lsof command
we can use losf for this problem .if using this command we can find out whoever opened the wich files also we can find based on the username and login anme etc..
eg:
lsof -c names -u ^user
the above command used for show the files are opened by processess whose names startes with "names", but exclude those whose owner is the user "user".
we can have more options in lsof command (-t,nl,-u,-c..etc)
