You'll need to install proctools. MacPorts and Fink have this if you're running Mac OS X, check your Linux distribution's repositories if it isn't installed by default.

There are 6 alternatives - vote for the best!

Pipes the header row of ps to STDERR, then greps for the command on the output of ps, removing the grep entry before that.

psgrep() { if [ ! -z $1 ] ; then echo "Grepping for processes matching $1..." ps aux | grep -i $1 | grep -v grep else echo "!! Need name to grep for" fi }
