PWAIT(1)                    General Commands Manual                   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.

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.
