Hi Brad, I'm not sure about other scripting engines -- But I can certainly think of one very good use: Poling for email :). If you add /var/spool/mail/uname to the select'ed file descriptors, then it would be nice to have a little message line pop up saying "You have new mail". I know this can be done using biff / xbiff / kbiff, etc. But I much prefer a vimbiff :-). GI -- When an actress saw her first strands of gray hair, she thought she'd dye.
