1 GNU tar NEWS - User visible changes.
2 Please send GNU tar bug reports to <bug-tar@gnu.org>
4 * Support for reading ustar type 'N' header logical records has been removed.
5 This GNU extension was generated only by very old versions of GNU 'tar'.
6 Unfortunately its implementation had security holes; see
7 <http://archives.neohapsis.com/archives/fulldisclosure/2006-11/0344.html>.
8 We don't expect that any tar archives in practical use have type 'N'
9 records, but if you have one and you trust its contents, you can
10 decode it with GNU tar 1.16 or earlier.
12 * Race conditions have been fixed that in some cases briefly allowed
13 files extracted by 'tar -x --same-owner' (or plain 'tar -x', when
14 running as root) to be accessed by users that they shouldn't have been.
16 version 1.16 - Sergey Poznyakoff, 2006-10-21
18 * After creating an archive, tar exits with code 1 if some files were
19 changed while being read. Previous versions exited with code 2 (fatal
20 error), and only if some files were truncated while being archived.
22 * New option --mtime allows to set modification times for all archive
23 members during creation.
26 ** Avoid running off file descriptors when using multiple -C options.
27 ** tar --index-file=FILE --file=- sent the archive to FILE, and
28 the listing to stderr.
31 version 1.15.91 - Sergey Poznyakoff, 2006-06-16
33 * Incompatible changes
37 Previous versions of GNU tar assumed shell-style globbing when
38 extracting from or listing an archive. For example:
42 would extract all files whose names end in '.c'. This behavior
43 was not documented and was incompatible with traditional tar
44 implementations. Therefore, starting from this version, GNU tar
45 no longer uses globbing by default. For example, the above invocation
46 is now interpreted as a request to extract from the archive the file
49 To treat member names as globbing patterns, use --wildcards option.
50 If you wish tar to mimic the behavior of versions up to 1.15.90,
51 add --wildcards to the value of the environment variable TAR_OPTIONS.
53 The exact way in which tar interprets member names is controlled by the
54 following command line options:
56 --wildcards use wildcards
57 --anchored patterns match file name start
58 --ignore-case ignore case
59 --wildcards-match-slash wildcards match `/'
61 Each of these options has a '--no-' counterpart that disables its
62 effect (e.g. --no-wildcards).
64 These options affect both the interpretation of member names from
65 command line and that of the exclusion patterns (given with --exclude
66 and --exclude-from options). The defaults are:
68 1. For member names: --no-wildcards --anchored
69 2. For exclusion patterns: --wildcards --no-anchored --wildcards-match-slash
71 The options can appear multiple times in the command line, thereby
72 changing the way command line arguments are interpreted. For example,
73 to use case-insensitive matching in exclude patterns and to revert to
74 case-sensitive matching for the rest of command line, one could write:
76 tar xf foo.tar --ignore-case --exclude-from=FILE --no-ignore-case file.name
78 ** Short option -l is now an alias of --check-links option, which complies
79 with UNIX98. This ends the transition period started with version 1.14.
83 ** New option --transform allows to transform file names before storing them
84 in the archive or member names before extracting. The option takes a
85 sed replace expression as its argument. For example,
87 tar cf foo.tar --transform 's,^,prefix/,'
89 will add 'prefix/' to all file names stored in foo.tar.
91 ** --strip-components option works when deleting and comparing. In previous
92 versions it worked only with --extract.
94 ** New option --show-transformed-names enables display of transformed file
95 or archive. It generalizes --show-stored-names option, introduced in
96 1.15.90. In particular, when creating an archive in verbose mode, it lists
97 member names as stored in the archive, i.e., with any eventual prefixes
98 removed and file name transformations applied. The option is useful,
99 for example, while comparing `tar cv' and `tar tv' outputs.
101 ** New incremental snapshot file format keeps information about file names
102 as well as that about directories.
