4 version 1.15.92 - Sergey Poznyakoff, (CVS)
5
6 * New option --mtime allows to set modification times for all archive
7 members during creation.
8
9 * Bug fixes
10 ** Avoid running off file descriptors when using multiple -C options.
11 ** tar --index-file=FILE --file=- sent the archive to FILE, and
12 the listing to stderr.

15 version 1.15.91 - Sergey Poznyakoff, 2006-06-16
16
17 * Incompatible changes
18
19 ** Globbing
20
21 Previous versions of GNU tar assumed shell-style globbing when
22 extracting from or listing an archive. For example:
23
24 tar xf foo.tar '*.c'
25
26 would extract all files whose names end in '.c'. This behavior
27 was not documented and was incompatible with traditional tar
28 implementations. Therefore, starting from this version, GNU tar
29 no longer uses globbing by default. For example, the above invocation
30 is now interpreted as a request to extract from the archive the file
31 named '*.c'.
32
33 To treat member names as globbing patterns, use --wildcards option.
34 If you wish tar to mimic the behavior of versions up to 1.15.90,
35 add --wildcards to the value of the environment variable TAR_OPTIONS.
36
37 The exact way in which tar interprets member names is controlled by the
38 following command line options:
39
40 --wildcards use wildcards
41 --anchored patterns match file name start
42 --ignore-case ignore case
43 --wildcards-match-slash wildcards match `/'
44
45 Each of these options has a '--no-' counterpart that disables its
46 effect (e.g. --no-wildcards).
47
48 These options affect both the interpretation of member names from
49 command line and that of the exclusion patterns (given with --exclude
50 and --exclude-from options). The defaults are:
51
52 1. For member names: --no-wildcards --anchored
53 2. For exclusion patterns: --wildcards --no-anchored --wildcards-match-slash
54
55 The options can appear multiple times in the command line, thereby
56 changing the way command line arguments are interpreted. For example,
57 to use case-insensitive matching in exclude patterns and to revert to
58 case-sensitive matching for the rest of command line, one could write:
59
60 tar xf foo.tar --ignore-case --exclude-from=FILE --no-ignore-case file.name
61
62 ** Short option -l is now an alias of --check-links option, which complies
63 with UNIX98. This ends the transition period started with version 1.14.
64
65 * New features
66
67 ** New option --transform allows to transform file names before storing them
68 in the archive or member names before extracting. The option takes a
69 sed replace expression as its argument. For example,
70
71 tar cf foo.tar --transform 's,^,prefix/,'
72
73 will add 'prefix/' to all file names stored in foo.tar.
74
75 ** --strip-components option works when deleting and comparing. In previous
76 versions it worked only with --extract.
77
78 ** New option --show-transformed-names enables display of transformed file
79 or archive. It generalizes --show-stored-names option, introduced in
80 1.15.90. In particular, when creating an archive in verbose mode, it lists
81 member names as stored in the archive, i.e., with any eventual prefixes
82 removed and file name transformations applied. The option is useful,
83 for example, while comparing `tar cv' and `tar tv' outputs.
84
85 ** New incremental snapshot file format keeps information about file names
86 as well as that about directories.
87
88 ** The --checkpoint option takes an optional argument specifying the number
89 of records between the two successive checkpoints. Optional dot
90 starting the argument intructs tar to print dots instead of textual
91 checkpoints.
92
93 ** The --totals option can be used with any tar operation (previous versions
94 understood it only with --create). If an argument to this option is
95 given, it specifies the signal upon delivery of which the statistics
96 is to be printed. Both forms of this option (with and without
97 argument) can be given to in a single invocation of tar.
98
99 * Bug fixes
100 ** Detect attempts to update compressed archives.
101
102 \f
103 version 1.15.90 - Sergey Poznyakoff, 2006-02-19
104
105 * New features
106
107 ** Any number of -T (--files-from) options may be used in the command line.
108 The file specified with -T may include any valid `tar' options,
109 including another -T option.
110 Compatibility note: older versions of tar would only recognize -C
111 as an option name within the file list file. Now any file whose name
112 starts with - is handled as an option. To insert file names starting with
113 dash, use the --add-file option.
