional information is supplied to such a +command via environment variables, these variables can now be used in +the command line itself. Care should be taken to escape them, to +prevent from being expanded too early, for example: + + tar -x -f a.tar --info-script='changevol $TAR_ARCHIVE $TAR_VOLUME' + +* New configure option --enable-gcc-warnings, intended for debugging. + +* New warning control option --warning=[no-]record-size + +On extraction, this option controls whether to display actual record +size, if it differs from the default. + +* New command line option --keep-directory-symlink + +By default, if trying to extract a directory from the archive, +tar discovers that the corresponding file name already exists and is a +symbolic link, it first unlinks the entry, and then extracts the directory. + +This option disables this behavior and instructs tar to follow +symlinks to directories when extracting from the archive. + +It is mainly intended to provide compatibility with the Slackware +installation scripts. + + +version 1.26 - Sergey Poznyakoff, 2011-03-12 + +* Bugfixes + +** Fix the --verify option, which broke in version 1.24. + +** Fix storing long sparse file names in PAX archives. + +** Fix correctness of --atime-preserve=replace + +tar --atime-preserve=replace no longer tries to restore atime of +zero-sized files. + +** Work around POSIX incompatibilities on FreeBSD, NetBSD and Tru64 + +** Fix bug with --one-file-system --listed-incremental + +When invoked with these two options, tar 1.25 would add only the +top-level directory to the archive, but not its contents. + + +version 1.25 - Sergey Poznyakoff, 2010-11-07 + +* Fix extraction of empty directories with the -C option in effect. +* Fix extraction of device nodes. +* Make sure name matching occurs before eventual name transformation. + +Tar 1.24 changed the ordering of name matching and name transformation +so that the former saw already transformed file names. This made it +impossible to match file names in certain cases. It is fixed now. + +* Fix the behavior of tar -x --overwrite on hosts lacking O_NOFOLLOW. + +* Improve the testsuite. + +* Alternative decompression programs. + +If extraction from a compressed archive fails because the corresponding +compression program is not installed and the following two conditions +are met, tar retries extraction using an alternative decompressor: + + 1. Another compression program supported by tar is able to handle this + compression format. + 2. The compression program was not explicitly requested in the command + line by the use of such options as -z, -j, etc. + +For example, if 'compress' is not available, tar will try 'gzip'. + + +version 1.24 - Sergey Poznyakoff, 2010-10-24 + +* The --full-time option. + +New command line option '--full-time' instructs tar to output file +time stamps to the full resolution. + +* Bugfixes. + +** More reliable directory traversal when creating archives + +Tar now checks for inconsistencies caused when a file system is +modified while tar is creating an archive. In the new approach, tar +maintains a cache of file descriptors to directories, so it uses more +file descriptors than before, but it adjusts to system limits on +the number of file descriptors. Tar also takes more care when +a file system is modified while tar is extracting from an archive. + +The new checks are implemented via the openat and related calls +standardized by POSIX.1-2008. On an older system where these calls do +not exist or do not return useful results, tar emulates the calls at +some cost in efficiency and reliability. + +** Symbolic link attributes + +When extracting symbolic links, tar now restores attributes such as +last-modified time and link permissions, if the operating system +supports this. For example, recent versions of the Linux kernel +support setting times on symlinks, and some BSD kernels also support +symlink permissions. + +** --dereference consistency + +The --dereference (-h) option now applies to files that are copied +into or out of archives, independently of other options. For example, +if F is a symbolic link and archive.tar contains a regular-file member +also named F, "tar --overwrite -x -f archive.tar F" now overwrites F +itself, rather than the file that F points to. (To overwrite the file +that F points to, add the --dereference (-h) option.) Formerly, +--dereference was intended to apply only when using the -c option, but +the implementation was not consistent. + +Also, the --dereference option no longer affects accesses to other +files, such as archives and time stamp files. Symbolic links to these +files are always followed. Previously, the links were usually but not +always followed. + +** Spurious error diagnostics on broken pipe. + +When receiving SIGPIPE, tar would exit with error status and +"write error" diagnostics. In particular, this occurred if +invoked as in the example below: + + tar tf archive.tar | head -n 1 + +** --remove-files + +'tar --remove-files' failed to remove a directory which contained +symlinks to another files within that directory. + +** --test-label behavior + +In case of a mismatch, 'tar --test-label LABEL' exits with code 1, +not 2 as it did in previous versions. + +The '--verbose' option used with '--test-label' provides additional +diagnostics. + +Several volume labels may be specified in a command line, e.g.: + + tar --test-label -f archive 'My volume' 'New volume' 'Test volume' + +In this case, tar exits with code 0 if any one of the arguments +matches the actual volume label. + +** --label used with --update + +The '--label' option can be used with '--update' to prevent accidental +update of an archive: + + tar -rf archive --label 'My volume' . + +This did not work in previous versions, in spite of what the docs said. + +** --record-size and --tape-length (-L) options + +Usual size suffixes are allowed for these options. For example, +-L10k stands for a 10 kilobyte tape length. + +** Fix dead loop on extracting existing symlinks with the -k option. + + +version 1.23 - Sergey Poznyakoff, 2010-03-10 + +* Record size autodetection + +When listing or extracting archives, the actual record size is +reported only if the archive is read from a device (as opposed +to regular files and pipes). + +* Seekable archives + +When a read-only operation (e.g. --list or --extract) is requested +on a regular file, tar attemtps to speed up accesses by using lseek. + +* New command line option '--warning' + +The '--warning' command line option allows to suppress or enable +particular warning messages during 'tar' run. It takes a single +argument (a 'keyword'), identifying the class of warning messages +to affect. If the argument is prefixed with 'no-', such warning +messages are suppressed. For example, + + tar --warning=no-alone-zero-block -x -f archive + +suppresses the output of "A lone zero block" diagnostics, which is +normally issued if 'archive' ends with a single block of zeros. + +See Tar Manual, section 3.9 "Controlling Warning Messages", for a +detailed discussion. + +* New command line option '--level' + +The '--level=N' option sets the incremental dump level N. It +is valid when used in conjunction with the -c and --listed-incremental +options. So far the only meaningful value for N is 0. The +'--level=0' option forces creating the level 0 dump, by truncating +the snapshot file if it exists. + +* Files removed during incremental dumps + +If a file or directory is removed while incremental dump is +in progress, tar exact actions depend on whether this file +was explicitly listed in the command line, or was found +during file system scan. + +If the file was explicitly listed in the command line, tar +issues error message and exits with the code 2, meaning +fatal error. + +Otherwise, if the file was found during the file system scan, +tar issues a warning, saying "File removed before we read it", +and sets exit code to 1, which means "some files differ". +If the --warning=no-file-removed option is given, no warning +is issued and exit code remains 0. + +* Modification times of PAX extended headers. + +Modification times in ustar header blocks of extended headers +are set to mtimes of the corresponding archive members. This +can be overridden by the + + --pax-option='exthdr.mtime=STRING' + +command line option. The STRING is either number of seconds since +the Epoch or a "Time reference" (see below). + +Modification times in ustar header blocks of global extended +headers are set to the time when tar was invoked. + +This can be overridden by the + + --pax-option='globexthdr.mtime=STRING' + +command line option. The STRING is either number of seconds since +the Epoch or a "Time reference" (see below). + +* Time references in --pax-option argument. + +Any value from the --pax-option argument that is enclosed in a pair +of curly braces represents a time reference. The string between the +braces is understood either as a textual time representation, as described in +chapter 7, "Date input formats", of the Tar manual, or as a name of +an existing file, starting with '/' or '.'. In the latter +case, it is replaced with the modification time of that file. + +* Environment of --to-command script. + +The environment passed to the --to-command script is extended with +the following variables: + + TAR_VERSION GNU tar version number + TAR_ARCHIVE The name of the archive + TAR_VOLUME Ordinal number of the volume + TAR_FORMAT Format of the archive + TAR_BLOCKING_FACTOR Current blocking factor + +* Bugfixes +** Fix handling of hard link targets by -c --transform. +** Fix hard links recognition with -c --remove-files. +** Fix restoring files from backup (debian bug #508199). +** Correctly restore modes and permissions on existing directories. +** The --remove-files option removes files only if they were +succesfully stored in the archive. +** Fix storing and listing of the volume labels in POSIX format. +** Improve algorithm for splitting long file names (ustar +format). +** Fix possible memory overflow in the rmt client code (CVE-2010-0624). + + +version 1.22 - Sergey Poznyakoff, 2009-03-05 + +* Support for xz compression + +Tar uses xz for compression if one of the following conditions is met: + + 1. The option --xz or -J (see below) is used. + 2. The xz binary is set as compressor using --use-compress-program option. + 3. The file name of the archive being created ends in '.xz' and + auto-compress option (-a) is used. + +Xz is used for decompression if one of the following conditions is met: + + 1. The option --xz or -J is used. + 2. The xz binary is set as compressor using --use-compress-program option. + 3. The file is recognized as xz compressed stream data. + +* Short option -J reassigned as a short equivalent of --xz + +* New option -I + +The -I option is assigned as a short equivalent for +--use-compress-program. + +* The --no-recursive option works in incremental mode. + + +version 1.21 - Sergey Poznyakoff, 2008-12-27 + +* New short option -J + +A shortcut for --lzma. + +* New option --lzop + +* New option --no-auto-compress + +Cancels the effect of previous --auto-compress (-a) option. + +* New option --no-null + +Cancels the effect of previous --null option. + +* Compressed format recognition + +If tar is unable to determine archive compression format, it falls +back to using archive suffix to determine it. + +* VCS support. + +Using --exclude-vcs handles also files used internally by Bazaar, +Mercurial and Darcs. + +* Transformation scope flags + +Name transformation expressions understand additional flags that +control type of archive members affected by them. The flags are: + + - r + Apply transformation to regular archive members. + + - s + Apply transformation to symbolic link targets. + + - h + Apply transformation to hard link targets. + +Corresponding upper-case letters negate the meaning, so that +'H' means "do not apply transformation to hard link targets". + +The scope flags are listed in the third part of an 's' expression, +e.g.: + + tar --transform 's|^|/usr/local/|S' + +Default is 'rsh', which means that transformations are applied to +both regular archive members and to the targets of symbolic and hard +links. If several transform expressions are used, the default flags +can be changed using 'flags=' statement before the expressions, e.g.: + + tar --transform 'flags=S;s|^|/usr/local/|S' + +* Bugfixes + +** The --null option disabled handling of tar options in list files. This +is fixed. +** Fixed record size autodetection. If the detected record size differs from +the expected value (either default one, or the one set from the +command line), tar always prints a warning if verbosity level is set +to 1 or greater, i.e. if either -t or -v option is given. + + + +version 1.20 - Sergey Poznyakoff, 2008-04-14 + +* New option --auto-compress (-a) + +With --create, selects compression algorithm basing on the suffix +of the archive file name. + +* New option --lzma + +Selects LZMA compression algorithm + +* New option --hard-dereference + +During archive creation, dereferences hard links and stores