- find - traverse a file tree
-
- 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 { ... }

- The _w_a_n_t_e_d() 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 _c_h_d_i_r()'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";
- }
-
-
- BBBBUUUUGGGGSSSS
- There is no way to make find or finddepth follow symlinks.
