Debian script should take expected outcome into account

[jbjonesjr]

Currently, the script just does the audit activity. ex:
dpkg -s aide

The expected outcome is installed ok installed

I propose that the script should take this outcomes into consideration where possible, and provide the audit result.

Something like:

if [ `dpkg -s aide` = "installed ok installed" ]; then
  echo "Audit passed"
else
  echo "Audit failed"
fi
