sed

sed is a utility that transforms text via a script written in a relatively simple and compact programming language. It was developed from 1973 to 1974 by Lee E. McMahon of Bell Labs, and is available today for most operating systems. The functionality of sed is based on the scripting features of the interactive editor ed and the earlier qed. It was one of the earliest tools to support regular expressions, and remains in use for text processing, most notably with the substitution command. Popular alternative tools for text manipulation and stream editing include AWK and Perl. The shell command that runs the utility has the same name: sed. Wikipedia
