GREP(1)                                General Commands Manual                                GREP(1)

NAME
       grep, egrep, fgrep - print lines matching a pattern

SYNOPSIS
       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.

egrep is the same as
       grep -E.  fgrep is the same as grep -F.
