Su (Unix)

The Unix command .mw-parser-output .monospaced{font-family:monospace,monospace}su, which stands for "substitute user" (or historically "superuser"), 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.
