Hi @Sharma_Shruti
Are you configuring the wsk cli or the aio cli?
The .env file only applies if you are configuring the Adobe I/O CLI. After you create the `.env` file within the current working directory, update it with your Runtime credential and save the file. When you are in this directory, and type in `aio runtime property get`, all the values should be automatically picked up and shown here. You can proceed to execute any `aio runtime` commands, including deployment commands.
Alternatively, if you already have a `.wskprops` file in your root directory, the Adobe I/O CLI picks that up automatically as well.
Hope this helps.
