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 ...
GTK+ Graphical frontend to su and sudo. [7] GKsu comes up automatically when a supported application needs to perform an action requiring root privileges. A replacement, "gksu PolicyKit", which uses PolicyKit rather than su/sudo, is being developed as part of GNOME. [8] kdesu: A Qt graphical front-end to the su command for KDE. [9] kdesudo:
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.
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 authenticating from a standard account is negated if the ...
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.
It may be root's user ID only if ruid, suid, or euid is root. Whenever the euid is changed, the change is propagated to the fsuid . The intent of fsuid is to permit programs (e.g., the NFS server) to limit themselves to the file system rights of some given uid without giving that uid permission to send them signals.
The run-level is usually changed using the init command, runlevel 1 or S will boot into single-user mode. Boot-loader options can be changed during startup before the execution of the kernel. In FreeBSD and DragonFly BSD it can be changed before rebooting the system with the command nextboot -o "-s" -k kernel , and its bootloader offers the ...
Modern Unix systems generally use user groups as a security protocol to control access privileges. 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).
