sudo (/ s uː d uː / [4]) is a program for Unix-like computer operating systems that enables users to run programs with the security privileges of another user, by default the superuser.

In computing, runas (a compound word, from “run as”) is a command in the Microsoft Windows line of operating systems that allows a user to run specific tools and programs under a different username to the one that was used to logon to a computer interactively. [1]
The Unix command su, which stands for 'substitute user' [1] [2] (or historically 'superuser' [3] [4]), is used by a computer user to execute commands with the privileges of another user account. When executed it invokes a shell without changing the current working directory or the user environment.
The remote shell (rsh) is a command-line computer program that can execute shell commands as another user, and on another computer across a computer network. The remote system to which rsh connects runs the rsh daemon (rshd). The daemon typically uses the well-known Transmission Control Protocol (TCP) port number 513.
Modern Unix systems generally use user groups as a security protocol to control access privileges. The wheel group is a special user group used on some Unix systems, mostly BSD systems, [citation needed] to control access to the su [4] [5] or sudo command, which allows a user to masquerade as another user (usually the super user).
This is a list of POSIX (Portable Operating System Interface) commands as specified by IEEE Std 1003.1-2024, which is part of the Single UNIX Specification (SUS). These commands can be found on Unix operating systems and most Unix-like operating systems.
