finddepth - traverse a directory structure depth-first
use File::Find;
find(\&wanted, '/foo','/bar');
sub wanted { ... }
use File::Find;
finddepth(\&wanted, '/foo','/bar');
sub wanted { ... }
wanted function does whatever verifications you want.
$File::Find::dir contains the current directory name, and $_
the current filename within that directory. $File::Find::name contains
"$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 $_ variable. If
you do then make sure you return it to its original value before exiting
your function.
This library is primarily for the find2perl tool, which when fed,
find2perl / -name .nfs\* -mtime +7 \
-exec rm -f {} \; -o -fstype nfs -prune
produces something like:
sub wanted {
/^\.nfs.*$/ &&
(($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_)) &&
int(-M _) > 7 &&
unlink($_)
||
($nlink || (($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, since AFS cheats.
finddepth is just like 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";
}
