The Read Statement in Linux

We will provide a simple example of the “read” statement showing how you can interact with an end-user. Note, that in this example we are not handling errors, since we want to keep it simple. Let’s create the read.sh script.

echo "Enter your First Name: "
read FIRSTNAME
echo "Enter your Last Name: "
read LASTNAME

echo ""
echo "Your Full Name is $FIRSTNAME $LASTNAME"

echo ""
echo "Enter your Age: "
read AGE

echo "Next year, you will be `expr $AGE + 1` years old."

Let’s run it now.

Note how we wrote the expression using the backticks expr $AGE + 1
