2 Please send GNU tar bug reports to <bug-tar@gnu.org>
7 * New checkpoint action: totals
9 The --checkpoint-action=totals option instructs tar to output the
10 total number of bytes transferred at each checkpoint.
12 * Extended checkpoint format specification.
14 New conversion specifiers are implemented. Some of them take
15 optional arguments, supplied in curly braces between the percent
16 sign and the specifier letter.
18 %d - output number of seconds since tar started
19 %{r,w,d}T - output I/O totals; optional arguments supply prefixes
20 to be used before number of bytes read, written and
21 deleted, correspondingly.
22 %{FMT}t - output current local time using FMT as strftime(3) format
23 If {FMT} is omitted, use %c
24 %{N}* - pad output with spaces to the Nth column, or to the
25 current screen width, if {N} is not given.
26 %c - a shortcut for "%{%Y-%m-%d %H:%M:%S}t: %ds, %{read,wrote}T%*\r"
29 version 1.27.1 - Sergey Poznyakoff, 2013-11-17
33 * Fix unquoting of file names obtained via the -T option.
35 * Fix GNU long link header timestamp (backward compatibility).
37 * Fix extracting sparse members from star archives.
40 version 1.27 - Sergey Poznyakoff, 2013-10-05
44 ** Sparse files with large data
46 When creating a PAX-format archive, tar no longer arbitrarily restricts
47 the size of the representation of a sparse file to be less than 8 GiB.
51 In the default C locale, diagnostics and output of 'tar' have been
52 adjusted to quote 'like this' (with apostrophes) instead of `like this'
53 (with an accent grave character and an apostrophe). This tracks
54 recent changes to the GNU coding standards.
56 * --owner and --group names and numbers
58 The --owner and --group options now accept operands of the form
59 NAME:NUM, so that you can specify both symbolic name and numeric ID
60 for owner and group. In these options, NAME no longer needs to be
61 present in the current host's user and group databases.
63 * The --keep-old-files and --skip-old-files options.
65 This release restores the traditional functionality of the
66 --keep-old-files. This option causes tar to avoid replacing
67 existing files while extracting and to treat such files as errors.
68 Tar will emit a prominent error message upon encountering such files
69 and will exit with code 2 when finished extracting the archive.
71 A new option --skip-old-files is introduced, which acts exactly as
72 --keep-old-files, except that it does not treat existing files as
73 errors. Instead it just silently skips them. An additional level of
74 verbosity can be obtained by using the option --warning=existing-file
75 together with this option.
77 * Support for POSIX ACLs, extended attributes and SELinux context.
79 Starting with this version tar is able to store, extract and list
80 extended file attributes, POSIX.1e ACLs and SELinux context. This is
81 controlled by the command line options --xattrs, --acls and --selinux,
82 correspondingly. Each of these options has a `--no-' counterpart
83 (e.g. --no-xattrs), which disables the corresponding feature.
84 Additionally, the options --xattrs-include and --xattrs-exclude allow
85 you to selectively control for which files to store (or extract) the
88 * Passing command line arguments to external commands.
90 Any option taking a command name as its argument now accepts a full
91 command line as well. Thus, it is now possible to pass additional
92 arguments to invoked programs. The affected options are:
94 --checkpoint-action=exec
95 -I, --use-compress-program
99 Furthermore, if any additional information is supplied to such a
100 command via environment variables, these variables can now be used in
101 the command line itself. Care should be taken to escape them, to
102 prevent from being expanded too early, for example:
104 tar -x -f a.tar --info-script='changevol $TAR_ARCHIVE $TAR_VOLUME'
106 * New configure option --enable-gcc-warnings, intended for debugging.
108 * New warning control option --warning=[no-]record-size
110 On extraction, this option controls whether to display actual record
111 size, if it differs from the default.
113 * New command line option --keep-directory-symlink
115 By default, if trying to extract a directory from the archive,
116 tar discovers that the corresponding file name already exists and is a
117 symbolic link, it first unlinks the entry, and then extracts the directory.
119 This option disables this behavior and instructs tar to follow
120 symlinks to directories when extracting from the archive.
122 It is mainly intended to provide compatibility with the Slackware
123 installation scripts.
126 version 1.26 - Sergey Poznyakoff, 2011-03-12
130 ** Fix the --verify option, which broke in version 1.24.
132 ** Fix storing long sparse file names in PAX archives.
134 ** Fix correctness of --atime-preserve=replace
136 tar --atime-preserve=replace no longer tries to restore atime of
139 ** Work around POSIX incompatibilities on FreeBSD, NetBSD and Tru64
141 ** Fix bug with --one-file-system --listed-incremental
143 When invoked with these two options, tar 1.25 would add only the
144 top-level directory to the archive, but not its contents.
147 version 1.25 - Sergey Poznyakoff, 2010-11-07
149 * Fix extraction of empty directories with the -C option in effect.
150 * Fix extraction of device nodes.
151 * Make sure name matching occurs before eventual name transformation.
153 Tar 1.24 changed the ordering of name matching and name transformation
154 so that the former saw already transformed file names. This made it
155 impossible to match file names in certain cases. It is fixed now.
157 * Fix the behavior of tar -x --overwrite on hosts lacking O_NOFOLLOW.
159 * Improve the testsuite.
161 * Alternative decompression programs.
163 If extraction from a compressed archive fails because the corresponding
164 compression program is not installed and the following two conditions
165 are met, tar retries extraction using an alternative decompressor:
167 1. Another compression program supported by tar is able to handle this
169 2. The compression program was not explicitly requested in the command
170 line by the use of such options as -z, -j, etc.
172 For example, if 'compress' is not available, tar will try 'gzip'.
175 version 1.24 - Sergey Poznyakoff, 2010-10-24
177 * The --full-time option.
179 New command line option '--full-time' instructs tar to output file
180 time stamps to the full resolution.
184 ** More reliable directory traversal when creating archives
186 Tar now checks for inconsistencies caused when a file system is
187 modified while tar is creating an archive. In the new approach, tar
188 maintains a cache of file descriptors to directories, so it uses more
189 file descriptors than before, but it adjusts to system limits on
190 the number of file descriptors. Tar also takes more care when
191 a file system is modified while tar is extracting from an archive.
193 The new checks are implemented via the openat and related calls
194 standardized by POSIX.1-2008. On an older system where these calls do
195 not exist or do not return useful results, tar emulates the calls at
196 some cost in efficiency and reliability.
