| 1 | # Usage: |
| 2 | # require "finddepth.pl"; |
| 3 | # |
| 4 | # &finddepth('/foo','/bar'); |
| 5 | # |
| 6 | # sub wanted { ... } |
| 7 | # where wanted does whatever you want. $dir contains the |
| 8 | # current directory name, and $_ the current filename within |
| 9 | # that directory. $name contains "$dir/$_". You are cd'ed |
| 10 | # to $dir when the function is called. The function may |
| 11 | # set $prune to prune the tree. |
| 12 | # |
| 13 | # This library is primarily for find2perl, which, when fed |
| 14 | # |
| 15 | # find2perl / -name .nfs\* -mtime +7 -exec rm -f {} \; -o -fstype nfs -prune |
| 16 | # |
| 17 | # spits out something like this |
| 18 | # |
| 19 | # sub wanted { |
| 20 | # /^\.nfs.*$/ && |
| 21 | # (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_)) && |
| 22 | # int(-M _) > 7 && |
| 23 | # unlink($_) |
| 24 | # || |
| 25 | # ($nlink || (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_))) && |
| 26 | # $dev < 0 && |
| 27 | # ($prune = 1); |
| 28 | # } |
