Dear all,

I have an input file with a list of movies (Note that there might be some repeated entries):

American_beauty__1h56mn38s_
As_Good_As_It_Gets
As_Good_As_It_Gets
_DivX-ITA__Casablanca_M_CURTIZ_1942_Bogart-bergman_
Capote_EN_DVDRiP_XViD-GeT-AW
_DivX-ITA__Casablanca_M_CURTIZ_1942_Bogart-bergman_

I would to find the corresponding match (line number) from another reference file for each of the entries in the first file:

American beauty.(1h56mn38s)
As Good As It Gets
Capote.EN.DVDRiP.XViD-GeT-AW
[DivX-ITA] Casablanca(M.CURTIZ 1942 Bogart-bergman)
Quills (2000)(7.4)

The desired output would be something like (Reference Movie + Line number from the Reference File):

American beauty.(1h56mn38s) 1
As Good As It Gets 2
As Good As It Gets 2
[DivX-ITA] Casablanca(M.CURTIZ 1942 Bogart-bergman) 4
Capote.EN.DVDRiP.XViD-GeT-AW 3
[DivX-ITA] Casablanca(M.CURTIZ 1942 Bogart-bergman) 4

Basically, the difference between the entries in both files is that some characters such as: blank spaces, parenthesis, points, etc. have been replaced by underscores.

Does anybody could shed some light on it?

Best wishes,

Javier
