I'm using Ubuntu 18.04.

I renamed the /etc folder to apache2. That was my greatest mistake

Now I can't rename it back because I need to use sudo, but when I try I get the error

sudo: unknown uid 1000

How can I fix this problem? I don't have a live system to boot from, and in recovery mode the root terminal opens but then closes saying cannot open password database.

sudo etc

I'm working on a bash script that appends to /etc/profile but instead of appending, I accidentally wrote over it, losing all of its content. How can I restore the file? I did search here but being new to Ubuntu, I don't know if the posted /etc/profile content I see in other questions is the default content.

.profile etc

What does /etc/alternatives stand for? How and why is it used?

I found gnome-tex-editor in /usr/bin which is linked as follows:

/usr/bin/gnome-text-editor -> /etc/alternatives/gnome-text-editor
/etc/alternatives/gnome-text-editor -> /usr/bin/gedit

So gedit and gnome-text-editor seem to be the same thing.

So why are some commands (e.g.: gedit and gnome-text-editor) provided twice?

And what is the use of /etc/alternatives/ - how does it work?

I've assumed /etc/default was a handy place to save the post-install/default state of configuration files so that when some poor sysadmin arrives at a new system she can quickly determine what has been customised on that instance.

But having just had a look around in there it seems I am mistaken? So apologies if this is a dumb question...

  1. What's supposed to be in the /etc/default directory?
  2. Where would it be appropriate, or is there a convention, for saving the default state of config files?
