Unix file types, the Glossary

The seven standard Unix file types are regular, directory, symbolic link, FIFO special, block special, character special, and socket as defined by POSIX.^[1]

Unix file system technology

Ar (Unix)

The archiver, also known simply as ar, is a Unix utility that maintains groups of files as a single archive file.

See Unix file types and Ar (Unix)

A bit field is a data structure that maps to one or more adjacent bits which have been allocated for specific purposes, so that any single bit or group of bits within the structure can be set or inspected.

See Unix file types and Bit field

Bit numbering

In computing, bit numbering is the convention used to identify the bit positions in a binary number.

See Unix file types and Bit numbering

Computer file

In computing, a computer file is a resource for recording data on a computer storage device, primarily identified by its filename.

See Unix file types and Computer file

Device file

In Unix-like operating systems, a device file, device node, or special file is an interface to a device driver that appears in a file system as if it were an ordinary file. Unix file types and device file are Unix file system technology.

See Unix file types and Device file

Disk partitioning

Disk partitioning or disk slicing is the creation of one or more regions on secondary storage, so that each region can be managed separately.

See Unix file types and Disk partitioning

Doors (computing)

Doors is an inter-process communication facility for Unix computer systems.

See Unix file types and Doors (computing)

Duplex (telecommunications)

A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions.

See Unix file types and Duplex (telecommunications)

File (command)

The file command is a standard program of Unix and Unix-like operating systems for recognizing the type of data contained in a computer file.

See Unix file types and File (command)

File descriptor

In Unix and Unix-like computer operating systems, a file descriptor (FD, less frequently fildes) is a process-unique identifier (handle) for a file or other input/output resource, such as a pipe or network socket. Unix file types and file descriptor are Unix file system technology.

See Unix file types and File descriptor

File format

A file format is a standard way that information is encoded for storage in a computer file.

See Unix file types and File format

File-system permissions

Most file systems include attributes of files and directories that control the ability of users to read, change, navigate, and execute the contents of the file system.

See Unix file types and File-system permissions

Git

Git is a distributed version control system that tracks versions of files.

See Unix file types and Git

Glibc

The GNU C Library, commonly known as glibc, is the GNU Project implementation of the C standard library.

See Unix file types and Glibc

GNU Core Utilities

The GNU Core Utilities or coreutils is a package of GNU software containing implementations for many of the basic tools, such as cat, ls, and rm, which are used on Unix-like operating systems.

See Unix file types and GNU Core Utilities

Gnulib

Gnulib, also called the GNU portability library, is a collection of software subroutines which are designed to be usable on many operating systems.

See Unix file types and Gnulib

Inter-process communication

In computer science, inter-process communication (IPC), also spelled interprocess communication, are the mechanisms provided by an operating system for processes to manage shared data.

See Unix file types and Inter-process communication

Ls

In computing, ls is a command to list computer files and directories in Unix and Unix-like operating systems.

See Unix file types and Ls

Named pipe

In computing, a named pipe (also known as a FIFO for its behavior) is an extension to the traditional pipe concept on Unix and Unix-like systems, and is one of the methods of inter-process communication (IPC).

See Unix file types and Named pipe

Null device

In some operating systems, the null device is a device file that discards all data written to it but reports that the write operation succeeded. Unix file types and null device are Unix file system technology.

See Unix file types and Null device

POSIX

The Portable Operating System Interface (POSIX) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems.

See Unix file types and POSIX

Process (computing)

In computing, a process is the instance of a computer program that is being executed by one or many threads.

See Unix file types and Process (computing)

Stat (system call)

is a Unix system call that returns file attributes about an inode.

See Unix file types and Stat (system call)

Tar (computing)

In computing, tar is a computer software utility for collecting many files into one archive file, often referred to as a tarball, for distribution or backup purposes.

See Unix file types and Tar (computing)

The Open Group

The Open Group is a global consortium that seeks to "enable the achievement of business objectives" by developing "open, vendor-neutral technology standards and certifications." It has 900+ member organizations and provides a number of services, including strategy, management, innovation and research, standards, certification, and test development.

See Unix file types and The Open Group

Unix

Unix (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 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