the files +they refer to, instead of creating usual hard link members (type '1'). + +* New option --checkpoint-action + +This action allows to specify an action to be executed upon hitting a +checkpoint. Recognized actions are: dot, echo (the default), +echo=string, ttyout=string, exec=cmdline, and sleep=value. Any number +of '--checkpoint-action' options can be specified, the actions will be +executed in order of their appearance in the command line. See +chapter 3.8 "Checkpoints" for a complete description. + +* New options --no-check-device, --check-device. + +The '--no-check-device' option disables comparing device numbers during +preparatory stage of an incremental dump. This allows to avoid +creating full dumps if the device numbers change (e.g. when using an +LVM snapshot). + +The '--check-device' option enables comparing device numbers. This is +the default. This option is provided to undo the effect of the previous +'--no-check-device' option, e.g. if it was set in TAR_OPTIONS +environment variable. + +* The --transform option. + +Any number of '--transform' options can be given in the command line. +The specified transformations will be applied in turn. + +The argument to '--transform' option can be a list of replace +expressions, separated by a semicolon (as in 'sed'). + +Filename transformations are applied to symbolic link targets +during both creation and extraction. Tar 1.19 used them only +during extraction. + +For a detailed description, see chapter 6.7 "Modifying File and Member +Names". + +* Info (end-of-volume) scripts + +The value of the blocking factor is made available to info and +checkpoint scripts via environment variable TAR_BLOCKING_FACTOR. + +* Incremental archives + +Improved (sped up) extracting from incremental archives. + +* Bugfixes. +** Fix bug introduced in version 1.19: tar refused to update non-existing +archives. + + +version 1.19 - Sergey Poznyakoff, 2007-10-10 + +* New option --exclude-vcs + +Excludes directories and files, created by several widely used version +control systems, e.g. "CVS/", ".svn/", etc. + +* --exclude-tag and --exclude-cache options + +The following options now work with incremental archives as well: + + --exclude-caches + --exclude-caches-all + --exclude-tag + --exclude-tag-all + --exclude-tag-under + +* Fix handling of renamed files in listed incremental archives. + +Previous versions always stored absolute file names in rename +records, even if -P was not used. This is fixed: rename records +contain file names processed in accordance with the command line +settings. + +* Fix --version output. + +* Recognition of broken archives. + +When supplied an archive smaller than 512 bytes in reading mode (-x, +-t), the previous version of tar silently ignored it, exiting with +code 0. It is fixed. Tar now issues the following diagnostic message: +'This does not look like a tar archive', and exits with code 2. + +* Fix double-dot recognition in archive member names in case of duplicate '/.'. + +* Fix file padding in case of truncation of the input file to zero size. + + +version 1.18 - Sergey Poznyakoff, 2007-06-29 + +* Licensed under the GPLv3 + +* Fixed several bugs in the testsuite + + +version 1.17 - Sergey Poznyakoff, 2007-06-08 + +* Fix archivation of sparse files in posix mode. Previous versions padded + sparse members with spurious zero blocks. + +* Fix operation of --verify --listed-incremental. Version 1.16.1 produced + a full dump when both options were given. + +* Fix --occurrence. In previous versions it continued scanning the archive + even though all requested members has already been extracted. + +* Scope of --transform and --strip-components options. + +In addition to affecting regular archive members, the --transform +option affects hard and soft link targets and the --strip-components +option affects hard link targets as well. + +* End-of-volume script can send the new volume name to tar by writing + it to the file descriptor stored in the environment variable TAR_FD. + + +version 1.16.1 - Sergey Poznyakoff, 2006-12-09 + +* New option --exclude-tag allows to specify "exclusion tag files", i.e. + files whose presence in a directory means that the directory should not + be archived. + +* The --exclude-cache option excludes directories that contain the + CACHEDIR.TAG file from being archived. Previous versions excluded + directory contents only, while the directories themselves were + still added to the archive. + +* Support for reading ustar type 'N' header logical records has been removed. + This GNU extension was generated only by very old versions of GNU 'tar'. + Unfortunately its implementation had security holes; see + <http://archives.neohapsis.com/archives/fulldisclosure/2006-11/0344.html>. + We don't expect that any tar archives in practical use have type 'N' + records, but if you have one and you trust its contents, you can + decode it with GNU tar 1.16 or earlier. + +* Race conditions have been fixed that in some cases briefly allowed + files extracted by 'tar -x --same-owner' (or plain 'tar -x', when + running as root) to be accessed by users that they shouldn't have been. + + +version 1.16 - Sergey Poznyakoff, 2006-10-21 + +* After creating an archive, tar exits with code 1 if some files were +changed while being read. Previous versions exited with code 2 (fatal +error), and only if some files were truncated while being archived. + +* New option --mtime allows to set modification times for all archive +members during creation. + +* Bug fixes +** Avoid running off file descriptors when using multiple -C options. +** tar --index-file=FILE --file=- sent the archive to FILE, and +the listing to stderr. + + +version 1.15.91 - Sergey Poznyakoff, 2006-06-16 + +* Incompatible changes + +** Globbing + +Previous versions of GNU tar assumed shell-style globbing when +extracting from or listing an archive. For example: + + tar xf foo.tar '*.c' + +would extract all files whose names end in '.c'. This behavior +was not documented and was incompatible with traditional tar +implementations. Therefore, starting from this version, GNU tar +no longer uses globbing by default. For example, the above invocation +is now interpreted as a request to extract from the archive the file +named '*.c'. + +To treat member names as globbing patterns, use --wildcards option. +If you wish tar to mimic the behavior of versions up to 1.15.90, +add --wildcards to the value of the environment variable TAR_OPTIONS. + +The exact way in which tar interprets member names is controlled by the +following