The Software Collection scriptlets are simple shell scripts that change the current system environment so that the group of packages in the Software Collection is preferred over the corresponding group of conventional packages installed on the system.
A single Software Collection can include multiple Software Collection scriptlets. These scriptlets are located in the
/opt/provider/software_collection/ directory in your Software Collection package. If you only need to distribute a single scriptlet in your Software Collection, it is highly recommended that you use
enable as the name for that scriptlet. When the user runs a command in the Software Collection environment by executing
scl enable software_collection command, the
/opt/provider/software_collection/enable scriptlet is then used to update search paths, and so on.
Note that Software Collection scriptlets can only set the system environment in a subshell that is created by running the
scl enable command. The subshell is only active for the time the command is being performed.
