How to check for an error if executing a shell command e.g. with system('commandhere')?

< ^ > P N |<>|^_>< --- | ~ ...Help

Hi,
I'm writing a little script to install some drivers but I wanna react in this script if any step fails. So e.g. I'm doing this:
  system('dpkg -i xorg-driver-fglrx fglrx-kernel-source')
How can I check if this was succesful or if there was any error?
