timeout komutu

-k seçeneği
Örnek
Açıklaması şöyle.

evtest is run with a timeout of 10 seconds, and additional grace period of 5 seconds in (unlikely) case it hangs, after which it's killed by SIGKILL, hopefully returning keyboard control to you.

Şöyle yaparız.

sudo su -c 'sleep 1; timeout -k5 10 evtest --grab /dev/input/event18'
