N00B Bash script question

[Zionsv]

Hello, I have a question regarding a bash script.

#ask for first name and assign to firstName
echo -e "\nWhat is your First name? "
read firstName

I would like to add and if statement like this

if [firstName == ""]
then
echo -e "\nPlease enter a name."

My question is how do I come out of the if statement and back to the "what is your name?"

Sorry if this is unclear or if the syntax isn't correct. I only have a small amount of coding knowledge and its Java...

Thanks in advance!!

You might want to use a while loop:

firstname=""
while [ "$firstname" == "" ]; do
        echo -ne "\nWhat is your First name? "
        read firstname
        if [ "$firstname" == "" ]; then
                echo "Please enter name."
        fi
done

        if [ "$firstname" == "" ]; then
                echo "Please enter name."
        fi
done

Ah of course! Now that I see it, it seems so simple. I guess that's the way it goes when you're learning though. Thanks!!

Absolutly, and of course as with most programming there are lots of ways to get things done....
