VSCode in WSL: how to sudo a root file so I can edit it

Question

WSL v.1 -- VSCode v1.40.1 (using 'Remote - WSL' extension 40.3)

How to open a root-owned file for edit using sudo and VSCode? (without running as root)

If I open a root file without sudo, I can't edit it (expected): $ code /etc/profile.d/custom-profile.sh $

But, if I try to sudo code the file, I get:

$ sudo code /etc/profile.d/custom-profile.sh
[sudo] password for xxxx:
sudo: code: command not found

Binarify's answer below shows that I can switch the default user to root, but I definitely don't want to be running as root, so I'm still looking for another solution.

Answer 1

You can own the file you want to edit, then give it back the ownership afterwards

sudo chown myuser /path/to/file
code /path/to/file
sudo chown root /path/to/file

Answer 2

I got the same error , i was not able to save any file in vscode after editing and it was resolved by the following command :

sudo chown -R <user-name> <directory-name>

It worked for me , Hope it works for you too. Thank you

Answer 3

Set environment variable:

export VISUAL="code -nw"

Then you can edit any file like this:

sudo -e file

It will automatically make a copy of file, and, when you close the editor, copy it back.

Answer 4

Currently, the only way I was able to achieve this was to use rmate.

1. Install rmate on your WSL VM

sudo wget -O /usr/bin/rmate https://raw.githubusercontent.com/aurora/rmate/master/rmate
sudo chmod a+x /usr/bin/rmate

I'm using a Debian Buster WSL here, however you can replace /usr/bin with an appropriate folder in your $PATH depending on your OS or your preference.

2. Install the Remote VS Code plugin

make sure the Extension is enabled on WSL: after adding the plugin.

Here is how I configured the remote VS Code plugin

File -> Preferences -> Settings

3. Start the VSCode rmate server

Press F1 and run Search for the Remote: Start Server command.

4. Edit your privileged files

Start your WSL instance and open a terminal. If you've done everything correctly you should be able to now edit your files with sudo priveledges in your editor, even if you are not the root user.

sudo rmate /etc/profile.d/custom-profile.sh
