in thread search folder and delete certain files with perl

Because it is so much more compact:

use Modern::Perl; use File::Find::Rule; my $directory = '/var/opt/xim/syslogs/'; my $age = time - 12*60*60; unlink for File::Find::Rule->file() ->name('Syslogd*') ->mtime("<$age") ->maxdepth( 1 ) ->in($directory);

    Maybe slightly, I could have compacted my example quite a bit. But I personally prefer doing at least simple things on my own rather than relying on a black box that may or may not work as intended. Maybe this is an extremely reliable module that everyone uses, but how do I know?
      You can never be certain, but verily I say, I have made more errors in home brewn code than in code I loaded from CPAN.

        Well, for complex tasks I do prefer modules.
      Why bother with a module when stat is available?

      Also because CountZero's example is more legible which makes it more elegant and more maintainable. I have to focus my attention more to read your code, and I would have to consult perldoc -f stat if I had any trouble with remembering what the hell falls at [9]; which I would. Positional arguments/values are good for computers but my human brain tunes out after two of them.

      Try it and exercise good judgement. Read the numerous five star reviews of it on CPAN ratings. See how often it's been used in answers here by beautiful and talented monkses.
