How can I know which of the /dev/input/eventX (X=0..7) have the Linux input stream?

Question

I am trying to capture linux keyboard/mouse input, and I am reading events from like /dev/input/event2. But it seems the input are sometimes directed to /dev/

Answer 1

Run this in Terminal, it will work just fine:

cat /proc/bus/input/devices | awk '/keyboard/{for(a=0;a>=0;a++){getline;{if(/kbd/==1){ print 
$NF;exit 0;}}}}'
