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.
--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, 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. For other processes, it may be necessary
to use the KILL (9) signal, since this signal cannot be caught. If the
KILL (9) signal is sent, the exit status is 128+9 rather than 124.
BUGS
Some platforms don't curently support timeouts beyond 2038