command line options: + + --wildcards use wildcards + --anchored patterns match file name start + --ignore-case ignore case + --wildcards-match-slash wildcards match '/' + +Each of these options has a '--no-' counterpart that disables its +effect (e.g. --no-wildcards). + +These options affect both the interpretation of member names from +command line and that of the exclusion patterns (given with --exclude +and --exclude-from options). The defaults are: + + 1. For member names: --no-wildcards --anchored + 2. For exclusion patterns: --wildcards --no-anchored --wildcards-match-slash + +The options can appear multiple times in the command line, thereby +changing the way command line arguments are interpreted. For example, +to use case-insensitive matching in exclude patterns and to revert to +case-sensitive matching for the rest of command line, one could write: + + tar xf foo.tar --ignore-case --exclude-from=FILE --no-ignore-case file.name + +** Short option -l is now an alias of --check-links option, which complies +with UNIX98. This ends the transition period started with version 1.14. + +* New features + +** New option --transform allows to transform file names before storing them +in the archive or member names before extracting. The option takes a +sed replace expression as its argument. For example, + + tar cf foo.tar --transform 's,^,prefix/,' + +will add 'prefix/' to all file names stored in foo.tar. + +** --strip-components option works when deleting and comparing. In previous +versions it worked only with --extract. + +** New option --show-transformed-names enables display of transformed file +or archive. It generalizes --show-stored-names option, introduced in +1.15.90. In particular, when creating an archive in verbose mode, it lists +member names as stored in the archive, i.e., with any eventual prefixes +removed and file name transformations applied. The option is useful, +for example, while comparing 'tar cv' and 'tar tv' outputs. + +** New incremental snapshot file format keeps information about file names +as well as that about directories. + +** The --checkpoint option takes an optional argument specifying the number +of records between the two successive checkpoints. Optional dot +starting the argument intructs tar to print dots instead of textual +checkpoints. + +** The --totals option can be used with any tar operation (previous versions +understood it only with --create). If an argument to this option is +given, it specifies the signal upon delivery of which the statistics +is to be printed. Both forms of this option (with and without +argument) can be given to in a single invocation of tar. + +* Bug fixes +** Detect attempts to update compressed archives. + + +version 1.15.90 - Sergey Poznyakoff, 2006-02-19 + +* New features + +** Any number of -T (--files-from) options may be used in the command line. +The file specified with -T may include any valid 'tar' options, +including another -T option. +Compatibility note: older versions of tar would only recognize -C +as an option name within the file list file. Now any file whose name +starts with - is handled as an option. To insert file names starting with +dash, use the --add-file option. + +** List files containing null-separated file names are detected and processed +automatically. It is no longer necessary to give the --null option. + +** New option --no-unquote disables the unquoting of input file names. +This is useful for processing output from 'find dir -print0'. +An orthogonal option --unquote is provided as well. + +** New option --test-label tests the archive volume label. +If an argument is specified, the label is compared against its value. +Tar exits with code 0 if the two strings match, and with code 2 if +they do not. + +If no argument is given, the --verbose option is implied. In this case, +tar prints the label name if present and exits with code 0. + +** New option --show-stored-names. When creating an archive in verbose mode, +it lists member names as stored in the archive, i.e., with any eventual +prefixes removed. The option is useful, for example, while comparing +'tar cv' and 'tar tv' outputs. + +** New option --to-command pipes the contents of archive members to the +specified command. + +** New option --atime-preserve=system, which uses the O_NOATIME feature +of recent Linux kernels to avoid some problems when preserving file +access times. + +** New option --delay-directory-restore delays restoring modification times +and permissions of extracted directories until the end of extraction. +This is necessary for restoring from archives with unusual member +ordering (in particular, those created with --no-recursion option). +This option is implied when restoring from incremental archives. + +** New option --restrict prohibits use of some potentially harmful tar +options. Currently it disables '!' escape in multi-volume name menu. + +** New options --quoting-style and --quote-chars control the way tar +quotes member names on output. The --quoting-style takes an argument +specifying the quoting style to use (literal, shell, shell-always, +c, escape, locale, clocale). The argument to --quote-chars is a string +specifying characters to quote, even if the selected quoting style +would not quote them otherwise. The option --no-quote-chars is +provided to disable quoting certain characters. + +** The end-of-volume script (introduced with --info-script option) can +get current archive name from the environment variable TAR_ARCHIVE and +the volume number from the variable TAR_VOLUME. It can alter the +archive name by writing new name to the file descriptor 3. + +** Better support for full-resolution time stamps. Tar cannot restore +time stamps to full nanosecond resolution, though, until the kernel +guys get their act together and give us a system call to set file time +stamps to nanosecond resolution. + +** The -v option now prints time stamps only to 1-minute resolution, +not full resolution, to avoid using up too many output columns. +Nanosecond resolution is now supported, but that would be too much. + +* Bug fixes + +** Allow non-option arguments to be interspersed with options. +** When extracting or listing archives in old GNU format, tar +used to read an extra block of data after a long name header +if length of the member name was divisible by block size (512). +Consequently, the file pointer was set off and the next member +was not processed correctly. +** Previous version created invalid archives when files shrink +during reading. +** Compare