script to check if process is running
How do I make a shell script to see if a certain process is running.

The process shows up on
Code:
ps aux

as /usr/sbin/daemon

eg:

if [! /usr/sbin/daemon ]
/usr/sbin/daemon
else
#nothin

basically i want to run the process if it isnt running/ has been stopped.

Thanks.

then
     echo Running

fi
