Hi again djt !!
Try this one, this idea addresses the RH-side of the equation, namely: ranges of values:
Code:
read character
case $character in
# Check for letters
[a-z] | [A-Z] ) echo "Alpha range i[a-z]: You typed the letter $character"
;;
# Check for digits
[0-9] ) echo "Numeric range: 0-9: You typed the digit $character"
;;
# Check for anything else
* ) echo "You did not type a letter or a digit"
esac
