PWAIT(1) General Commands Manual PWAIT(1)

NAME

pwaitwait 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.
