1 GNU findutils NEWS - User visible changes. -*- outline -*- (allout)
2 * Major changes in release 4.3.0-CVS
4 ** Documentation Changes
6 The manual now includes a "Worked Examples" section which talks about
7 the various ways in which findutils can be used to perform common
8 tasks, and why some of these alternatives are better than others.
10 The -I option of xargs (which is required by the POSIX standard) is
13 Many documentation readability enhancements and proofreading fixes
14 were contributed by Aaron Hawley.
18 *** Functional changes in locate
20 The "--regex" option of locate now assumes the regular expression to
21 be in the same syntax as is used in GNU Emacs, though this can be
22 changed with the new option --regextype. This is a change from the
23 existing behaviour (which was to use POSIX Basic Regular Expressions).
24 Since this featrue is releatively new anyway, I though it was more
25 useful to have compatibility between regular expression handling in
26 find and locate than to maintain the short-lived previous behaviour of
29 The locate program now also supports a "--regextype" long option which
30 controls which regular expression syntax is understood by locate.
31 This is a long option and has no single-letter 'short option'
34 *** Functional changes in find
36 The regular expression syntax understood by "find" can be changed with
37 the -regextype option; this option is positional, meaning that you can
38 have several tests, each using a distinct syntax (this is not
39 recommended practice however).
41 The default regular expression syntax is substantially the same as
42 that recognised by GNU Emacs, except for the fact that "." will match
45 The leaf optimisation can be disabled with the configure option
46 "--disable-leaf-optimisation", which is equivalent to specifying
47 "-noleaf" on all find command lines. This is useful for systems
48 having filesystems which do not provide traditional Unix behaviour for
49 the link cound on directories (for example Cygwin and the Solaris 9
54 *** Bug Fixes for find
56 The -iregex test now works once again on systems that lack
57 re_search() (that is, systems on which findutils needs to use the
58 gnulib version of this function).
60 find -regex now once again uses GNU Emacs-compatible regular
63 If invoked with stderr closed, the -fprint and -fprintf actions now no
64 longer cause error messages to be sent into the output file.
66 If the link count of a directory is less that two, the leaf
67 optimisation is now disabled for that directory. This should allow
68 searching of non-Unix filesystems to be more reliable on systems that
69 don't take the trouble to make their filesystems look like traditional
70 Unix filesystems. Some filesystems don't even take the trouble to
71 have a link count of less than two and for these, -noleaf is still
72 required unless --disable-leaf-optimisation was used at configure time.
74 The "%Y" directive for the -orintf action now no longer changes find's
75 idea of the mode of the file, so this means among other things that
76 "-printf %Y %y" now works properly. This is Savannah bug #13973.
78 * Major changes in release 4.2.23
80 ** Documentation Changes
82 The -L and -I options of xargs are currently incompatible (but should
85 Improved the documentation for -execdir and -okdir.
87 ** Functional Changes to updatedb
89 File names ending in "/" which are specified as an argument to
90 --prunepaths (or in $PRUNEPATHS) don't work, so we now issue an error
91 message if the user tries to do that. The obvious exception of course
92 is "/" which does work and is not rejected.
95 * Major changes in release 4.2.22
99 If a directory entry searched with "find -L" is a symbolic link to
100 ".", we no longer loop indefinitely. This problem affected find
101 versions 4.2.19, 4.2.20 and 4.2.21. This problem allows users to make
102 "find" loop indefinitely. This is in effect a denial of service and
103 could be used to prevent updates to the locate database or to defeat
104 file security checks based on find. However, it should be noted that
105 you should not use "find -L" in security-sensitive scenarios.
109 None in this release.
111 ** Functional Changes to locate
113 A locate database can now be supplied on stdin, using '-' as a element
114 of the database-path. If more than one database-path element is '-',
115 later instances are ignored.
117 A new option to locate, '--all' ('-A') causes matches to be limited to
118 entries which match all given patterns, not entries which match
119 one or more patterns.
121 ** Documentation Changes
123 Some typos in the manual pages have been fixed. Various parts of the
124 manual now point out that it is good practice to quote the argument of
125 "-name". The manpage now has a "NON-BUGS" section which explains some
126 symptoms that look like bugs but aren't. The explanations of the "%k"
127 and "%b" directives to "find -printf" have been imrpoved.
130 * Major changes in release 4.2.21
131 ** Functional Changes to find
133 The GNU extension "find ... -perm +MODE" has been withdrawn because it
134 is incompatible with POSIX in obscure cases like "find ... -perm ++r".
135 Use the new syntax "find ... -perm /MODE" instead. Old usages will
136 still continue to work, so long as they don't conflict with POSIX.
