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
              receive 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 2038