198 ** Symbolic link attributes
200 When extracting symbolic links, tar now restores attributes such as
201 last-modified time and link permissions, if the operating system
202 supports this. For example, recent versions of the Linux kernel
203 support setting times on symlinks, and some BSD kernels also support
206 ** --dereference consistency
208 The --dereference (-h) option now applies to files that are copied
209 into or out of archives, independently of other options. For example,
210 if F is a symbolic link and archive.tar contains a regular-file member
211 also named F, "tar --overwrite -x -f archive.tar F" now overwrites F
212 itself, rather than the file that F points to. (To overwrite the file
213 that F points to, add the --dereference (-h) option.) Formerly,
214 --dereference was intended to apply only when using the -c option, but
215 the implementation was not consistent.
217 Also, the --dereference option no longer affects accesses to other
218 files, such as archives and time stamp files. Symbolic links to these
219 files are always followed. Previously, the links were usually but not
222 ** Spurious error diagnostics on broken pipe.
224 When receiving SIGPIPE, tar would exit with error status and
225 "write error" diagnostics. In particular, this occurred if
226 invoked as in the example below:
228 tar tf archive.tar | head -n 1
232 'tar --remove-files' failed to remove a directory which contained
233 symlinks to another files within that directory.
235 ** --test-label behavior
237 In case of a mismatch, 'tar --test-label LABEL' exits with code 1,
238 not 2 as it did in previous versions.
240 The '--verbose' option used with '--test-label' provides additional
243 Several volume labels may be specified in a command line, e.g.:
245 tar --test-label -f archive 'My volume' 'New volume' 'Test volume'
247 In this case, tar exits with code 0 if any one of the arguments
248 matches the actual volume label.
250 ** --label used with --update
252 The '--label' option can be used with '--update' to prevent accidental
253 update of an archive:
255 tar -rf archive --label 'My volume' .
257 This did not work in previous versions, in spite of what the docs said.
259 ** --record-size and --tape-length (-L) options
261 Usual size suffixes are allowed for these options. For example,
262 -L10k stands for a 10 kilobyte tape length.
264 ** Fix dead loop on extracting existing symlinks with the -k option.
267 version 1.23 - Sergey Poznyakoff, 2010-03-10
269 * Record size autodetection
271 When listing or extracting archives, the actual record size is
272 reported only if the archive is read from a device (as opposed
273 to regular files and pipes).
277 When a read-only operation (e.g. --list or --extract) is requested
278 on a regular file, tar attemtps to speed up accesses by using lseek.
280 * New command line option '--warning'
282 The '--warning' command line option allows to suppress or enable
283 particular warning messages during 'tar' run. It takes a single
284 argument (a 'keyword'), identifying the class of warning messages
285 to affect. If the argument is prefixed with 'no-', such warning
286 messages are suppressed. For example,
288 tar --warning=no-alone-zero-block -x -f archive
290 suppresses the output of "A lone zero block" diagnostics, which is
291 normally issued if 'archive' ends with a single block of zeros.
293 See Tar Manual, section 3.9 "Controlling Warning Messages", for a
296 * New command line option '--level'
298 The '--level=N' option sets the incremental dump level N. It
299 is valid when used in conjunction with the -c and --listed-incremental
300 options. So far the only meaningful value for N is 0. The
301 '--level=0' option forces creating the level 0 dump, by truncating
302 the snapshot file if it exists.
304 * Files removed during incremental dumps
306 If a file or directory is removed while incremental dump is
307 in progress, tar exact actions depend on whether this file
308 was explicitly listed in the command line, or was found
309 during file system scan.
311 If the file was explicitly listed in the command line, tar
312 issues error message and exits with the code 2, meaning
315 Otherwise, if the file was found during the file system scan,
316 tar issues a warning, saying "File removed before we read it",
317 and sets exit code to 1, which means "some files differ".
318 If the --warning=no-file-removed option is given, no warning
319 is issued and exit code remains 0.
321 * Modification times of PAX extended headers.
323 Modification times in ustar header blocks of extended headers
324 are set to mtimes of the corresponding archive members. This
325 can be overridden by the
327 --pax-opion='exthdr.mtime=STRING'
329 command line option. The STRING is either number of seconds since
330 the Epoch or a "Time reference" (see below).
332 Modification times in ustar header blocks of global extended
333 headers are set to the time when tar was invoked.
335 This can be overridden by the
337 --pax-opion='globexthdr.mtime=STRING'
339 command line option. The STRING is either number of seconds since
340 the Epoch or a "Time reference" (see below).
342 * Time references in --pax-option argument.
344 Any value from the --pax-option argument that is enclosed in a pair
345 of curly braces represents a time reference. The string between the
346 braces is understood either as a textual time representation, as described in
347 chapter 7, "Date input formats", of the Tar manual, or as a name of
348 an existing file, starting with '/' or '.'. In the latter
349 case, it is replaced with the modification time of that file.
351 * Environment of --to-command script.
353 The environment passed to the --to-command script is extended with
354 the following variables:
356 TAR_VERSION GNU tar version number
357 TAR_ARCHIVE The name of the archive
358 TAR_VOLUME Ordinal number of the volume
359 TAR_FORMAT Format of the archive
360 TAR_BLOCKING_FACTOR Current blocking factor
363 ** Fix handling of hard link targets by -c --transform.
364 ** Fix hard links recognition with -c --remove-files.
365 ** Fix restoring files from backup (debian bug #508199).
366 ** Correctly restore modes and permissions on existing directories.
367 ** The --remove-files option removes files only if they were
368 succesfully stored in the archive.
369 ** Fix storing and listing of the volume labels in POSIX format.
370 ** Improve algorithm for splitting long file names (ustar
372 ** Fix possible memory overflow in the rmt client code (CVE-2010-0624).
375 version 1.22 - Sergey Poznyakoff, 2009-03-05
377 * Support for xz compression
379 Tar uses xz for compression if one of the following conditions is met:
381 1. The option --xz or -J (see below) is used.
382 2. The xz binary is set as compressor using --use-compress-program option.
383 3. The file name of the archive being created ends in '.xz' and
384 auto-compress option (-a) is used.
386 Xz is used for decompression if one of the following conditions is met:
388 1. The option --xz or -J is used.
389 2. The xz binary is set as compressor using --use-compress-program option.
