Add another grep to the command line, perhaps? Like this:
# ps aux | grep processname | grep -v grep
Excerpt from the manual entry for grep:
---------------------------
-v, --invert-match
Invert the sense of matching, to select non-matching lines.
---------------------------
So adding "grep -v grep" will go through that already grepped list and
return the lines that *don't* contain the process for grep.
