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