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

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