Suppose i am a user of linux box : A
I also have an access to application account in the box and I
sudo it : B
Somebody else who is a user C also
sudo to: B
Question: When the user C copies or modifies any file say test.txt in a folder say /home/application/ , I need to know who has done it means the original id (C).
When I execute
ls -ltr it shows that the file is created and modified by application account "B". I wanted to know the real user , in this case it wold be "C"
Is there any possibility to know it?
