grep (version 2.5.1a)
Grep searches the named input FILEs (or standard input if no files are named, or the file name - is given) for lines con- taining a match to the given PATTERN. By default, grep prints the matching lines.
In addition, two variant programs egrep and fgrep are avail- able. Egrep is the same as grep -E. Fgrep is the same as grep -F.