mode (tar d) hung when trying to compare file contents. +** Previous versions in certain cases failed to restore directory +modification times. +** When creating an archive, do not attempt to store files whose +meta-data cannot be stored in the header due to format limitations +(for ustar and v7 formats). +** The --version option now also outputs information about copyright, +license, and credits. This reverts to the behavior of tar 1.14 and +earlier, and conforms to the GNU coding standards. The --license (-L) +option introduced in tar 1.15 has been removed, since it's no longer +needed. + + +version 1.15.1 - Sergey Poznyakoff, 2004-12-21 + +This version fixes a bug introduced in 1.15 which caused +tar to refuse to extract files from standard input. + + +version 1.15 - Sergey Poznyakoff, 2004-12-20 + +* Compressed archives are recognised automatically, it is no longer +necessary to specify -Z, -z, or -j options to read them. Thus, you can +now run 'tar tf archive.tar.gz'. + +* When restoring incremental dumps, --one-file-system option +prevents directory hierarchies residing on different devices +from being purged. + +With the previous versions of tar it was dangerous to create +incremental dumps with --one-file-system option, since they +would recursively remove mount points when restoring from the +back up. This change fixes the bug. + +* Renamed --strip-path to --strip-components for consistency with +the GNU convention. + +* Skipping archive members is sped up if the archive media supports +seeks. + +* Restore script starts restoring only if it is given --all (-a) option, +or some patterns. This is to prevent accidental restores. + +* 'tar --verify' prints a warning if during archive creation some of +the file names had their prefixes stripped off. + +* New option --exclude-caches instructs tar to exclude cache directories +automatically on archive creation. Cache directories are those +containing a standardized tag file, as specified at: + + http://www.brynosaurus.com/cachedir/spec.html + +* New configure option --with-rmt allows to specify full path name to +the 'rmt' utility. This supersedes DEFAULT_RMT_COMMAND variable +introduced in version 1.14 + +* New configure variable DEFAULT_RMT_DIR allows to specify the directory +where to install 'rmt' utility. This is necessary since modifying +--libexecdir as was suggested for version 1.14 produced a side effect: it +also modified installation prefix for backup scripts (if +--enable-backup-scripts was given). + +* Bug fixes: +** Fixed flow in recognizing files to be included in incremental dumps. +** Correctly recognize sparse archive members when used with -T option. +** GNU multivolume headers cannot store filenames longer than 100 characters. +Do not allow multivolume archives to begin with such filenames. +** If a member with link count > 2 was stored in the archive twice, +previous versions of tar were not able to extract it, since they +were trying to link the file to itself, which always failed and +lead to removing the already extracted copy. Preserve the first +extracted copy in such cases. +** Restore script was passing improper argument to tar --listed option (which +didn't affect the functionality, but was logically incorrect). +** Fixed verification of created archives. +** Fixed unquoting of file names containing backslash escapes (previous +versions failed to recognize \a and \v). +** When attempting to delete a non-existing member from the archive, previous +versions of tar used to overwrite last archive block with zeroes. + + +version 1.14 - Sergey Poznyakoff, 2004-05-11 + +* Added support for POSIX.1-2001 and ustar archive formats. +* New option --format allows to select the output archive format +* The default output format can be selected at configuration time + by presetting the environment variable DEFAULT_ARCHIVE_FORMAT. + Allowed values are GNU, V7, OLDGNU and POSIX. +* New option --strip-path allows to cut off a given number of + path elements from the name of the file being extracted. + +* New options --index-file, --no-overwrite-dir. The --overwrite-dir + option is now the default; use --no-overwrite-dir if you prefer + the previous default behavior. + +* The semantics of -o option is changed. When extracting, it + does the same as --no-same-owner GNU tar option. This is compatible + with UNIX98 tar. Otherwise, its effect is the same as that of + --old-archive option. This latter is deprecated and will be removed + in future. + +* New option --check-links prints a message if not all links are dumped + for a file being archived. This corresponds to the UNIX98 -l option. + The current semantics of the -l option is retained for compatibility + with previous releases, however such usage is strongly deprecated as + the option will change to its UNIX98 semantics in the future releases. + +* New option --occurrence[=N] can be used in conjunction with one of + the subcommands --delete, --diff, --extract or --list when a list of + files is given either on the command line or via -T option. This + option instructs tar to process only the Nth occurrence of each named + file. N defaults to 1, so 'tar -x -f archive --occurrence filename' + extracts the first occurrence of 'filename' from 'archive' + and terminates without scanning to the end of the archive. + +* New option --pax-option allows to control the handling of POSIX + keywords in 'pax' extended headers. It is equivalent to 'pax' + -o option. + +* --incremental and --listed-incremental options work correctly on + individual files, as well as on directories. + +* New scripts: backup (replaces old level-0 and level-1) and restore. +The scripts are compiled and installed if --enable-backup-scripts +option is given to configure. + +* By default tar searches "rmt" utility in "$prefix/libexec/rmt", +which is consistent with the location where the version of "rmt" +included in the package is installed. Previous versions of tar +used "/etc/rmt". To install "rmt" to its traditional location, +run configure with option --libexecdir=/etc. Otherwise, if you +already have rmt installed and wish to use it, instead of the +shipped in version, set the variable DEFAULT_RMT_COMMAND to +the full path name of the utility, e.g., ./configure +DEFAULT_RMT_COMMAND=/etc/rmt. + +Notice also that the full path name of the "rmt" utility to +use can be set at runtime, by giving option --rmt-command to +tar. + +* Removed obsolete command line options: +** --absolute-paths superseded by --absolute-names +** --block-compress is not needed any longer +** --block-size superseded by --blocking-factor +** --modification-time superseded by --touch +** --read-full-blocks superseded by --read-full-records +** --record-number superseded by --block-number +** --version-control superseded by --backup + +* New message translations fi (Finnish), gl (Galician), hr (Croatian), + hu (Hungarian), ms (Malaysian), nb (Norwegian), ro (Romanian), sk + (Slovak), zh_CN (Chinese simplified), zh_TW (Chinese traditional). + The code 'no' for Norwegian (Bokmål) has been withdrawn; use 'nb' instead. + +* Bug fixes. + + +version 1.13.25 - Paul Eggert, 2001-09-26 + +* Bug fixes. + + +version 1.13.24 - Paul Eggert, 2001-09-22 + +* New option --overwrite-dir. +* Fixes for buffer overrun, porting, and copyright notice problems. +* The message translations for Korean are available again. + + +version 1.13.23 - Paul Eggert, 2001-09-13 + +* Bug, porting, and copyright notice fixes. + + +version 1.13.22 - Paul Eggert, 2001-08-29 + +* Bug fixes. + + +version 1.13.21 - Paul Eggert, 2001-08-28 + +* Porting and copyright notice fixes. + + +version 1.13.20 - Paul Eggert, 2001-08-27 + +* Some bugs were fixed: + - security problems + - hard links to symbolic links + +* New option --recursion (the default) that is the inverse of --no-recursion. + +* New options --anchored, --ignore-case, --wildcards, + --wildcards-match-slash, and their negations (e.g., --no-anchored). + Along with --recursion and --no-recursion, these options control how + exclude patterns are interpreted. + +* The default interpretation of exclude patterns is now --no-anchored + --no-ignore-case --recursion --wildcards --wildcards-match-slash. + This is a quiet change to the semantics of --exclude. The previous + semantics were a failed attempt at backward compatibility but it + became clear that the semantics were puzzling and did not satisfy + everybody. Rather than continue to try to revive that dead horse we + thought it better to substitute cleaner semantics, with options so + that you can change the behavior more to your liking. + +* New message translations for Indonesian and Turkish. + The translation for Korean has been withdrawn due to encoding errors. + It will be reissued once those are fixed. + + +version 1.13.19 - Paul Eggert, 2001-01-13 + +* The -I option has been withdrawn, as it was buggy and confusing. + Eventually it is planned to be reintroduced, with the same meaning as -T. + +* With an option like -N DATE, if DATE starts with "/" or ".", it is taken + to be a file name; the last-modified time of that file is used as the date. + + +version 1.13.18 - Paul Eggert, 2000-10-29 + +* Some security problems have been fixed. 'tar -x' now modifies only + files under the working directory, unless you also specify an unsafe + option like --absolute-names or --overwrite. + +* The short name of the --bzip option has been changed to -j, + and -I is now an alias for -T, for compatibility with Solaris tar. + +* The manual is now distributed under the GNU Free Documentation License. + +* The new environment variable TAR_OPTIONS holds default command-line options. + +* The --no-recursion option now affects extraction too. + +* The wording in some diagnostics has been changed slightly. + +* Snapshot files now record whether each file was accessed via NFS. + The new file format is upward- and downward-compatible with the old. + +* New language supported: da. + +* Compilation by traditional (K&R) C compilers is no longer supported. + If you still use such a compiler, please use GCC instead. + +* This version of tar works best with GNU gzip test version 1.3 or later. + Please see <ftp://alpha.gnu.org/gnu/gzip/>. + +* 'tar --delete -f -' now works again. + + +version 1.13.17 - Paul Eggert, 2000-01-07. + +* 'tar --delete -f -' is no longer allowed; it was too buggy. +* Diagnostic messages have been made more regular and consistent. + + +version 1.13.16 - Paul Eggert, 1999-12-13. + +* By default, tar now refuses to overwrite an existing file when + extracting files from an archive; instead, it removes the file + before extracting it. If the existing file is a symbolic link, the + link is removed and not the pointed-to file. There is one + exception: existing nonempty directories are not removed, nor are + their ownerships or permissions extracted. This fixes some + longstanding security problems. + + The new --overwrite option enables the old default behavior. + + For regular files, tar implements this change by using the O_EXCL + option of 'open' to ensure that it creates the file; if this fails, it + removes the file and tries again. This is similar to the behavior of + the --unlink-first option, but it is faster in the common case of + extracting a new directory. + +* By default, tar now ignores file names containing a component of '..' + when extracting, and warns about such file names when creating an archive. + To enable the old behavior, use the -P or --absolute-names option. + +* Tar now handles file names with multibyte encodings (e.g., UTF-8, Shift-JIS) + correctly. It relies on the mbrtowc function to handle multibyte characters. + +* The file generated by -g or --listed-incremental now uses a format + that is independent of locale, so that users need not worry about + locale when restoring a backup. This is needed for proper support + of multibyte characters. Old-format files can still be read, and + older versions of GNU tar can read new-format files, unless member + names have multibyte chars. + +* Many diagnostics have been changed slightly, so that file names are + now output unambiguously. File names in diagnostics now are either + `quoted like this' (in the default C locale) or are followed by + colon, newline, or space, depending on context. Unprintable + characters are escaped with a C-like backslash conventions. + Terminating characters (e.g., close-quote, colon, newline) + are also escaped as needed. + +* tar now ignores socket files when creating an archive. + Previously tar archived sockets as fifos, which caused problems. + + +version 1.13.15 - Paul Eggert, 1999-12-03. + +* If a file's ctime changes when being archived, report an error. + Previously tar looked at mtime, which missed some errors. + + +version 1.13.14 - Paul Eggert, 1999-11-07. + +* New translations ja, pt_BR. +* New options --help and --version for rmt. +* Ignore Solaris door files when creating an archive. + + +version 1.13.13 - Paul Eggert, 1999-10-11. + +* Invalid headers in tar files now elicit errors, not just warnings. +* 'tar --version' output conforms to the latest