Note: Most of this was written 20 years ago and much of it may be out of date. OTOH, the nice thing
about Unix is what you learned 50 years ago is probably still usable today.
This page is a collection of tips and tricks that I've learned over
the years. I put them here mostly for my own purposes. I tend
to learn something, figure out something, or read about something, and
think "That's pretty nifty" but then not use it for six months. By
that point I've forgotten the particulars, and then have to waste hours
looking through web pages, as most of these things don't seem to exist
in a condensed form in any books or web pages (or maybe it's just me).
