When you push the wrong key in Linux, it beeps.. it even beeps sometimes when you press the right key.. If you get irritated, just run this script with a parameter 'off' or 'on' (I think it'll only work under the bash shell)
#!/bin/sh
if [ "$1" = "off" ]; then
echo -e "\33[11;0]"
echo "Bell turned off."
fi
if [ "$1" = "on" ]; then
echo -e "\33[10;750]\33[11;250]"
echo "Bell turned on."
fi
if [ "$1" = "" ]; then
echo "Usage: $0 <on|off>"
fi
