timeout

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.

-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 an integer 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.
