sed (stream editor) is a Unix utility that parses text and implements a programming language which can apply transformations to such text. It reads input line by line (sequentially), applying the operation which has been specified via the command line (or a sed script), and then outputs the line. It was developed from 1973 to 1974 as a Unix utility by Lee E. McMahon of Bell Labs, and is available today for most operating systems.

The sovereign ghost. As such, the Socrates
Of snails, musician of pears, principium
And lex. Sed quæritur: is this same wig
Of things, this nincompated pedagogue,
Preceptor to the sea?”
