Running and Managing Environment Variables in CMD

Understanding and managing environment variables in CMD is crucial for any Windows user or developer who needs to set up a custom environment for their applications or scripts. This guide will walk you through the steps to view, set, and modify environment variables using CMD.

Viewing Current Environment Variables

If you want to see the current environment variables set in your system, you can use the set command in CMD. However, by default, CMD will display all the environment variables in a single line, which can be difficult to read. To make it easier, you can use the set command followed by more:

Open CMD. Enter the following command and press Enter: set more

This will display the environment variables one at a time, making it easier to read and manage.

Modifying Environment Variables

Once you have identified the environment variable you want to modify, you can use the set command to change its value. Here’s how:

Open CMD. Enter the set command followed by the environment variable you want to modify, followed by the new value. For example: set pathC: ewpathaddedtopath

Opening the Windows Environment Variables Dialog

If you prefer to open the Windows Environment Variables dialog directly from a launcher application such as SlickRun, you can do so by using a single command. Here’s how:

Open SlickRun (or your preferred launcher). Enter the following command: cmd /c cplEditEnvironmentVariables

This command will open the System Properties window, where you can easily edit the environment variables through the Environment Variables... button.

Conclusion

Managing environment variables in CMD can be a powerful tool for customizing your Windows environment. Whether you need to quickly view, set, or modify environment variables, CMD provides a straightforward way to do so. Understanding and utilizing these commands can save you time and make your development and administrative tasks much smoother.