104 ** The --checkpoint option takes an optional argument specifying the number
105 of records between the two successive checkpoints. Optional dot
106 starting the argument intructs tar to print dots instead of textual
109 ** The --totals option can be used with any tar operation (previous versions
110 understood it only with --create). If an argument to this option is
111 given, it specifies the signal upon delivery of which the statistics
112 is to be printed. Both forms of this option (with and without
113 argument) can be given to in a single invocation of tar.
116 ** Detect attempts to update compressed archives.
119 version 1.15.90 - Sergey Poznyakoff, 2006-02-19
123 ** Any number of -T (--files-from) options may be used in the command line.
124 The file specified with -T may include any valid `tar' options,
125 including another -T option.
126 Compatibility note: older versions of tar would only recognize -C
127 as an option name within the file list file. Now any file whose name
128 starts with - is handled as an option. To insert file names starting with
129 dash, use the --add-file option.
131 ** List files containing null-separated file names are detected and processed
132 automatically. It is no longer necessary to give the --null option.
134 ** New option --no-unquote disables the unquoting of input file names.
135 This is useful for processing output from `find dir -print0'.
136 An orthogonal option --unquote is provided as well.
138 ** New option --test-label tests the archive volume label.
139 If an argument is specified, the label is compared against its value.
140 Tar exits with code 0 if the two strings match, and with code 2 if
143 If no argument is given, the --verbose option is implied. In this case,
144 tar prints the label name if present and exits with code 0.
146 ** New option --show-stored-names. When creating an archive in verbose mode,
147 it lists member names as stored in the archive, i.e., with any eventual
148 prefixes removed. The option is useful, for example, while comparing
149 `tar cv' and `tar tv' outputs.
151 ** New option --to-command pipes the contents of archive members to the
154 ** New option --atime-preserve=system, which uses the O_NOATIME feature
155 of recent Linux kernels to avoid some problems when preserving file
158 ** New option --delay-directory-restore delays restoring modification times
159 and permissions of extracted directories until the end of extraction.
160 This is necessary for restoring from archives with unusual member
161 ordering (in particular, those created with --no-recursion option).
162 This option is implied when restoring from incremental archives.
164 ** New option --restrict prohibits use of some potentially harmful tar
165 options. Currently it disables '!' escape in multi-volume name menu.
167 ** New options --quoting-style and --quote-chars control the way tar
168 quotes member names on output. The --quoting-style takes an argument
169 specifying the quoting style to use (literal, shell, shell-always,
170 c, escape, locale, clocale). The argument to --quote-chars is a string
171 specifying characters to quote, even if the selected quoting style
172 would not quote them otherwise. The option --no-quote-chars is
173 provided to disable quoting certain characters.
175 ** The end-of-volume script (introduced with --info-script option) can
176 get current archive name from the environment variable TAR_ARCHIVE and
177 the volume number from the variable TAR_VOLUME. It can alter the
178 archive name by writing new name to the file descriptor 3.
180 ** Better support for full-resolution time stamps. Tar cannot restore
181 time stamps to full nanosecond resolution, though, until the kernel
182 guys get their act together and give us a system call to set file time
183 stamps to nanosecond resolution.
185 ** The -v option now prints time stamps only to 1-minute resolution,
186 not full resolution, to avoid using up too many output columns.
187 Nanosecond resolution is now supported, but that would be too much.
191 ** Allow non-option arguments to be interspersed with options.
192 ** When extracting or listing archives in old GNU format, tar
193 used to read an extra block of data after a long name header
194 if length of the member name was divisible by block size (512).
195 Consequently, the file pointer was set off and the next member
196 was not processed correctly.
197 ** Previous version created invalid archives when files shrink
199 ** Compare mode (tar d) hanged when trying to compare file contents.
200 ** Previous versions in certain cases failed to restore directory
202 ** When creating an archive, do not attempt to store files whose
203 meta-data cannot be stored in the header due to format limitations
204 (for ustar and v7 formats).
