"Minimal Perl" by Tim Maher is unrivaled for this.

Thank you for mentioning that book - I'm very interested in how perl can replace awk and sed and even grep(!) - I use grep multiple times a day, awk maybe a few times a week, and sed very rarely. I think I'm in the target demographic for this :)

The book constains Perl one-liner-style equivalents of these UNIX utilities which you can just drop into your bin directory.

Cool, I'm in the market for that.

For Perl-style grep there's also ack and it's successor ag which you might want to look at first.
