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.

       Upon timeout, send the TERM signal to COMMAND, if no other  SIGNAL  specified.   The  TERM
       signal kills any process that does not block or catch that signal.  It may be necessary to
       use the KILL signal, since this signal can't be caught.

   Exit status:
       124    if COMMAND times out, and --preserve-status is not specified

       125    if the timeout command itself fails

       126    if COMMAND is found but cannot be invoked

       127    if COMMAND cannot be found

       137    if COMMAND (or timeout itself) is sent the KILL (9) signal (128+9)

       -      the exit status of COMMAND otherwise

BUGS

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