114
115 ** List files containing null-separated file names are detected and processed
116 automatically. It is no longer necessary to give the --null option.
117
118 ** New option --no-unquote disables the unquoting of input file names.
119 This is useful for processing output from `find dir -print0'.
120 An orthogonal option --unquote is provided as well.
121
122 ** New option --test-label tests the archive volume label.
123 If an argument is specified, the label is compared against its value.
124 Tar exits with code 0 if the two strings match, and with code 2 if
125 they do not.
126
127 If no argument is given, the --verbose option is implied. In this case,
128 tar prints the label name if present and exits with code 0.
129
130 ** New option --show-stored-names. When creating an archive in verbose mode,
131 it lists member names as stored in the archive, i.e., with any eventual
132 prefixes removed. The option is useful, for example, while comparing
133 `tar cv' and `tar tv' outputs.
134
135 ** New option --to-command pipes the contents of archive members to the
136 specified command.
137
138 ** New option --atime-preserve=system, which uses the O_NOATIME feature
139 of recent Linux kernels to avoid some problems when preserving file
140 access times.
141
142 ** New option --delay-directory-restore delays restoring modification times
143 and permissions of extracted directories until the end of extraction.
144 This is necessary for restoring from archives with unusual member
145 ordering (in particular, those created with --no-recursion option).
146 This option is implied when restoring from incremental archives.
147
148 ** New option --restrict prohibits use of some potentially harmful tar
149 options. Currently it disables '!' escape in multi-volume name menu.
150
151 ** New options --quoting-style and --quote-chars control the way tar
152 quotes member names on output. The --quoting-style takes an argument
153 specifying the quoting style to use (literal, shell, shell-always,
154 c, escape, locale, clocale). The argument to --quote-chars is a string
155 specifying characters to quote, even if the selected quoting style
156 would not quote them otherwise. The option --no-quote-chars is
157 provided to disable quoting certain characters.
158
159 ** The end-of-volume script (introduced with --info-script option) can
160 get current archive name from the environment variable TAR_ARCHIVE and
161 the volume number from the variable TAR_VOLUME. It can alter the
162 archive name by writing new name to the file descriptor 3.
163
164 ** Better support for full-resolution time stamps. Tar cannot restore
165 time stamps to full nanosecond resolution, though, until the kernel
166 guys get their act together and give us a system call to set file time
167 stamps to nanosecond resolution.
168
169 ** The -v option now prints time stamps only to 1-minute resolution,
170 not full resolution, to avoid using up too many output columns.
171 Nanosecond resolution is now supported, but that would be too much.
172
173 * Bug fixes
174
175 ** Allow non-option arguments to be interspersed with options.
176 ** When extracting or listing archives in old GNU format, tar
177 used to read an extra block of data after a long name header
178 if length of the member name was divisible by block size (512).
179 Consequently, the file pointer was set off and the next member
180 was not processed correctly.
181 ** Previous version created invalid archives when files shrink
182 during reading.
183 ** Compare mode (tar d) hanged when trying to compare file contents.
184 ** Previous versions in certain cases failed to restore directory
185 modification times.
186 ** When creating an archive, do not attempt to store files whose
187 meta-data cannot be stored in the header due to format limitations
188 (for ustar and v7 formats).
189 ** The --version option now also outputs information about copyright,
190 license, and credits. This reverts to the behavior of tar 1.14 and
191 earlier, and conforms to the GNU coding standards. The --license (-L)
192 option introduced in tar 1.15 has been removed, since it's no longer
193 needed.
194
195 \f
196 version 1.15.1 - Sergey Poznyakoff, 2004-12-21
197
198 This version fixes a bug introduced in 1.15 which caused
199 tar to refuse to extract files from standard input.
200
201 \f
202 version 1.15 - Sergey Poznyakoff, 2004-12-20
203
204 * Compressed archives are recognised automatically, it is no longer
205 necessary to specify -Z, -z, or -j options to read them. Thus, you can
206 now run `tar tf archive.tar.gz'.
207
208 * When restoring incremental dumps, --one-file-system option
209 prevents directory hierarchies residing on different devices
210 from being purged.
