Let me explain it. There is no need in rpm -aq and grep if you can do only rpm -q PACKAGE_NAME. So rpm will do grep for you.

This is the more elegant answer than the accepted one. The return value from rpm -q is all you need. Funnily, -qa doesn't return the same return codes, so you need to redirect stdout to /dev/null and stick with -q.