205 ** The --version option now also outputs information about copyright,
206 license, and credits. This reverts to the behavior of tar 1.14 and
207 earlier, and conforms to the GNU coding standards. The --license (-L)
208 option introduced in tar 1.15 has been removed, since it's no longer
212 version 1.15.1 - Sergey Poznyakoff, 2004-12-21
214 This version fixes a bug introduced in 1.15 which caused
215 tar to refuse to extract files from standard input.
218 version 1.15 - Sergey Poznyakoff, 2004-12-20
220 * Compressed archives are recognised automatically, it is no longer
221 necessary to specify -Z, -z, or -j options to read them. Thus, you can
222 now run `tar tf archive.tar.gz'.
224 * When restoring incremental dumps, --one-file-system option
225 prevents directory hierarchies residing on different devices
228 With the previous versions of tar it was dangerous to create
229 incremental dumps with --one-file-system option, since they
230 would recursively remove mount points when restoring from the
231 back up. This change fixes the bug.
233 * Renamed --strip-path to --strip-components for consistency with
236 * Skipping archive members is sped up if the archive media supports
239 * Restore script starts restoring only if it is given --all (-a) option,
240 or some patterns. This is to prevent accidental restores.
242 * `tar --verify' prints a warning if during archive creation some of
243 the file names had their prefixes stripped off.
245 * New option --exclude-caches instructs tar to exclude cache directories
246 automatically on archive creation. Cache directories are those
247 containing a standardized tag file, as specified at:
249 http://www.brynosaurus.com/cachedir/spec.html
251 * New configure option --with-rmt allows to specify full path name to
252 the `rmt' utility. This supersedes DEFAULT_RMT_COMMAND variable
253 introduced in version 1.14
255 * New configure variable DEFAULT_RMT_DIR allows to specify the directory
256 where to install `rmt' utility. This is necessary since modifying
257 --libexecdir as was suggested for version 1.14 produced a side effect: it
258 also modified installation prefix for backup scripts (if
259 --enable-backup-scripts was given).
262 ** Fixed flow in recognizing files to be included in incremental dumps.
263 ** Correctly recognize sparse archive members when used with -T option.
264 ** GNU multivolume headers cannot store filenames longer than 100 characters.
265 Do not allow multivolume archives to begin with such filenames.
266 ** If a member with link count > 2 was stored in the archive twice,
267 previous versions of tar were not able to extract it, since they
268 were trying to link the file to itself, which always failed and
269 lead to removing the already extracted copy. Preserve the first
270 extracted copy in such cases.
271 ** Restore script was passing improper argument to tar --listed option (which
272 didn't affect the functionality, but was logically incorrect).
273 ** Fixed verification of created archives.
274 ** Fixed unquoting of file names containing backslash escapes (previous
275 versions failed to recognize \a and \v).
276 ** When attempting to delete a non-existing member from the archive, previous
277 versions of tar used to overwrite last archive block with zeroes.
280 version 1.14 - Sergey Poznyakoff, 2004-05-11
282 * Added support for POSIX.1-2001 and ustar archive formats.
283 * New option --format allows to select the output archive format
284 * The default output format can be selected at configuration time
285 by presetting the environment variable DEFAULT_ARCHIVE_FORMAT.
286 Allowed values are GNU, V7, OLDGNU and POSIX.
287 * New option --strip-path allows to cut off a given number of
288 path elements from the name of the file being extracted.
290 * New options --index-file, --no-overwrite-dir. The --overwrite-dir
291 option is now the default; use --no-overwrite-dir if you prefer
292 the previous default behavior.
294 * The semantics of -o option is changed. When extracting, it
295 does the same as --no-same-owner GNU tar option. This is compatible
296 with UNIX98 tar. Otherwise, its effect is the same as that of
297 --old-archive option. This latter is deprecated and will be removed
300 * New option --check-links prints a message if not all links are dumped
301 for a file being archived. This corresponds to the UNIX98 -l option.
302 The current semantics of the -l option is retained for compatibility
303 with previous releases, however such usage is strongly deprecated as
304 the option will change to its UNIX98 semantics in the future releases.
