Hrm. I hadn't thought about that.

Here's what I have:

log () {

export LOG="$HOME/Desktop/$NAME.log.txt"

zmodload zsh/datetime

TIME=$(strftime %Y-%m-%d--%H.%M.%S "$EPOCHSECONDS")

OUTPUT=`$@ 2>&1`

EXIT="$?"

if [[ "$EXIT" != "0" ]]
then

 # failed
echo "$NAME [$TIME]: $@ failed\nOUTPUT: >$OUTPUT<\nExit: >$EXIT<" | tee -a
"$LOG"

exit $EXIT
fi
}


so now I can run

log foo

and have it logged and exit if it necessary.  This seems very useful.

Hrm. Actually, I can add logging of successful commands which have output
as well. Again, very handy.

Anything I can or "should" do differently in the function above?  Always
open to ideas, as I usually find that I don't think of the most efficient
way of doing things, I just find something that works (or seems to) and go
with that :-)

Thanks!
