4 version 1.15.91 - Sergey Poznyakoff, (CVS version)
5
6 * Incompatible changes
7
8 ** Globbing
9
10 Previous versions of GNU tar assumed shell-style globbing when
11 extracting from or listing an archive. For example:
12
13 tar xf foo.tar '*.c'
14
15 would extract all files whose names end in '.c'. This behavior
16 was not documented and was incompatible with traditional tar
17 implementations. Therefore, starting from this version, GNU tar
18 no longer uses globbing by default. For example, the above invocation
19 is now interpreted as a request to extract from the archive the file
20 named '*.c'.
21
22 To treat member names as globbing patterns, use --wildcards option.
23 So, if you wish tar to mimic the behavior of versions up to 1.15.90,
24 set 'TAR_OPTIONS=--wildcards'.
25
26 The exact way tar interprets member names is controlled by the
27 following command line options:
28
29 --wildcards use wildcards
30 --anchored patterns match file name start
31 --ignore-case ignore case
32 --wildcards-match-slash wildcards match `/'
33
34 Each of these options has a '--no-' counterpart that disables its
35 effect (e.g. --no-wildcards).
36
37 These options affect both the interpretation of member names from
38 command line and that of the exclusion patterns (given with --exclude
39 and --exclude-from options). The defaults are:
40
41 1. For member names: --no-wildcards --anchored
42 2. For exclusion patterns: --wildcards --no-anchored --wildcards-match-slash
43
44 The options can appear multiple times in the command line, thereby
45 changing the way command line arguments are interpreted. For example,
46 to use case-insensitive matching in exclude patterns and to revert to
47 case-sensitive matching for the rest of command line, one could write:
48
49 tar xf foo.tar --ignore-case --exclude-from=FILE --no-ignore-case file.name
50
51 ** Short option -l is now an alias of --check-links option, which complies
52 with UNIX98. This ends the transition period started with version 1.14.
53
54 * New features
55
56 ** New option --transform allows to transform file names before storing them
57 in the archive or member names before extracting. The option takes a
58 sed replace expression as its argument. For example,
59
60 tar cf foo.tar --transform 's,^,prefix/'
61
62 will add 'prefix/' to all file names stored in foo.tar.
63
64 ** --strip-components option works when deleting and comparing.
65
66 ** New option --show-transformed-names enables display of transformed file
67 or archive. In particular, when creating archive in verbose mode,
68 the option lists member names as stored in the archive. It
69 generalizes --show-stored-names option, introduced in 1.15.90. In
70 particular, when creating an archive in verbose mode, it lists member
71 names as stored in the archive, i.e., with any eventual prefixes
72 removed and file name transformations applied. The option is useful,
73 for example, while comparing `tar cv' and `tar tv' outputs.
74
75 ** New incremental snapshot file format keeps information about file names
76 as well as that about directories.
77
78 \f
79 version 1.15.90 - Sergey Poznyakoff, 2006-02-19
80
81 * New features
82
83 ** Any number of -T (--files-from) options may be used in the command line.
84 The file specified with -T may include any valid `tar' options,
85 including another -T option.
86 Compatibility note: older versions of tar would only recognize -C
87 as an option name within the file list file. Now any file whose name
88 starts with - is handled as an option. To insert file names starting with
89 dash, use the --add-file option.
90
91 ** List files containing null-separated file names are detected and processed
92 automatically. It is no longer necessary to give the --null option.
93
94 ** New option --no-unquote disables the unquoting of input file names.
95 This is useful for processing output from `find dir -print0'.
96 An orthogonal option --unquote is provided as well.
97
98 ** New option --test-label tests the archive volume label.
99 If an argument is specified, the label is compared against its value.
100 Tar exits with code 0 if the two strings match, and with code 2 if
101 they do not.
102
103 If no argument is given, the --verbose option is implied. In this case,
104 tar prints the label name if present and exits with code 0.
105
106 ** New option --show-stored-names. When creating an archive in verbose mode,
107 it lists member names as stored in the archive, i.e., with any eventual
108 prefixes removed. The option is useful, for example, while comparing
109 `tar cv' and `tar tv' outputs.