390 3. The file is recognized as xz compressed stream data.
392 * Short option -J reassigned as a short equivalent of --xz
396 The -I option is assigned as a short equivalent for
397 --use-compress-program.
399 * The --no-recursive option works in incremental mode.
402 version 1.21 - Sergey Poznyakoff, 2008-12-27
404 * New short option -J
406 A shortcut for --lzma.
410 * New option --no-auto-compress
412 Cancels the effect of previous --auto-compress (-a) option.
414 * New option --no-null
416 Cancels the effect of previous --null option.
418 * Compressed format recognition
420 If tar is unable to determine archive compression format, it falls
421 back to using archive suffix to determine it.
425 Using --exclude-vcs handles also files used internally by Bazaar,
428 * Transformation scope flags
430 Name transformation expressions understand additional flags that
431 control type of archive members affected by them. The flags are:
434 Apply transformation to regular archive members.
437 Apply transformation to symbolic link targets.
440 Apply transformation to hard link targets.
442 Corresponding upper-case letters negate the meaning, so that
443 'H' means "do not apply transformation to hard link targets".
445 The scope flags are listed in the third part of an 's' expression,
448 tar --transform 's|^|/usr/local/|S'
450 Default is 'rsh', which means that transformations are applied to
451 both regular archive members and to the targets of symbolic and hard
452 links. If several transform expressions are used, the default flags
453 can be changed using 'flags=' statement before the expressions, e.g.:
455 tar --transform 'flags=S;s|^|/usr/local/|S'
459 ** The --null option disabled handling of tar options in list files. This
461 ** Fixed record size autodetection. If the detected record size differs from
462 the expected value (either default one, or the one set from the
463 command line), tar always prints a warning if verbosity level is set
464 to 1 or greater, i.e. if either -t or -v option is given.
468 version 1.20 - Sergey Poznyakoff, 2008-04-14
470 * New option --auto-compress (-a)
472 With --create, selects compression algorithm basing on the suffix
473 of the archive file name.
477 Selects LZMA compression algorithm
479 * New option --hard-dereference
481 During archive creation, dereferences hard links and stores the files
482 they refer to, instead of creating usual hard link members (type '1').
484 * New option --checkpoint-action
486 This action allows to specify an action to be executed upon hitting a
487 checkpoint. Recognized actions are: dot, echo (the default),
488 echo=string, ttyout=string, exec=cmdline, and sleep=value. Any number
489 of '--checkpoint-action' options can be specified, the actions will be
490 executed in order of their appearance in the command line. See
491 chapter 3.8 "Checkpoints" for a complete description.
493 * New options --no-check-device, --check-device.
495 The '--no-check-device' option disables comparing device numbers during
496 preparatory stage of an incremental dump. This allows to avoid
497 creating full dumps if the device numbers change (e.g. when using an
500 The '--check-device' option enables comparing device numbers. This is
501 the default. This option is provided to undo the effect of the previous
502 '--no-check-device' option, e.g. if it was set in TAR_OPTIONS
503 environment variable.
505 * The --transform option.
507 Any number of '--transform' options can be given in the command line.
508 The specified transformations will be applied in turn.
510 The argument to '--transform' option can be a list of replace
511 expressions, separated by a semicolon (as in 'sed').
513 Filename transformations are applied to symbolic link targets
514 during both creation and extraction. Tar 1.19 used them only
517 For a detailed description, see chapter 6.7 "Modifying File and Member
520 * Info (end-of-volume) scripts
522 The value of the blocking factor is made available to info and
523 checkpoint scripts via environment variable TAR_BLOCKING_FACTOR.
525 * Incremental archives
527 Improved (sped up) extracting from incremental archives.
530 ** Fix bug introduced in version 1.19: tar refused to update non-existing
534 version 1.19 - Sergey Poznyakoff, 2007-10-10
536 * New option --exclude-vcs
538 Excludes directories and files, created by several widely used version
539 control systems, e.g. "CVS/", ".svn/", etc.
541 * --exclude-tag and --exclude-cache options
543 The following options now work with incremental archives as well:
551 * Fix handling of renamed files in listed incremental archives.
553 Previous versions always stored absolute file names in rename
554 records, even if -P was not used. This is fixed: rename records
555 contain file names processed in accordance with the command line
558 * Fix --version output.
560 * Recognition of broken archives.
562 When supplied an archive smaller than 512 bytes in reading mode (-x,
563 -t), the previous version of tar silently ignored it, exiting with
564 code 0. It is fixed. Tar now issues the following diagnostic message:
565 'This does not look like a tar archive', and exits with code 2.
567 * Fix double-dot recognition in archive member names in case of duplicate '/.'.
569 * Fix file padding in case of truncation of the input file to zero size.
572 version 1.18 - Sergey Poznyakoff, 2007-06-29
574 * Licensed under the GPLv3
576 * Fixed several bugs in the testsuite
579 version 1.17 - Sergey Poznyakoff, 2007-06-08
581 * Fix archivation of sparse files in posix mode. Previous versions padded
582 sparse members with spurious zero blocks.
584 * Fix operation of --verify --listed-incremental. Version 1.16.1 produced
585 a full dump when both options were given.
587 * Fix --occurrence. In previous versions it continued scanning the archive
588 even though all requested members has already been extracted.
590 * Scope of --transform and --strip-components options.
592 In addition to affecting regular archive members, the --transform
593 option affects hard and soft link targets and the --strip-components
594 option affects hard link targets as well.
596 * End-of-volume script can send the new volume name to tar by writing
597 it to the file descriptor stored in the environment variable TAR_FD.
600 version 1.16.1 - Sergey Poznyakoff, 2006-12-09
602 * New option --exclude-tag allows to specify "exclusion tag files", i.e.
603 files whose presence in a directory means that the directory should not
606 * The --exclude-cache option excludes directories that contain the
607 CACHEDIR.TAG file from being archived. Previous versions excluded
608 directory contents only, while the directories themselves were
609 still added to the archive.
611 * Support for reading ustar type 'N' header logical records has been removed.
612 This GNU extension was generated only by very old versions of GNU 'tar'.
613 Unfortunately its implementation had security holes; see
614 <http://archives.neohapsis.com/archives/fulldisclosure/2006-11/0344.html>.
615 We don't expect that any tar archives in practical use have type 'N'
616 records, but if you have one and you trust its contents, you can
617 decode it with GNU tar 1.16 or earlier.
