This SO post explains very well how to install command line tools for Xcode 4.4.
But how to uninstall them?
There's a script listed on this page to do just that on Mountain Lion: http://www.cocoanetics.com/2012/07/you-dont-need-the-xcode-command-line-tools/
Copy the script into a text file.
Save it as remove_CLI_tools.sh
Open terminal and navigate to the folder where you saved the script.
Type: sh remove_CLI_tools.sh
I installed just the isolated command line tools (stand alone installer) without installing the Xcode application. So I ended up running the script twice, changing the variables at the top for each of the packages installed by the installer
(you can check which packages were installed by looking in the hidden "Packages" file of the .dmg image of the installer):com.apple.pkg.DeveloperToolsCLI.bom and .plist
com.apple.pkg.DevSDK.bom and .plist
Be careful (have a backup, like the post recommends).
sudo /Developer/Library/uninstall-devtools –mode=all works for 10.8.5
This should still work to remove xcode.
sudo /Developer/Library/uninstall-devtools –mode=all
sudo /Library/Developer/Shared/uninstall-devtools --mode=all