211
212 With the previous versions of tar it was dangerous to create
213 incremental dumps with --one-file-system option, since they
214 would recursively remove mount points when restoring from the
215 back up. This change fixes the bug.
216
217 * Renamed --strip-path to --strip-components for consistency with
218 the GNU convention.
219
220 * Skipping archive members is sped up if the archive media supports
221 seeks.
222
223 * Restore script starts restoring only if it is given --all (-a) option,
224 or some patterns. This is to prevent accidental restores.
225
226 * `tar --verify' prints a warning if during archive creation some of
227 the file names had their prefixes stripped off.
228
229 * New option --exclude-caches instructs tar to exclude cache directories
230 automatically on archive creation. Cache directories are those
231 containing a standardized tag file, as specified at:
232
233 http://www.brynosaurus.com/cachedir/spec.html
234
235 * New configure option --with-rmt allows to specify full path name to
236 the `rmt' utility. This supersedes DEFAULT_RMT_COMMAND variable
237 introduced in version 1.14
238
239 * New configure variable DEFAULT_RMT_DIR allows to specify the directory
240 where to install `rmt' utility. This is necessary since modifying
241 --libexecdir as was suggested for version 1.14 produced a side effect: it
242 also modified installation prefix for backup scripts (if
243 --enable-backup-scripts was given).
244
245 * Bug fixes:
246 ** Fixed flow in recognizing files to be included in incremental dumps.
247 ** Correctly recognize sparse archive members when used with -T option.
248 ** GNU multivolume headers cannot store filenames longer than 100 characters.
249 Do not allow multivolume archives to begin with such filenames.
250 ** If a member with link count > 2 was stored in the archive twice,
251 previous versions of tar were not able to extract it, since they
252 were trying to link the file to itself, which always failed and
253 lead to removing the already extracted copy. Preserve the first
254 extracted copy in such cases.
255 ** Restore script was passing improper argument to tar --listed option (which
256 didn't affect the functionality, but was logically incorrect).
257 ** Fixed verification of created archives.
258 ** Fixed unquoting of file names containing backslash escapes (previous
259 versions failed to recognize \a and \v).
260 ** When attempting to delete a non-existing member from the archive, previous
261 versions of tar used to overwrite last archive block with zeroes.
262
263 \f
264 version 1.14 - Sergey Poznyakoff, 2004-05-11
265
266 * Added support for POSIX.1-2001 and ustar archive formats.
267 * New option --format allows to select the output archive format
268 * The default output format can be selected at configuration time
269 by presetting the environment variable DEFAULT_ARCHIVE_FORMAT.
270 Allowed values are GNU, V7, OLDGNU and POSIX.
271 * New option --strip-path allows to cut off a given number of
272 path elements from the name of the file being extracted.
273
274 * New options --index-file, --no-overwrite-dir. The --overwrite-dir
275 option is now the default; use --no-overwrite-dir if you prefer
276 the previous default behavior.
277
278 * The semantics of -o option is changed. When extracting, it
279 does the same as --no-same-owner GNU tar option. This is compatible
280 with UNIX98 tar. Otherwise, its effect is the same as that of
281 --old-archive option. This latter is deprecated and will be removed
282 in future.
283
284 * New option --check-links prints a message if not all links are dumped
285 for a file being archived. This corresponds to the UNIX98 -l option.
286 The current semantics of the -l option is retained for compatibility
287 with previous releases, however such usage is strongly deprecated as
288 the option will change to its UNIX98 semantics in the future releases.
289
290 * New option --occurrence[=N] can be used in conjunction with one of
291 the subcommands --delete, --diff, --extract or --list when a list of
292 files is given either on the command line or via -T option. This
293 option instructs tar to process only the Nth occurrence of each named
294 file. N defaults to 1, so `tar -x -f archive --occurrence filename'
295 extracts the first occurrence of `filename' from `archive'
296 and terminates without scanning to the end of the archive.
297
298 * New option --pax-option allows to control the handling of POSIX
299 keywords in `pax' extended headers. It is equivalent to `pax'
300 -o option.
301
302 * --incremental and --listed-incremental options work correctly on
303 individual files, as well as on directories.
304
305 * New scripts: backup (replaces old level-0 and level-1) and restore.
