    Easy solution:

    #!/bin/bash

read CHAR

[ ${#CHAR} -eq 1 ] && [ $CHAR == 'Y' ] || [ $CHAR == 'y' ] && echo "YES" && exit 0
[ ${#CHAR} -eq 1 ] && [ $CHAR == 'N' ] || [ $CHAR == 'n' ] && echo "NO" && exit 0

    EXPLANATION : : we are reading the char, :next if the char == length 1 we pass that to check if it is y,Y,n,N if it is anyone of it we print and exit

fi
