Not always going to work. For example,
[ste...@scs:~]% ps ax | grep init
1 ? Ss 0:39 init [2]
13421 pts/1 R+ 0:00 grep init
This is why you should use pgrep(1) to find a PID (and kill it) rather
than directly grepping a ps output like the previous poster did.
Yes, pgrep is the tool. If you already know the pid, you can
use good old ps:
ps 1 && echo init runs
