Task: Using the latest ubuntu distro

1. Change the ownership of directory /opt/resources/change_me so that it is owned by user robert and group marketing. These changes should be applied recursively to /opt/resources/ change_me

2. Add only the SUID bit to the existing permissions on file /opt/answers/list.txt

3. Remove file /opt/answers/remove_me.dat

4. Change the permissions on file /opt/answers/perm_0002.txt so that the owner can read, write and execute, the group can read and execute, and world has no permissions.

5. Add an ACL to /opt/answers/acl_abcd.txt that grants user jimmy write-access to the file.
