Ok Here are some hint commands that I know could help you with :

1) addrecord;;
read name
read title
... etc etc
date="$name:$title ...."
cat $data >> /path/to/phonebook

2) showall;;
cat /path/to/phonebook

3) searchrecord;;
read tosearch
grep $tosearch /path/to/phonebook

4) delete;;
read tosearch
grep -v $tosearch /path/to/phonebook > /path/to/phonebook.tmp
cat /path/to/phonebook.tmp > /path/to/phonebook

5) edit
I dont know what does this mean

I guess you got the idea ...
