запустить команду с ограничением по времени (run a command with a time limit)
Имя (Name)
timeout - run a command with a time limit
Синопсис (Synopsis)
timeout [OPTION] DURATION COMMAND [ARG]...
timeout [OPTION]
Описание (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 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.
Ошибки (баги) (Bugs)
Some platforms don't currently support timeouts beyond the year
2038.