306 * New option --occurrence[=N] can be used in conjunction with one of
307 the subcommands --delete, --diff, --extract or --list when a list of
308 files is given either on the command line or via -T option. This
309 option instructs tar to process only the Nth occurrence of each named
310 file. N defaults to 1, so `tar -x -f archive --occurrence filename'
311 extracts the first occurrence of `filename' from `archive'
312 and terminates without scanning to the end of the archive.
314 * New option --pax-option allows to control the handling of POSIX
315 keywords in `pax' extended headers. It is equivalent to `pax'
318 * --incremental and --listed-incremental options work correctly on
319 individual files, as well as on directories.
321 * New scripts: backup (replaces old level-0 and level-1) and restore.
322 The scripts are compiled and installed if --enable-backup-scripts
323 option is given to configure.
325 * By default tar searches "rmt" utility in "$prefix/libexec/rmt",
326 which is consistent with the location where the version of "rmt"
327 included in the package is installed. Previous versions of tar
328 used "/etc/rmt". To install "rmt" to its traditional location,
329 run configure with option --libexecdir=/etc. Otherwise, if you
330 already have rmt installed and wish to use it, instead of the
331 shipped in version, set the variable DEFAULT_RMT_COMMAND to
332 the full path name of the utility, e.g., ./configure
333 DEFAULT_RMT_COMMAND=/etc/rmt.
335 Notice also that the full path name of the "rmt" utility to
336 use can be set at runtime, by giving option --rmt-command to
339 * Removed obsolete command line options:
340 ** --absolute-paths superseded by --absolute-names
341 ** --block-compress is not needed any longer
342 ** --block-size superseded by --blocking-factor
343 ** --modification-time superseded by --touch
344 ** --read-full-blocks superseded by --read-full-records
345 ** --record-number superseded by --block-number
346 ** --version-control superseded by --backup
348 * New message translations fi (Finnish), gl (Galician), hr (Croatian),
349 hu (Hungarian), ms (Malaysian), nb (Norwegian), ro (Romanian), sk
350 (Slovak), zh_CN (Chinese simplified), zh_TW (Chinese traditional).
351 The code 'no' for Norwegian (Bokmål) has been withdrawn; use 'nb' instead.
356 version 1.13.25 - Paul Eggert, 2001-09-26
361 version 1.13.24 - Paul Eggert, 2001-09-22
363 * New option --overwrite-dir.
364 * Fixes for buffer overrun, porting, and copyright notice problems.
365 * The message translations for Korean are available again.
368 version 1.13.23 - Paul Eggert, 2001-09-13
370 * Bug, porting, and copyright notice fixes.
373 version 1.13.22 - Paul Eggert, 2001-08-29
378 version 1.13.21 - Paul Eggert, 2001-08-28
380 * Porting and copyright notice fixes.
383 version 1.13.20 - Paul Eggert, 2001-08-27
385 * Some bugs were fixed:
387 - hard links to symbolic links
389 * New option --recursion (the default) that is the inverse of --no-recursion.
391 * New options --anchored, --ignore-case, --wildcards,
392 --wildcards-match-slash, and their negations (e.g., --no-anchored).
393 Along with --recursion and --no-recursion, these options control how
394 exclude patterns are interpreted.
396 * The default interpretation of exclude patterns is now --no-anchored
397 --no-ignore-case --recursion --wildcards --wildcards-match-slash.
398 This is a quiet change to the semantics of --exclude. The previous
399 semantics were a failed attempt at backward compatibility but it
400 became clear that the semantics were puzzling and did not satisfy
401 everybody. Rather than continue to try to revive that dead horse we
402 thought it better to substitute cleaner semantics, with options so
403 that you can change the behavior more to your liking.
405 * New message translations for Indonesian and Turkish.
406 The translation for Korean has been withdrawn due to encoding errors.
407 It will be reissued once those are fixed.
410 version 1.13.19 - Paul Eggert, 2001-01-13
412 * The -I option has been withdrawn, as it was buggy and confusing.
