how to detect a user who changed a particular file in Linux.

Hi all,

(Note : I'm writing this mail to this kernel group as I did not find any
suitable mechanism in application level for my below need).

If a  file modified by some user then how can we detect that user who
modified it.

Linux audit was not suitable for my need.

Can this be achieved through kernel driver/module.

Any other suggestions/help would be welcome.

Thanks in advance.

Regards,
Ravikumar.