GNU coding standards. +* If you specify an invalid date, 'tar' now substitutes (time_t) -1. +* 'configure --with-dmalloc' is no longer available. + + +version 1.13.12 - Paul Eggert, 1999-09-24. + +* 'tar' now supports hard links to symbolic links. + +* New options --no-same-owner, --no-same-permissions. + +* --total now also outputs a human-readable size, and a throughput value. + +* 'tar' now uses two's-complement base-256 when outputting header + values that are out of the range of the standard unsigned base-8 + format. This affects archive members with negative or huge time + stamps or uids, and archive members 8 GB or larger. The new tar + archives cannot be read by traditional tar, or by older versions of + GNU tar. Use the --old-archive option to revert to the old + behavior, which uses unportable representations for negative values, + and which rejects large files. + +* On 32-bit hosts, 'tar' now assumes that an incoming time stamp T in + the range 2**31 <= T < 2**32 represents the negative time (T - + 2**32). This behavior is nonstandard and is not portable to 64-bit + time_t hosts, so 'tar' issues a warning. + +* 'tar' no longer gives up extracting immediately upon discovering + that an archive contains garbage at the end. It attempts to extract + as many files as possible from the good data before the garbage. + +* A read error now causes a nonzero exit status, not just a warning. + +* Some diagnostics have been reworded for consistency. + + +version 1.13.11 - Paul Eggert, 1999-08-23. + +* The short name of the --bzip option has been changed to -I, + for compatibility with paxutils. + +* -T /dev/null now matches nothing; previously, it matched anything + if no explicit operands were given. + +* The '--' option now works the same as with other GNU utilities; + it causes later operands to be interpreted as file names, not options, + even if they begin with '-'. + +* For the --newer and --after-date options, the table of time zone + abbreviations like 'EST' has been updated to match current practice. + Also, local time abbreviations are now recognized, even if they are + not in tar's hardwired table. Remember, though, that you should use + numeric UTC offsets like '-0500' instead of abbreviations like + 'EST', as abbreviations are not standardized and are ambiguous. + + +version 1.13.10 - Paul Eggert, 1999-08-20. + +* 'tar' now uses signed base-64 when outputting header values that are + out of the range of the standard unsigned base-8 format. [This + change was superseded in 1.13.12, described above.] + + +version 1.13.9 - Paul Eggert, 1999-08-18. + +* 'tar' now writes two zero blocks at end-of-archive instead of just one. + POSIX.1 requires this, and some other 'tar' implementations check for it. + +* 'tar' no longer silently accepts a block containing nonzero checksum bytes + as a zero block. + +* 'tar' now reads buggy tar files that have a null byte at the start of a + numeric header field. + + +version 1.13.8 - Paul Eggert, 1999-08-16. + +* For compatibility with traditional 'tar', intermediate directories + created automatically by root are no longer given the uid and gid of + the original file or directory. + + +version 1.13.7 - Paul Eggert, 1999-08-14. + +* --listed-incremental and --newer are now incompatible options. + +* When creating an archive, leading './' is no longer stripped, + to match traditional tar's behavior (and simplify the documentation). + +* --diff without --absolute-names no longer falls back on absolute names. + + +version 1.13.6 - Paul Eggert, 1999-08-11. + +* An --exclude pattern containing / now excludes a file only if it matches an + initial prefix of the file name; a pattern without / continues to + exclude a file if it matches any file name component. + +* The protocol for talking to rmt has been extended slightly. + Open flags are now communicated in symbolic format as well as numeric. + The symbolic format (e.g., "O_WRONLY|O_CREAT|O_TRUNC") is for portability + when rmt is operating on a different operating system from tar. + The numeric format is retained, and rmt uses it if symbolic format is absent, + for backward compatibility with older versions of tar and rmt. + +* When writing GNU tar format headers, tar now uses signed base-64 + for values that cannot be represented in unsigned octal. + This supports larger files (2**66 - 1 bytes instead of 2**33 - 1 bytes), + larger uids, negative time stamps, etc. + +* When extracting files with unknown ownership, tar now looks up the + uid and gid "nobody" on hosts whose headers do not define UID_NOBODY + and GID_NOBODY, and falls back on uid/gid -2 if there is no "nobody". + +* tar -t --numeric-owner now prints numeric uids and gids, not symbolic. + +* New option -y or --bzip2 for bzip2 compression, by popular request. + + +version 1.13.5 - Paul Eggert, 1999-07-20. + +* Do the delayed updates of file metadata even after a fatal error. + + +version 1.13.4 - Paul Eggert, 1999-07-20. + +* Do not chmod unless we are root or the -p option was given; + this matches historical practice. + + +version 1.13.3 - Paul Eggert, 1999-07-16. + +* A path name is excluded if any of its file name components matches an + excluded pattern, even if the path name was specified on the command line. + Also see 1.13.6 for later changes in this area. + + +version 1.13.2 - Paul Eggert, 1999-07-14. + +* Bug reporting address changed to <bug-tar@gnu.org>. + + +version 1.13.1 - Paul Eggert, 1999-07-12. + +* Bug fixes only. + +version 1.13 - Paul Eggert, 1999-07-08. + +* Support for large files, e.g., files larger than 2 GB on many 32-bit hosts. + Also, support for larger uids, device ids, etc. +* Many bug fixes and porting fixes. +* This release is only for fixes. A more ambitious test release, + with new features, is available as part of the paxutils. Please see: + ftp://alpha.gnu.org/gnu/paxutils/ + The fixes in this release are intended to be merged with paxutils + at some point, but they haven't been merged yet. +* An interim GNU tar alpha had new --bzip2 and --ending-file options, + but they have been removed to maintain compatibility with paxutils. + Please try --use=bzip2 instead of --bzip2. + +Version 1.12 - François Pinard, 1997-04. + +Sensitive matters +* Use shell globbing patterns for --label, instead of regular expressions. +* Do not quote anymore internally over the quoting done by the shell. + +Output for humans +* Offer internationalization capabilities of most recent GNU gettext. +* Messages available in many more languages, thanks to all translators! +* Usage