Loop help...
Hi, I'm starting to learn about shell scripts. The following is my basic script... Code:
echo "Please enter your first name: \c" read firstname echo "Please enter your last name: \c" read lastname echo "Your name is $firstname $lastname. Is that correct?" select BOOLEAN in Yes No do if [[ -z "$BOOLEAN" ]] then echo "Incorrect choice. Choose again!" else echo "Welcome $firstname $lastname" break fi done My problem is that when it comes to the choosing 'Yes' or 'No', if I select NO, the code will continue as if I selected YES. However, if I select NO, I want the code to keep asking the user to retype their name until they say YES. Can someone help me? Thanks. |