413 Eventually it is planned to be reintroduced, with the same meaning as -T.
415 * With an option like -N DATE, if DATE starts with "/" or ".", it is taken
416 to be a file name; the last-modified time of that file is used as the date.
419 version 1.13.18 - Paul Eggert, 2000-10-29
421 * Some security problems have been fixed. `tar -x' now modifies only
422 files under the working directory, unless you also specify an unsafe
423 option like --absolute-names or --overwrite.
425 * The short name of the --bzip option has been changed to -j,
426 and -I is now an alias for -T, for compatibility with Solaris tar.
428 * The manual is now distributed under the GNU Free Documentation License.
430 * The new environment variable TAR_OPTIONS holds default command-line options.
432 * The --no-recursion option now affects extraction too.
434 * The wording in some diagnostics has been changed slightly.
436 * Snapshot files now record whether each file was accessed via NFS.
437 The new file format is upward- and downward-compatible with the old.
439 * New language supported: da.
441 * Compilation by traditional (K&R) C compilers is no longer supported.
442 If you still use such a compiler, please use GCC instead.
444 * This version of tar works best with GNU gzip test version 1.3 or later.
445 Please see <ftp://alpha.gnu.org/gnu/gzip/>.
447 * `tar --delete -f -' now works again.
450 version 1.13.17 - Paul Eggert, 2000-01-07.
452 * `tar --delete -f -' is no longer allowed; it was too buggy.
453 * Diagnostic messages have been made more regular and consistent.
456 version 1.13.16 - Paul Eggert, 1999-12-13.
458 * By default, tar now refuses to overwrite an existing file when
459 extracting files from an archive; instead, it removes the file
460 before extracting it. If the existing file is a symbolic link, the
461 link is removed and not the pointed-to file. There is one
462 exception: existing nonempty directories are not removed, nor are
463 their ownerships or permissions extracted. This fixes some
464 longstanding security problems.
466 The new --overwrite option enables the old default behavior.
468 For regular files, tar implements this change by using the O_EXCL
469 option of `open' to ensure that it creates the file; if this fails, it
470 removes the file and tries again. This is similar to the behavior of
471 the --unlink-first option, but it is faster in the common case of
472 extracting a new directory.
474 * By default, tar now ignores file names containing a component of `..'
475 when extracting, and warns about such file names when creating an archive.
476 To enable the old behavior, use the -P or --absolute-names option.
478 * Tar now handles file names with multibyte encodings (e.g., UTF-8, Shift-JIS)
479 correctly. It relies on the mbrtowc function to handle multibyte characters.
481 * The file generated by -g or --listed-incremental now uses a format
482 that is independent of locale, so that users need not worry about
483 locale when restoring a backup. This is needed for proper support
484 of multibyte characters. Old-format files can still be read, and
485 older versions of GNU tar can read new-format files, unless member
486 names have multibyte chars.
488 * Many diagnostics have been changed slightly, so that file names are
489 now output unambiguously. File names in diagnostics now are either
490 `quoted like this' (in the default C locale) or are followed by
491 colon, newline, or space, depending on context. Unprintable
492 characters are escaped with a C-like backslash conventions.
493 Terminating characters (e.g., close-quote, colon, newline)
494 are also escaped as needed.
496 * tar now ignores socket files when creating an archive.
497 Previously tar archived sockets as fifos, which caused problems.
500 version 1.13.15 - Paul Eggert, 1999-12-03.
502 * If a file's ctime changes when being archived, report an error.
503 Previously tar looked at mtime, which missed some errors.
506 version 1.13.14 - Paul Eggert, 1999-11-07.
508 * New translations ja, pt_BR.
509 * New options --help and --version for rmt.
510 * Ignore Solaris door files when creating an archive.
513 version 1.13.13 - Paul Eggert, 1999-10-11.
515 * Invalid headers in tar files now elicit errors, not just warnings.
516 * `tar --version' output conforms to the latest GNU coding standards.
517 * If you specify an invalid date, `tar' now substitutes (time_t) -1.
518 * `configure --with-dmalloc' is no longer available.
521 version 1.13.12 - Paul Eggert, 1999-09-24.