110
111 ** New option --to-command pipes the contents of archive members to the
112 specified command.
113
114 ** New option --atime-preserve=system, which uses the O_NOATIME feature
115 of recent Linux kernels to avoid some problems when preserving file
116 access times.
117
118 ** New option --delay-directory-restore delays restoring modification times
119 and permissions of extracted directories until the end of extraction.
120 This is necessary for restoring from archives with unusual member
121 ordering (in particular, those created with --no-recursion option).
122 This option is implied when restoring from incremental archives.
123
124 ** New option --restrict prohibits use of some potentially harmful tar
125 options. Currently it disables '!' escape in multi-volume name menu.
126
127 ** New options --quoting-style and --quote-chars control the way tar
128 quotes member names on output. The --quoting-style takes an argument
129 specifying the quoting style to use (literal, shell, shell-always,
130 c, escape, locale, clocale). The argument to --quote-chars is a string
131 specifying characters to quote, even if the selected quoting style
132 would not quote them otherwise. The option --no-quote-chars is
133 provided to disable quoting certain characters.
134
135 ** The end-of-volume script (introduced with --info-script option) can
136 get current archive name from the environment variable TAR_ARCHIVE and
137 the volume number from the variable TAR_VOLUME. It can alter the
138 archive name by writing new name to the file descriptor 3.
139
140 ** Better support for full-resolution time stamps. Tar cannot restore
141 time stamps to full nanosecond resolution, though, until the kernel
142 guys get their act together and give us a system call to set file time
143 stamps to nanosecond resolution.
144
145 ** The -v option now prints time stamps only to 1-minute resolution,
146 not full resolution, to avoid using up too many output columns.
147 Nanosecond resolution is now supported, but that would be too much.
148
149 * Bug fixes
150
151 ** Allow non-option arguments to be interspersed with options.
152 ** When extracting or listing archives in old GNU format, tar
153 used to read an extra block of data after a long name header
154 if length of the member name was divisible by block size (512).
155 Consequently, the file pointer was set off and the next member
156 was not processed correctly.
157 ** Previous version created invalid archives when files shrink
158 during reading.
159 ** Compare mode (tar d) hanged when trying to compare file contents.
160 ** Previous versions in certain cases failed to restore directory
161 modification times.
162 ** When creating an archive, do not attempt to store files whose
163 meta-data cannot be stored in the header due to format limitations
164 (for ustar and v7 formats).
165 ** The --version option now also outputs information about copyright,
166 license, and credits. This reverts to the behavior of tar 1.14 and
167 earlier, and conforms to the GNU coding standards. The --license (-L)
168 option introduced in tar 1.15 has been removed, since it's no longer
169 needed.
170
171 \f
172 version 1.15.1 - Sergey Poznyakoff, 2004-12-21
173
174 This version fixes a bug introduced in 1.15 which caused
175 tar to refuse to extract files from standard input.
176
177 \f
178 version 1.15 - Sergey Poznyakoff, 2004-12-20
179
180 * Compressed archives are recognised automatically, it is no longer
181 necessary to specify -Z, -z, or -j options to read them. Thus, you can
182 now run `tar tf archive.tar.gz'.
183
184 * When restoring incremental dumps, --one-file-system option
185 prevents directory hierarchies residing on different devices
186 from being purged.
187
188 With the previous versions of tar it was dangerous to create
189 incremental dumps with --one-file-system option, since they
190 would recursively remove mount points when restoring from the
191 back up. This change fixes the bug.
192
193 * Renamed --strip-path to --strip-components for consistency with
194 the GNU convention.
195
196 * Skipping archive members is sped up if the archive media supports
197 seeks.
198
199 * Restore script starts restoring only if it is given --all (-a) option,
200 or some patterns. This is to prevent accidental restores.
201
202 * `tar --verify' prints a warning if during archive creation some of
203 the file names had their prefixes stripped off.