138 If the output is going to a terminal, the -print, -fprint, -printf and
139 -fprintf actions now quote "unusual" characters to prevent unwanted
140 effects on the terminal. See "Unusual Characters in File Names" for
141 further details. There is no change to the behaviour when the output
142 is not going to a terminal. The locate program does the same thing,
143 unless the -0 option is in effect (in which case the filenames are
146 ** Functional Changes to locate
148 The locate command will now read each locate database at most once.
149 This means that if you are using multiple databases and are searching
150 for more than one name, the results will now be printed in a different
151 order (and if you specified a small limit with --limit, you may get a
152 different set of results).
154 A new option '--print' for locate causes it to print the matching
155 results even if the '--count' or '--statistics' option is in effect.
158 find /blah/blah/blah -depth -empty now works once again.
160 The -regex and -iregex tests of find now correctly accept POSIX Basic
161 Regular Expressions. (Savannah bug #12999)
163 The updatedb program now works on systems where "su" does not support
164 the "-s" option, for example Solaris.
166 * Major changes in release 4.2.20
167 ** Internationalization and Localization
168 Updated Vietnamese and Dutch translations.
171 Minor bugfix affecting only those who compile from the CVS repository,
172 as opposed to those who compile from the source releases.
174 * Major changes in release 4.2.19
177 find should now no longer hang on systems which lack the O_NOFOLLOW
178 flag to open(2) and which are clients of an unresponsive NFS server
179 (Savannah bug #12044).
181 We now avoid inappropriately failing for "find -L foo" or "find -H
182 foo" if foo is a symbolic link (Savannah bug #12181). Previously we
183 used to fail with the error message "Too many levels of symbolic
186 "find . -false -exec foo {} +" no longer runs an extra instance of foo
187 when find exits (Savannah bug #12230).
189 If the chdir() safety check fails but we can no longer get back to
190 where we started, exit with an explanatory (fatal) error message.
191 This does not happen on GNU/Linux and FreeBSD because the safety check
192 is not needed (the security problem the safety check protects against
193 is prevented in a cleaner way on those systems).
195 "make distclean" no longer deletes regex.c (which "make all" needs).
197 ** Functionality Changes
198 "find -printf "%h\n" will now print "." for files in the current directory.
199 Previously it printed nothing (but there was a bug in the %h
200 implementation anyway). This fixes Savannah bug #12085.
202 Should now build (again) on non-C99-compliant systems.
204 ** Documentation enhancements
205 Fixed some typos and clarified wording in "Working with automounters".
207 ** Internationalization and Localization
208 New Vietnamese message translation.
210 * Major changes in release 4.2.18
212 *** "find -depth" was missing out non-leaf directories when they contain
213 non-directories. This affected findutils releases 4.2.15,
214 4.2.16 and 4.2.17, but the bug is now fixed.
215 *** Find no longer hangs on systems which are clients of unresponsive
217 ** Documentation improvements
218 *** Improvements and corrections to the find.1 manpage, including corrections to the descriptions of -H and -L.
220 * Major changes in release 4.2.17
222 *** bug #11861 undefined symbol "basename" on IRIX 5.3
223 *** bug #11865 xargs -i regression (as compared to findutils-4.2.12)
224 *** bug #11866 Typo in pred_okdir renders it useless (affecting 4.2.16 only)
225 *** patch #3723 fix recent process_top_path change (for -execdir on /)
226 *** Fixing bug #11866 and applying patch #3723 made -execdir work much better.
227 *** find bar/baz/ugh now works again if baz is a symbolic link (broken
230 * Major changes in release 4.2.16
231 ** Functionality Changes
232 *** Updated the message catalogues for the translated messages.
233 *** The subfs filesystem is now treated the same as the autofs
235 *** New translations: Belarusian, Catalan, Greek, Esperanto,
236 Finnish, Irish, Croatian, Hungarian, Japanese, Luganda,
237 Malay, Romanian, Slovenian, Serbian, Chinese (simplified).
240 *** The -execdir action now works correctly for files named on the
243 * Major changes in release 4.2.15
244 ** Functionality Changes
245 *** locate now supports matching regular expression (--regex).
246 *** --enable-d_type-optimization (introduced in findutils 4.2.13) is now turned on by default.
248 * Major changes in release 4.2.14
249 ** Functionality Changes
250 *** New options -L, -P, -H for locate. The work in the same was as the same options for find.
252 *** Don't include the "findutils/find/testsuite/find.gnu" subdirectory in the
253 distributed tar file more than once.
254 *** Should now build on Solaris once again.
