TIMEOUT(1) User Commands TIMEOUT(1) 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. --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 -v, --verbose diagnose to stderr any signal sent upon timeout --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. 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 sig- nal 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. BUGS Some platforms don't currently support timeouts beyond the year 2038. AUTHOR Written by Padraig Brady.
