lakeTrout has asked for the wisdom of the Perl Monks concerning the following question:

Hey Monks,
I'm new here and finally have a question that I couldn't find an answer to (a first). Can anyone point me to some resources/documentation/tutorials etc on perl one-liners? I have picked up some things here and there, but would like better explanations on what the options like  -pie, pack and alike do and what they are for.

Thanks,

lakeTrout