619 * Race conditions have been fixed that in some cases briefly allowed
620 files extracted by 'tar -x --same-owner' (or plain 'tar -x', when
621 running as root) to be accessed by users that they shouldn't have been.
624 version 1.16 - Sergey Poznyakoff, 2006-10-21
626 * After creating an archive, tar exits with code 1 if some files were
627 changed while being read. Previous versions exited with code 2 (fatal
628 error), and only if some files were truncated while being archived.
630 * New option --mtime allows to set modification times for all archive
631 members during creation.
634 ** Avoid running off file descriptors when using multiple -C options.
635 ** tar --index-file=FILE --file=- sent the archive to FILE, and
636 the listing to stderr.
639 version 1.15.91 - Sergey Poznyakoff, 2006-06-16
641 * Incompatible changes
645 Previous versions of GNU tar assumed shell-style globbing when
646 extracting from or listing an archive. For example:
650 would extract all files whose names end in '.c'. This behavior
651 was not documented and was incompatible with traditional tar
652 implementations. Therefore, starting from this version, GNU tar
653 no longer uses globbing by default. For example, the above invocation
654 is now interpreted as a request to extract from the archive the file
657 To treat member names as globbing patterns, use --wildcards option.
658 If you wish tar to mimic the behavior of versions up to 1.15.90,
659 add --wildcards to the value of the environment variable TAR_OPTIONS.
661 The exact way in which tar interprets member names is controlled by the
662 following command line options:
664 --wildcards use wildcards
665 --anchored patterns match file name start
666 --ignore-case ignore case
667 --wildcards-match-slash wildcards match '/'
669 Each of these options has a '--no-' counterpart that disables its
670 effect (e.g. --no-wildcards).
672 These options affect both the interpretation of member names from
673 command line and that of the exclusion patterns (given with --exclude
674 and --exclude-from options). The defaults are:
676 1. For member names: --no-wildcards --anchored
677 2. For exclusion patterns: --wildcards --no-anchored --wildcards-match-slash
679 The options can appear multiple times in the command line, thereby
680 changing the way command line arguments are interpreted. For example,
681 to use case-insensitive matching in exclude patterns and to revert to
682 case-sensitive matching for the rest of command line, one could write:
684 tar xf foo.tar --ignore-case --exclude-from=FILE --no-ignore-case file.name
686 ** Short option -l is now an alias of --check-links option, which complies
687 with UNIX98. This ends the transition period started with version 1.14.
691 ** New option --transform allows to transform file names before storing them
692 in the archive or member names before extracting. The option takes a
693 sed replace expression as its argument. For example,
695 tar cf foo.tar --transform 's,^,prefix/,'
697 will add 'prefix/' to all file names stored in foo.tar.
699 ** --strip-components option works when deleting and comparing. In previous
700 versions it worked only with --extract.
702 ** New option --show-transformed-names enables display of transformed file
703 or archive. It generalizes --show-stored-names option, introduced in
704 1.15.90. In particular, when creating an archive in verbose mode, it lists
705 member names as stored in the archive, i.e., with any eventual prefixes
706 removed and file name transformations applied. The option is useful,
707 for example, while comparing 'tar cv' and 'tar tv' outputs.
709 ** New incremental snapshot file format keeps information about file names
710 as well as that about directories.
712 ** The --checkpoint option takes an optional argument specifying the number
713 of records between the two successive checkpoints. Optional dot
714 starting the argument intructs tar to print dots instead of textual
717 ** The --totals option can be used with any tar operation (previous versions
718 understood it only with --create). If an argument to this option is
719 given, it specifies the signal upon delivery of which the statistics
720 is to be printed. Both forms of this option (with and without
721 argument) can be given to in a single invocation of tar.
724 ** Detect attempts to update compressed archives.
727 version 1.15.90 - Sergey Poznyakoff, 2006-02-19
731 ** Any number of -T (--files-from) options may be used in the command line.
732 The file specified with -T may include any valid 'tar' options,
733 including another -T option.
734 Compatibility note: older versions of tar would only recognize -C
735 as an option name within the file list file. Now any file whose name
736 starts with - is handled as an option. To insert file names starting with
737 dash, use the --add-file option.
739 ** List files containing null-separated file names are detected and processed
740 automatically. It is no longer necessary to give the --null option.
742 ** New option --no-unquote disables the unquoting of input file names.
743 This is useful for processing output from 'find dir -print0'.
744 An orthogonal option --unquote is provided as well.
746 ** New option --test-label tests the archive volume label.
747 If an argument is specified, the label is compared against its value.
748 Tar exits with code 0 if the two strings match, and with code 2 if
751 If no argument is given, the --verbose option is implied. In this case,
752 tar prints the label name if present and exits with code 0.
754 ** New option --show-stored-names. When creating an archive in verbose mode,
755 it lists member names as stored in the archive, i.e., with any eventual
756 prefixes removed. The option is useful, for example, while comparing
757 'tar cv' and 'tar tv' outputs.
759 ** New option --to-command pipes the contents of archive members to the
762 ** New option --atime-preserve=system, which uses the O_NOATIME feature
763 of recent Linux kernels to avoid some problems when preserving file
766 ** New option --delay-directory-restore delays restoring modification times
767 and permissions of extracted directories until the end of extraction.
768 This is necessary for restoring from archives with unusual member
769 ordering (in particular, those created with --no-recursion option).
770 This option is implied when restoring from incremental archives.
772 ** New option --restrict prohibits use of some potentially harmful tar
773 options. Currently it disables '!' escape in multi-volume name menu.
775 ** New options --quoting-style and --quote-chars control the way tar
776 quotes member names on output. The --quoting-style takes an argument
777 specifying the quoting style to use (literal, shell, shell-always,
778 c, escape, locale, clocale). The argument to --quote-chars is a string
779 specifying characters to quote, even if the selected quoting style
780 would not quote them otherwise. The option --no-quote-chars is
781 provided to disable quoting certain characters.
783 ** The end-of-volume script (introduced with --info-script option) can
784 get current archive name from the environment variable TAR_ARCHIVE and
785 the volume number from the variable TAR_VOLUME. It can alter the
786 archive name by writing new name to the file descriptor 3.
788 ** Better support for full-resolution time stamps. Tar cannot restore
789 time stamps to full nanosecond resolution, though, until the kernel
790 guys get their act together and give us a system call to set file time
791 stamps to nanosecond resolution.
