[HDGEM] Regular expressions are powerful tools for selecting particular lines from files or output.

A lot of UNIX commands use regular expressions: vimperl, the PostgreSQL database and so on. They can be made available in any language or application using external libraries, and they even found their way to non-UNIX systems. For instance, regular expressions are used in the Excell spreadsheet that comes with the MicroSoft Windows Office suite.
