In computing, exit is a command used in many operating system command-line shells and scripting languages.. The command causes the shell or program to terminate.If performed within an interactive command shell, the user is logged out of their current session, and/or user's current console or terminal connection is disconnected.
cmd.exe in Windows NT 2000, 4DOS, 4OS2, 4NT, and a number of third-party solutions allow direct entry of environment variables from the command prompt. From at least Windows 2000, the set command allows for the evaluation of strings into variables, thus providing inter alia a means of performing integer arithmetic.
Windows 11 running in safe mode. Microsoft Windows' safe mode (for 7/Vista [1] /XP [2] /2000/ME/98/95 [citation needed]) is accessed by pressing the F8 key as the operating system boots. [3] Also, in a multi-boot environment with multiple versions of Windows installed side by side, the F8 key can be pressed at the OS selector prompt to get to ...
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 ...
On startup, the MS-DOS component in Windows 95 responds to a pressed F8 key by temporarily pausing the default boot process and presenting the DOS boot options menu, allowing the user to continue starting Windows normally, start Windows in safe mode or exit to the DOS prompt. [21]
This recovery prompt is also displayed when the primary command processor is aborted due to faults or if it is exited deliberately. [4] (In the case of COMMAND.COM, the internal EXIT command is disabled only when the shell was started with /P.) This also provides limited means to replace the shell at runtime without having to reboot the system.
In the BIOS keys can have different purposes depending on the BIOS. However, F10 is the de facto standard for save and exit which saves all changes and restarts the system. During Windows 10 startup, ⇧ Shift + F8 is used to enter safe mode; in legacy versions of Microsoft Windows, the F8 key was used alone.
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]
