Awk
From Conservapedia
Awk is an interpretive program for text and data processing, which is typically provided on UNIX systems. It is known both for its conciseness and its power.
It was developed at Bell Laboratories in the 1970s by Alfred Aho, Peter Weinberger, and Brian Kernighan, whose initials provided its name. It was an improvement on "sed", a predecessor text and data processing program also available with the UNIX operating system.
