Sudoedit is a program that symlinks to the sudo binary. It prevents multiple simultaneous edits with locks and performs sanity and syntax checks. Visudo is a command-line utility that allows editing the sudo configuration file in a fail-safe manner. In association with SELinux, sudo can be used to transition between roles in role-based access control (RBAC). This allows for more secure logging of admin commands and prevents some exploits. In some system distributions, sudo has largely supplanted the default use of a distinct superuser login for administrative tasks, most notably in some Linux distributions as well as Apple's macOS. The program may be configured to require a password. The /etc/sudoers file contains a list of users or user groups with permission to execute a subset of commands while having the privileges of the root user or another specified user. By default, an entry is recorded in the system. If configured, the root user will be alerted via mail. 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.

SUDO MEANING SLANG PASSWORD

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.Īs a security and auditing feature, sudo may be configured to log each command run. After authentication, and if the configuration file permits the user access, the system invokes the requested command. This allows authorized users to exercise altered privileges without compromising the secrecy of the other account's password. Unlike the command su, users supply their personal password to sudo (if necessary) rather than that of the superuser or other account.

Miller since 1994, and has been distributed under an ISC-style license since 1999. The current version has been publicly maintained by OpenBSD developer Todd C.

SUDO MEANING SLANG CODE

Between 19, the code and features were substantially modified by the IT staff of the University of Colorado Boulder Computer Science Department and the College of Engineering and Applied Science, including Todd C. Robert Coggeshall brought sudo with him to the University of Colorado Boulder. Robert Coggeshall and Cliff Spencer wrote the original subsystem around 1980 at the Department of Computer Science at SUNY/Buffalo.

It can also be configured to permit passing arguments or multiple commands. The configuration file offers detailed access permissions, including enabling commands only from the invoking terminal requiring a password per user or group requiring re-entry of a password every time or never requiring a password at all for a particular command line. After authentication, and if the configuration file (typically /etc/sudoers) permits the user access, the system invokes the requested command.

Unlike the similar command su, users must, by default, supply their own password for authentication, rather than the password of the target user.

SUDO MEANING SLANG MANUAL

The current Linux manual pages for su define it as "substitute user", making the correct meaning of sudo "substitute user, do", because sudo can run a command as other users as well. It originally stood for "superuser do", as that was all it did, and it is its most common usage however, the official Sudo project page lists it as "su 'do' ".

Sudo ( / s uː d uː/ or / ˈ s uː d oʊ/ ) 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.
