8 | * The "source" command allows to define "script images", i. e. files |
9 | * that contain command sequences that can be executed by the command | |
10 | * interpreter. It returns the exit status of the last command | |
11 | * executed from the script. This is very similar to running a shell | |
12 | * script in a UNIX shell, hence the name for the command. | |
