[SOLVED] Why some programs are able to edit /etc/hosts while others are not?

Issue

I tried to edit my /etc/hosts file using Emacs, VSCode, etc. (with sudo, of course) and it kept saying that I did not have the permissions to edit the file.

Then I tried with Vim, Nano and Atom... and those were able to edit and save the file.

(Running echo 'some host' | sudo tee -a /etc/hosts has also worked just fine).

So why is that? Why some editors can edit the file without any problem while others don't?

Solution

Try to open C-x C-f /sudo::/etc/hosts with your local emacs.
