I have been checking out a pre-release set of software (GNU) and which uses a function in a shell script to determine whether or not the 'echo' command supports the '-e' flag (on FreeBSD it doesn't). To cut a long story short try the following :- (echo -e) | sed s/-e/xe/ | grep xe; echo $? here sed returns 'xe' and therefore should satisfy a match with 'grep' and should return '0' but it returns a '1' (no match ?). I think this is a 'bug' anyone agree ?? PLEASE REPLY DIRECTLY TO MY MAIL ADDRESS AS I AM NO LONGER REGISTERED WITH THE FORUM. Malcolm G. Boff Sylmex Ltd Malcolm_Boff@compuserve.com
