The sigpause program

Usage

where prog is one or more arguments specifying a program to run.

Description

Each option that takes a signal as its argument accepts either a number or one of the (case insensitive) strings ALRM, CHLD, CONT, HUP, INT, PIPE, or TERM.

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.
