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.
