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.
