MS-DOS or Microsoft Disk Operating System was a 16-bit command user interface operating system used between 1981 and 2000. Following are its features:
- It runs from a disk drive rather than a paper-based medium like a punch card.
- It was a common foundation for all Windows 9x operating systems such as Windows 95, 98, and 98SE.
- The NT kernel completely replaced it in Windows 2000 on the desktop.
- It doesn’t support multimedia.
Is the Command Prompt in our Machine the Same as MS-DOS?
Command prompt is a command-line interpreter available in all Windows operating systems. It is not the same as MS-DOS but an emulator which can run almost all the commands of MS-DOS. Use the following command to get started with the Command Prompt (CMD):
- Press the Windows button to open the start menu.
- Enter CMD.
- Search results will show the command prompt.
How Many Types of DOS Commands Exist?
There are two broad categories of DOS commands as follows:
- Internal Commands : They perform basic operations on files and directories and do not need any external file support.
E.g., CLS, CLEAR
- External Commands : They are for performing advanced tasks and need external file support as they are not stored in COMMAND.COM .
E.g., DISKCOMP, DIR
List of all MS-DOS Commands
Here is a list of all basic MS-DOS commands, along with their syntax and examples.
This command triggers events for MS-DOS to look over other directories during file editing. It gives the user a way to set the search path for the files.
APPEND Drive: \Path /X /E Path:on or off
This command displays/adds/modifies/removes the address resolution protocol information from all the devices.
Syntax: The following syntax is available as taken from PowerShell
Displays current ARP entries by interrogating the current protocol data. If inet_addr is specified, the IP and Physical addresses for only the specified computer are displayed. If more than one network interface uses ARP, entries for each ARP table are displayed.
Same as -a.
Displays current ARP entries in verbose mode. All invalid entries and entries on the loop-back interface will be shown.
Specifies an internet address.
Displays the ARP entries for the network interface specified by if_addr.
Deletes the host specified by inet_addr. inet_addr may be wildcarded with * to delete all hosts.
Adds the host and associates the Internet address inet_addr with the Physical address eth_addr. The Physical address is given as 6 hexadecimal bytes separated by hyphens. The entry is permanent.
Specifies a physical address.
If present, this specifies the Internet address of the interface whose address translation table should be modified. If not present, the first applicable interface will be used.
This command assigns or routes a drive request to a different drive. An assign command with no switches cancels redirected drive assignments and returns them to their original drives.
ASSIGN Source = Target /status
assign c: = b:
This command displays the association of a file related to each different extension available in the machine. Without any parameter, this command displays the current file association.
This command allows the user to schedule a fixed time and date to execute a set of programs.
AT [\\computername] [ [id] [/DELETE] | /DELETE [/YES]]
at 7:00AM "c:\morning.bat"
This will execute morning.bat file at 7:00AM.
This command is now deprecated and now replaced with `schtasks.exe`. If it is run without any parameter, it will show all the scheduled tasks for the future time.
This command allows the user to change the attributes of files. With the help of this command, the user can easily hide/display or do any other change in a file.
ATTRIB [+R | -R] [+A | -A] [+S | -S] [+H | -H] [+O | -O] [+I | -I] [+X | -X] [+P | -P] [+U | -U] [drive:][path][file name] [/S [/D]] [/L]

Work on the attributes of the Symbolic Link versus the target of the Symbolic Link.
Here when we first typed the attrib command, it displayed the A attribute of file.txt. A means archive.
Afterward, we set the read-only attribute to the file and hit the attrib command again. Now it displays A and R
This command enables/disables the keyboard shortcuts for copying and pasting in the command prompt. In other words, Ctrl + C and Ctrl + V.
BREAK [ON | OFF]
It enables the ctrl + C function.
Boot Configuration Datastore Editor. This command modifies the boot configuration data store. It also contains information that is required by the system to boot up.
The content is directly taken from Powershell.
Following are the commands that operate on a store.
|/store||Used to specify a BCD store other than the current system default|
|/createstore||Creates a new and empty boot configuration data store.|

|/sysstore||Sets the system store device (only affects EFI systems, does not persist across reboots, and is only used in cases where the system store device is ambiguous).|

|/copy||Makes copies of entries in the store.|
|/create||Creates new entries in the store.|
|/delete||Deletes entries from the store.|
|/mirror||Creates mirror of entries in the store.|

Before understanding what this command does, we must understand what is an active code page. An active code page is a page which contains character codes and their corresponding characters.
For example, Active code page 437, mostly used in India, contains character code 161 as “b”.
The chcp command helps the user by giving her the option to configure the active code page number. It can be further used to implement the international keyboard allowing DOS to be used in different languages.
This command is the same as the cd command. It is used to change the directory.
chdir windows - It will move to the windows directory (Given that the windows directory should be available in the current directory)
Most of the commands are the same as we use with cd. But as we can see, the last command chdir.. is not running

Most of the DOS commands mentioned above have a screenshot of their execution to help you out more effectively. Although we have tried to mention the syntax of each command, there exist some commands which don’t have any specific syntax. For example, time. Users can just write that command in the command prompt to execute it.
There are possibilities that the commands mentioned above will get updated with a new OS release. If you find any update or have any command in mind, which is essential and not mentioned in the article, then feel free to mention that in the comment below. Also, please comment below if you have any questions and find this article vague/helpful/excellent!
