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: -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 $File::Find::prune to -prune the tree. +=over 3 + +=item C<wanted> + +The value should be a code reference. This code reference is called +I<the wanted() function> below. + +=item C<bydepth> + +Reports the name of a directory only AFTER all its entries +have been reported. Entry point finddepth() is a shortcut for +specifying C<{ bydepth => 1 }> in the first argument of find(). + +=item C<follow> + +Causes symbolic links to be followed. Since directory trees with symbolic +links (followed) may contain files more than once and may even have +cycles, a hash has to be built up with an entry for each file. +This might be expensive both in space and time for a large +directory tree. See I<follow_fast> and I<follow_skip> below. +If either I<follow> or I<follow_fast> is in effect: + +=over 6 + +=item * + +It is guarantueed that an I<lstat> has been called before the user's +I<wanted()> function is called. This enables fast file checks involving S< _>. + +=item * + +There is a variable C<$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. -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. +Unless C<follow> or C<follow_fast> is specified, for compatibility +reasons (find.pl, find2perl) there are in addition the following globals +available: C<$File::Find::topdir>, C<$File::Find::topdev>, C<$File::Find::topino>, +C<$File::Find::topmode> and C<$File::Find::topnlink>.
