Hi Shawn,

Is there a way to have a command that does not show up in history? Or a
way to pipe a string where the string doesn't show up in history?
Ie, I set some passwords with:
echo "some string and stuff" ¦ sha512sum
(Probably with cut and awk and other such things)
And I'd like a way for my system to not store my password scheme. I'd
prefer something better than editing my history file.
Something like this will work:
# echo |sha512sum <<EOF
> $(echo fred smith was here|awk '{print $2,$4}')

Testing it works as expected (the sha512sum value that is) ...
# echo smith here|sha512sum

With the EOF exampls, "history" only stores the first line. This is
different to using line continuation.
