Seems there are plenty of Mac admins that want to retrieve the current screen resolution in a script. This is a quick-and-dirty program that will do just that.

Example output:

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>Screens</key>
	<array>
		<dict>
			<key>Name</key>
			<string>iMac</string>
			<key>Resolution</key>
			<string>1920x1080</string>
			<key>ResolutionSansDockAndMenu</key>
			<string>1920x1000</string>
		</dict>
		<dict>
