The choice of editor depends on the env variable EDITOR.
Set the env variable to say vi, export EDITOR=vi

Actually, in Debian and Ubuntu the editor is set by the alternatives
system. "visudo" will use the alternative set for "editor". You can change
it using the command

sudo update-alternatives --config editor

The EDITOR and VISUAL environment variables are not set by default. You can
confirm this by typing

echo $EDITOR
echo $VISUAL

Having said that, it certainly will also work to do,for example

export EDITOR=vi ; visudo

( or indeed export VISUAL=vi )

By default, if you type "editor" you will get whatever is set by the
alternatives system - normally nano, unless for example you have installed
"mc", in which case you get "mcedit" unless you change it with
update-alternatives. All this depends on the priority set - see

sudo update-alternatives -display editor

Or use update-alternatives.

I never found the password. But after loading the live CD I went to
System -> Admin -> Users and Groups and you should see your messed up
user and root. Select each to fix them and on the root make sure you
give it YOUR password. Then you will know.

I just set env variable to say joe, with export EDITOR=joe. I need to
test it :-)

Can I put out a plea for plain text submissions to this and other groups
please? The above is what I see at this end. Not exactly a model of
lucidity.

I quite agree on all counts... but I'm interested to find out what actually
happens at your end. On your mail I see

User-Agent: KMail/1.9.6 (enterprise 0.20070907.709405)

Does kmail not segregate text/html from text/plain ?

Here on Sylpheed, I see the "Binish A.R" post as two parts, one text/html
and one text/plain... actually both are readable, but I would have thought
that it was possible to tell Kmail to read text/plain by default?

Or is this some kind of magic of which I'm unaware? <grin>

> <dons flame-proof suit>

Not really required in this case ;p Could be handy though - where did you
get yours? Is it GPL ?

Well, Kmail shows the HTML garbage as it is because there is no plain text
part for the main message in the original mail. So if Kmail would show
the plain text part, it would be only the mailing list signature. If
there are both HTML and plain text for the main message, it displays the
plain text version of the main message. Anyway, that is a question of
preference settings. Kmail can be set to prefer the HTML display, but
fortunately that isn't mandatory.

Does Sylpheed show the HTML part as is or does it show it without the
code? And if it is without the code, is it like plain text or with the
markup?

The root account is enabled, but it isn't
given a password, so you can't access it directly.* What you have to do
is to sudo passwd root and enter a password.* Since you've zapped your
sudoers file, you probably can't do that.* Personally, I much prefer to
do a su and know I'm a superuser than to depend on sudo for
everything.* But that's my preference; evidently most Ubuntu users have
a different preference.



cheers,

Or just do

sudo -i

Yes he can. If you boot in "recovery" mode you get a root prompt... see my
other post.

Either way is fine, except that if you give yourself a root password, the
trick above won't give you a root prompt by default, so you'd better make
sure you remember your root password
