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

       -v, --verbose
              diagnose to stderr any signal sent upon timeout

       --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.  A duration of 0 disables the
       associated timeout.

       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 currently support timeouts beyond the year 2038.