204
205 * New option --exclude-caches instructs tar to exclude cache directories
206 automatically on archive creation. Cache directories are those
207 containing a standardized tag file, as specified at:
208
209 http://www.brynosaurus.com/cachedir/spec.html
210
211 * New configure option --with-rmt allows to specify full path name to
212 the `rmt' utility. This supersedes DEFAULT_RMT_COMMAND variable
213 introduced in version 1.14
214
215 * New configure variable DEFAULT_RMT_DIR allows to specify the directory
216 where to install `rmt' utility. This is necessary since modifying
217 --libexecdir as was suggested for version 1.14 produced a side effect: it
218 also modified installation prefix for backup scripts (if
219 --enable-backup-scripts was given).
220
221 * Bug fixes:
222 ** Fixed flow in recognizing files to be included in incremental dumps.
223 ** Correctly recognize sparse archive members when used with -T option.
224 ** GNU multivolume headers cannot store filenames longer than 100 characters.
225 Do not allow multivolume archives to begin with such filenames.
226 ** If a member with link count > 2 was stored in the archive twice,
227 previous versions of tar were not able to extract it, since they
228 were trying to link the file to itself, which always failed and
229 lead to removing the already extracted copy. Preserve the first
230 extracted copy in such cases.
231 ** Restore script was passing improper argument to tar --listed option (which
232 didn't affect the functionality, but was logically incorrect).
233 ** Fixed verification of created archives.
234 ** Fixed unquoting of file names containing backslash escapes (previous
235 versions failed to recognize \a and \v).
236 ** When attempting to delete a non-existing member from the archive, previous
237 versions of tar used to overwrite last archive block with zeroes.
238
239 \f
240 version 1.14 - Sergey Poznyakoff, 2004-05-11
241
242 * Added support for POSIX.1-2001 and ustar archive formats.
243 * New option --format allows to select the output archive format
244 * The default output format can be selected at configuration time
245 by presetting the environment variable DEFAULT_ARCHIVE_FORMAT.
246 Allowed values are GNU, V7, OLDGNU and POSIX.
247 * New option --strip-path allows to cut off a given number of
248 path elements from the name of the file being extracted.
249
250 * New options --index-file, --no-overwrite-dir. The --overwrite-dir
251 option is now the default; use --no-overwrite-dir if you prefer
252 the previous default behavior.
253
254 * The semantics of -o option is changed. When extracting, it
255 does the same as --no-same-owner GNU tar option. This is compatible
256 with UNIX98 tar. Otherwise, its effect is the same as that of
257 --old-archive option. This latter is deprecated and will be removed
258 in future.
259
260 * New option --check-links prints a message if not all links are dumped
261 for a file being archived. This corresponds to the UNIX98 -l option.
262 The current semantics of the -l option is retained for compatibility
263 with previous releases, however such usage is strongly deprecated as
264 the option will change to its UNIX98 semantics in the future releases.
265
266 * New option --occurrence[=N] can be used in conjunction with one of
267 the subcommands --delete, --diff, --extract or --list when a list of
268 files is given either on the command line or via -T option. This
269 option instructs tar to process only the Nth occurrence of each named
270 file. N defaults to 1, so `tar -x -f archive --occurrence filename'
271 extracts the first occurrence of `filename' from `archive'
272 and terminates without scanning to the end of the archive.
273
274 * New option --pax-option allows to control the handling of POSIX
275 keywords in `pax' extended headers. It is equivalent to `pax'
276 -o option.
277
278 * --incremental and --listed-incremental options work correctly on
279 individual files, as well as on directories.
280
281 * New scripts: backup (replaces old level-0 and level-1) and restore.
282 The scripts are compiled and installed if --enable-backup-scripts
283 option is given to configure.
284
285 * By default tar searches "rmt" utility in "$prefix/libexec/rmt",
286 which is consistent with the location where the version of "rmt"
287 included in the package is installed. Previous versions of tar
288 used "/etc/rmt". To install "rmt" to its traditional location,
289 run configure with option --libexecdir=/etc. Otherwise, if you
290 already have rmt installed and wish to use it, instead of the
291 shipped in version, set the variable DEFAULT_RMT_COMMAND to
292 the full path name of the utility, e.g., ./configure
293 DEFAULT_RMT_COMMAND=/etc/rmt.
294
295 Notice also that the full path name of the "rmt" utility to
296 use can be set at runtime, by giving option --rmt-command to
297 tar.
