A Linux User Group or Linux Users' Group (LUG) or GNU/Linux User Group (GLUG) is a private, generally non-profit or not-for-profit organization that provides support and/or education for Linux users, particularly for inexperienced users. The term commonly refers to local groups that meet in person but is also used to refer to online support ...
In many Unix variants, "nobody" is the conventional name of a user identifier which owns no files, is in no privileged groups, and has no abilities except those which every other user has. It is normally not enabled as a user account, i.e. has no home directory or login credentials assigned. Some systems also define an equivalent group "nogroup".
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]
getent is a Unix command that helps a user get entries in a number of important text files called databases. This includes the passwd and group databases which store user information – hence getent is a common way to look up user details on Unix.
In Unix-like systems, multiple users can be put into groups. POSIX and conventional Unix file system permissions are organized into three classes, user, group, and others.The use of groups allows additional abilities to be delegated in an organized fashion, such as access to disks, printers, and other peripherals.
The Unix and Linux access rights flags setuid and setgid (short for set user identity and set group identity) [1] allow users to run an executable with the file system permissions of the executable's owner or group respectively and to change behaviour in directories. They are often used to allow users on a computer system to run programs with ...
Unix-like operating systems identify a user by a value called a user identifier, often abbreviated to user ID or UID. The UID, along with the group identifier (GID) and other access control criteria, is used to determine which system resources a user can access.
On Internet Relay Chat (IRC), the real name field is sometimes referred to as the gecos field. IRC clients are able to supply this field when connecting. Hexchat, an X-Chat fork, defaults to 'realname', TalkSoup.app on GNUstep defaults to 'David Okeamah', and irssi reads the operating system user's full name, replacing it with 'unknown' if not defined.
