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
--foreground
-k, --kill-after=DURATION
-s, --signal=SIGNAL
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.
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 currently support timeouts beyond the year 2038.
