Software :: Script For Checking Ownership / Permissions Of Directory

I am writing a script that is checking the ownership and permissions of a directory. If the directory in question does not have the correct ownership and permissions, the script will run the appropriate commands to give it the correct settings. The if...then...else syntax. The idea here is the following:

Code:
If <directory> no eq = <ownership root:root> && <permissions 755>
then chown root:root <directory> && chmod 755 <directory>
else exit
fi
What would the correct syntax be for the If line of the loop in question?
