Actually, you're all being duped!!! In truth I'm teaching an Intro to Unix
course at WSU. I will periodically post questions like this (things I do and
don't know the answer to). I then cut and paste the responses I get and show
them to the class. We teach on (Debian) Linux and I'm trying to get the
students used to "getting on-line" the open-source, Linux, collaborative
way. Also ACLUG gets a plug. Sometimes I do have questions of my own, so
please don't be angry at my suberfuge.
