sigpause [ -cdbu sig -an ] [ prog ]where prog is one or more arguments specifying a program to run.
Options are:
-c sig: Catch sig and unblock during pause.
-d sig: Set default action for sig and unblock during pause.
-b sig: Block sig during pause.
-u sig: Unblock sig during pause.
-a sig: Block all signals during pause.
-n sig: Block no signals during pause.
After processing options, sigpause pauses waiting for unblocked signals. A caught signal causes sigpause to execute prog, or exit 0 in the absence of prog.
