Controlling command execution

The SmartWare command shell includes a basic set of commands that allow you to control the execution of
other running commands. In SmartWare the commands jobs and fg are used for such purposes. The command
jobs lists all running commands, and fg allows switching back a suspended command to the foreground. More-
over using Ctrl-Z suspends an active command and lets the system prompt reappear. With Ctrl-C the cur-
rently active command can be terminated.
Mode: Administrator execution
