I'm afraid I dont understand how the '.*' will capture a space within the second column, seeing it's followed by a '\s+'?

Another thing, that had just occured to me:

The letter present in the third column is identical to one of the letters(first or second) in the second column.

So if I checked that, I'd know if a space turned up in the wrong place, because the letters don't check out right?

So you ran the code, saw that it works, but didn't know why.

I would suggest perldoc perlre or perhaps The Owl Book. It works because I have anchored it at both ends ^ and $ and forced the other spaces where appropriate. Since general use of .* is frowned upon, I have modified it after reading your more constraining information here.
