Hello kazazza

AWK need a mapping in order to read normal shell variables, you'd rather need to re-form your command as below to get the desired result:

title="Mr"
echo "Please Enter your name: "
read name
echo $name | awk -v awk_title=$title '{print "hello " awk_title ". " $NF}'

or you can assign the title variable from within AWK
echo "Please Enter your name: "
read name
echo $name | awk BEGIN '{title="Mr"} {print "Hello " title ". " $NF}'
