uniq
 

Hi all,

I have a small shell parsing problem:

I have two strings(or I can concatenate them if you like) which in which I only want the unique words.
I tried piping them to uniq -u(only output unique) but that didn't work since uniq sort one lines, not words.

Any idea how to solve this? Perhaps there's a way to convert the string so the words are separeted by lines instead?

Any ideas are appreciated,

cheers,
Frans

If you dont care about the order you can do this:

Thank You!
