What's the difference between this and the bash '&&' operator? Except for the timebomb flag, I don't really see any difference. Please correct me if I got this wrong. The '&&' operator, as in which ruby && echo 'found it!', triggers the second command, if the exit code of the first one is 0. Also good to note, the '||' operator triggers the second command only if the exit code of the first one is different than 0. As in which ruby123456 || echo 'could not find it!'. EDIT: typo.
