loops?

hello....very new user to unix...and i have a question..i am not sure if there is such a thing


For example...the user is asked if he likes Bananas....if he says yes....

echo You like Bananas $name
at the end of the script it echos all that the user has entered so they can read it....
but if the user if the user says no it still comes ou

you like bananas $name

is there a loop structure so that if they put no then at the end the script it will say they dont like bananas....I am not sure if you will understand this but I dont know how else to explain it...
Thanks!!

Well, if I understand what you are asking, there are actually several ways to do this...
Code:
#!/bin/sh
negative=""
echo "Do you like bananas?"
read banana
case $banana in
     Y*|y*) negative="" ;;
     N*|n*) negative="do not " ;;
            *) echo "Huh?" ; exit 1 ;;
esac
echo "You said you ${negative}like bananas"
exit 0

That is persoanlly how I would do it.
Like I said though, there are several ways to do it.

I sure hope that wasn't homework...
