General syntax:

exit:unknown ()

This function enqueues a request to shut down the SystemTap session. It does not unwind the current probe handler, nor block new probe handlers. The stap daemon will respond to the request and initiate an ordered shutdown.

General syntax:

system (cmd:string)

This function runs a command on the system. The command will run in the background when the current probe completes.
