If you use this: cd foo; blahblah and the directory "foo" does not exist then it will print an error BUT it will still run the command "blahblah". Consider what happens if "blahblah" is really a rm command, for example: cd foo; rm * Now if foo doesn't exist you'll remove all the files in your current directory!! On the other hand, if you use && then the second command only runs if the first one succeeds, so with: cd foo && blahblah the command "blahblah" won't run if the cd fails. -- ------------------------------------------------------------------------------- Paul D.
