Debian's which hunt

Agreed. I dimmly remembered my instructor in the late 1980's telling me about the differences (and hidden horrors) between csh and sh so that we could write scripts on our SunOS systems witch would also work on our new HP-UX box. Reading this sparked a bunch of 'ooooh yeah.' and why we quickly moved all our systems to use tcsh to get edited history.