255 *** -xtype and -printf %Y now work correctly for symbolic links once again
256 ** Documentation improvements
257 *** All options for "locate" are now documented
259 * Major changes in release 4.2.13
260 ** Performance Enhancements
261 *** On Linux and some other systems, a large performance improvement,
262 because we can eliminate many of the calls to lstat() (in extreme
263 cases, 99% of them). Limited testing shows a 2x speedup on NFS
264 filesystems. Other systems which can make use of this enhancement
265 include Mac OS X and *BSD.
267 * Major changes in release 4.2.12
268 ** Functionality Changes
269 *** find is now POSIX-compliant, as far as I know.
270 *** -exec ... {} + now works.
271 *** New actions -execdir and -okdir which are like -exec and -ok but more secure.
272 *** "locate -w" is now a synonym for "locate --wholepath".
273 *** An empty path entry in the locate database path (for example "::" in
274 $LOCATE_PATH or in the argument to "locate -d") is taken to mean
275 the default database, whose name is hard-coded in locate.
277 *** If find or xargs cannot write to stdout, for example because
278 output is redirected to a file and the disk is full, the
279 relevant program will return a non-zero exit status.
281 * Major changes in release 4.2.11
283 *** Compilation fix for systems without EOVERFLOW.
284 *** More helpful error message if you make a mistake with (, ), -o or -a.
285 ** Functionality Changes
286 *** If you have unclosed parentheses on the find command line,
287 or any of a number of similar problems, find will now produce
288 a more helpful error message.
289 *** locate -b is now a synonym for locate --basename
290 *** locate now supports a --statistics (or -S) option, which prints some
291 statistics about the locate databases.
292 *** Implemented the -samefile option.
293 ** Documentation improvements
294 *** New chapter in the manual, "Security Considerations".
295 *** Better documentation for -prune (Mainly thanks to Stepan Kasal)
297 *** locate's options -i and -w now work with the -e option (previously a bug
300 * Major changes in release 4.2.10
302 *** Portability fix for fstype.c: should now compile on UNICOS, and possibly
303 also produce useful results on BeOS and Dolphin, perhaps other
306 * Major changes in release 4.2.9
307 ** Functionality Changes
308 *** xargs no longer treats a line containing only an underscore as a logical end-of-file. To obtain the behaviour that was previously the default, use "-E_".
309 *** xargs now supports the POSIX options -E, -I and -L. These are synonyms
310 for the existing options -e, -i and -l, but the latter three are
313 *** xargs -n NUM now invokes a command as soon as it has NUM arguments.
314 Previously, it waited until NUM+1 items had been read, and then
315 invoked the command with NUM arguments, saving the remaining one
317 *** If "find -L" discovers a symbolic link loop, an error message is issued.
318 *** If you specify a directory on the find command line, but -prune
319 is applied to it, find will no longer chdir() into it anyway.
320 ** Documentation improvements
321 *** The precise interpretation of the arguments to the -atime, -ctime
322 and similar tests in find has been documented more clearly.
324 * Major changes in release 4.2.8
325 *** Bugfix to the findutils 4.2.7 automount handling on Solaris. This
326 worked to some extent in findutils-4.2.7, but is much improved in
329 * Major changes in release 4.2.7
330 ** Functionality Changes
331 *** xargs can now read a list of arguments from a named file, allowing
332 the invoked program to use the same stdin as xargs started with
333 (for example ``xargs --arg-file=todo emacs'').
334 ** Documentation improvements
335 *** The Texinfo manual now has an extra chapter, "Error Messages". Most
336 error messages are self-explanatory, but some of the ones which
337 are not are explained in this chapter.
339 *** Avoid trying to link against -lsun on UNICOS, which doesn't need it or
341 *** Bugfix to the findutils 4.2.6 automount handling (which hadn't been enabled
343 *** Reenabled internationalisation support (which had been accidentally
344 disabled in findutils-4.2.5).
346 * Major changes in release 4.2.6
348 *** find now copes rather better when a directory appears to change just as
349 it is about to start examining it, which happens with automount.
350 This is because automount mounts filesystems as you change
351 directory into them. This should resolve Savannah bugs #3998,
354 * Major changes in release 4.2.5
355 ** Functionality Changes
356 *** The POSIX options -H and -L are supported. These control whether or not
357 find will follow symbolic links.
358 *** The BSD option -P is also now supported (though in any case
360 ** Documentation improvements
361 *** Better documentation for "xargs -i".
363 *** "make install" now respects DESTDIR when generating localstatedir.
364 (this is only relevant if you are installing to some location
365 other than the one that you indictaed when you ran "configure").
