NAME

pwait — wait for processes to terminate

SYNOPSIS

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.

SEE ALSO

kill(1), pkill(1), ps(1), wait(1), kqueue(2)

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.
