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  signal 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.

BUGS

   Some platforms don't curently support timeouts beyond the year 2038.
