"SUDO Teach Me a Lesson"
The command “sudo” is an essential part of Vax, Unix, and Linux operating systems. It’s so intrinsic to how SysAdmins work, many consider “sudo” to be a built-in command and are shocked when they encounter a system where it’s missing. Since its introduction in 1980, it’s been used millions of times a day, on millions of systems, by millions of users around the world.
