sudo (super user do)#

On Unix-like operating systems, the sudo command is used to run commands with the root user's privileges. This is done by entering sudo at the beginning of each line of commands. Alternatively, one may become root (system administrator) by logging in as "root" or by using the su command. Becoming root requires root's password. In contrast, the sudo command asks for the user's password and does not depend on the root user account.

Sudo - Generally pronounced IPA: (sudu), is a program for Unix-like operating systems such as BSD, Mac OS X, and Linux that allows users to run programs with the security privileges of another user (normally the system's superuser) in a secure manner. By default it is installed in /usr/bin. sudo was originally written by Bob Coggeshall and Cliff Spencer around 1980 at the Department of Computer Science at SUNY/Buffalo. The current version is maintained by OpenBSD developer Todd C Miller and distributed under a BSD-style license.
