Okay, I know almost all of those.  Never used ci or co before, nor gpg
(blasphemy! - but I intend to).  I tend to think that you left out "tr" and
"cut".  They're quite useful.

grep, grep -v, tr, cut and a redirection symbol ">" can be quite powerful in
a shell script.

Otherwise, it's gravy.  I'm clueless about awk and [for the most part]
worthless with sed, so I think those will be my new focal points.

Uhhh, what?





Thanks for all the tips!
