sudo

Sudo is a program for Unix-like systems that allows users to run programs with the security privileges of another user–typically a user with a higher level of access such as the superuser/root account.

Sudo derives its name from “su” command (which allows users to execute commands as another user by supplying that user’s password) and the word “do”. Sudo is a convenient way for users to run an application or make system changes with temporarily elevated privileges, while otherwise continuing to work within an account with lower over all administrative privileges.