523 * `tar' now supports hard links to symbolic links.
525 * New options --no-same-owner, --no-same-permissions.
527 * --total now also outputs a human-readable size, and a throughput value.
529 * `tar' now uses two's-complement base-256 when outputting header
530 values that are out of the range of the standard unsigned base-8
531 format. This affects archive members with negative or huge time
532 stamps or uids, and archive members 8 GB or larger. The new tar
533 archives cannot be read by traditional tar, or by older versions of
534 GNU tar. Use the --old-archive option to revert to the old
535 behavior, which uses unportable representations for negative values,
536 and which rejects large files.
538 * On 32-bit hosts, `tar' now assumes that an incoming time stamp T in
539 the range 2**31 <= T < 2**32 represents the negative time (T -
540 2**32). This behavior is nonstandard and is not portable to 64-bit
541 time_t hosts, so `tar' issues a warning.
543 * `tar' no longer gives up extracting immediately upon discovering
544 that an archive contains garbage at the end. It attempts to extract
545 as many files as possible from the good data before the garbage.
547 * A read error now causes a nonzero exit status, not just a warning.
549 * Some diagnostics have been reworded for consistency.
552 version 1.13.11 - Paul Eggert, 1999-08-23.
554 * The short name of the --bzip option has been changed to -I,
555 for compatibility with paxutils.
557 * -T /dev/null now matches nothing; previously, it matched anything
558 if no explicit operands were given.
560 * The `--' option now works the same as with other GNU utilities;
561 it causes later operands to be interpreted as file names, not options,
562 even if they begin with `-'.
564 * For the --newer and --after-date options, the table of time zone
565 abbreviations like `EST' has been updated to match current practice.
566 Also, local time abbreviations are now recognized, even if they are
567 not in tar's hardwired table. Remember, though, that you should use
568 numeric UTC offsets like `-0500' instead of abbreviations like
569 `EST', as abbreviations are not standardized and are ambiguous.
572 version 1.13.10 - Paul Eggert, 1999-08-20.
574 * `tar' now uses signed base-64 when outputting header values that are
575 out of the range of the standard unsigned base-8 format. [This
576 change was superseded in 1.13.12, described above.]
579 version 1.13.9 - Paul Eggert, 1999-08-18.
581 * `tar' now writes two zero blocks at end-of-archive instead of just one.
582 POSIX.1 requires this, and some other `tar' implementations check for it.
584 * `tar' no longer silently accepts a block containing nonzero checksum bytes
587 * `tar' now reads buggy tar files that have a null byte at the start of a
588 numeric header field.
591 version 1.13.8 - Paul Eggert, 1999-08-16.
593 * For compatibility with traditional `tar', intermediate directories
594 created automatically by root are no longer given the uid and gid of
595 the original file or directory.
598 version 1.13.7 - Paul Eggert, 1999-08-14.
600 * --listed-incremental and --newer are now incompatible options.
602 * When creating an archive, leading `./' is no longer stripped,
603 to match traditional tar's behavior (and simplify the documentation).
605 * --diff without --absolute-names no longer falls back on absolute names.
608 version 1.13.6 - Paul Eggert, 1999-08-11.
610 * An --exclude pattern containing / now excludes a file only if it matches an
611 initial prefix of the file name; a pattern without / continues to
612 exclude a file if it matches any file name component.
614 * The protocol for talking to rmt has been extended slightly.
615 Open flags are now communicated in symbolic format as well as numeric.
616 The symbolic format (e.g., "O_WRONLY|O_CREAT|O_TRUNC") is for portability
617 when rmt is operating on a different operating system from tar.
618 The numeric format is retained, and rmt uses it if symbolic format is absent,
619 for backward compatibility with older versions of tar and rmt.
621 * When writing GNU tar format headers, tar now uses signed base-64
622 for values that cannot be represented in unsigned octal.
623 This supports larger files (2**66 - 1 bytes instead of 2**33 - 1 bytes),
624 larger uids, negative time stamps, etc.
