timeout - run a command with a time limit
[OPTION] DURATION COMMAND [ARG]...
Start COMMAND, and kill it if still running after DURATION.
Mandatory arguments to long options are mandatory for short options too.
- also send a KILL signal if COMMAND is still running
this long after the initial signal was sent.
- 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
display this help and exit
output version information and exit
DURATION is an integer with an optional suffix:
`s' for seconds(the default), `m' for minutes, `h' for hours or `d' for days.
If the command times out, 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. For other processes, it may be necessary to
use the KILL (9) signal, since this signal cannot be caught.
