9 version 1.15.2 (CVS version -- unreleased)
10
11 * New features
12
13 * Any number of -T (--files-from) options may be used in the command line.
14 The file specified with -T may include any valid `tar' options,
15 including another -T option.
16 Compatibility note: older versions of tar would only recognize -C
17 as an option name within the file list file. Now any file whose name
18 starts with - is handled as an option. To insert file names starting with
19 dash, use the --add-file option.
20
21 * List files containing null-separated file names are detected and processed
22 automatically. It is no longer necessary to give the --null option.
23
24 * New option --no-unquote disables the unquoting of input file names.
25 This is useful for processing output from `find dir -print0'.
26 An orthogonal option --unquote is provided as well.
27
28 * New option --test-label tests the archive volume label.
29 If an argument is specified, the label is compared against its value.
30 Tar exits with code 0 if the two strings match, and with code 2 if
31 they do not.
32
33 If no argument is given, the --verbose option is implied. In this case,
34 tar prints the label name if present and exits with code 0.
35
36 * New option --show-stored-names. When creating an archive in verbose mode,
37 it lists member names as stored in the archive, i.e., with any eventual
38 prefixes removed. The option is useful, for example, while comparing
39 `tar cv' and `tar tv' outputs.
40
41 * New option --to-command pipes the contents of archive members to the
42 specified command.
43
44 * New option --atime-preserve=system, which uses the O_NOATIME feature
45 of recent Linux kernels to avoid some problems when preserving file
46 access times.
47
48 * New option --restrict prohibits use of some potentially harmful tar
49 options. Currently it disables '!' escape in multi-volume name menu.
50
51 * The end-of-volume script (introduced with --info-script option) can
52 get current archive name from the environment variable TAR_ARCHIVE and
53 the volume number from the variable TAR_VOLUME. It can alter the
54 archive name by writing new name to the file descriptor 3.
55
56 * Better support for full-resolution time stamps. Tar cannot restore
57 time stamps to full nanosecond resolution, though, until the kernel
58 guys get their act together and give us a system call to set file time
59 stamps to nanosecond resolution.
60
61 * The -v option now prints time stamps only to 1-minute resolution,
62 not full resolution, to avoid using up too many output columns.
63 Nanosecond resolution is now supported, but that would be too much.
64
65 * Bug fixes
66
67 ** Allow non-option arguments to be interspersed with options.
68 ** When extracting or listing archives in old GNU format, tar
69 used to read an extra block of data after a long name header
70 if length of the member name was divisible by block size (512).
71 Consequently, the file pointer was set off and the next member
72 was not processed correctly.
73 ** Previous version created invalid archives when files shrink
74 during reading.
75 ** Compare mode (tar d) hanged when trying to compare file contents.
76 ** Previous versions in certain cases failed to restore directory
77 modification times.

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