oshalla and eight-one gave good descriptions of the grep block

The code almost works. Here are a couple of mods to make things work

  • The variable $file requires a my declaration
  • 'mv' is not a native perl function, use rename file1, file2. You could also use system() but, on my computer, that function seemed to work a little slower
  • You need to put double quotes around the second file otherwise perl interprets the '.' as the concatenation operator
  • Here is the modified code

    #! /usr/local/bin/perl use strict; use warnings; use diagnostics; die unless chdir "/path/directory"; die unless opendir DIR, '.'; foreach my $file (grep {-f && (14 < -M)} readdir DIR) { # print $file,"\n"; rename $file, ".$file"; # system("mv", $file, ".$file"); } closedir DIR;

    use strict; use warnings; use diagnostics;
