1.8. Uninstalling a Software Collection

You can use conventional tools like Yum or PackageKit when uninstalling a Software Collection because Software Collections are fully compatible with the RPM Package Manager. For example, to uninstall all packages and subpackages that are part of a Software Collection named software_collection_1, run the following command:
 yum remove software_collection_1\* 
You can also use the yum remove command to remove the scl utility.
For detailed information on Yum and PackageKit usage, see the Red Hat Enterprise Linux 7 System Administrator's Guide, or the Red Hat Enterprise Linux 6 Deployment Guide.
