Answer #2perl is generally more powerful and efficient than shells. It is designed for a different purpose (pattern extraction and reporting, hence its name). Shells are designed both for scripting and for running commands interactively. Shells require many other subcommands (grep, sed, awk, tr, cat, ls, find, etc...) to perform various tasks, whereas perl can do all of this itself, which means it doesn't have to fork() subprocesses. It has advanced data structure support (multi-subscripted arrays, hashes, etc.), which shells generally don't.
I generally do small jobs in shell, medium jobs in awk, and bigger jobs in perl.
