Command Prompt, also known as cmd.exe or cmd, is the default command-line interpreter for the OS/2, [1] eComStation, ArcaOS, Microsoft Windows (Windows NT family and Windows CE family), and ReactOS [2] operating systems. On Windows CE .NET 4.2, [3] Windows CE 5.0 [4] and Windows Embedded CE 6.0 [5] it is referred to as the Command Processor ...
Some commands are built into the command interpreter; others exist as external commands on disk. Over multiple generations, commands were added for additional functions. In Microsoft Windows, a command prompt window that uses many of the same commands, cmd.exe, can still be used.
COMMAND.COM's successor on OS/2 and Windows NT systems is cmd.exe, although COMMAND.COM is available in virtual DOS machines on IA-32 versions of those operating systems as well. The COMMAND.COM filename was also used by Disk Control Program (DCP), an MS-DOS derivative by the former East German VEB Robotron. [2] COMMAND.COM is a DOS program.
Command.com running in a Windows console on Windows 95 Windows 9x support is relatively poor compared to Windows NT , because the console window runs in the system virtual DOS machine and so keyboard input to a Win32 console application had to be directed to it by conagent.exe running in a DOS VM that are also used for real DOS applications by ...
Command interpreters do not have to give a command prompt, interactive or otherwise. All these need to do is read a batch file, and process the line as commands or as a default action. The default action in say 'cmd.exe' is to look for a file of the same name.
Python 3.0, released in 2008, was a major revision not completely backward-compatible with earlier versions. Python 2.7.18, released in 2020, was the last release of Python 2. [37] Python consistently ranks as one of the most popular programming languages, and has gained widespread use in the machine learning community. [38] [39] [40] [41]
A command-line interface (CLI) is a means of interacting with a computer program by inputting lines of text called command lines. Command-line interfaces emerged in the mid-1960s, on computer terminals, as an interactive and more user-friendly alternative to the non-interactive mode available with punched cards. [1]
In MS-DOS, a batch file can be started from the command-line interface by typing its name, followed by any required parameters and pressing the ↵ Enter key. When DOS loads, the file AUTOEXEC.BAT, when present, is automatically executed, so any commands that need to be run to set up the DOS environment may be placed in this file.
