PWAIT(1) |
NAME
pwait — wait for processes to terminate
SYNOPSIS
pwait |
[-isv] [-t timeout] pid ... |
DESCRIPTION
The
pwait utility will wait until each of the given processes has terminated.
The following option is available:
-
-i
-
Don't wait for all the processes, exit after the first process or group of processes exit.
-
-s
-
Exit with the status code of the first non-zero exit status pid, or if timed out exit with 255.
-
-t timeout
-
Only wait for timeout seconds before exiting.
-
-v
-
Print the exit status when each process terminates.
DIAGNOSTICS
The
pwait utility returns 0 on success, and >0 if an error occurs.
Invalid pids elicit a warning message but are otherwise ignored.
NOTES
pwait is not a substitute for the
wait(1) builtin as it will not clean up any zombies or state in the parent process.
HISTORY
A pwait command first appeared in SunOS 5.8.
