As a security and auditing feature, sudo may be configured to log each command run. When a user attempts to invoke sudo without being listed in the configuration file, an exception indication is presented to the user indicating that the attempt has been recorded. If configured, the root user will be alerted via mail. By default, an entry is ...
There is no gksudo option to do the same; however, running sudo -k not within a terminal instance (e.g. through the Alt + F2 "Run Application" dialogue box, unticking "Run in terminal") will have the desired effect. Authenticate does not save passwords. If the user is a standard user, they must enter a username and a password.
The command su, including the Unix permissions system and the setuid system call, was part of Version 1 Unix.Encrypted passwords appeared in Version 3. [5] The command is available as a separate package for Microsoft Windows as part of the UnxUtils collection of native Win32 ports of common GNU Unix-like utilities.

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). [1] [2] [6] Debian and its derivatives create a group called sudo with purpose similar to that of a wheel group. [7]
The command functions more or less like a single-line command-line interface. In the GNOME (a UNIX-like derivative) interface, the Run command is used to run applications via terminal commands. It can be accessed by pressing Alt+F2. KDE (a UNIX-like derivative) has similar functionality called KRunner. It is accessible via the same key binds.
This poses a security risk that led to the development of UAC. Users can set a process to run with elevated privileges from standard accounts by setting the process to "run as administrator" or using the runas command and authenticating the prompt with credentials (username and password) of an administrator account. Much of the benefit of ...