306 The scripts are compiled and installed if --enable-backup-scripts
307 option is given to configure.
308
309 * By default tar searches "rmt" utility in "$prefix/libexec/rmt",
310 which is consistent with the location where the version of "rmt"
311 included in the package is installed. Previous versions of tar
312 used "/etc/rmt". To install "rmt" to its traditional location,
313 run configure with option --libexecdir=/etc. Otherwise, if you
314 already have rmt installed and wish to use it, instead of the
315 shipped in version, set the variable DEFAULT_RMT_COMMAND to
316 the full path name of the utility, e.g., ./configure
317 DEFAULT_RMT_COMMAND=/etc/rmt.
318
319 Notice also that the full path name of the "rmt" utility to
320 use can be set at runtime, by giving option --rmt-command to
321 tar.
322
323 * Removed obsolete command line options:
324 ** --absolute-paths superseded by --absolute-names
325 ** --block-compress is not needed any longer
326 ** --block-size superseded by --blocking-factor
327 ** --modification-time superseded by --touch
328 ** --read-full-blocks superseded by --read-full-records
329 ** --record-number superseded by --block-number
330 ** --version-control superseded by --backup
331
332 * New message translations fi (Finnish), gl (Galician), hr (Croatian),
333 hu (Hungarian), ms (Malaysian), nb (Norwegian), ro (Romanian), sk
334 (Slovak), zh_CN (Chinese simplified), zh_TW (Chinese traditional).
335 The code 'no' for Norwegian (Bokmål) has been withdrawn; use 'nb' instead.
336
337 * Bug fixes.
338
339 \f
340 version 1.13.25 - Paul Eggert, 2001-09-26
341
342 * Bug fixes.
343
344 \f
345 version 1.13.24 - Paul Eggert, 2001-09-22
346
347 * New option --overwrite-dir.
348 * Fixes for buffer overrun, porting, and copyright notice problems.
349 * The message translations for Korean are available again.
350
351 \f
352 version 1.13.23 - Paul Eggert, 2001-09-13
353
354 * Bug, porting, and copyright notice fixes.
355
356 \f
357 version 1.13.22 - Paul Eggert, 2001-08-29
358
359 * Bug fixes.
360
361 \f
362 version 1.13.21 - Paul Eggert, 2001-08-28
363
364 * Porting and copyright notice fixes.
365
366 \f
367 version 1.13.20 - Paul Eggert, 2001-08-27
368
369 * Some bugs were fixed:
370 - security problems
371 - hard links to symbolic links
372
373 * New option --recursion (the default) that is the inverse of --no-recursion.
374
375 * New options --anchored, --ignore-case, --wildcards,
376 --wildcards-match-slash, and their negations (e.g., --no-anchored).
377 Along with --recursion and --no-recursion, these options control how
378 exclude patterns are interpreted.
379
380 * The default interpretation of exclude patterns is now --no-anchored
381 --no-ignore-case --recursion --wildcards --wildcards-match-slash.
382 This is a quiet change to the semantics of --exclude. The previous
383 semantics were a failed attempt at backward compatibility but it
384 became clear that the semantics were puzzling and did not satisfy
385 everybody. Rather than continue to try to revive that dead horse we
386 thought it better to substitute cleaner semantics, with options so
387 that you can change the behavior more to your liking.
388
389 * New message translations for Indonesian and Turkish.
390 The translation for Korean has been withdrawn due to encoding errors.
391 It will be reissued once those are fixed.
392
393 \f
394 version 1.13.19 - Paul Eggert, 2001-01-13
395
396 * The -I option has been withdrawn, as it was buggy and confusing.
397 Eventually it is planned to be reintroduced, with the same meaning as -T.
398
399 * With an option like -N DATE, if DATE starts with "/" or ".", it is taken
400 to be a file name; the last-modified time of that file is used as the date.
401
402 \f
403 version 1.13.18 - Paul Eggert, 2000-10-29
404
405 * Some security problems have been fixed. `tar -x' now modifies only
406 files under the working directory, unless you also specify an unsafe
407 option like --absolute-names or --overwrite.
408
409 * The short name of the --bzip option has been changed to -j,
410 and -I is now an alias for -T, for compatibility with Solaris tar.
