How To Remove the “y/N” Prompt When Typing “code .” in WSL Ubuntu Distro?

Ubuntu 18

In this article, we will discuss how to remove the “y/N” prompt that appears when typing the code . command in the Windows Subsystem for Linux (WSL) Ubuntu Distro. This prompt can be a bit annoying, especially if you frequently use Visual Studio Code in WSL.

Quick Answer

To remove the "y/N" prompt when typing "code ." in WSL Ubuntu Distro, you can either set the environment variable "DONT_PROMPT_WSL_INSTALL=1" for the current session or in the .bashrc file, or create an alias in the .bashrc file. These methods will disable the prompt and allow you to use the "code ." command without confirmation.

Understanding the “y/N” Prompt

When you type code . in your WSL terminal, you might see a prompt that asks you to confirm with “y/N”. This prompt is asking for your permission to install the Visual Studio Code Server on your WSL distro. Once you give your consent, it will not ask again. However, if you want to avoid this prompt entirely, there are a few methods you can use.

Method 1: Setting the Environment Variable for the Current Session

The first method involves setting an environment variable for the current session. Here’s how you can do it:

  1. Open a terminal in WSL.
  2. Run the following command:
DONT_PROMPT_WSL_INSTALL=1 code .

In this command, DONT_PROMPT_WSL_INSTALL is an environment variable that Visual Studio Code checks before prompting to install the VS Code Server. Setting it to 1 disables the prompt.

Method 2: Setting the Environment Variable in the .bashrc File

You can also set the environment variable in the .bashrc file so that it applies to all terminal sessions. Here’s how:

  1. Open a terminal in WSL.
  2. Open the .bashrc file in a text editor with the command:
nano ~/.bashrc
  1. Add the following line at the end of the file:
export DONT_PROMPT_WSL_INSTALL=1

In this line, export is a command that makes the variable available to child processes of the current shell.

  1. Save the file and exit the text editor.
  2. Apply the changes with the command:
source ~/.bashrc

The source command reads and executes commands from the file specified as its argument, in the current shell environment.

Method 3: Creating an Alias in the .bashrc File

Another method is to create an alias in the .bashrc file. This method is useful if you don’t want to set the environment variable globally. Here’s how:

  1. Open a terminal in WSL.
  2. Open the .bashrc file in a text editor with the command:
nano ~/.bashrc
  1. Add the following line at the end of the file:
alias code='DONT_PROMPT_WSL_INSTALL=1 code'

In this line, alias is a command that enables you to replace a word with a string.

  1. Save the file and exit the text editor.
  2. Apply the changes with the command:
source ~/.bashrc

Conclusion

In this article, we discussed three methods to remove the “y/N” prompt when typing code . in WSL Ubuntu Distro. These methods involve setting an environment variable or creating an alias in the .bashrc file. Remember to apply the changes by sourcing the .bashrc file. If you still encounter issues, ensure that you have followed the instructions correctly and check for any syntax errors in your .bashrc file. Happy coding!
