sudo (/ s uː d uː / [4]) is a program for Unix-like computer operating systems that enables users to run programs with the security privileges of another user, by default the superuser. [5] It originally stood for "superuser do", [ 6 ] as that was all it did, and this remains its most common usage; [ 7 ] however, the official Sudo project ...
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 ...
A filesystem ACL is a data structure (usually a table) containing entries that specify individual user or group rights to specific system objects such as programs, processes, or files. These entries are known as access-control entries (ACEs) in the Microsoft Windows NT, [4] OpenVMS, and Unix-like operating systems such as Linux, macOS, and ...
It is also possible to use polkit to execute commands with elevated privileges using the command pkexec followed by the command intended to be executed (with root permission). [9] However, it may be preferable to use sudo, as this command provides more flexibility and security, in addition to being easier to configure. [10]
Windows Subsystem for Linux GUI (WSLg) is built with the purpose of enabling support for running Linux GUI applications (X11 and Wayland) on Windows in a fully integrated desktop experience. [34] WSLg was officially released at the Microsoft Build 2021 conference and is included in Windows 10 Insider build 21364 or later. [ 20 ]
Sudo command on Ubuntu to temporarily assume root privileges. Most Unix and Unix-like systems have an account or group which enables a user to exact complete control over the system, often known as a root account. If access to this account is gained by an unwanted user, this results in a complete breach of the system.
A privilege is applied for by either an executed program issuing a request for advanced privileges, or by running some program to apply for the additional privileges. An example of a user applying for additional privileges is provided by the sudo command to run a command as superuser ( root ) user, or by the Kerberos authentication system.
Linux portal; Linux (and other Unix-like systems) have a multi-tier security that permits user root any system-wide changes. Regular users can be limited: where they can save files, what hardware they can access, their memory usage, applications, disk usage (), and the range of priority settings they can apply, can all be specified to provide sufficient freedoms.