793 ** The -v option now prints time stamps only to 1-minute resolution,
794 not full resolution, to avoid using up too many output columns.
795 Nanosecond resolution is now supported, but that would be too much.
799 ** Allow non-option arguments to be interspersed with options.
800 ** When extracting or listing archives in old GNU format, tar
801 used to read an extra block of data after a long name header
802 if length of the member name was divisible by block size (512).
803 Consequently, the file pointer was set off and the next member
804 was not processed correctly.
805 ** Previous version created invalid archives when files shrink
807 ** Compare mode (tar d) hung when trying to compare file contents.
808 ** Previous versions in certain cases failed to restore directory
810 ** When creating an archive, do not attempt to store files whose
811 meta-data cannot be stored in the header due to format limitations
812 (for ustar and v7 formats).
813 ** The --version option now also outputs information about copyright,
814 license, and credits. This reverts to the behavior of tar 1.14 and
815 earlier, and conforms to the GNU coding standards. The --license (-L)
816 option introduced in tar 1.15 has been removed, since it's no longer
820 version 1.15.1 - Sergey Poznyakoff, 2004-12-21
822 This version fixes a bug introduced in 1.15 which caused
823 tar to refuse to extract files from standard input.
826 version 1.15 - Sergey Poznyakoff, 2004-12-20
828 * Compressed archives are recognised automatically, it is no longer
829 necessary to specify -Z, -z, or -j options to read them. Thus, you can
830 now run 'tar tf archive.tar.gz'.
832 * When restoring incremental dumps, --one-file-system option
833 prevents directory hierarchies residing on different devices
836 With the previous versions of tar it was dangerous to create
837 incremental dumps with --one-file-system option, since they
838 would recursively remove mount points when restoring from the
839 back up. This change fixes the bug.
841 * Renamed --strip-path to --strip-components for consistency with
844 * Skipping archive members is sped up if the archive media supports
847 * Restore script starts restoring only if it is given --all (-a) option,
848 or some patterns. This is to prevent accidental restores.
850 * 'tar --verify' prints a warning if during archive creation some of
851 the file names had their prefixes stripped off.
853 * New option --exclude-caches instructs tar to exclude cache directories
854 automatically on archive creation. Cache directories are those
855 containing a standardized tag file, as specified at:
857 http://www.brynosaurus.com/cachedir/spec.html
859 * New configure option --with-rmt allows to specify full path name to
860 the 'rmt' utility. This supersedes DEFAULT_RMT_COMMAND variable
861 introduced in version 1.14
863 * New configure variable DEFAULT_RMT_DIR allows to specify the directory
864 where to install 'rmt' utility. This is necessary since modifying
865 --libexecdir as was suggested for version 1.14 produced a side effect: it
866 also modified installation prefix for backup scripts (if
867 --enable-backup-scripts was given).
870 ** Fixed flow in recognizing files to be included in incremental dumps.
871 ** Correctly recognize sparse archive members when used with -T option.
872 ** GNU multivolume headers cannot store filenames longer than 100 characters.
873 Do not allow multivolume archives to begin with such filenames.
874 ** If a member with link count > 2 was stored in the archive twice,
875 previous versions of tar were not able to extract it, since they
876 were trying to link the file to itself, which always failed and
877 lead to removing the already extracted copy. Preserve the first
878 extracted copy in such cases.
879 ** Restore script was passing improper argument to tar --listed option (which
880 didn't affect the functionality, but was logically incorrect).
881 ** Fixed verification of created archives.
882 ** Fixed unquoting of file names containing backslash escapes (previous
883 versions failed to recognize \a and \v).
884 ** When attempting to delete a non-existing member from the archive, previous
885 versions of tar used to overwrite last archive block with zeroes.
888 version 1.14 - Sergey Poznyakoff, 2004-05-11
890 * Added support for POSIX.1-2001 and ustar archive formats.
891 * New option --format allows to select the output archive format
892 * The default output format can be selected at configuration time
893 by presetting the environment variable DEFAULT_ARCHIVE_FORMAT.
894 Allowed values are GNU, V7, OLDGNU and POSIX.
895 * New option --strip-path allows to cut off a given number of
896 path elements from the name of the file being extracted.
898 * New options --index-file, --no-overwrite-dir. The --overwrite-dir
899 option is now the default; use --no-overwrite-dir if you prefer
900 the previous default behavior.
902 * The semantics of -o option is changed. When extracting, it
903 does the same as --no-same-owner GNU tar option. This is compatible
904 with UNIX98 tar. Otherwise, its effect is the same as that of
905 --old-archive option. This latter is deprecated and will be removed
908 * New option --check-links prints a message if not all links are dumped
909 for a file being archived. This corresponds to the UNIX98 -l option.
910 The current semantics of the -l option is retained for compatibility
911 with previous releases, however such usage is strongly deprecated as
912 the option will change to its UNIX98 semantics in the future releases.
914 * New option --occurrence[=N] can be used in conjunction with one of
915 the subcommands --delete, --diff, --extract or --list when a list of
916 files is given either on the command line or via -T option. This
917 option instructs tar to process only the Nth occurrence of each named
918 file. N defaults to 1, so 'tar -x -f archive --occurrence filename'
919 extracts the first occurrence of 'filename' from 'archive'
920 and terminates without scanning to the end of the archive.
922 * New option --pax-option allows to control the handling of POSIX
923 keywords in 'pax' extended headers. It is equivalent to 'pax'
926 * --incremental and --listed-incremental options work correctly on
927 individual files, as well as on directories.
929 * New scripts: backup (replaces old level-0 and level-1) and restore.
930 The scripts are compiled and installed if --enable-backup-scripts
931 option is given to configure.
933 * By default tar searches "rmt" utility in "$prefix/libexec/rmt",
934 which is consistent with the location where the version of "rmt"
935 included in the package is installed. Previous versions of tar
936 used "/etc/rmt". To install "rmt" to its traditional location,
937 run configure with option --libexecdir=/etc. Otherwise, if you
938 already have rmt installed and wish to use it, instead of the
939 shipped in version, set the variable DEFAULT_RMT_COMMAND to
940 the full path name of the utility, e.g., ./configure
941 DEFAULT_RMT_COMMAND=/etc/rmt.
943 Notice also that the full path name of the "rmt" utility to
944 use can be set at runtime, by giving option --rmt-command to
947 * Removed obsolete command line options:
948 ** --absolute-paths superseded by --absolute-names
949 ** --block-compress is not needed any longer
950 ** --block-size superseded by --blocking-factor
951 ** --modification-time superseded by --touch
952 ** --read-full-blocks superseded by --read-full-records
953 ** --record-number superseded by --block-number
954 ** --version-control superseded by --backup
956 * New message translations fi (Finnish), gl (Galician), hr (Croatian),
957 hu (Hungarian), ms (Malaysian), nb (Norwegian), ro (Romanian), sk
958 (Slovak), zh_CN (Chinese simplified), zh_TW (Chinese traditional).
