You are comfortable editing a text file? Because that's all it is
about.

Visudo is just a wrapper around an editor (I guess it expects
a console based one, but whether it's vim or nano or joe or
whatnot, it's settable via the EDITOR environment variable).

It hasn't to be vi or vim (if that is what scares you).

Thing is, you /can/ just edit /etc/sudoers by hand, but if you
make a mistake, your box may end in a state in which you can't
login anymore (or you can't invoke sudo, thus hindering your
attempts at fixing the situation). Nothing unsurmountable, but
definitely annoying. The visudo wrapper tries to catch some
mistakes before they lead into harm.

Or is it the prospect of editing a text file which puts you
back? (I don't believe so, I "see" you doing that all the
time :-)

Do you have any favorite (console based) editor?

Although it seems visudo can cope with a graphical editor [1],
I've never tried that. Perhaps someone around here has.

Cheers
