- Run `sleep 10` and kill it, if it's running after 3 seconds:timeout [3s] [sleep 10]- Specify the signal to be sent to the command after the time limit expires. (By default, TERM is sent):timeout --signal [INT] [5s] [sleep 10]
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.
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.
