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)
Currently, the only way I was able to achieve this was to use rmate.
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.
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
Press F1 and run Search for the Remote: Start Server
command.
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
Don't know if this is the best approach but it worked for me. Note that this should only be used on files that only root has access to in the first place. I think saved files will be owned by root. Use this to quickly change some settings but not to write code that can done by regular user.
sudo apt install ssh
Edit or add PermitRootLogin yes
inside /etc/ssh/sshd_config
sudo service ssh stop
sudo service ssh start
Ctrl + Shift + P
-> Remote SSH: Add new ssh host
-> root@127.0.0.1
accept all fingerprints and stuff and you're in as root. You should be able to do anything now.
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.
input this in powershell and press 'Enter'
ubuntu config --default-user root
then you will login wsl with root user and you can do anything now
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
