Exit is required before calling whoami in lab5

[behzadnj]

When you run "sudo su - [email protected]", the user gets switched to vsda. Documentation states that the "root" account should be shown after running "whoami" command. Additionally "rm /etc/sudoers.d/minions" will fail since we are still using vsda account.

"""
[root@ip-172-31-19-115 ~]# sudo su - [email protected]
Creating home directory for [email protected].
[[email protected]@ip-172-31-19-115 ~]$ rm /etc/sudoers.d/minions
rm: cannot remove '/etc/sudoers.d/minions': Permission denied
"""

This can be solved by adding "exit" before removing minions:

[root@ip-172-31-19-115 ~]# sudo su - [email protected]

[[email protected]@ip-172-31-19-115 ~]$ exit
logout
[root@ip-172-31-19-115 ~]# rm /etc/sudoers.d/minions
rm: remove regular file '/etc/sudoers.d/minions'? y
[root@ip-172-31-19-115 ~]# whoami
