Alias (command)alias is a shellcommand that defines a word that the shell replaces with associated text before interpreting a command line. It is often used to enhance productivity by abbreviating a command or for including commonly used arguments with a command. The command is available in Unix shells, AmigaDOS, 4DOS/4NT, FreeDOS, KolibriOS, PowerShell, ReactOS, EFI shell, and IBM i. Aliasing functionality in MS-DOS and Command Prompt is provided by the DOSKEY command.
PowerShellCross-platform shell based on .NET technologyPowerShell is a shellprogram developed by Microsoft for task automation and configuration management. As is typical for a shell, it provides a command-lineinterpreter for interactive use and a script interpreter for automation via a language defined for it. Originally only for Windows, known as Windows PowerShell, it was made open-source and cross-platform on August 18, 2016, with the introduction of PowerShell Core.Take Command ConsoleTake Command Console (TCC), formerly known as 4DOS for Windows NT (4NT), is a command-line interpreter by JP Software, designed as a substitute for the default command interpreter in Microsoft Windows, CMD.EXE. Take Command was the name that JP Software used for their GUI command-line interpreters for Windows 3.1 (TC16), Windows 32-bit (TC32) and later OS/2Presentation Manager (TCOS2). These were released concurrently with version 4DOS 5.5, 4NT 2.5 and 4OS2 2.52.
Shell (computing)An operating systemshell is a computer program that provides relatively broad and direct access to the system on which it runs. The term shell refers to how it is a relatively thin layer around an operating system. Most shells are command-line interface (CLI) programs. Some graphical user interfaces (GUI) also include shells.
COMMAND.COMCOMMAND.COM is the default command-line interpreter for MS-DOS, Windows 95, Windows 98 and Windows Me. In the case of DOS, it is the default user interface as well. It has an additional role as the usual first program run after boot (init process). As a shell, COMMAND.COM has two distinct modes of operation: interactive mode and batch mode.
4DOS4DOS is a command-line interpreter by JP Software, designed to replace the default command interpreter COMMAND.COM in MS-DOS and Windows. It was written by Rex C. Conn and Tom Rawson and first released in 1989. Compared to the default, it has a large number of enhancements. 4OS2 and 4NT are similar products that replace cmd.exe in OS/2 and Windows NT respectively.
Directory (computing)In computing, a directory is a file system cataloging structure that contains references to other computer files, and possibly other directories. On many computers, directories are known as folders or drawers, analogous to a workbench or the traditional office filing cabinet. The name derives from books like a telephone directory that lists the phone numbers of all the people living in a certain area. Files are organized by storing related files in the same directory.
Command (computing)In computing, a command is a high-level instruction received via an external interface that directs the behavior of a computer program. Commonly, commands are sent to a program via a command-line interface, a script, a network protocol, or as an event triggered in a graphical user interface. Many commands support arguments to specify input and to modify default behavior. Terminology and syntax varies but there are notable common approaches.
Operating systemSoftware that manages computer hardware resourcesAn operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and other resources.Computer fileA computer file is a named collection of data treated as a unit by the system that manages it. Today, this system is called a file system. Many older computer systems lacked a distinct file system per se, yet a management feature is required in order to provide a file abstraction. Files can be shared with and transferred between computers and mobile devices via removable media, networks, or the Internet. Different types of computer files are designed for different purposes.Cmd.execmd.exe, also known as Command Prompt or Windows Command Processor, is a shell program on later versions of Windows (NT and CE families), OS/2, eComStation, ArcaOS, and ReactOS. In some versions of Windows (CE .NET 4.2, CE 5.0 and Embedded CE 6.0) it is referred to as the Command Processor Shell. Implementation differs between operating systems, but with significant consistency of behavior and available commands.*As an Amazon Associate I earn from qualifying purchases.
