Try running 'phone4 xyz' and see what happens.

Modify your program so that if no matching name is found, an appropriate message is displayed: "Name 'xyz' not in directory".

You could use an 'if' statement to check the value of $? to see if the grep command was successful (remember, '0' indicates success).

If the grep is NOT successful, then echo the message (which includes the value of $name).Give it a try.

Make sure this works with both command line arguments and with a name read in from the user, and make sure you use the message

EXACTLY as shown.
