Perl's usefulness extends all the way to work done directly at the prompt. In addition to its many run-mode flags, there is available a Perl shell (psh) which endows some of Perl's features to your command-line. We'll talk about psh as well as the prompt tools kit - a collection of handy Perl scripts for munging data at the prompt. The kit includes tools like extract (modeled after grep, but tests specific fields of a line), col (modeled after cut, but allows you to swap, roll, and delete columns), histogram/collapse (used for data reduction), sums/stats (basic descriptive statistics), and others.
