--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 betimed out

-k

also send a KILL signal if COMMAND is still runningthis long after the initial signal was sent

-s

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 exitDURATION 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 withthe status of COMMAND. If no signal is specified, send the TERM signal upon timeout. The TERM signal killsany process that does not block or catch that signal. It may be necessary to use the KILL (9) signal, sincethis signal cannot be caught, in which case the exit status is 128+9 rather than 124.BUGSSome platforms don't currently support timeouts beyond the year 2038.AUTHORWritten by Padraig Brady.REPORTING BUGSGNU coreutils online help: <http://www.gnu.org/software/coreutils/>Report timeout translation bugs to <http://translationproject.org/team/>COPYRIGHTCopyright © 2017 Free Software Foundation, Inc.
