1.6. Enabling a Software Collection

Remember that:

• When you run the scl tool, it creates a child process (subshell) of the current shell. Running the command again then creates a subshell of the subshell.
• You can list enabled Software Collections for the current subshell. See Section 1.7, “Listing Enabled Software Collections” for more information.
• You have to disable an enabled Software Collection first to be able to enable it again. To disable the Software Collection, exit the subshell created when enabling the Software Collections.
• When using the scl tool to enable a Software Collection, you can only perform one action with the enabled Software Collection at a time. The enabled Software Collection must be disabled first before performing another action.
