Hi,

I have one question. My home directory of my unix account is open for everyone. If other account copy my files to their directory, is there a way that I can find out who did it. Does the system administrator have some kind of events logs to find out? Thank you so much!

Let's say that a user named joe copied your files to his directory. The system administrator could look in all directories and find that joe has a copy.

What if he has already deleted it? Thanks

Two possibilities.
1) All UNIX files have attribute 'last accessed'. But this field will not tell who/for what the file has been accessed.

2) In our company it works lik this. All the commands run by the employee, as part of his work or other, are stored in a file and the same is sent to the employee's manager for his review/ to track the employee. So if something like this is being done in your company you can find out with the help of SA.
