lib/perl5/5.6.1/find.pl

   1 # Usage:
   2 #       require "find.pl";
   3 #
   4 #       &find('/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 #       }
  29 #
  30 # Set the variable $dont_use_nlink if you're using AFS, since AFS cheats.
