NAME
       timeout - run a command with a time limit

SYNOPSIS
       timeout [OPTION] DURATION COMMAND [ARG]...
       timeout [OPTION]

DESCRIPTION
       Start COMMAND, and kill it if still running after DURATION.

       Mandatory arguments to long options are mandatory for short options too.

       --preserve-status

	      exit with the same status as COMMAND, even when the

	      command times out

       --foreground

	      when not running timeout directly from a shell prompt,

	      allow  COMMAND  to read from the TTY and get TTY signals; in this mode, children of
	      COMMAND will not be timed out

       -k, --kill-after=DURATION

	      also send a KILL signal if COMMAND is still running

	      this long after the initial signal was sent

       -s, --signal=SIGNAL

	      specify the signal to be sent on timeout;

	      SIGNAL may be a name like 'HUP' or a number; see 'kill -l' for a list of signals

       --help
	      display this help and exit

       --version
	      output version information and exit

       DURATION is a floating point  number  with  an  optional  suffix:  's'  for  seconds  (the
       default), 'm' for minutes, 'h' for hours or 'd' for days.

       If  the	command  times	out, and --preserve-status is not set, then exit with status 124.
       Otherwise, exit with the status of COMMAND.  If no signal is specified, send the TERM sig-
       nal  upon  timeout.   The  TERM signal kills any process that does not block or catch that
       signal.	It may be necessary to use the KILL (9)  signal,  since  this  signal  cannot  be
       caught, in which case the exit status is 128+9 rather than 124.
