>>Using FAQ #7896, by Ramon F. Jaquez, I can now find out which user has opened a certain file. Now, I would like to know which user have it open exclusive and which shared - but I don't see such an option in this download. Is it possible to get this information?

Sure. But: In my system, there is apparently some rogue process that keeps the file open exclusively, and I don't know which process it is, or which user is using it. So the question is not, did someone use it exclusively, but rather, who. I hope this will help me track down the error.
FAQ #7896 tells me who is using some file, but not, whether it is exclusive.
