Hello,

I have a file ( sas or not sas file). it is open or used by an others users.

Guess that would be done on OS level via a Unix command. What's going to work will depend on your environment. Good thing is: There is heaps of information & discussions around this on the Internet. Just two links:

How can I determine what process has a file open in Linux? - Super User
