What I do is two things: For commands that I never want to see in my history I make an alias for it that begins with a space character, like so:

  alias mkpwlink=' mkpwlink'

If the shell option histignorespace is set, the mkpwlink command will not appear in the history.

If I want to run a whole "session" of commands without history, I use the history stack:

  HISTSTACK=0
  alias histpush="fc -p && ((HISTSTACK += 1))"
  alias histpop="fc -P && ((HISTSTACK -= 1))"

I use the $HISTSTACK variable in my prompt to keep track of my history level.
