 ```bash
-(my_env) $ conda deactivate

 A workspace is suitable to store the compressed Conda environment archive on Hawk. Proceed to the next step if you have already configured your workspace. Use the following command to create a workspace on the high-performance filesystem, which will expire in 10 days. For more information, such as how to enable reminder emails, refer to the [workspace mechanism](https://kb.hlrs.de/platforms/index.php/Workspace_mechanism) guide.
