Shell Script to Check Vowels

Linux script allows the user to use the case command that accepts the input from the user and match the answer. To elaborate this we are asking the question Enter any vowel and the script will accept the answer in both upper case and lower case.

vi vowel_check.sh

# !bin/bash

echo Enter any vowel?
read response
case $response in
A) echo $response is correct ;;
a) echo $response is correct ;;
E) echo $response is correct ;;
e) echo $response is correct ;;
I) echo $response is correct ;;
i) echo $response is correct ;;
O) echo $response is correct ;;
o) echo $response is correct ;;
U) echo $response is correct ;;
u) echo $response is correct ;;
*) echo sorry, that is wrong
esac

Here is the sample output of the above script
