grep: Invoking

 
 2 Invoking ‘grep’
 *****************
 
 The general synopsis of the ‘grep’ command line is
 
      grep [OPTION...] [PATTERNS] [FILE...]
 
 There can be zero or more OPTION arguments, and zero or more FILE
 arguments.  The PATTERNS argument contains one or more patterns
 separated by newlines, and is omitted when patterns are given via the
 ‘-e PATTERNS’ or ‘-f FILE’ options.  Typically PATTERNS should be quoted
 when ‘grep’ is used in a shell command.
