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.
