Grep is a command line utility originally created for the [[Unix]] operating system. It searches files for a word or pattern of characters.
Its input is a list of files (or current directory by default) and a text string or set of [[regular expressions]]. Its output consists of lines of text in the given files that match the string or [[regular expressions]]. The name "grep" stands for "Global Regular Expression Parser."
Grep is one of the most popular [[Unix]] utilities, and has been copied by many other operating systems.
