So, I made this code, but it's not working and I have no idea why.
Code:
#!/bin/sh
read VAR < /dev/input/event3
if [ -n "${VAR}" ]; then
echo "Key pressed"
else
echo "No key pressed"
fi
If I do something like 'cat /dev/input/event3' and press some keys, I get all sorts of garbage on the screen, so I know I can get output from the keyboard, but when I run the script '$VAR' stays empty. If I use a regular non-empty file or some other device, (like the hard disk) the script works.
I'm totally stumped. Any help would be much appreciated.
