Have you heard of case statement?
Do a bit of googling and look around in our forums...

I understand that the case statement will be cleaner, but is this not valid? (e.g. does it accomplish what my teacher wants)?

I tried your master script. It seems to work fine, seems to accomplish what your teacher wants. I did notice (minor nit-picky) that the "echo -e" prints the -e instead of using it as a command option. I won't explain why it does that, according to the forum rules.

I have been trying to replicate this with a case statement because I am not sure which way he wants this. He has an example of creating a menu in our powerpoint slides, so he might want us to do it that way, but I cannot figure out how to add the commands properly. Would it be something like:

# Use of a case statement to offer a 5 item menu
echo �  Menu\n1. Add an entry \n2. Display all matches to a string\n3. Sort and display the file\n4. Delete all entries that match a string\n5. Quit to Unix\nEnter your option #: \c�
read choice
case �$choice� in
	1) add;;
	2) list;;
	3) find;;
	4) delete;;
	5) exit ;;
	*)	echo �Invalid option�   # ;; not needed for last option
esac

I am not sure how to add the commands properly like I did with the original solution, where I included the sub scripts like ./add.sh. Any ideas?

As you said, I think the teacher just wants something that works. You could ask the teacher if case is preferable, or is OK to use if / else.

Cool he said if / else is fine.

Then I would just go with the if / else and move on to the next part of the problem. if / else is more common. vbe is correct that case would be a cleaner choice here, whenever you get around to studying that later.