366 *** Compatible with automake versions 1.8 and 1.9.
367 *** Build problems on UNICOS now fixed, though the linker will still generate
368 warnings because we try to link with the nonexistent library
369 "-lsun". Edit $(LIBS) to work around this problem.
371 * Major changes in release 4.2.4
372 ** Functionality Changes
373 *** If your system sort command has a working "-z" option, updatedb will
374 now correctly handle newline characters in filenames (as will
376 *** xargs now uses 128Kb of command line by default (less if the system
377 doesn't support that much).
378 *** If you specify a 'find' option after non-option, a warning message
379 is now issued. Options should be specified immediately after the
380 list of paths to search. These warnings are enabled if you
381 specify the -warn option, or if stdin is a tty. They are diabled
382 by the use of the -nowarn option.
383 *** Like find, the locate program now supports an option --null (short form -0)
384 which changes the result separator from newline to NULL.
385 *** Locate supports the option -c (long form --count) which suppresses normal
386 output but prints on stdout the number of results produced (like
388 *** Locate supports the option -l (long form --limit) which limits the
389 number of results. This is useful if you only want to find out if
390 there are copies of a certain file on the system, but don't want
391 to wait for the entire locate database to be searched.
392 *** Locate now has an option --basename which forces the specified pattern to
393 be matched against the basename of the entries in the locate
394 database, rather than the whole name. The default behaviour
395 (matching against the whole name of the file including all the
396 parent directory names) corresponds to the option --wholename.
397 *** updatedb has a new option, --findoptions, that can be used to
398 pass extra options through to the find command that it uses.
400 *** "find -printf '%H\n'" now works (rather than segfaulting) on
401 systems that have non-writable string constants.
402 *** Better POSIX compliance for the -s option to xargs (out of range
403 values should just result in bounding to the correct range, not an
404 error, so now we just print a warning message and adjust the
406 *** Corrected section numbers of manual page cross-references
408 * Major changes in release 4.2.3
409 ** Functionality Changes
410 *** Added new action -delete which deletes things that find matches.
411 *** Added new action -quit which causes find to exit immediately.
412 *** A new format directive '%D' for "find -printf" prints the device number.
413 *** The -ls predicate no longer truncates user or group names.
414 *** Added new option "-d" which is a synonym for "-depth" for compatibility
415 with Mac OS, OpenBSD and FreeBSD. This option is already
416 deprecated since the POSIX standard specifies "-depth".
417 *** Added two new format specifiers to the -printf action; these are
418 %y and %Y. They indicate the type of the file as a single letter;
419 these are the same latters as are used by the "-type" test.
420 *** If a parent directory changes during the execution of find,
421 the error message we issue identifies the nature of the change
422 (for example the previous and current inode numbers of the
423 directory we've just returned out of).
425 *** Non-functional code changes to silence compiler warnings.
427 * Major changes in release 4.2.2
428 ** Documentation improvements
429 *** "find ... -exec {}+" is not yet supported.
431 *** Fixed compilation problems on Solaris, RedHat EL AS 2.1, Irix, AIX
432 *** Work around possible compiler bug on HP-UX 11.23 for ia64
433 *** The built-in internationalisation support now works again.
435 *** We now import the gnulib source in the way it is intended to be used,
436 which means among other things that we only have one config.h file
438 *** Functions which findutils requires but which are not present in
439 gnulib are now defined in "libfind.a". This is in the lib
440 directory, while gnulib is in the gnulib subdirectory.
441 *** Fixed a typo in the address of the FSF in many of the file headers.
443 * Major changes in release 4.2.1
445 *** 'find -name \*bar now matches .foobar, because the POSIX standard
446 requires it, as explained at
447 http://standards.ieee.org/reading/ieee/interp/1003-2-92_int/pasc-1003.2-126.html
449 * Major changes in release 4.2.1
451 *** find -iname now works correctly on systems that have an fnmatch() function
452 that does not support FNM_CASEFOLD
453 *** updatedb now uses signal names for "trap" instead of numbers,
454 as per bug #9465 (see http://www.opengroup.org/onlinepubs/009695399/utilities/trap.html)
455 *** Better support for systems lacking intmax_t
457 **** findutils now uses a newer version of gnulib (dated 2004-10-17).
459 * Major changes in release 4.2.0
460 ** Functionality Changes
461 *** xargs now works better when the environment variables are very extensive.
462 The xargs command used to run into difficulties if the environment
463 data contained more than 20480 bytes.
464 *** New options -wholename and -iwholename
465 As per the GNU Projecvt coding standard, These are preferred over
466 the -path and -ipath options. Using -ipath now generates a warning,
467 though -path does not (since HPUX also offers -path).