959 The code 'no' for Norwegian (Bokmål) has been withdrawn; use 'nb' instead.
964 version 1.13.25 - Paul Eggert, 2001-09-26
969 version 1.13.24 - Paul Eggert, 2001-09-22
971 * New option --overwrite-dir.
972 * Fixes for buffer overrun, porting, and copyright notice problems.
973 * The message translations for Korean are available again.
976 version 1.13.23 - Paul Eggert, 2001-09-13
978 * Bug, porting, and copyright notice fixes.
981 version 1.13.22 - Paul Eggert, 2001-08-29
986 version 1.13.21 - Paul Eggert, 2001-08-28
988 * Porting and copyright notice fixes.
991 version 1.13.20 - Paul Eggert, 2001-08-27
993 * Some bugs were fixed:
995 - hard links to symbolic links
997 * New option --recursion (the default) that is the inverse of --no-recursion.
999 * New options --anchored, --ignore-case, --wildcards,
1000 --wildcards-match-slash, and their negations (e.g., --no-anchored).
1001 Along with --recursion and --no-recursion, these options control how
1002 exclude patterns are interpreted.
1004 * The default interpretation of exclude patterns is now --no-anchored
1005 --no-ignore-case --recursion --wildcards --wildcards-match-slash.
1006 This is a quiet change to the semantics of --exclude. The previous
1007 semantics were a failed attempt at backward compatibility but it
1008 became clear that the semantics were puzzling and did not satisfy
1009 everybody. Rather than continue to try to revive that dead horse we
1010 thought it better to substitute cleaner semantics, with options so
1011 that you can change the behavior more to your liking.
1013 * New message translations for Indonesian and Turkish.
1014 The translation for Korean has been withdrawn due to encoding errors.
1015 It will be reissued once those are fixed.
1018 version 1.13.19 - Paul Eggert, 2001-01-13
1020 * The -I option has been withdrawn, as it was buggy and confusing.
1021 Eventually it is planned to be reintroduced, with the same meaning as -T.
1023 * With an option like -N DATE, if DATE starts with "/" or ".", it is taken
1024 to be a file name; the last-modified time of that file is used as the date.
1027 version 1.13.18 - Paul Eggert, 2000-10-29
1029 * Some security problems have been fixed. 'tar -x' now modifies only
1030 files under the working directory, unless you also specify an unsafe
1031 option like --absolute-names or --overwrite.
1033 * The short name of the --bzip option has been changed to -j,
1034 and -I is now an alias for -T, for compatibility with Solaris tar.
1036 * The manual is now distributed under the GNU Free Documentation License.
1038 * The new environment variable TAR_OPTIONS holds default command-line options.
1040 * The --no-recursion option now affects extraction too.
1042 * The wording in some diagnostics has been changed slightly.
1044 * Snapshot files now record whether each file was accessed via NFS.
1045 The new file format is upward- and downward-compatible with the old.
1047 * New language supported: da.
1049 * Compilation by traditional (K&R) C compilers is no longer supported.
1050 If you still use such a compiler, please use GCC instead.
1052 * This version of tar works best with GNU gzip test version 1.3 or later.
1053 Please see <ftp://alpha.gnu.org/gnu/gzip/>.
1055 * 'tar --delete -f -' now works again.
1058 version 1.13.17 - Paul Eggert, 2000-01-07.
1060 * 'tar --delete -f -' is no longer allowed; it was too buggy.
1061 * Diagnostic messages have been made more regular and consistent.
1064 version 1.13.16 - Paul Eggert, 1999-12-13.
1066 * By default, tar now refuses to overwrite an existing file when
1067 extracting files from an archive; instead, it removes the file
1068 before extracting it. If the existing file is a symbolic link, the
1069 link is removed and not the pointed-to file. There is one
1070 exception: existing nonempty directories are not removed, nor are
1071 their ownerships or permissions extracted. This fixes some
1072 longstanding security problems.
1074 The new --overwrite option enables the old default behavior.
1076 For regular files, tar implements this change by using the O_EXCL
1077 option of 'open' to ensure that it creates the file; if this fails, it
1078 removes the file and tries again. This is similar to the behavior of
1079 the --unlink-first option, but it is faster in the common case of
1080 extracting a new directory.
1082 * By default, tar now ignores file names containing a component of '..'
1083 when extracting, and warns about such file names when creating an archive.
1084 To enable the old behavior, use the -P or --absolute-names option.
1086 * Tar now handles file names with multibyte encodings (e.g., UTF-8, Shift-JIS)
1087 correctly. It relies on the mbrtowc function to handle multibyte characters.
1089 * The file generated by -g or --listed-incremental now uses a format
1090 that is independent of locale, so that users need not worry about
1091 locale when restoring a backup. This is needed for proper support
1092 of multibyte characters. Old-format files can still be read, and
1093 older versions of GNU tar can read new-format files, unless member
1094 names have multibyte chars.
1096 * Many diagnostics have been changed slightly, so that file names are
1097 now output unambiguously. File names in diagnostics now are either
1098 `quoted like this' (in the default C locale) or are followed by
1099 colon, newline, or space, depending on context. Unprintable
1100 characters are escaped with a C-like backslash conventions.
1101 Terminating characters (e.g., close-quote, colon, newline)
1102 are also escaped as needed.
1104 * tar now ignores socket files when creating an archive.
1105 Previously tar archived sockets as fifos, which caused problems.
1108 version 1.13.15 - Paul Eggert, 1999-12-03.
1110 * If a file's ctime changes when being archived, report an error.
1111 Previously tar looked at mtime, which missed some errors.
1114 version 1.13.14 - Paul Eggert, 1999-11-07.
1116 * New translations ja, pt_BR.
1117 * New options --help and --version for rmt.
1118 * Ignore Solaris door files when creating an archive.
