In the sed command there is a saved substring "\(.*\)" wich we want and is recalled with "\1".
After this pattern we have "\..*" wich means a dot and everything after it.
Sed uses a greedy match (AKA longest match) so the saved substring will contain the part before the last "." in the substring.

Actually, the echo is quite useless, too.

Code:
FNAME=${FILE_NAME%.*}