411
412 * The manual is now distributed under the GNU Free Documentation License.
413
414 * The new environment variable TAR_OPTIONS holds default command-line options.
415
416 * The --no-recursion option now affects extraction too.
417
418 * The wording in some diagnostics has been changed slightly.
419
420 * Snapshot files now record whether each file was accessed via NFS.
421 The new file format is upward- and downward-compatible with the old.
422
423 * New language supported: da.
424
425 * Compilation by traditional (K&R) C compilers is no longer supported.
426 If you still use such a compiler, please use GCC instead.
427
428 * This version of tar works best with GNU gzip test version 1.3 or later.
429 Please see <ftp://alpha.gnu.org/gnu/gzip/>.
430
431 * `tar --delete -f -' now works again.
432
433 \f
434 version 1.13.17 - Paul Eggert, 2000-01-07.
435
436 * `tar --delete -f -' is no longer allowed; it was too buggy.
437 * Diagnostic messages have been made more regular and consistent.
438
439 \f
440 version 1.13.16 - Paul Eggert, 1999-12-13.
441
442 * By default, tar now refuses to overwrite an existing file when
443 extracting files from an archive; instead, it removes the file
444 before extracting it. If the existing file is a symbolic link, the
445 link is removed and not the pointed-to file. There is one
446 exception: existing nonempty directories are not removed, nor are
447 their ownerships or permissions extracted. This fixes some
448 longstanding security problems.
449
450 The new --overwrite option enables the old default behavior.
451
452 For regular files, tar implements this change by using the O_EXCL
453 option of `open' to ensure that it creates the file; if this fails, it
454 removes the file and tries again. This is similar to the behavior of
455 the --unlink-first option, but it is faster in the common case of
456 extracting a new directory.
457
458 * By default, tar now ignores file names containing a component of `..'
459 when extracting, and warns about such file names when creating an archive.
460 To enable the old behavior, use the -P or --absolute-names option.
461
462 * Tar now handles file names with multibyte encodings (e.g., UTF-8, Shift-JIS)
463 correctly. It relies on the mbrtowc function to handle multibyte characters.
464
465 * The file generated by -g or --listed-incremental now uses a format
466 that is independent of locale, so that users need not worry about
467 locale when restoring a backup. This is needed for proper support
468 of multibyte characters. Old-format files can still be read, and
469 older versions of GNU tar can read new-format files, unless member
470 names have multibyte chars.
471
472 * Many diagnostics have been changed slightly, so that file names are
473 now output unambiguously. File names in diagnostics now are either
474 `quoted like this' (in the default C locale) or are followed by
475 colon, newline, or space, depending on context. Unprintable
476 characters are escaped with a C-like backslash conventions.
477 Terminating characters (e.g., close-quote, colon, newline)
478 are also escaped as needed.
479
480 * tar now ignores socket files when creating an archive.
481 Previously tar archived sockets as fifos, which caused problems.
482
483 \f
484 version 1.13.15 - Paul Eggert, 1999-12-03.
485
486 * If a file's ctime changes when being archived, report an error.
487 Previously tar looked at mtime, which missed some errors.
488
489 \f
490 version 1.13.14 - Paul Eggert, 1999-11-07.
491
492 * New translations ja, pt_BR.
493 * New options --help and --version for rmt.
494 * Ignore Solaris door files when creating an archive.
495
496 \f
497 version 1.13.13 - Paul Eggert, 1999-10-11.
498
499 * Invalid headers in tar files now elicit errors, not just warnings.
500 * `tar --version' output conforms to the latest GNU coding standards.
501 * If you specify an invalid date, `tar' now substitutes (time_t) -1.
502 * `configure --with-dmalloc' is no longer available.
503
504 \f
505 version 1.13.12 - Paul Eggert, 1999-09-24.
506
507 * `tar' now supports hard links to symbolic links.
508
509 * New options --no-same-owner, --no-same-permissions.
510
511 * --total now also outputs a human-readable size, and a throughput value.
