Redirections are processed in the order they appear on the command line. So "2>&1 >logfile" redirects stderr to the same as current stdout (normally the terminal) and then redirects stdout to logfile. You need to swap the two redirections to send both streams to logfile. grep > 2>&1 logfile Sorry does not work (syntax error near unexpected token '2'). O.
