1. The problem statement, all variables and given/known data:
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.

2. Relevant commands, code, scripts, algorithms:

3. The attempts at a solution (include all code and scripts):

#!/bin/bash
name=$1
if [ “$name” = “” ]
then echo -n “Name ‘xyz’ not in directory”
read name
fi
grep -i cheryl ~uli101/uli101/phonebook
grep -i $name ~uli101/uli101/phonebook