298
299 * Removed obsolete command line options:
300 ** --absolute-paths superseded by --absolute-names
301 ** --block-compress is not needed any longer
302 ** --block-size superseded by --blocking-factor
303 ** --modification-time superseded by --touch
304 ** --read-full-blocks superseded by --read-full-records
305 ** --record-number superseded by --block-number
306 ** --version-control superseded by --backup
307
308 * New message translations fi (Finnish), gl (Galician), hr (Croatian),
309 hu (Hungarian), ms (Malaysian), nb (Norwegian), ro (Romanian), sk
310 (Slovak), zh_CN (Chinese simplified), zh_TW (Chinese traditional).
311 The code 'no' for Norwegian (Bokmål) has been withdrawn; use 'nb' instead.
312
313 * Bug fixes.
314
315 \f
316 version 1.13.25 - Paul Eggert, 2001-09-26
317
318 * Bug fixes.
319
320 \f
321 version 1.13.24 - Paul Eggert, 2001-09-22
322
323 * New option --overwrite-dir.
324 * Fixes for buffer overrun, porting, and copyright notice problems.
325 * The message translations for Korean are available again.
326
327 \f
328 version 1.13.23 - Paul Eggert, 2001-09-13
329
330 * Bug, porting, and copyright notice fixes.
331
332 \f
333 version 1.13.22 - Paul Eggert, 2001-08-29
334
335 * Bug fixes.
336
337 \f
338 version 1.13.21 - Paul Eggert, 2001-08-28
339
340 * Porting and copyright notice fixes.
341
342 \f
343 version 1.13.20 - Paul Eggert, 2001-08-27
344
345 * Some bugs were fixed:
346 - security problems
347 - hard links to symbolic links
348
349 * New option --recursion (the default) that is the inverse of --no-recursion.
350
351 * New options --anchored, --ignore-case, --wildcards,
352 --wildcards-match-slash, and their negations (e.g., --no-anchored).
353 Along with --recursion and --no-recursion, these options control how
354 exclude patterns are interpreted.
355
356 * The default interpretation of exclude patterns is now --no-anchored
357 --no-ignore-case --recursion --wildcards --wildcards-match-slash.
358 This is a quiet change to the semantics of --exclude. The previous
359 semantics were a failed attempt at backward compatibility but it
360 became clear that the semantics were puzzling and did not satisfy
361 everybody. Rather than continue to try to revive that dead horse we
362 thought it better to substitute cleaner semantics, with options so
363 that you can change the behavior more to your liking.
364
365 * New message translations for Indonesian and Turkish.
366 The translation for Korean has been withdrawn due to encoding errors.
367 It will be reissued once those are fixed.
368
369 \f
370 version 1.13.19 - Paul Eggert, 2001-01-13
371
372 * The -I option has been withdrawn, as it was buggy and confusing.
373 Eventually it is planned to be reintroduced, with the same meaning as -T.
374
375 * With an option like -N DATE, if DATE starts with "/" or ".", it is taken
376 to be a file name; the last-modified time of that file is used as the date.
377
378 \f
379 version 1.13.18 - Paul Eggert, 2000-10-29
380
381 * Some security problems have been fixed. `tar -x' now modifies only
382 files under the working directory, unless you also specify an unsafe
383 option like --absolute-names or --overwrite.
384
385 * The short name of the --bzip option has been changed to -j,
386 and -I is now an alias for -T, for compatibility with Solaris tar.
387
388 * The manual is now distributed under the GNU Free Documentation License.
389
390 * The new environment variable TAR_OPTIONS holds default command-line options.
391
392 * The --no-recursion option now affects extraction too.
393
394 * The wording in some diagnostics has been changed slightly.
395
396 * Snapshot files now record whether each file was accessed via NFS.
397 The new file format is upward- and downward-compatible with the old.
398
399 * New language supported: da.
