ack - 3.7.0-1 main

Ack is designed as an alternative for 99% of the uses of grep. ack is
intelligent about the files it searches. It knows about certain file
types, based on both the extension on the file and, in some cases, the
contents of the file.
.
Ack ignores backup files and files under CVS and .svn directories. It
also highlights matches to help you see where the match was. Ack uses
perl regular expressions.
