grep: Invoking

 
 2 Invoking ‘grep’
 *****************
 
 The general synopsis of the ‘grep’ command line is
 
      grep OPTIONS PATTERN INPUT_FILE_NAMES
 
 There can be zero or more OPTIONS.  PATTERN will only be seen as such
 (and not as an INPUT_FILE_NAME) if it wasn’t already specified within
 OPTIONS (by using the ‘-e PATTERN’ or ‘-f FILE’ options).  There can be
 zero or more INPUT_FILE_NAMES.
