I have a similar question.
I was told never, ever, N E V E R to edit the file. Only use visudo like this:
My question is - why? I mean, If I can edit all other files normally, and change anything, and if it's true that in Linux everything is a file, then why can't I just edit sudoers file like any other.
Maybe there are other similar files,I'm not sure.
Sorry for jumping in, it was just on my mind at the moment and I felt like I could ask here.
