grep, egrep, fgrep – print lines matching a pattern

use:
grep [OPTIONS] PATTERN [FILE…]
grep [OPTIONS] [-e PATTERN | -f FILE] [FILE…]

Description:
grep searches the named input FILEs (or standard input if no files are named, or if a single hyphen-minus (-) is given as file name) for lines containing a match to the given PATTERN. By default, grep prints the matching lines.

In addition, two variant programs egrep and fgrep are available. egrep is the same as grep -E. fgrep is the same as grep -F. Direct invocation as either egrep or fgrep is deprecated, but is provided to allow historical applications that rely on them to run unmodified.
