It's a question on something I'm working on for my Linux Class. Problem is, I can't seem to find any help on this whatever online or in my book.

We have four options to pick which is command line expanion. However, I can't seem to figure it out.

a. echo Your file was processed on ‘date +%m/%d/%y’
b. echo Your file has been processed
c. echo \;
d. cp file /tmp


Could someone tell me the correct choice, and WHY? I'd like to know what command line expansion means. I'm quite surprised I can't find this anywhere.

ps -> this isn't cheating. It's a take home for a reason. He said to use any resources we want. As I've mentioned, I've looked around quite a bit, but I can't figure it out. Hopefully someone here might be able to clue me in.

I found it here.

Do you perhaps mean "shell expansion"?
Here is the first hit in a Google search using "shell expansion":

This doc, BTW, is one of the best begineers books I have seen....
