I am pleased to announce the release of version 4.2.25 of GNU
GNU findutils is a set of software tools for finding files that match
certain criteria and for performing various operations on them.
Findutils includes the programs "find", "xargs" and "locate". More
information about findutils is available at
This is a "stable" release of findutils. It can be downloaded from
ftp://ftp.gnu.org/pub/gnu/findutils. The ftp.gnu.org site is very
busy, so you may find it more convenient to download findutils from
one of the mirror sites listed at http://www.gnu.org/order/ftp.html.
This release includes a range of changes, including both bugfixes and
small functional changes. All the changes since the previous stable
release are summarised below.
The principal change between findutils-4.2.23 and findutils-4.2.25 is
that the regular expression support in "find" is now once again
compatible with the traditional behaviour (that is, GNU Emacs-style
regular expression syntax). Alternative regular expression syntaxes
can be selected at runtime; indeed you can use more than one different
syntax in the same command line. See below for details.
Bugs in GNU findutils should be reported to the findutils bug tracker
at http://savannah.gnu.org/bugs/?group=findutils. Reporting bugs via
the web interface will ensure that you are automatically informed when
the bug has been fixed. General discussion of findutils takes place
on the bug-findutils mailing list. To join the 'bug-findutils'
mailing list, send email to <address@hidden>.
To verify the GPG signature of the release, you will need the public
key of the findutils maintainer, James Youngman. You can download
this from ftp://ftp.gnu.org/gnu/gnu-keyring.gpg. Alternatively, you
could query a PGP keyserver, but you will need to use one that can
cope with subkeys containing photos. Many older key servers cannot do
this. I use subkeys.pgp.net. I think that one works. See also the
"Downloading" section of http://www.gnu.org/software/findutils/.
* Major changes in release 4.2.25
** Bug Fixes
find -perm /440 (which should succeed if a file is readable by its
owner or group) now works. Previously there was a bug which caused
this to be treated as "find -perm 440".
Some files in the xargs test suite have been renamed to avoid problems
on operating systems whoch cannot distinguish filenames on the basis
of upper/lower case distinctions.
The software now builds on Cygwin, including the generated file
Findutils should now build once again on systems supporting AFS, but
this support has not recently been fully tested. Findutils should
also (once again) build on Cygwin.
** Other Changes
The test suite for find is now much more extensive.
* Major changes in release 4.2.24
** Documentation Changes
The manual now includes a "Worked Examples" section which talks about
the various ways in which findutils can be used to perform common
tasks, and why some of these alternatives are better than others.
The -I option of xargs (which is required by the POSIX standard) is
We now document the fact that find ensures that commands run by -ok
and -okdir don't steal find's input. Find does this by redirecting
the command's standard input from stdin.
Many documentation readability enhancements and proofreading fixes
were contributed by Aaron Hawley.
** Functional Changes
*** Functional changes in locate
The "--regex" option of locate now assumes the regular expression to
be in the same syntax as is used in GNU Emacs, though this can be
changed with the new option --regextype. This is a change from the
existing behaviour (which was to use POSIX Basic Regular Expressions).
Since this feature is releatively new anyway, I though it was more
useful to have compatibility between regular expression handling in
find and locate than to maintain the short-lived previous behaviour of
The locate program now also supports a "--regextype" long option which
controls which regular expression syntax is understood by locate.
This is a long option and has no single-letter 'short option'
*** Functional changes in find
The regular expression syntax understood by "find" can be changed with
the -regextype option; this option is positional, meaning that you can
have several tests, each using a distinct syntax (this is not
recommended practice however).
The default regular expression syntax is substantially the same as
that recognised by GNU Emacs, except for the fact that "." will match
The leaf optimisation can be disabled with the configure option
"--disable-leaf-optimisation", which is equivalent to specifying
"-noleaf" on all find command lines. This is useful for systems
having filesystems which do not provide traditional Unix behaviour for
the link count on directories (for example Cygwin and the Solaris 9
** Bug Fixes
*** Bug Fixes for find
The -iregex test now works once again on systems that lack
re_search() (that is, systems on which findutils needs to use the
gnulib version of this function).
find -regex now once again uses GNU Emacs-compatible regular
If invoked with stderr closed, the -fprint and -fprintf actions now no
longer cause error messages to be sent into the output file.
If the link count of a directory is less that two, the leaf
optimisation is now disabled for that directory. This should allow
searching of non-Unix filesystems to be more reliable on systems that
don't take the trouble to make their filesystems look like traditional
Unix filesystems. Some filesystems don't even take the trouble to
have a link count of less than two and for these, -noleaf is still
required unless --disable-leaf-optimisation was used at configure time.
The "%Y" directive for the -printf action now no longer changes find's
idea of the mode of the file, so this means among other things that
"-printf %Y %y" now works properly. This is Savannah bug #13973.
