Answer Description
Placing sudo (SuperUser Do) in front of a command in some Linux environments will run the command with the security privileges of the root account. Once the command finishes the privileges will be removed and are not applied to any further commands or applications. (unless they are also run with sudo)

sudo ( or ) is a program for Unix-like computer operating systems that allows users to run programs with the security privileges of another user, by default the superuser It originally stood for "superuser do" as the older versions of sudo were designed to run commands only as the superuser However, the later versions added support for running commands not only as the superuser but also as other (restricted) users, and thus it is also commonly expanded as "substitute user do" Although the latter case reflects its current functionality more accurately, sudo is still often called "superuser do" since it is so often used for administrative tasks