468 *** The environment variable FIND_BLOCK_SIZE is now ignored.
469 *** New option "-ignore_readdir_race"
470 silences an error messages which would otherwise occur if a file is removed
471 after find has read it from the directory using readdir(), but before
472 find stats the file. There is also an option
473 -noignore_readdir_race which has the opposite effect.
474 ** Documentation improvements
475 *** The -size option of find is now documented in more detail
476 *** POSIX compliance and GNU extensions
477 The find manual page also now includes a section
478 which describes the relationship between the features of GNU
479 find and the POSIX standard. Some other small improvements
480 to the find and xargs manual pages have been made.
481 *** The argument to the -fprintf directive is now better documented.
482 The escape code '\0' for the `-printf' predicate of find is now
483 documented, and the documentation for the %k and %b specifiers
485 *** xargs -i is now more clearly documented.
487 *** locate 'pa*d' will now find /etc/passwd (if it exists, of course)
488 *** xargs standard input is not inherited by child processes
489 If the command invoked by xargs reads from its standard input,
490 it now gets nothing, as opposed to stealing data from the
491 list of files that xargs is trying to read.
492 *** Better support for 64-bit systems.
493 *** The command "xargs -i -n1" now works as one might expect,
494 I think this is a strange thing to want to do.
495 *** Arguments to find -mtime that are too large are now diagnosed
496 Previously, this just used to cause find just to do the wrong thing.
497 *** updatedb is now somewhat more robust
498 The updatedb shell script now does not generate an empty
499 database if it fails.
500 *** Sanity-check on some data read from locatedb
501 Locate now detects some types of file corruption in the
503 *** The %k format specifier for -fprintf now works
504 This was broken in 4.1.20.
506 * Major changes in release 4.1.20:
507 ** New maintainer, James Youngman <jay@gnu.org>
508 ** As far as I know, this is the first release after 4.1.7, but I've left
510 ** We now use an "imported" version of gnulib, rather than including
511 a copy of the gnulib code in our CVS repository. There are no
512 differences in the build instructions, though (unless you are
513 building directly from CVS, in which case please read the file
515 ** There are no (deliberate) functional changes in version 4.1.20.
517 * Major changes in release 4.1.7:
518 fix problem so that default "-print" is added when "-prune" is used.
519 security fixes related to directories changing while find is executing.
521 * Major changes in release 4.1.6:
522 correct bug in prune.
523 added --ignore-case option for locate
525 * Major changes in release 4.1.5:
526 Add support for large files
528 * Major changes in release 4.1.4:
529 bug fixes, more up-to-date languages.
531 * Major changes in release 4.1.3:
532 added internationalization and localization.
534 * Major changes in release 4.1.1:
535 attempt at successful compilation on many platforms after years of neglect
536 "--existing" option added to locate "--prunefs" option added to updatedb
538 * Major changes in release 4.1:
540 ** Distribution renamed to findutils.
541 ** updatedb is now a user command, installed in $exec_prefix/bin
542 instead of $exec_prefix/libexec.
543 ** A few problems in Makefiles and testsuite corrected.
545 * Major changes in release 4.0:
549 *** Man page for updatedb.
550 *** Man page for the locate database formats.
553 *** Takes less CPU time on long paths, because it uses chdir to descend
554 trees, so it does fewer inode lookups.
555 *** Does not get trapped in symbolic link loops when -follow is given.
556 *** Supports "-fstype afs" if you have /afs and /usr/afsws/include
557 and you configure using the --with-afs option.
558 *** New action -fls FILE; like -ls but writes to FILE.
561 *** Supports a new database format, which is 8-bit clean and
562 allows machines with different byte orderings and integer sizes to
563 share the databases. The new locate can also detect and read the
564 old database format automatically. The new databases are typically
565 30% or more larger than the old ones (due to allowing all 8 bits in
566 file names). Search times are approximately the same, or faster on
568 *** Warns if a file name database is more than 8 days old.
571 *** Takes command-line options.
574 *** Performance improved 10-20%.
575 *** The EOF string is not used when -0 is given.
576 *** Now has a test suite. Some minor bugs fixed as a result.
578 * Major changes in release 3.8:
580 ** case insensitive versions of -lname, -name, -path, -regex:
581 -ilname, -iname, -ipath, -iregex
582 ** %F directive for -printf, -fprintf to print file system type
584 * Major changes in release 3.7:
586 ** locate can search multiple databases
587 ** locate has an option to specify the database path
588 ** updatedb no longer goes into an infinite loop with some versions of tail
