Is there a way to have a command that does not show up in history? Or a

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.
In bash, If I prepend the command with a space character, it does not show
up in the ~/.bash_history file.
This happens if in .bashrc you set the shell variable HISTCONTROL to
include the value "ignorespace". See man bash
example:
HISTCONTROL=ignoredups:ignorespace
