List of DOS commands Wikipedia. This article presents a list of commands used by DOSoperating systems, especially as used on x. IBM PC compatibles PCs. Other DOS operating systems are not part of the scope of this list. In DOS, many standard system commands were provided for common tasks such as listing files on a disk or moving files. Some commands were built into the command interpreter, others existed as external commands on disk. Over the several generations of DOS, commands were added for the additional functions of the operating system. In the current Microsoft Windows operating system, a text mode command prompt window, cmd. Command processingeditThe command interpreter for DOS runs when no application programs are running.

Some commands are internal built into COMMAND. COM others are external commands stored on disk. When the user types a line of text at the operating system command prompt, COMMAND. COM will parse the line and attempt to match a command name to a built in command or to the name of an executable program file or batch file on disk. If no match is found, an error message is printed, and the command prompt is refreshed.

Such utility programs would be stored on disk and loaded just like regular application programs but were distributed with the operating system. Copies of these utility command programs had to be on an accessible disk, either on the current drive or on the command path set in the command interpreter. In the list below, commands that can accept more than one file name, or a filename including wildcards and , are said to accept a filespec file specification parameter. Commands that can accept only a single file name are said to accept a filename parameter. Additionally, command line switches, or other parameter strings, can be supplied on the command line. Spaces and symbols such as a or a may be used to allow the command processor to parse the command line into filenames, file specifications, and other options. The command interpreter preserves the case of whatever parameters are passed to commands, but the command names themselves and file names are case insensitive.

DOS commandseditA partial list of the most common commands for MS DOS follows below. 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 filename extension. The command redirects requests for disk operations on one drive to a different drive. It can also display drive assignments or reset all drive letters to their original assignments.

For detailed instructions on the below. AMD has just released its fastest processor yet after more than a half decade of research and development, and Intels Kaby Lake processor is now available in every. The novelty of summer is wearing off, and were spending more time in the nice airconditioned indoors. That means more time for catching up on Netflix. Weve. The command is available in MS DOS 5. Attrib changes or views the attributes of one or more files. It defaults to displaying the attributes of all files in the current directory. The file attributes available include read only, archive, system, and hidden attributes. The command has the capability to process whole folders and subfolders of files,BACKUP and RESTOREeditThese are commands to backup and restore files from an external disk. These appeared in version 2, and continued to PC DOS 5 and MS DOS 6 PC DOS 7 had a deversioned check. In DOS 6, these were replaced by commercial programs CPBACKUP, MSBACKUP, which allowed files to be restored to different locations. BASIC and BASICAeditAn implementation of the BASIC programming language for PCs. Implementing BASIC in this way was very common in operating systems on 8 and 1. IBM computers had BASIC 1. ROM, and IBMs versions of BASIC used code in this ROM BASIC, which allowed for extra memory in the code area. BASICA last appeared in IBM PC DOS 5. OS2 2. 0 and later, the version had ROM BASIC moved into the program code. Microsoft released GW BASIC for machines with no ROM BASIC. Some OEM releases had basic. GW BASIC. EXE. BASIC was dropped after MS DOS 4, and PC DOS 5. OS2 which uses PC DOS 5, has it, while MS DOS 5 does not. Starts a batch file from within another batch file and returns when that one ends. CD and CHDIReditThe CHDIR or the alternative name CD command either displays or changes the current working directory. The command either displays or changes the active code page used to display character glyphs in a console window. CHKDSK verifies a storage volume for example, a hard disk, disk partition or floppy disk for file system integrity. The command has the ability to fix errors on a volume and recover information from defective disk sectors of a volume. The CHOICE command is used in batch files to prompt the user to select one item from a set of single character choices. Choice was introduced as an external command with MS DOS 6. Add Adobe Pdf Printer Windows 7'>Add Adobe Pdf Printer Windows 7. Novell DOS 72 and PC DOS 7. Earlier versions of DR DOS supported this function with the built in switch command for numeric choices or by beginning a command with a question mark. This command was formerly called ync yes no cancel. The CLS or CLRSCR command clears the terminal screen. Copies files from one location to another. It is used to make copies of existing files. This command can be used to combine multiple files into target files. The destination defaults to the current directory. If multiple source files are indicated, the destination must be a directory, or an error will result. COPY has the ability to concatenate files. The command can copy in text mode or binary mode in text mode, copy will stop when it reaches the EOF character in binary mode, the files will be concatenated in their entirety, ignoring EOF characters. Files may be copied to devices. For example, copy file con outputs file to the screen console. Devices themselves may be copied to a destination file, for example, copy con file takes the text typed into the console and puts it into FILE, stopping when EOF CtrlZ is typed. Defines the terminal device for example, COM1 to use for input and output. Displays the system date and prompts the user to enter a new date. Complements the TIME command. A very primitive assembler and disassambler. The command has the ability to analyze the file fragmentation on a disk drive or to defragment a drive. This command is called DEFRAG in MS DOSPC DOS and diskopt in DR DOS. DEL and ERASEeditDEL or the alternative form ERASE is used to delete one or more files. DELTREEeditDeletes a directory along with all of the files and subdirectories that it contains. Normally, it will ask for confirmation of the potentially dangerous action. We know that the RDRMDIR command can not delete a directory if the directory is not empty. DELTREE command can be used to delete the whole directory if the directory is not empty. The deltree command is included in certain versions of Microsoft Windows and Microsoft DOSOperating Systems. It is specifically available only in versions of MS DOS 6. Microsoft Windows 9x. In Windows NT, the functionality provided exists but is handled by the command rd or rmdir which has slightly different syntax. This command has been deprecated for Windows 7. DELTREEYDRIVE PATH.
