Bad Command Or File Name
"Bad command or file name" is a common and ambiguous error message in MS-DOS. COMMAND.COM produces this error message when the first word of a command could not be interpreted. Because this word must be the name of an internal command, executable file or batch file, the error message provided an accurate description of the problem, but easily confused novices. The wording gave the impression that filenames provided as arguments to the commands were damaged or invalid. Later, the wording of the error message was changed for clarity. Windows NT displays the following error message instead (where "foo" is replaced by the word causing error): Some early Unix shells produced the equally cryptic "foo: no such file or directory" again accurately describing what is wrong but confusing users. Most modern shells produce an error message similar to "foo: command not found". See also *Abort, Retry, Fail? *List of DOS commands This article lists notable commands provided by the MS-DOS di ...

Error Message
An error message is the information displayed when an unforeseen problem occurs, usually on a computer or other device. Modern operating systems with graphical user interfaces, often display error messages using dialog boxes. Error messages are used when user intervention is required, to indicate that a desired operation has failed, or to relay important warnings (such as warning a computer user that they are almost out of hard disk space). Error messages are seen widely throughout computing, and are part of every operating system or computer hardware device. The proper design of error messages is an important topic in usability and other fields of human–computer interaction. Common error messages The following error messages are commonly seen by modern computer users: ;Access denied :This error occurs if the user does not have privileges to a file, or if it has been locked by some program or user. ;Device not ready :This error most often occurs when there is no floppy disk ...

MS-DOS
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax and capabilities. Beginning in 1988 with DR-DOS, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Batch File
A batch file is a Scripting language, script file in DOS, OS/2 and Microsoft Windows. It consists of a series of Command (computing), commands to be executed by the command-line interpreter, stored in a plain text file. A batch file may contain any command the interpreter accepts interactively and use constructs that enable conditional branching and looping within the batch file, such as If statement, IF, Foreach loop, FOR, and GOTO label (computer science), labels. The term "batch" is from batch processing, meaning "non-interactive execution", though a batch file might not process a ''batch'' of multiple data. Similar to Job Control Language (JCL), DIGITAL Command Language, DCL and other systems on mainframe and minicomputer systems, batch files were added to ease the work required for certain regular tasks by allowing the user to set up a script to automate them. When a batch file is run, the Shell (computing), shell program (usually COMMAND.COM or cmd.exe) reads the file and ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MSDN
Microsoft Developer Network (MSDN) was the division of Microsoft responsible for managing the firm's relationship with developers and testers, such as hardware developers interested in the operating system (OS), and software developers developing on the various OS platforms or using the API or scripting languages of Microsoft's applications. The relationship management was situated in assorted media: web sites, newsletters, developer conferences, trade media, blogs and DVD distribution. Starting in January 2020, the website was fully integrated with Microsoft Docs (itself integrated into Microsoft Learn in 2022). Websites MSDN's primary web presence at ''msdn.microsoft.com'' was a collection of sites for the developer community that provided information, documentation, and discussion that was authored both by Microsoft and by the community at large. Microsoft later began placing emphasis on incorporation of forums, blogs, library annotations and social bookmarking to mak ...

Windows NT
Windows NT is a Proprietary software, proprietary Graphical user interface, graphical operating system produced by Microsoft as part of its Windows product line, the first version of which, Windows NT 3.1, was released on July 27, 1993. Originally made for the workstation, office, and Server (computing), server markets, the Windows NT line was made available to consumers with the release of Windows XP in 2001. The underlying technology of Windows NT continues to exist to this day with incremental changes and improvements, with the latest version of Windows based on Windows NT being Windows Server 2025 announced in 2024. The name "Windows NT" originally denoted the major technological advancements that it had introduced to the Windows product line, including eliminating the 16-bit computing, 16-bit memory access limitations of earlier Windows releases such as Windows 3.1 and the Windows 9x series. Each Windows release built on this technology is considered to be based on, if not a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unix Shell
A Unix shell is a Command-line_interface#Command-line_interpreter, command-line interpreter or shell (computing), shell that provides a command line user interface for Unix-like operating systems. The shell is both an interactive command language and a scripting language, and is used by the operating system to control the execution of the system using shell scripts. Users typically interact with a Unix shell using a terminal emulator; however, direct operation via serial hardware connections or Secure Shell are common for server systems. All Unix shells provide filename Wildcard character, wildcarding, Pipeline (Unix), piping, here documents, command substitution, Variable (programming), variables and control flow, control structures for Conditional (programming), condition-testing and iteration. Concept Generally, a ''shell'' is a program that executes other programs in response to text commands. A sophisticated shell can also change the environment in which other programs exe ...

Abort, Retry, Fail?
"Abort, Retry, Fail?" (or "Abort, Retry, Ignore?") is an error message found in DOS operating systems, which Command-line interface#Command prompt, prompts the user (computing), end-user for a course of action to follow. Although an improvement over CP/M, the message has been cited as an example of poor usability in computer user interfaces. Background In CP/M, attempting to read a floppy disk drive with the door open would hang until a disk was inserted and the disk drive door was closed (very early disk hardware did not send any kind of signal until a disk was spinning, and a timeout to detect the lack of signal required too much code on these tiny systems). Many users of CP/M became accustomed to this as a method of managing multiple disks, by opening the disk drive to stop a program from reading or writing a file until the correct disk could be inserted. A primary design consideration for PC DOS was that software written for CP/M be porting, portable to DOS without cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of DOS Commands
This article lists notable commands provided by the MS-DOS disk operating system (DOS), especially as used on an IBM PC compatible computer. Other DOS variants as well as the legacy Windows shell, Command Prompt (cmd.exe), provide many of these commands. Many other DOS variants are informally called ''DOS'', but are not included in the scope of the list. The highly related variant, IBM PC DOS, is included. The list is not intended to be exhaustive, but does include commands covering the various releases. Each command is implemented either as built-in to the command interpreter, COMMAND.COM, or as an external program. Although prevailing style is to write command names in all caps, the interpreter matches ignoring case. Commands APPEND Sets the path to be searched for data files or displays the current search path. The APPEND command is similar to the PATH command that tells DOS where to search for program files (files with a .COM, . EXE, or .BAT file name extension). Th ...
