Introduction

When working with the Windows Command Prompt (CMD), it's common to use the up arrow key to retrieve previously entered commands. However, this feature also stores a record of all commands entered in the current session, which can be a security concern if you're working on a shared computer or if you've entered sensitive information. In this article, we'll explore whether it's possible to clear the command history in Windows Command Prompt and provide a step-by-step guide on how to do so.

Understanding Command History in CMD

Before we dive into clearing the command history, it's essential to understand how it works. When you enter a command in the Command Prompt, it's stored in a buffer, which is a temporary storage area that holds data for a short period. The buffer is used to allow you to recall previous commands using the up arrow key. However, this buffer is not cleared automatically when you close the Command Prompt or log off from the system.

Is it Possible to Clear Command History in CMD?

Yes, it is possible to clear the command history in Windows Command Prompt. There are a few methods to achieve this, which we'll discuss in the following sections.

Method 1: Using the `doskey /history` Command

One way to clear the command history is to use the doskey /history command. This command will display a list of all commands entered in the current session, and you can then delete the file that stores the command history.

Step 1: Open the Command Prompt as an Administrator

To use the doskey /history command, you need to open the Command Prompt as an administrator. To do this, right-click on the Start button and select "Command Prompt (Admin)" from the context menu.

Step 2: Use the doskey /history Command

Once you've opened the Command Prompt as an administrator, type the following command and press Enter:

doskey /history

This command will display a list of all commands entered in the current session.

Step 3: Delete the Command History File

The command history is stored in a file called cmdhistory.txt in the user's profile directory. To delete this file, you can use the del command followed by the path to the file:

del %USERPROFILE%\cmdhistory.txt

This will delete the command history file, effectively clearing the command history in the current session.

Method 2: Using the `cmd /clear` Command

Another way to clear the command history is to use the cmd /clear command. This command will clear the command buffer, which includes the command history.

Step 1: Open the Command Prompt

Open the Command Prompt as you normally would.

Step 2: Use the cmd /clear Command

Type the following command and press Enter:

cmd /clear

This command will clear the command buffer, including the command history.

Method 3: Using the `net session` Command

If you're using Windows 10 or later, you can use the net session command to clear the command history. This command will display a list of all active network sessions, and you can then delete the command history file.

Step 1: Open the Command Prompt as an Administrator

To use the net session command, you need to open the Command Prompt as an administrator.

Step 2: Use the net session Command

Type the following command and press Enter:

net session

This command will display a list of all active network sessions.

Step 3: Delete the Command History File

The command history is stored in a file called cmdhistory.txt in the user's profile directory. To delete this file, you can use the del command followed by the path to the file:

del %USERPROFILE%\cmdhistory.txt

This will delete the command history file, effectively clearing the command history in the current session.

Conclusion

Clearing the command history in Windows Command Prompt is a straightforward process that can be achieved using one of the methods outlined above. Whether you're working on a shared computer or simply want to ensure your command history is cleared, these methods will help you achieve your goal. Remember to always use caution when working with the Command Prompt, and never enter sensitive information without taking necessary precautions.