400
401 * Compilation by traditional (K&R) C compilers is no longer supported.
402 If you still use such a compiler, please use GCC instead.
403
404 * This version of tar works best with GNU gzip test version 1.3 or later.
405 Please see <ftp://alpha.gnu.org/gnu/gzip/>.
406
407 * `tar --delete -f -' now works again.
408
409 \f
410 version 1.13.17 - Paul Eggert, 2000-01-07.
411
412 * `tar --delete -f -' is no longer allowed; it was too buggy.
413 * Diagnostic messages have been made more regular and consistent.
414
415 \f
416 version 1.13.16 - Paul Eggert, 1999-12-13.
417
418 * By default, tar now refuses to overwrite an existing file when
419 extracting files from an archive; instead, it removes the file
420 before extracting it. If the existing file is a symbolic link, the
421 link is removed and not the pointed-to file. There is one
422 exception: existing nonempty directories are not removed, nor are
423 their ownerships or permissions extracted. This fixes some
424 longstanding security problems.
425
426 The new --overwrite option enables the old default behavior.
427
428 For regular files, tar implements this change by using the O_EXCL
429 option of `open' to ensure that it creates the file; if this fails, it
430 removes the file and tries again. This is similar to the behavior of
431 the --unlink-first option, but it is faster in the common case of
432 extracting a new directory.
433
434 * By default, tar now ignores file names containing a component of `..'
435 when extracting, and warns about such file names when creating an archive.
436 To enable the old behavior, use the -P or --absolute-names option.
437
438 * Tar now handles file names with multibyte encodings (e.g., UTF-8, Shift-JIS)
439 correctly. It relies on the mbrtowc function to handle multibyte characters.
440
441 * The file generated by -g or --listed-incremental now uses a format
442 that is independent of locale, so that users need not worry about
443 locale when restoring a backup. This is needed for proper support
444 of multibyte characters. Old-format files can still be read, and
445 older versions of GNU tar can read new-format files, unless member
446 names have multibyte chars.
447
448 * Many diagnostics have been changed slightly, so that file names are
449 now output unambiguously. File names in diagnostics now are either
450 `quoted like this' (in the default C locale) or are followed by
451 colon, newline, or space, depending on context. Unprintable
452 characters are escaped with a C-like backslash conventions.
453 Terminating characters (e.g., close-quote, colon, newline)
454 are also escaped as needed.
455
456 * tar now ignores socket files when creating an archive.
457 Previously tar archived sockets as fifos, which caused problems.
458
459 \f
460 version 1.13.15 - Paul Eggert, 1999-12-03.
461
462 * If a file's ctime changes when being archived, report an error.
463 Previously tar looked at mtime, which missed some errors.
464
465 \f
466 version 1.13.14 - Paul Eggert, 1999-11-07.
467
468 * New translations ja, pt_BR.
469 * New options --help and --version for rmt.
470 * Ignore Solaris door files when creating an archive.
471
472 \f
473 version 1.13.13 - Paul Eggert, 1999-10-11.
474
475 * Invalid headers in tar files now elicit errors, not just warnings.
476 * `tar --version' output conforms to the latest GNU coding standards.
477 * If you specify an invalid date, `tar' now substitutes (time_t) -1.
478 * `configure --with-dmalloc' is no longer available.
479
480 \f
481 version 1.13.12 - Paul Eggert, 1999-09-24.
482
483 * `tar' now supports hard links to symbolic links.
484
485 * New options --no-same-owner, --no-same-permissions.
486
487 * --total now also outputs a human-readable size, and a throughput value.
488
489 * `tar' now uses two's-complement base-256 when outputting header
490 values that are out of the range of the standard unsigned base-8
491 format. This affects archive members with negative or huge time
492 stamps or uids, and archive members 8 GB or larger. The new tar
493 archives cannot be read by traditional tar, or by older versions of
494 GNU tar. Use the --old-archive option to revert to the old
495 behavior, which uses unportable representations for negative values,
496 and which rejects large files.
