AT&T Corp., originally the American Telephone and Telegraph Company, is the subsidiary of AT&T that provides voice, video, data, and Internet telecommunications and professional services to businesses, consumers, and government agencies.
Berkeley Software Distribution (BSD) was a Unix operating system derivative developed and distributed by the Computer Systems Research Group (CSRG) of the University of California, Berkeley, from 1977 to 1995.
The chgrp (from change group) command may be used by unprivileged users on Unix-like systems to change the group associated with a file system object (such as a file, directory, or link) to one of which they are a member.
The command chown, an abbreviation of change owner, is used on Unix-like systems to change the owner of file system files, directories.
Computing is any goal-oriented activity requiring, benefiting from, or creating computers.
In computing, dir (directory) is a command used for file and directory listing, specifically in the command line interface (CLI) of the operating systems CP/M, DOS, OS/2, Singularity, Microsoft Windows and in the DCL command line interface used on VMS, RT-11 and RSX-11.
In computing, a directory is a file system cataloging structure which contains references to other computer files, and possibly other directories.
du (abbreviated from disk usage) is a standard Unix program used to estimate file space usage—space used under a particular directory or files on a file system.
Free software or libre software is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions.
FreeBSD is a free and open-source Unix-like operating system descended from Research Unix via the Berkeley Software Distribution (BSD).
GNU is an operating system and an extensive collection of computer software.
The GNU Core Utilities or coreutils is a package of GNU software containing reimplementations for many of the basic tools, such as cat, ls, and rm, which are used on Unix-like operating systems.
In Unix-like systems, multiple users can be put into groups.
In computing, a hard link is a directory entry that associates a name with a file on a file system.
In computing, a hidden folder (sometimes hidden directory) or hidden file is a folder or file which filesystem utilities do not display by default when showing a directory listing.
This is a list of Unix commands as specified by IEEE Std 1003.1-2008, which is part of the Single UNIX Specification (SUS).
Multics (Multiplexed Information and Computing Service) is an influential early time-sharing operating system, based around the concept of a single-level memory.
The open-source model is a decentralized software-development model that encourages open collaboration.
The Portable Operating System Interface (POSIX) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems.
The Single UNIX Specification (SUS) is the collective name of a family of standards for computer operating systems, compliance with which is required to qualify for using the "UNIX" trademark.
Spotlight is a system-wide desktop search feature of Apple's macOS and iOS operating systems.
Termcap (terminal capability) is a software library and database used on Unix-like computers.
Unix (trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, development starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
For normal files in the file system, Unix does not impose or provide any internal file structure.
In Unix and operating systems inspired by it, the file system is considered a central component of the operating system.
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, while not necessarily conforming to or being certified to any version of the Single UNIX Specification.
Unix-like operating systems identify a user within the kernel by a value called a user identifier, often abbreviated to user ID or UID.
In computing, the working directory of a process is a directory of a hierarchical file system, if any, dynamically associated with each process.
