I have a good awk book on my site that may be of some help.
Awk is an awesome and an extermely powerful language.

Ok,

The site gave me some light to see how I can make this work.

Just one thing can you give me an example of how I can run a program that
asked the user for input to sort the items?

nawk is more robust than awk and has some functions like readline etc.
You could also use shell for user interaction and pass the variable into
the awk script - just a crude example:
Code:
echo "Phonelist"
echo "------------------"
echo "1) Firstname"
echo "2) Lastname"
echo "etc...\n"
echo "How would you like to sort the list? \c"
read SORTVAL
echo $SORTVAL

awk '
        BEGIN { print $sval
        }
{
        if (sval == 1) print "Will sort by Firstname"
        if (sval == 2) print "Will sort by Lastname"

}' sval=$SORTVAL phonebook