1121 version 1.13.13 - Paul Eggert, 1999-10-11.
1123 * Invalid headers in tar files now elicit errors, not just warnings.
1124 * 'tar --version' output conforms to the latest GNU coding standards.
1125 * If you specify an invalid date, 'tar' now substitutes (time_t) -1.
1126 * 'configure --with-dmalloc' is no longer available.
1129 version 1.13.12 - Paul Eggert, 1999-09-24.
1131 * 'tar' now supports hard links to symbolic links.
1133 * New options --no-same-owner, --no-same-permissions.
1135 * --total now also outputs a human-readable size, and a throughput value.
1137 * 'tar' now uses two's-complement base-256 when outputting header
1138 values that are out of the range of the standard unsigned base-8
1139 format. This affects archive members with negative or huge time
1140 stamps or uids, and archive members 8 GB or larger. The new tar
1141 archives cannot be read by traditional tar, or by older versions of
1142 GNU tar. Use the --old-archive option to revert to the old
1143 behavior, which uses unportable representations for negative values,
1144 and which rejects large files.
1146 * On 32-bit hosts, 'tar' now assumes that an incoming time stamp T in
1147 the range 2**31 <= T < 2**32 represents the negative time (T -
1148 2**32). This behavior is nonstandard and is not portable to 64-bit
1149 time_t hosts, so 'tar' issues a warning.
1151 * 'tar' no longer gives up extracting immediately upon discovering
1152 that an archive contains garbage at the end. It attempts to extract
1153 as many files as possible from the good data before the garbage.
1155 * A read error now causes a nonzero exit status, not just a warning.
1157 * Some diagnostics have been reworded for consistency.
1160 version 1.13.11 - Paul Eggert, 1999-08-23.
1162 * The short name of the --bzip option has been changed to -I,
1163 for compatibility with paxutils.
1165 * -T /dev/null now matches nothing; previously, it matched anything
1166 if no explicit operands were given.
1168 * The '--' option now works the same as with other GNU utilities;
1169 it causes later operands to be interpreted as file names, not options,
1170 even if they begin with '-'.
1172 * For the --newer and --after-date options, the table of time zone
1173 abbreviations like 'EST' has been updated to match current practice.
1174 Also, local time abbreviations are now recognized, even if they are
1175 not in tar's hardwired table. Remember, though, that you should use
1176 numeric UTC offsets like '-0500' instead of abbreviations like
1177 'EST', as abbreviations are not standardized and are ambiguous.
1180 version 1.13.10 - Paul Eggert, 1999-08-20.
1182 * 'tar' now uses signed base-64 when outputting header values that are
1183 out of the range of the standard unsigned base-8 format. [This
1184 change was superseded in 1.13.12, described above.]
1187 version 1.13.9 - Paul Eggert, 1999-08-18.
1189 * 'tar' now writes two zero blocks at end-of-archive instead of just one.
1190 POSIX.1 requires this, and some other 'tar' implementations check for it.
1192 * 'tar' no longer silently accepts a block containing nonzero checksum bytes
1195 * 'tar' now reads buggy tar files that have a null byte at the start of a
1196 numeric header field.
1199 version 1.13.8 - Paul Eggert, 1999-08-16.
1201 * For compatibility with traditional 'tar', intermediate directories
1202 created automatically by root are no longer given the uid and gid of
1203 the original file or directory.
1206 version 1.13.7 - Paul Eggert, 1999-08-14.
1208 * --listed-incremental and --newer are now incompatible options.
1210 * When creating an archive, leading './' is no longer stripped,
1211 to match traditional tar's behavior (and simplify the documentation).
1213 * --diff without --absolute-names no longer falls back on absolute names.
1216 version 1.13.6 - Paul Eggert, 1999-08-11.
1218 * An --exclude pattern containing / now excludes a file only if it matches an
1219 initial prefix of the file name; a pattern without / continues to
1220 exclude a file if it matches any file name component.
1222 * The protocol for talking to rmt has been extended slightly.
1223 Open flags are now communicated in symbolic format as well as numeric.
1224 The symbolic format (e.g., "O_WRONLY|O_CREAT|O_TRUNC") is for portability
1225 when rmt is operating on a different operating system from tar.
1226 The numeric format is retained, and rmt uses it if symbolic format is absent,
1227 for backward compatibility with older versions of tar and rmt.
1229 * When writing GNU tar format headers, tar now uses signed base-64
1230 for values that cannot be represented in unsigned octal.
1231 This supports larger files (2**66 - 1 bytes instead of 2**33 - 1 bytes),
1232 larger uids, negative time stamps, etc.
1234 * When extracting files with unknown ownership, tar now looks up the
1235 uid and gid "nobody" on hosts whose headers do not define UID_NOBODY
1236 and GID_NOBODY, and falls back on uid/gid -2 if there is no "nobody".
1238 * tar -t --numeric-owner now prints numeric uids and gids, not symbolic.
1240 * New option -y or --bzip2 for bzip2 compression, by popular request.
1243 version 1.13.5 - Paul Eggert, 1999-07-20.
1245 * Do the delayed updates of file metadata even after a fatal error.
1248 version 1.13.4 - Paul Eggert, 1999-07-20.
1250 * Do not chmod unless we are root or the -p option was given;
1251 this matches historical practice.
1254 version 1.13.3 - Paul Eggert, 1999-07-16.
1256 * A path name is excluded if any of its file name components matches an
1257 excluded pattern, even if the path name was specified on the command line.
1258 Also see 1.13.6 for later changes in this area.
1261 version 1.13.2 - Paul Eggert, 1999-07-14.
1263 * Bug reporting address changed to <bug-tar@gnu.org>.
1266 version 1.13.1 - Paul Eggert, 1999-07-12.
1270 version 1.13 - Paul Eggert, 1999-07-08.
1272 * Support for large files, e.g., files larger than 2 GB on many 32-bit hosts.
1273 Also, support for larger uids, device ids, etc.
1274 * Many bug fixes and porting fixes.
1275 * This release is only for fixes. A more ambitious test release,
1276 with new features, is available as part of the paxutils. Please see:
1277 ftp://alpha.gnu.org/gnu/paxutils/
1278 The fixes in this release are intended to be merged with paxutils
1279 at some point, but they haven't been merged yet.
1280 * An interim GNU tar alpha had new --bzip2 and --ending-file options,
1281 but they have been removed to maintain compatibility with paxutils.