512
513 * `tar' now uses two's-complement base-256 when outputting header
514 values that are out of the range of the standard unsigned base-8
515 format. This affects archive members with negative or huge time
516 stamps or uids, and archive members 8 GB or larger. The new tar
517 archives cannot be read by traditional tar, or by older versions of
518 GNU tar. Use the --old-archive option to revert to the old
519 behavior, which uses unportable representations for negative values,
520 and which rejects large files.
521
522 * On 32-bit hosts, `tar' now assumes that an incoming time stamp T in
523 the range 2**31 <= T < 2**32 represents the negative time (T -
524 2**32). This behavior is nonstandard and is not portable to 64-bit
525 time_t hosts, so `tar' issues a warning.
526
527 * `tar' no longer gives up extracting immediately upon discovering
528 that an archive contains garbage at the end. It attempts to extract
529 as many files as possible from the good data before the garbage.
530
531 * A read error now causes a nonzero exit status, not just a warning.
532
533 * Some diagnostics have been reworded for consistency.
534
535 \f
536 version 1.13.11 - Paul Eggert, 1999-08-23.
537
538 * The short name of the --bzip option has been changed to -I,
539 for compatibility with paxutils.
540
541 * -T /dev/null now matches nothing; previously, it matched anything
542 if no explicit operands were given.
543
544 * The `--' option now works the same as with other GNU utilities;
545 it causes later operands to be interpreted as file names, not options,
546 even if they begin with `-'.
547
548 * For the --newer and --after-date options, the table of time zone
549 abbreviations like `EST' has been updated to match current practice.
550 Also, local time abbreviations are now recognized, even if they are
551 not in tar's hardwired table. Remember, though, that you should use
552 numeric UTC offsets like `-0500' instead of abbreviations like
553 `EST', as abbreviations are not standardized and are ambiguous.
554
555 \f
556 version 1.13.10 - Paul Eggert, 1999-08-20.
557
558 * `tar' now uses signed base-64 when outputting header values that are
559 out of the range of the standard unsigned base-8 format. [This
560 change was superseded in 1.13.12, described above.]
561
562 \f
563 version 1.13.9 - Paul Eggert, 1999-08-18.
564
565 * `tar' now writes two zero blocks at end-of-archive instead of just one.
566 POSIX.1 requires this, and some other `tar' implementations check for it.
567
568 * `tar' no longer silently accepts a block containing nonzero checksum bytes
569 as a zero block.
570
571 * `tar' now reads buggy tar files that have a null byte at the start of a
572 numeric header field.
573
574 \f
575 version 1.13.8 - Paul Eggert, 1999-08-16.
576
577 * For compatibility with traditional `tar', intermediate directories
578 created automatically by root are no longer given the uid and gid of
579 the original file or directory.
580
581 \f
582 version 1.13.7 - Paul Eggert, 1999-08-14.
583
584 * --listed-incremental and --newer are now incompatible options.
585
586 * When creating an archive, leading `./' is no longer stripped,
587 to match traditional tar's behavior (and simplify the documentation).
588
589 * --diff without --absolute-names no longer falls back on absolute names.
590
591 \f
592 version 1.13.6 - Paul Eggert, 1999-08-11.
593
594 * An --exclude pattern containing / now excludes a file only if it matches an
595 initial prefix of the file name; a pattern without / continues to
596 exclude a file if it matches any file name component.
597
598 * The protocol for talking to rmt has been extended slightly.
599 Open flags are now communicated in symbolic format as well as numeric.
600 The symbolic format (e.g., "O_WRONLY|O_CREAT|O_TRUNC") is for portability
601 when rmt is operating on a different operating system from tar.
602 The numeric format is retained, and rmt uses it if symbolic format is absent,
603 for backward compatibility with older versions of tar and rmt.
604
605 * When writing GNU tar format headers, tar now uses signed base-64
606 for values that cannot be represented in unsigned octal.
607 This supports larger files (2**66 - 1 bytes instead of 2**33 - 1 bytes),
608 larger uids, negative time stamps, etc.
609
610 * When extracting files with unknown ownership, tar now looks up the
611 uid and gid "nobody" on hosts whose headers do not define UID_NOBODY
612 and GID_NOBODY, and falls back on uid/gid -2 if there is no "nobody".
613
614 * tar -t --numeric-owner now prints numeric uids and gids, not symbolic.
