Reversing a Terminal command in Mavericks

Hi there. I have recently upgraded my 2008 MBP to Mavericks. I've been having an issue where the computer won't go to sleep when the lid is shut. After researching the issue and trying a number of 'non-invasive' options, I tried one that was to enter the following into Terminal and then repair my Permissions:

sudo defaults write /System/Library/LaunchDaemons/com.apple.coreservices.appleevents ExitTimeOut -int 1

sudo defaults write /System/Library/LaunchDaemons/com.apple.securityd ExitTimeOut -int 1

sudo defaults write /System/Library/LaunchDaemons/com.apple.mDNSResponder ExitTimeOut -int 1

sudo defaults write /System/Library/LaunchDaemons/com.apple.diskarbitrationd ExitTimeOut -int 1

sudo defaults write /System/Library/LaunchAgents/com.apple.coreservices.appleid.authentication ExitTimeOut -int 1

Unfortunately it did not solve the problem and now one of my programs, "Edgies" will not launch. I'd rather enter in a few quick commands to reverse what's been done instead of re-installing an old backup. Is anyone versed in code enough to help me do this is a couple minutes instead of a few hours!? Thanks for your time.
