I admit you have got half a point there.

But manual pages which arent gonna help me all that much are pretty useless.

Probably true. Man pages generally are reference documents, which assume you already know how things work. For newbie's they can be pretty useless.
On the other hand, those web-links I posted, are step-by-step guides. Very readable. After working seriously through those, you know much more about bash than you need for this assignment. Similar doc's exist for e.g. awk.

Problem is if i do what i just wrote ill get a file with about 8 lines all saying customer number 1 through to customer number 8. A direct problem would be how do i seperate each of these into single variables to search for in my vehicle file.

OK. I'll help you get going with that part (I feel a little bad. And helping with some perticular issue should OK)

sorry if i sound rude, just feel a bit humiliated

I'm sorry about that.
It irritates me when people ask questions like "This is my homework", and then expect people here to help them cheat at school/college. If they don't want to learn programming, that's their choice. People here generally like to help other people
learn something, but doing their homework is the
opposite (then they learn nothing) and wasting my time. At least that's how I feel.
But when you got stuck, it's of course OK to ask here. But in that case there will be posted some code, or at least some
specific question. I feel people having a question, could at least takes some time actually ask some specific question. Just: "This is my homewerk, PLEASE HELP!!!" doesn't cut it.
I guess, your question was somewhere in the middle. And I may have been a little harsh on you in my first reply.
I'll shut up and go and hide in a cave. Sorry once again
Now for the next bit of my homework, just kidding