615
616 * New option -y or --bzip2 for bzip2 compression, by popular request.
617
618 \f
619 version 1.13.5 - Paul Eggert, 1999-07-20.
620
621 * Do the delayed updates of file metadata even after a fatal error.
622
623 \f
624 version 1.13.4 - Paul Eggert, 1999-07-20.
625
626 * Do not chmod unless we are root or the -p option was given;
627 this matches historical practice.
628
629 \f
630 version 1.13.3 - Paul Eggert, 1999-07-16.
631
632 * A path name is excluded if any of its file name components matches an
633 excluded pattern, even if the path name was specified on the command line.
634 Also see 1.13.6 for later changes in this area.
635
636 \f
637 version 1.13.2 - Paul Eggert, 1999-07-14.
638
639 * Bug reporting address changed to <bug-tar@gnu.org>.
640
641 \f
642 version 1.13.1 - Paul Eggert, 1999-07-12.
643
644 * Bug fixes only.
645 \f
646 version 1.13 - Paul Eggert, 1999-07-08.
647
648 * Support for large files, e.g., files larger than 2 GB on many 32-bit hosts.
649 Also, support for larger uids, device ids, etc.
650 * Many bug fixes and porting fixes.
651 * This release is only for fixes. A more ambitious test release,
652 with new features, is available as part of the paxutils. Please see:
653 ftp://alpha.gnu.org/gnu/paxutils/
654 The fixes in this release are intended to be merged with paxutils
655 at some point, but they haven't been merged yet.
656 * An interim GNU tar alpha had new --bzip2 and --ending-file options,
657 but they have been removed to maintain compatibility with paxutils.
658 Please try --use=bzip2 instead of --bzip2.
659 \f
660 Version 1.12 - François Pinard, 1997-04.
661
662 Sensitive matters
663 * Use shell globbing patterns for --label, instead of regular expressions.
664 * Do not quote anymore internally over the quoting done by the shell.
665
666 Output for humans
667 * Offer internationalization capabilities of most recent GNU gettext.
668 * Messages available in many more languages, thanks to all translators!
669 * Usage of ISO 8601 dates in listings, instead of local American dates.
670 * More normalization and cleanup in error messages.
671
672 Creation
673 * For helping using tar with find, offer a --no-recursion option.
674 * Implement --numeric-owner for ignoring symbolic names at create time.
675 * New --owner, --group --mode options, still preliminary.
676 * Recognize creating an archive on /dev/null, so Amanda works faster.
677 * Object to the creation of an empty archive (like in `tar cf FILE').
678 * Barely start implementing --posix and POSIXLY_CORRECT.
679
680 Extraction
681 * Make a better job at restoring file and directory attributes.
682 * Automatically attempt deleting existing files when in the way.
683 * Option --unlink-first (-U) removes most files prior to extraction.
684 * Option --recursive-unlink removes non-empty directories when in the way.
685 * Option --numeric-owner ignores owner/group names, it uses UID/GID instead.
686 * Use global umask when creating missing intermediate directories.
687 * When symlinks are not available, extract symbolic links as hard links.
688 * Diagnose extraction of contiguous files as regular files.
689 * New --backup, --suffix and --version-control options.
690
691 Various changes
692 * Better support of huge archives with --tape-length and --totals.
693 * Rename option --read-full-blocks (-B) to --read-full-records (-B).
694 * Rename option --block-size (-b) to --blocking-factor (-b).
695 * Rename option --record-number (-R) to --block-number (-R).
696 * With --block-number (-R), report null blocks and end of file.
697 * Implement --record-size for introducing a size in bytes.
698 * Delete --block-compress option and rather decide it automatically.
699 * Rename option --modification-time to --touch.
700
701 Many bugs are squashed, while others still run free.
702 \f
703 Version 1.11.8 - François Pinard, 1995-06.
704
705 * Messages available in French, German, Portuguese and Swedish.
706 * The distribution provides a rudimentary Texinfo manual.
707 * The device defaults to stdin/stdout, unless overridden by the installer.
708 * Option --sparse (-S) should work on more systems.
709 * Option --rsh-command may select an alternative remote shell program.
