I tend to write scripts which are tcsh-compatible. So "#!/bin/tcsh". But its somewhat a waste of effort to write one set of scripts for bash and another for tcsh. My main problem is handling the variables. Is there a shell-portable way to specify variables? I write mostly convenience scripts that are generally less than a console screen in length. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
