Problem
1. How do you link foo1 to foo2 using
(i) a hard link,
(ii) a symbolic link? If you delete foo1, does it make any difference?
2. Copy the file /etc/passwd to your current directory and then observe the listing of the copy. Which attributes have changed?
3. Where are the UID and GID of a file stored?
4. How is chown different from chgrp on a BSD-based system when it comes to renouncing ownership?
