TIMEOUT(1)                       User Commands                      TIMEOUT(1)

       timeout - run a command with a time limit

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

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

       Mandatory  arguments  to  long  options are mandatory for short options


              exit with the same status as COMMAND, even when the

              command times out


              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

              display this help and exit

              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 sig-
       nal 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.

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