I don't think it's that simple. The challenge is that you need to still behave as if it's invoked as the user so that the editor uses their configurations instead of simply
exec
ing it asroot
.I could be wrong though
¯\_(ツ)_/¯
Sudo uses the setuid bit or whatever, so it still has access to the user's environment variables and whatnot. So figuring out which editor to run shouldn't be an issue.
That's not what I mean. Yeah, getting the environment variables are simple enough, but if you simply
exec
something as theroot
user, whatever youexec
will naturally be looking for configs in/root/.config
and not your~/.config
dir, so any configurations to things like your text editor won't be read.Ah, makes sense. It's easy enough to duplicate the outer ENV for the sub-process, but I don't know what that means for security and whatnot.
