The grep command searches one or more input files for lines containing a match to a specified pattern. By default, grep prints the matching lines.
The current stable version of grep can be found on in the subdirectory /gnu/grep/ on your favorite GNU mirror.
The current development version (introducing new features and bugfixes, but also quite possibly new bugs) can be accessed using CVS. Detailed instructions can be found here.
