Is this homework?
Have a look at

Code:

man uniq

That will provide you with most of the solution.

Yes it is a old one, that I cant seem to get right. I have read the man and uniq -u seems good. And I have read all internet and done almost everything with the file. Can do just about everything but get the number of uniq lines?

and if I write -u -c I get the uniqe lines with a number before. but I just want the number.

Ok, I can count the words in the file with wc -w and get a number. Good start! But then I only want the uniq once. Can I pipe wc to uniq or vice vers. I dont know wich order to do it or the way either for that case?

But to get the number of lines is a very good start!

Thank you dear god! I had a error in my test file that was driving me crazy!

Then I used the command: sort -u xxxx.txt | wc -l

Thank you!!!!!!!!!!!

Piping is definitely a core skill that you need to absorb.
Well worth playing around with it for a while until you've got it.

Glad you found your soln in the end.

When really stuck, assume nothing / check everything... we've all been there