710
711 Most changes are internal, and should yield better portability.
712 \f
713 Version 1.11.2 - Michael Bushnell, 1993-03.
714
715 * Changes in backup scripts: cleaned up considerably; notices error
716 conditions better over rsh; DUMP_REMIND_SCRIPT is now an option in
717 backup-specs; new file dump-remind is an example of a
718 DUMP_REMIND_SCRIPT.
719
720 * Superfluous "Reading dirname" was a bug; fixed.
721
722 * Incompatibility problems with a bug on Solaris are fixed.
723
724 * New option --gzip (aliases are --ungzip and -z); calls gzip instead
725 of compress. Also, --use-compress-program lets you specify any
726 compress program. --compress-block is renamed --block-compress and
727 now requires one of the three compression options to be specified.
728
729 * Several error messages are cleaned up.
730
731 * Directory owners are now set properly when running as root.
732
733 * Provide DUMP_REMIND_SCRIPT in backup-specs as a possible option
734 for --info-script.
735
736 * Behave better with broken rmt servers.
737
738 * Dump scripts no longer use --atime-preserve; this causes a nasty probem.
739
740 * Several Makefile cleanups.
741 \f
742 Version 1.11.1 - Michael Bushnell, 1992-09.
743
744 * Many bug fixes.
745 \f
746 Version 1.11 - Michael Bushnell, 1992-09.
747 Version 1.10.16 - 1992-07.
748 Version 1.10.15 - 1992-06.
749 Version 1.10.14 - 1992-05.
750 Version 1.10.13 - 1992-01.
751
752 * Many bug fixes.
753
754 * Now uses GNU standard configure, generated by Autoconf.
755
756 * Long options now use `--'; use of `+' is deprecated and support
757 for it will eventually be removed.
758
759 * New option --null causes filenames read by -T to be
760 null-terminated, and causes -C to be ignored.
761
762 * New option --remove-files deletes files (but not directories)
763 after they are added to the archive.
764
765 * New option --ignore-failed-read prevents read-errors from affecting
766 the exit status.
767
768 * New option --checkpoint prints occasional messages as the tape
769 is being read or written.
770
771 * New option --show-omitted-dirs prints the names of directories
772 omitted from the archive.
773
774 * Some tape drives which use a non-standard method of indicating
775 end-of-tape now work correctly with multi-tape archives.
776
777 * --volno-file: Read the volume number used in prompting the user
778 (but not in recording volume ID's on the archive) from a file.
779
780 * When using --multi-volume, you can now give multiple -f arguments;
781 the various tape drives will get used in sequence and then wrap
782 around to the beginning.
783
784 * Remote archive names no longer have to be in /dev: any file with a
785 `:' is interpreted as remote. If new option --force-local is given,
786 then even archive files with a `:' are considered local.
787
788 * New option --atime-preserve restores (if possible) atimes to
789 their original values after dumping the file.
790
791 * No longer does tar confusingly dump "." when you don't tell it
792 what to dump.
793
794 * When extracting directories, tar now correctly restores their
795 modification and access times.
796
797 * Longnames support is redone differently--long name info directly
798 precedes the long-named file or link in the archive, so you no
799 longer have to wait for the extract to hit the end of the tape for
800 long names to work.
801 \f
802 Version 1.10 - Michael Bushnell, 1991-07.
803
804 * Filename to -G is optional. -C works right. Names +newer and
805 +newer-mtime work right.
806
807 * -g is now +incremental, -G is now +listed-incremental.
808
809 * Sparse files now work correctly.
810
811 * +volume is now called +label.
812
813 * +exclude now takes a filename argument, and +exclude-from does
814 what +exclude used to do.
815
816 * Exit status is now correct.
817
818 * +totals keeps track of total I/O and prints it when tar exits.
819
820 * When using +label with +extract, the label is now a regexp.
821
822 * New option +tape-length (-L) does multi-volume handling like BSD
823 dump: you tell tar how big the tape is and it will prompt at that
824 point instead of waiting for a write error.
825
826 * New backup scripts level-0 and level-1 which might be useful
827 to people. They use a file "backup-specs" for information, and
828 shouldn't need local modification. These are what we use to do
829 all our backups at the FSF.
