TIMEOUT(1) User Commands TIMEOUT(1)NAMEtimeout - run a command with a time limit
SYNOPSIStimeout [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 receive 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
--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.
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
