You've already got plenty of good advice in this thread, but I thought
you might be interested in seeing just how short the program can be if
you use a lot of Perl's features.
#!/usr/bin/perl
use strict;
use warnings;
@ARGV = '/etc/passwd';
print sort { (split /:/, $a)[2] <=> (split /:/, $b)[2] } <>;
I probably wouldn't use something _quite_ this cryptic in production code.
Cheers,
