How about the following:
ilsefe2:~$ /usr/ucb/ps -aux|head -1
USER PID %CPU %MEM SZ RSS TT S START TIME COMMAND
Broken Pipe
ilsefe2:~$ /usr/ucb/ps -aux|grep mathijs

It doesn't use any extra extra programs, nor the somewhat deprecated /usr/ucb/ps
command. The only problem I see may be the alignment of some fields. The ps
command itself is listed because the user mathijs was running it...