626 * When extracting files with unknown ownership, tar now looks up the
627 uid and gid "nobody" on hosts whose headers do not define UID_NOBODY
628 and GID_NOBODY, and falls back on uid/gid -2 if there is no "nobody".
630 * tar -t --numeric-owner now prints numeric uids and gids, not symbolic.
632 * New option -y or --bzip2 for bzip2 compression, by popular request.
635 version 1.13.5 - Paul Eggert, 1999-07-20.
637 * Do the delayed updates of file metadata even after a fatal error.
640 version 1.13.4 - Paul Eggert, 1999-07-20.
642 * Do not chmod unless we are root or the -p option was given;
643 this matches historical practice.
646 version 1.13.3 - Paul Eggert, 1999-07-16.
648 * A path name is excluded if any of its file name components matches an
649 excluded pattern, even if the path name was specified on the command line.
650 Also see 1.13.6 for later changes in this area.
653 version 1.13.2 - Paul Eggert, 1999-07-14.
655 * Bug reporting address changed to <bug-tar@gnu.org>.
658 version 1.13.1 - Paul Eggert, 1999-07-12.
662 version 1.13 - Paul Eggert, 1999-07-08.
664 * Support for large files, e.g., files larger than 2 GB on many 32-bit hosts.
665 Also, support for larger uids, device ids, etc.
666 * Many bug fixes and porting fixes.
667 * This release is only for fixes. A more ambitious test release,
668 with new features, is available as part of the paxutils. Please see:
669 ftp://alpha.gnu.org/gnu/paxutils/
670 The fixes in this release are intended to be merged with paxutils
671 at some point, but they haven't been merged yet.
672 * An interim GNU tar alpha had new --bzip2 and --ending-file options,
673 but they have been removed to maintain compatibility with paxutils.
674 Please try --use=bzip2 instead of --bzip2.
676 Version 1.12 - François Pinard, 1997-04.
679 * Use shell globbing patterns for --label, instead of regular expressions.
680 * Do not quote anymore internally over the quoting done by the shell.
683 * Offer internationalization capabilities of most recent GNU gettext.
684 * Messages available in many more languages, thanks to all translators!
685 * Usage of ISO 8601 dates in listings, instead of local American dates.
686 * More normalization and cleanup in error messages.
689 * For helping using tar with find, offer a --no-recursion option.
690 * Implement --numeric-owner for ignoring symbolic names at create time.
691 * New --owner, --group --mode options, still preliminary.
692 * Recognize creating an archive on /dev/null, so Amanda works faster.
693 * Object to the creation of an empty archive (like in `tar cf FILE').
694 * Barely start implementing --posix and POSIXLY_CORRECT.
697 * Make a better job at restoring file and directory attributes.
698 * Automatically attempt deleting existing files when in the way.
699 * Option --unlink-first (-U) removes most files prior to extraction.
700 * Option --recursive-unlink removes non-empty directories when in the way.
701 * Option --numeric-owner ignores owner/group names, it uses UID/GID instead.
702 * Use global umask when creating missing intermediate directories.
703 * When symlinks are not available, extract symbolic links as hard links.
704 * Diagnose extraction of contiguous files as regular files.
705 * New --backup, --suffix and --version-control options.
708 * Better support of huge archives with --tape-length and --totals.
709 * Rename option --read-full-blocks (-B) to --read-full-records (-B).
710 * Rename option --block-size (-b) to --blocking-factor (-b).
711 * Rename option --record-number (-R) to --block-number (-R).
712 * With --block-number (-R), report null blocks and end of file.
713 * Implement --record-size for introducing a size in bytes.
714 * Delete --block-compress option and rather decide it automatically.
715 * Rename option --modification-time to --touch.
717 Many bugs are squashed, while others still run free.
719 Version 1.11.8 - François Pinard, 1995-06.
721 * Messages available in French, German, Portuguese and Swedish.
722 * The distribution provides a rudimentary Texinfo manual.
723 * The device defaults to stdin/stdout, unless overridden by the installer.