of ISO 8601 dates in listings, instead of local American dates. +* More normalization and cleanup in error messages. + +Creation +* For helping using tar with find, offer a --no-recursion option. +* Implement --numeric-owner for ignoring symbolic names at create time. +* New --owner, --group --mode options, still preliminary. +* Recognize creating an archive on /dev/null, so Amanda works faster. +* Object to the creation of an empty archive (like in 'tar cf FILE'). +* Barely start implementing --posix and POSIXLY_CORRECT. + +Extraction +* Make a better job at restoring file and directory attributes. +* Automatically attempt deleting existing files when in the way. +* Option --unlink-first (-U) removes most files prior to extraction. +* Option --recursive-unlink removes non-empty directories when in the way. +* Option --numeric-owner ignores owner/group names, it uses UID/GID instead. +* Use global umask when creating missing intermediate directories. +* When symlinks are not available, extract symbolic links as hard links. +* Diagnose extraction of contiguous files as regular files. +* New --backup, --suffix and --version-control options. + +Various changes +* Better support of huge archives with --tape-length and --totals. +* Rename option --read-full-blocks (-B) to --read-full-records (-B). +* Rename option --block-size (-b) to --blocking-factor (-b). +* Rename option --record-number (-R) to --block-number (-R). +* With --block-number (-R), report null blocks and end of file. +* Implement --record-size for introducing a size in bytes. +* Delete --block-compress option and rather decide it automatically. +* Rename option --modification-time to --touch. + +Many bugs are squashed, while others still run free. + +Version 1.11.8 - François Pinard, 1995-06. + +* Messages available in French, German, Portuguese and Swedish. +* The distribution provides a rudimentary Texinfo manual. +* The device defaults to stdin/stdout, unless overridden by the installer. +* Option --sparse (-S) should work on more systems. +* Option --rsh-command may select an alternative remote shell program. + +Most changes are internal, and should yield better portability. + +Version 1.11.2 - Michael Bushnell, 1993-03. + +* Changes in backup scripts: cleaned up considerably; notices error +conditions better over rsh; DUMP_REMIND_SCRIPT is now an option in +backup-specs; new file dump-remind is an example of a +DUMP_REMIND_SCRIPT. + +* Superfluous "Reading dirname" was a bug; fixed. + +* Incompatibility problems with a bug on Solaris are fixed. + +* New option --gzip (aliases are --ungzip and -z); calls gzip instead +of compress. Also, --use-compress-program lets you specify any +compress program. --compress-block is renamed --block-compress and +now requires one of the three compression options to be specified. + +* Several error messages are cleaned up. + +* Directory owners are now set properly when running as root. + +* Provide DUMP_REMIND_SCRIPT in backup-specs as a possible option +for --info-script. + +* Behave better with broken rmt servers. + +* Dump scripts no longer use --atime-preserve; this causes a nasty probem. + +* Several Makefile cleanups. + +Version 1.11.1 - Michael Bushnell, 1992-09. + +* Many bug fixes. + +Version 1.11 - Michael Bushnell, 1992-09. +Version 1.10.16 - 1992-07. +Version 1.10.15 - 1992-06. +Version 1.10.14 - 1992-05. +Version 1.10.13 - 1992-01. + +* Many bug fixes. + +* Now uses GNU standard configure, generated by Autoconf. + +* Long options now use '--'; use of '+' is deprecated and support +for it will eventually be removed. + +* New option --null causes filenames read by -T to be +null-terminated, and causes -C to be ignored. + +* New option --remove-files deletes files (but not directories) +after they are added to the archive. + +* New option --ignore-failed-read prevents read-errors from affecting +the exit status. + +* New option --checkpoint prints occasional messages as the tape +is being read or written. + +* New option --show-omitted-dirs prints the names of directories +omitted from the archive. + +* Some tape drives which use a non-standard method of indicating +end-of-tape now work correctly with multi-tape archives. + +* --volno-file: Read the volume number used in prompting the user +(but not in recording volume ID's on the archive) from a file. + +* When using --multi-volume, you can now give multiple -f arguments; +the various tape drives will get used in sequence and then wrap +around to the beginning. + +* Remote archive names no longer have to be in /dev: any file with a +':' is interpreted as remote. If new option --force-local is given, +then even archive files with a ':' are considered local. + +* New option --atime-preserve restores (if possible) atimes to +their original values after dumping the file. + +* No longer does tar confusingly dump "." when you don't tell it +what to dump. + +* When extracting directories, tar now correctly restores their +modification and access times. + +* Longnames support is redone differently--long name info directly +precedes the long-named file or link in the archive, so you no +longer have to wait for the extract to hit the end of the tape for +long names to work. + +Version 1.10 - Michael Bushnell, 1991-07. + +* Filename to -G is optional. -C works right. Names +newer and ++newer-mtime work right. + +* -g is now +incremental, -G is now +listed-incremental. + +* Sparse files now work correctly. + +* +volume is now called +label. + +* +exclude now takes a filename argument, and +exclude-from does +what +exclude used to do. + +* Exit status is now correct. + +* +totals keeps track of total I/O and prints it when tar exits. + +* When using +label with +extract, the label is now a regexp. + +* New option +tape-length (-L) does multi-volume handling like BSD +dump: you tell tar how big the tape is and it will prompt at that +point instead of waiting for a write error. + +* New backup scripts level-0 and level-1 which might be useful +to people. They use a file "backup-specs" for information, and +shouldn't need local modification. These are what we use to do +all our backups at the FSF. + +Version 1.09 - Jay Fenlason, 1990-10. +Version 1.08 - Jay Fenlason, 1990-01. +Versions 1.07 back to 1.00 by Jay Fenlason. + +* See ChangeLog for more details. + + + +Copyright 1994-2001, 2003-2010, 2013-2016 Free Software Foundation, Inc. + +This file is part of GNU tar. + +GNU tar 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. + +GNU tar 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.