497
498 * On 32-bit hosts, `tar' now assumes that an incoming time stamp T in
499 the range 2**31 <= T < 2**32 represents the negative time (T -
500 2**32). This behavior is nonstandard and is not portable to 64-bit
501 time_t hosts, so `tar' issues a warning.
502
503 * `tar' no longer gives up extracting immediately upon discovering
504 that an archive contains garbage at the end. It attempts to extract
505 as many files as possible from the good data before the garbage.
506
507 * A read error now causes a nonzero exit status, not just a warning.
508
509 * Some diagnostics have been reworded for consistency.
510
511 \f
512 version 1.13.11 - Paul Eggert, 1999-08-23.
513
514 * The short name of the --bzip option has been changed to -I,
515 for compatibility with paxutils.
516
517 * -T /dev/null now matches nothing; previously, it matched anything
518 if no explicit operands were given.
519
520 * The `--' option now works the same as with other GNU utilities;
521 it causes later operands to be interpreted as file names, not options,
522 even if they begin with `-'.
523
524 * For the --newer and --after-date options, the table of time zone
525 abbreviations like `EST' has been updated to match current practice.
526 Also, local time abbreviations are now recognized, even if they are
527 not in tar's hardwired table. Remember, though, that you should use
528 numeric UTC offsets like `-0500' instead of abbreviations like
529 `EST', as abbreviations are not standardized and are ambiguous.

532 version 1.13.10 - Paul Eggert, 1999-08-20.
533
534 * `tar' now uses signed base-64 when outputting header values that are
535 out of the range of the standard unsigned base-8 format. [This
536 change was superseded in 1.13.12, described above.]
537
538 \f
539 version 1.13.9 - Paul Eggert, 1999-08-18.
540
541 * `tar' now writes two zero blocks at end-of-archive instead of just one.
542 POSIX.1 requires this, and some other `tar' implementations check for it.
543
544 * `tar' no longer silently accepts a block containing nonzero checksum bytes
545 as a zero block.
546
547 * `tar' now reads buggy tar files that have a null byte at the start of a
548 numeric header field.
549
550 \f
551 version 1.13.8 - Paul Eggert, 1999-08-16.
552
553 * For compatibility with traditional `tar', intermediate directories
554 created automatically by root are no longer given the uid and gid of
555 the original file or directory.
556
557 \f
558 version 1.13.7 - Paul Eggert, 1999-08-14.
559
560 * --listed-incremental and --newer are now incompatible options.
561
562 * When creating an archive, leading `./' is no longer stripped,
563 to match traditional tar's behavior (and simplify the documentation).
564
565 * --diff without --absolute-names no longer falls back on absolute names.
566
567 \f
568 version 1.13.6 - Paul Eggert, 1999-08-11.
569
570 * An --exclude pattern containing / now excludes a file only if it matches an
571 initial prefix of the file name; a pattern without / continues to
572 exclude a file if it matches any file name component.
573
574 * The protocol for talking to rmt has been extended slightly.
575 Open flags are now communicated in symbolic format as well as numeric.
576 The symbolic format (e.g., "O_WRONLY|O_CREAT|O_TRUNC") is for portability
577 when rmt is operating on a different operating system from tar.
578 The numeric format is retained, and rmt uses it if symbolic format is absent,
579 for backward compatibility with older versions of tar and rmt.
580
581 * When writing GNU tar format headers, tar now uses signed base-64
582 for values that cannot be represented in unsigned octal.
583 This supports larger files (2**66 - 1 bytes instead of 2**33 - 1 bytes),
584 larger uids, negative time stamps, etc.
585
586 * When extracting files with unknown ownership, tar now looks up the
587 uid and gid "nobody" on hosts whose headers do not define UID_NOBODY
588 and GID_NOBODY, and falls back on uid/gid -2 if there is no "nobody".
589
590 * tar -t --numeric-owner now prints numeric uids and gids, not symbolic.
591
592 * New option -y or --bzip2 for bzip2 compression, by popular request.
593
594 \f
595 version 1.13.5 - Paul Eggert, 1999-07-20.
596
597 * Do the delayed updates of file metadata even after a fatal error.
