Trapping an exit status

How could I trap the exit status of grep. The possible exit statuses are 0,1,2. When I'm writing a shell script and executing grep. how can I store these values into a variable?

Well nevermind, I figured it out. There is a builtin variable that catches returned exit statues. Its $? just for future reference.

So if you were just interested in the return code of grep, did you just redirect the STDOUT to /dev/null ??

Yup actually I did redirect it out /dev/null
