Thanks, Scott:

I already knew that I didn't have permission!

I don't understand equating files to integers.

I got as follows.
{
-rw-r----- 1 root shadow 1271 Sep 2 19:16 /etc/shadow
-r--r----- 1 root root 755 Jan 18 2018 /etc/sudoers
}

My permissions list looks the same as yours. Though the integers before
the dates are different.

Yes, I used visudo.

> Defaults mail_badpass
> Defaults

> %sudo ALL=(ALL:ALL) ALL
That file is locked; I lack permission to view it.