598
599 \f
600 version 1.13.4 - Paul Eggert, 1999-07-20.
601
602 * Do not chmod unless we are root or the -p option was given;
603 this matches historical practice.
604
605 \f
606 version 1.13.3 - Paul Eggert, 1999-07-16.
607
608 * A path name is excluded if any of its file name components matches an
609 excluded pattern, even if the path name was specified on the command line.
610 Also see 1.13.6 for later changes in this area.
611
612 \f
613 version 1.13.2 - Paul Eggert, 1999-07-14.
614
615 * Bug reporting address changed to <bug-tar@gnu.org>.
616
617 \f
618 version 1.13.1 - Paul Eggert, 1999-07-12.
619
620 * Bug fixes only.
621 \f
622 version 1.13 - Paul Eggert, 1999-07-08.
623
624 * Support for large files, e.g., files larger than 2 GB on many 32-bit hosts.
625 Also, support for larger uids, device ids, etc.
626 * Many bug fixes and porting fixes.
627 * This release is only for fixes. A more ambitious test release,
628 with new features, is available as part of the paxutils. Please see:
629 ftp://alpha.gnu.org/gnu/paxutils/
630 The fixes in this release are intended to be merged with paxutils
631 at some point, but they haven't been merged yet.
632 * An interim GNU tar alpha had new --bzip2 and --ending-file options,
633 but they have been removed to maintain compatibility with paxutils.
634 Please try --use=bzip2 instead of --bzip2.
635 \f
636 Version 1.12 - François Pinard, 1997-04.
637
638 Sensitive matters
639 * Use shell globbing patterns for --label, instead of regular expressions.
640 * Do not quote anymore internally over the quoting done by the shell.
641
642 Output for humans
643 * Offer internationalization capabilities of most recent GNU gettext.
644 * Messages available in many more languages, thanks to all translators!
645 * Usage of ISO 8601 dates in listings, instead of local American dates.
646 * More normalization and cleanup in error messages.
647
648 Creation
649 * For helping using tar with find, offer a --no-recursion option.
650 * Implement --numeric-owner for ignoring symbolic names at create time.
651 * New --owner, --group --mode options, still preliminary.
652 * Recognize creating an archive on /dev/null, so Amanda works faster.
653 * Object to the creation of an empty archive (like in `tar cf FILE').
654 * Barely start implementing --posix and POSIXLY_CORRECT.
655
656 Extraction
657 * Make a better job at restoring file and directory attributes.
658 * Automatically attempt deleting existing files when in the way.
659 * Option --unlink-first (-U) removes most files prior to extraction.
660 * Option --recursive-unlink removes non-empty directories when in the way.
661 * Option --numeric-owner ignores owner/group names, it uses UID/GID instead.
662 * Use global umask when creating missing intermediate directories.
663 * When symlinks are not available, extract symbolic links as hard links.
664 * Diagnose extraction of contiguous files as regular files.
665 * New --backup, --suffix and --version-control options.
666
667 Various changes
668 * Better support of huge archives with --tape-length and --totals.
669 * Rename option --read-full-blocks (-B) to --read-full-records (-B).
670 * Rename option --block-size (-b) to --blocking-factor (-b).
671 * Rename option --record-number (-R) to --block-number (-R).
672 * With --block-number (-R), report null blocks and end of file.
673 * Implement --record-size for introducing a size in bytes.
674 * Delete --block-compress option and rather decide it automatically.
675 * Rename option --modification-time to --touch.
676
677 Many bugs are squashed, while others still run free.
678 \f
679 Version 1.11.8 - François Pinard, 1995-06.
680
681 * Messages available in French, German, Portuguese and Swedish.
682 * The distribution provides a rudimentary Texinfo manual.
683 * The device defaults to stdin/stdout, unless overridden by the installer.
684 * Option --sparse (-S) should work on more systems.
685 * Option --rsh-command may select an alternative remote shell program.
