The first meeting of Unix users took place in New York in 1974, attracting a few dozen people; this would later grow into the USENIX organization. The importance of the user group stemmed from the fact that Unix was entirely unsupported by AT&T. [8]
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. The password file maps textual user names to UIDs.
The finger program was written in 1971 by Les Earnest who created the program to solve the need of users who wanted information on other users of the network. Information on who is logged in was useful to check the availability of a person to meet. This was probably the earliest form of presence information for remote network users.
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.

Unix (/ ˈ j uː n ɪ k s / ⓘ, YOO-niks; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 [1] at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. [4]

The server message is used to tell a server that the other end of a new connection is a server. [36] This message is also used to pass server data over the whole network. <hopcount> details how many hops (server connections) away <servername> is. <info> contains addition human-readable information about the server.