724 * Option --sparse (-S) should work on more systems.
725 * Option --rsh-command may select an alternative remote shell program.
727 Most changes are internal, and should yield better portability.
729 Version 1.11.2 - Michael Bushnell, 1993-03.
731 * Changes in backup scripts: cleaned up considerably; notices error
732 conditions better over rsh; DUMP_REMIND_SCRIPT is now an option in
733 backup-specs; new file dump-remind is an example of a
736 * Superfluous "Reading dirname" was a bug; fixed.
738 * Incompatibility problems with a bug on Solaris are fixed.
740 * New option --gzip (aliases are --ungzip and -z); calls gzip instead
741 of compress. Also, --use-compress-program lets you specify any
742 compress program. --compress-block is renamed --block-compress and
743 now requires one of the three compression options to be specified.
745 * Several error messages are cleaned up.
747 * Directory owners are now set properly when running as root.
749 * Provide DUMP_REMIND_SCRIPT in backup-specs as a possible option
752 * Behave better with broken rmt servers.
754 * Dump scripts no longer use --atime-preserve; this causes a nasty probem.
756 * Several Makefile cleanups.
758 Version 1.11.1 - Michael Bushnell, 1992-09.
762 Version 1.11 - Michael Bushnell, 1992-09.
763 Version 1.10.16 - 1992-07.
764 Version 1.10.15 - 1992-06.
765 Version 1.10.14 - 1992-05.
766 Version 1.10.13 - 1992-01.
770 * Now uses GNU standard configure, generated by Autoconf.
772 * Long options now use `--'; use of `+' is deprecated and support
773 for it will eventually be removed.
775 * New option --null causes filenames read by -T to be
776 null-terminated, and causes -C to be ignored.
778 * New option --remove-files deletes files (but not directories)
779 after they are added to the archive.
781 * New option --ignore-failed-read prevents read-errors from affecting
784 * New option --checkpoint prints occasional messages as the tape
785 is being read or written.
787 * New option --show-omitted-dirs prints the names of directories
788 omitted from the archive.
790 * Some tape drives which use a non-standard method of indicating
791 end-of-tape now work correctly with multi-tape archives.
793 * --volno-file: Read the volume number used in prompting the user
794 (but not in recording volume ID's on the archive) from a file.
796 * When using --multi-volume, you can now give multiple -f arguments;
797 the various tape drives will get used in sequence and then wrap
798 around to the beginning.
800 * Remote archive names no longer have to be in /dev: any file with a
801 `:' is interpreted as remote. If new option --force-local is given,
802 then even archive files with a `:' are considered local.
804 * New option --atime-preserve restores (if possible) atimes to
805 their original values after dumping the file.
807 * No longer does tar confusingly dump "." when you don't tell it
810 * When extracting directories, tar now correctly restores their
811 modification and access times.
813 * Longnames support is redone differently--long name info directly
814 precedes the long-named file or link in the archive, so you no
815 longer have to wait for the extract to hit the end of the tape for
818 Version 1.10 - Michael Bushnell, 1991-07.
820 * Filename to -G is optional. -C works right. Names +newer and
821 +newer-mtime work right.
823 * -g is now +incremental, -G is now +listed-incremental.
825 * Sparse files now work correctly.
827 * +volume is now called +label.
829 * +exclude now takes a filename argument, and +exclude-from does
830 what +exclude used to do.
832 * Exit status is now correct.
834 * +totals keeps track of total I/O and prints it when tar exits.
836 * When using +label with +extract, the label is now a regexp.
838 * New option +tape-length (-L) does multi-volume handling like BSD
839 dump: you tell tar how big the tape is and it will prompt at that
840 point instead of waiting for a write error.
842 * New backup scripts level-0 and level-1 which might be useful
843 to people. They use a file "backup-specs" for information, and
844 shouldn't need local modification. These are what we use to do
845 all our backups at the FSF.

849 Versions 1.07 back to 1.00 by Jay Fenlason.
851 * See ChangeLog for more details.
