Perl one-liners are programs that fit in one line of code and do one thing really well. Peteris Krumins showcases 130 lines of code that do all sorts of handy, geeky things like numbering lines in a file; generating random passwords; encoding, decoding, and converting strings; calculating factorials; even checking to see if a number is prime with a regular expression.