1282 Please try --use=bzip2 instead of --bzip2.
1284 Version 1.12 - François Pinard, 1997-04.
1287 * Use shell globbing patterns for --label, instead of regular expressions.
1288 * Do not quote anymore internally over the quoting done by the shell.
1291 * Offer internationalization capabilities of most recent GNU gettext.
1292 * Messages available in many more languages, thanks to all translators!
1293 * Usage of ISO 8601 dates in listings, instead of local American dates.
1294 * More normalization and cleanup in error messages.
1297 * For helping using tar with find, offer a --no-recursion option.
1298 * Implement --numeric-owner for ignoring symbolic names at create time.
1299 * New --owner, --group --mode options, still preliminary.
1300 * Recognize creating an archive on /dev/null, so Amanda works faster.
1301 * Object to the creation of an empty archive (like in 'tar cf FILE').
1302 * Barely start implementing --posix and POSIXLY_CORRECT.
1305 * Make a better job at restoring file and directory attributes.
1306 * Automatically attempt deleting existing files when in the way.
1307 * Option --unlink-first (-U) removes most files prior to extraction.
1308 * Option --recursive-unlink removes non-empty directories when in the way.
1309 * Option --numeric-owner ignores owner/group names, it uses UID/GID instead.
1310 * Use global umask when creating missing intermediate directories.
1311 * When symlinks are not available, extract symbolic links as hard links.
1312 * Diagnose extraction of contiguous files as regular files.
1313 * New --backup, --suffix and --version-control options.
1316 * Better support of huge archives with --tape-length and --totals.
1317 * Rename option --read-full-blocks (-B) to --read-full-records (-B).
1318 * Rename option --block-size (-b) to --blocking-factor (-b).
1319 * Rename option --record-number (-R) to --block-number (-R).
1320 * With --block-number (-R), report null blocks and end of file.
1321 * Implement --record-size for introducing a size in bytes.
1322 * Delete --block-compress option and rather decide it automatically.
1323 * Rename option --modification-time to --touch.
1325 Many bugs are squashed, while others still run free.
1327 Version 1.11.8 - François Pinard, 1995-06.
1329 * Messages available in French, German, Portuguese and Swedish.
1330 * The distribution provides a rudimentary Texinfo manual.
1331 * The device defaults to stdin/stdout, unless overridden by the installer.
1332 * Option --sparse (-S) should work on more systems.
1333 * Option --rsh-command may select an alternative remote shell program.
1335 Most changes are internal, and should yield better portability.
1337 Version 1.11.2 - Michael Bushnell, 1993-03.
1339 * Changes in backup scripts: cleaned up considerably; notices error
1340 conditions better over rsh; DUMP_REMIND_SCRIPT is now an option in
1341 backup-specs; new file dump-remind is an example of a
1344 * Superfluous "Reading dirname" was a bug; fixed.
1346 * Incompatibility problems with a bug on Solaris are fixed.
1348 * New option --gzip (aliases are --ungzip and -z); calls gzip instead
1349 of compress. Also, --use-compress-program lets you specify any
1350 compress program. --compress-block is renamed --block-compress and
1351 now requires one of the three compression options to be specified.
1353 * Several error messages are cleaned up.
1355 * Directory owners are now set properly when running as root.
1357 * Provide DUMP_REMIND_SCRIPT in backup-specs as a possible option
1360 * Behave better with broken rmt servers.
1362 * Dump scripts no longer use --atime-preserve; this causes a nasty probem.
1364 * Several Makefile cleanups.
1366 Version 1.11.1 - Michael Bushnell, 1992-09.
1370 Version 1.11 - Michael Bushnell, 1992-09.
1371 Version 1.10.16 - 1992-07.
1372 Version 1.10.15 - 1992-06.
1373 Version 1.10.14 - 1992-05.
1374 Version 1.10.13 - 1992-01.
1378 * Now uses GNU standard configure, generated by Autoconf.
1380 * Long options now use '--'; use of '+' is deprecated and support
1381 for it will eventually be removed.
1383 * New option --null causes filenames read by -T to be
1384 null-terminated, and causes -C to be ignored.
1386 * New option --remove-files deletes files (but not directories)
1387 after they are added to the archive.
1389 * New option --ignore-failed-read prevents read-errors from affecting
1392 * New option --checkpoint prints occasional messages as the tape
1393 is being read or written.
1395 * New option --show-omitted-dirs prints the names of directories
1396 omitted from the archive.
1398 * Some tape drives which use a non-standard method of indicating
1399 end-of-tape now work correctly with multi-tape archives.
1401 * --volno-file: Read the volume number used in prompting the user
1402 (but not in recording volume ID's on the archive) from a file.
1404 * When using --multi-volume, you can now give multiple -f arguments;
1405 the various tape drives will get used in sequence and then wrap
1406 around to the beginning.
1408 * Remote archive names no longer have to be in /dev: any file with a
1409 ':' is interpreted as remote. If new option --force-local is given,
1410 then even archive files with a ':' are considered local.
1412 * New option --atime-preserve restores (if possible) atimes to
1413 their original values after dumping the file.
1415 * No longer does tar confusingly dump "." when you don't tell it
1418 * When extracting directories, tar now correctly restores their
1419 modification and access times.
1421 * Longnames support is redone differently--long name info directly
1422 precedes the long-named file or link in the archive, so you no
1423 longer have to wait for the extract to hit the end of the tape for
1426 Version 1.10 - Michael Bushnell, 1991-07.
1428 * Filename to -G is optional. -C works right. Names +newer and
1429 +newer-mtime work right.
1431 * -g is now +incremental, -G is now +listed-incremental.
1433 * Sparse files now work correctly.
1435 * +volume is now called +label.
1437 * +exclude now takes a filename argument, and +exclude-from does
1438 what +exclude used to do.
1440 * Exit status is now correct.
1442 * +totals keeps track of total I/O and prints it when tar exits.
1444 * When using +label with +extract, the label is now a regexp.
1446 * New option +tape-length (-L) does multi-volume handling like BSD
1447 dump: you tell tar how big the tape is and it will prompt at that
1448 point instead of waiting for a write error.
1450 * New backup scripts level-0 and level-1 which might be useful
1451 to people. They use a file "backup-specs" for information, and
1452 shouldn't need local modification. These are what we use to do
1453 all our backups at the FSF.
