User information script
Hi Guys,

I just started learning unix and was wondering if anyone can assist me with my User info script.The script file lets the user input their personal information (Their name, address, phone number etc...). The script will then ask the user to input the info again if the input is incorrect or not given. This is what I entered so far :

Finished=f
while [ "$Finished" = f ]
do
tput cup 6 9; echo -n "Enter your phone number: "; read phone
while [ "$phone" = "<not sure how to set this up>" ]; do
echo "Please enter your phone number: "; read phone
done


My question is how do I setup my while loop so that if the user enters his phone number in the wrong format it will prompt him to enter the phone number correctly ?

Thanks very much for the assistance
