Mac Terminal Error : Could not determine audit condition

Mac Terminal Error : Could not determine audit condition

When I launched my terminal today, was welcomed with this error :-

login: PAM Error (line 396): System error
login: Could not determine audit condition

[Process completed]

It is most probably because I was playing with my /usr/bin permissions the other day.
The fix is easy. Just delete the "/usr/bin/login" dir.

But how do I delete it, if I can't access the "Terminal" altogether ?
Come on - You can access any folder using the "Finder".

1. Open "Finder"
2. Open "Go To Folder"
3. Type "/usr/bin/login"
4. Delete it.
