Questions tagged [perl]
Perl is a language optimized for scanning arbitrary text files, extracting information from those text files, and printing reports based on that information. It's also a good language for many system management tasks. The CPAN is Perl's module repository and is where users should turn first for code that implements solutions to already-solved problems.
