=head1 DESCRIPTION
The first argument to find() is either a hash reference describing the
-operations to be performed for each file, a code reference, or a string
-that contains a subroutine name. If it is a hash reference, then the
-value for the key C<wanted> should be a code reference. This code
-reference is called I<the wanted() function> below.
+operations to be performed for each file, or a code reference.
-Currently the only other supported key for the above hash is
-C<bydepth>, in presense of which the walk over directories is
-performed depth-first. Entry point finddepth() is a shortcut for
-specifying C<{ bydepth => 1}> in the first argument of find().
+Here are the possible keys for the hash:
+
+=over 3
+
+=item C<wanted>
+
+The value should be a code reference. This code reference is called
+I<the wanted() function> below.
+
+=item C<bydepth>
+
+Reports the name of a directory only AFTER all its entries
+have been reported. Entry point finddepth() is a shortcut for
+specifying C<{ bydepth => 1 }> in the first argument of find().
+
+=item C<follow>
+
+Causes symbolic links to be followed. Since directory trees with symbolic
+links (followed) may contain files more than once and may even have
+cycles, a hash has to be built up with an entry for each file.
+This might be expensive both in space and time for a large
+directory tree. See I<follow_fast> and I<follow_skip> below.
+If either I<follow> or I<follow_fast> is in effect:
+
+=over 6
+
+=item
+
+It is guarantueed that an I<lstat> has been called before the user's
+I<wanted()> function is called. This enables fast file checks involving S< _>.
+
+=item
+
+There is a variable C<$File::Find::fullname> which holds the absolute
+pathname of the file with all symbolic links resolved
+
+=back
+
+=item C<follow_fast>
+
+This is similar to I<follow> except that it may report some files
+more than once. It does detect cycles however.
+Since only symbolic links have to be hashed, this is
+much cheaper both in space and time.
+If processing a file more than once (by the user's I<wanted()> function)
+is worse than just taking time, the option I<follow> should be used.
+
+=item C<follow_skip>
+
+C<follow_skip==1>, which is the default, causes all files which are
+neither directories nor symbolic links to be ignored if they are about
+to be processed a second time. If a directory or a symbolic link
+are about to be processed a second time, File::Find dies.
+C<follow_skip==0> causes File::Find to die if any file is about to be
+processed a second time.
+C<follow_skip==2> causes File::Find to ignore any duplicate files and
+dirctories but to proceed normally otherwise.
-The wanted() function does whatever verifications you want.
-$File::Find::dir contains the current directory name, and $_ the
-current filename within that directory. $File::Find::name contains
-C<"$File::Find::dir/$_">. You are chdir()'d to $File::Find::dir when
-the function is called. The function may set $File::Find::prune to
-prune the tree.
-File::Find assumes that you don't alter the $_ variable. If you do then
-make sure you return it to its original value before exiting your function.
+=item C<no_chdir>
+
+Does not C<chdir()> to each directory as it recurses. The wanted()
+function will need to be aware of this, of course. In this case,
+C<$_> will be the same as C<$File::Find::name>.
+
+=item C<untaint>
+
+If find is used in taint-mode (-T command line switch or if EUID != UID
+or if EGID != GID) then internally directory names have to be untainted
+before they can be cd'ed to. Therefore they are checked against a regular
+expression I<untaint_pattern>. Note, that all names passed to the
+user's I<wanted()> function are still tainted.
+
+=item C<untaint_pattern>
+
+See above. This should be set using the C<qr> quoting operator.
+The default is set to C<qr|^([-+@\w./]+)$|>.
+Note that the paranthesis which are vital.
+
+=item C<untaint_skip>
+
+If set, directories (subtrees) which fail the I<untaint_pattern>
+are skipped. The default is to 'die' in such a case.
+
+=back
+
+The wanted() function does whatever verifications you want.
+C<$File::Find::dir> contains the current directory name, and C<$_> the
+current filename within that directory. C<$File::Find::name> contains
+the complete pathname to the file. You are chdir()'d to C<$File::Find::dir> when
+the function is called, unless C<no_chdir> was specified.
+When <follow> or <follow_fast> are in effect there is also a
+C<$File::Find::fullname>.
+The function may set C<$File::Find::prune> to prune the tree
+unless C<bydepth> was specified.
This library is useful for the C<find2perl> tool, which when fed,
find2perl / -name .nfs\* -mtime +7 \
- -exec rm -f {} \; -o -fstype nfs -prune
+ -exec rm -f {} \; -o -fstype nfs -prune
produces something like:
sub wanted {
/^\.nfs.*$/ &&
- (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_)) &&
+ (($dev, $ino, $mode, $nlink, $uid, $gid) = lstat($_)) &&
int(-M _) > 7 &&
unlink($_)
||
- ($nlink || (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_))) &&
+ ($nlink || (($dev, $ino, $mode, $nlink, $uid, $gid) = lstat($_))) &&
$dev < 0 &&
($File::Find::prune = 1);
}
-Set the variable $File::Find::dont_use_nlink if you're using AFS,
+Set the variable C<$File::Find::dont_use_nlink> if you're using AFS,
since AFS cheats.
-C<finddepth> is just like C<find>, except that it does a depth-first
-search.
Here's another interesting wanted function. It will find all symlinks
that don't resolve:
sub wanted {
- -l && !-e && print "bogus link: $File::Find::name\n";
+ -l && !-e && print "bogus link: $File::Find::name\n";
}
-=head1 BUGS
+See also the script C<pfind> on CPAN for a nice application of this
+module.
+
+=head1 CAVEAT
+
+Be aware that the option to follow symblic links can be dangerous.
+Depending on the structure of the directory tree (including symbolic
+links to directories) you might traverse a given (physical) directory
+more than once (only if C<follow_fast> is in effect).
+Furthermore, deleting or changing files in a symbolically linked directory
+might cause very unpleasant surprises, since you delete or change files
+in an unknown directory.
-There is no way to make find or finddepth follow symlinks.
