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]
After authentication, and if the configuration file permits the user access, the system invokes the requested command. sudo retains the user's invocation rights through a grace period (typically 5 minutes) per pseudo terminal, allowing the user to execute several successive commands as the requested user without having to provide a password again.
In some cases, the actual name of the account is not the determining factor; on Unix-like systems, for example, the user with a user identifier (UID) of zero is the superuser [i.e., uid=0], regardless of the name of that account; [1] and in systems which implement a role-based security model, any user with the role of superuser (or its synonyms ...
sudo centralizes all privilege authorization information in a single configuration file, /etc/sudoers, which contains a list of users and the privileged applications and actions that those users are permitted to use. The grammar of the sudoers file is intended to be flexible enough to cover many different scenarios, such as placing restrictions ...
In this mode users can assume the user environment of the target user. john@localhost:~$ su - jane Password: jane@localhost:~$ The command sudo is related, and executes a command as another user but observes a set of constraints about which users can execute which commands as which other users (generally in a configuration file named /etc ...
The local host administrators can create and install manual pages associated with the specific host. A manual end user may invoke a documentation page by issuing the man command followed by the specific detail they require. These manual pages are typically requested by end users, programmers and administrators doing real time work but can also ...
The package should also work under all other Debian derived distributions (e.g. Ubuntu, don't forget the sudo command). For other distributions, extract the truetype font and place it under either /usr/share/fonts/ (with superuser right) or ~/.fonts/ (normal user right). Then run the following command to refresh font cache: fc-cache -v
Debian-based operating system —Debian is a Unix-like computer operating system that is composed entirely of free software, most of which is under the GNU General Public License and packaged by a group of individuals participating in the Debian Project. Debian has many derivatives, among which Ubuntu is the most popular.