686
687 Most changes are internal, and should yield better portability.
688 \f
689 Version 1.11.2 - Michael Bushnell, 1993-03.
690
691 * Changes in backup scripts: cleaned up considerably; notices error
692 conditions better over rsh; DUMP_REMIND_SCRIPT is now an option in
693 backup-specs; new file dump-remind is an example of a
694 DUMP_REMIND_SCRIPT.
695
696 * Superfluous "Reading dirname" was a bug; fixed.
697
698 * Incompatibility problems with a bug on Solaris are fixed.
699
700 * New option --gzip (aliases are --ungzip and -z); calls gzip instead
701 of compress. Also, --use-compress-program lets you specify any
702 compress program. --compress-block is renamed --block-compress and
703 now requires one of the three compression options to be specified.
704
705 * Several error messages are cleaned up.
706
707 * Directory owners are now set properly when running as root.
708
709 * Provide DUMP_REMIND_SCRIPT in backup-specs as a possible option
710 for --info-script.
711
712 * Behave better with broken rmt servers.
713
714 * Dump scripts no longer use --atime-preserve; this causes a nasty probem.
715
716 * Several Makefile cleanups.
717 \f
718 Version 1.11.1 - Michael Bushnell, 1992-09.
719
720 * Many bug fixes.
721 \f
722 Version 1.11 - Michael Bushnell, 1992-09.
723 Version 1.10.16 - 1992-07.
724 Version 1.10.15 - 1992-06.
725 Version 1.10.14 - 1992-05.
726 Version 1.10.13 - 1992-01.
727
728 * Many bug fixes.
729
730 * Now uses GNU standard configure, generated by Autoconf.
731
732 * Long options now use `--'; use of `+' is deprecated and support
733 for it will eventually be removed.
734
735 * New option --null causes filenames read by -T to be
736 null-terminated, and causes -C to be ignored.
737
738 * New option --remove-files deletes files (but not directories)
739 after they are added to the archive.
740
741 * New option --ignore-failed-read prevents read-errors from affecting
742 the exit status.
743
744 * New option --checkpoint prints occasional messages as the tape
745 is being read or written.
746
747 * New option --show-omitted-dirs prints the names of directories
748 omitted from the archive.
749
750 * Some tape drives which use a non-standard method of indicating
751 end-of-tape now work correctly with multi-tape archives.
752
753 * --volno-file: Read the volume number used in prompting the user
754 (but not in recording volume ID's on the archive) from a file.
755
756 * When using --multi-volume, you can now give multiple -f arguments;
757 the various tape drives will get used in sequence and then wrap
758 around to the beginning.
759
760 * Remote archive names no longer have to be in /dev: any file with a
761 `:' is interpreted as remote. If new option --force-local is given,
762 then even archive files with a `:' are considered local.
763
764 * New option --atime-preserve restores (if possible) atimes to
765 their original values after dumping the file.
766
767 * No longer does tar confusingly dump "." when you don't tell it
768 what to dump.
769
770 * When extracting directories, tar now correctly restores their
771 modification and access times.
772
773 * Longnames support is redone differently--long name info directly
774 precedes the long-named file or link in the archive, so you no
775 longer have to wait for the extract to hit the end of the tape for
776 long names to work.
777 \f
778 Version 1.10 - Michael Bushnell, 1991-07.
779
780 * Filename to -G is optional. -C works right. Names +newer and
781 +newer-mtime work right.
782
783 * -g is now +incremental, -G is now +listed-incremental.
784
785 * Sparse files now work correctly.
786
787 * +volume is now called +label.
788
789 * +exclude now takes a filename argument, and +exclude-from does
790 what +exclude used to do.
791
792 * Exit status is now correct.
793
794 * +totals keeps track of total I/O and prints it when tar exits.
795
796 * When using +label with +extract, the label is now a regexp.
797
798 * New option +tape-length (-L) does multi-volume handling like BSD
799 dump: you tell tar how big the tape is and it will prompt at that
800 point instead of waiting for a write error.
801
802 * New backup scripts level-0 and level-1 which might be useful
803 to people. They use a file "backup-specs" for information, and
804 shouldn't need local modification. These are what we use to do
805 all our backups at the FSF.
