Perl One-Liners: 130 Programs That Get Things Done

By Peteris Krumins
Published November 2013 by No Starch Press.

Perl one-liners are small and awesome Perl programs that fit in one line of code and do one thing really well, 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. Author Peteris Krumins' dissections of each bit of code will help you gain a deeper understanding of the Perl language, and these Perl one-liners are sure to save you time and sharpen your sleight of hand.
