I don't get what you are doing with the sub function, from reading up on sub it looks like you are changing any space on the end of a line to an x from what I can see. How does this work?Smilie
Ah of course the value of x not the character x, thanks Smilie

Correcting my own code (no sub is needed):

Code:
awk 'NF { r = r ? r $0 : $0 }
/:END:/ { print r; r = x }' infile

Great everyone!

radoulov, this worked fine to clean out the lines as from what I see now Smilie
Code:
awk 'NF { r = r ? r $0 : $0 }
/:END:/ { print r; r = x }' infile

Thanks everyone for the support, I was really appreciated your help.

See you around.

I think it should be there radoulov. Otherwise there is no separating space between lines and if you use
Code:
r" "$0

then sometimes there are two spaces.

I assumed that every newline between ^@: and :END: should be removed.
I was not sure if it had to be substituted with a space.
But you're right - for example, given the sample data, be long should be separate words.
