There are two user A & B. sharing same server. A has created a directory with permission 700 and both user and group are same i.e. user A
drwx --- --- A A temp_dir/
Now user B has permission to access A's files. What B did is, he moved this "temp_dir/" to his home directory.
Now this moved directory has the same permission before i.e. 700 with user and group is A.
When B is trying to access the files from this directory he is not able to do it.
He is not able to change the permission neither he has sudo/root user permission.
How B can access this directory?
