Earlier today I got a cold sweat moment after I accidentally ran a
sudo rm /etc/group.
I just wanted to edit a line, not to delete an entire file!
Good thing is that system occasionally backs up files in
/etc folder. If there’s
group there’s also an older
Unfortunate that I could no longer sudo from the current user, since
group file no longer existed.
If you run into this kind of issue:
Reboot your computer
Choose Advanced options for Ubuntu
Select drop to root shell prompt
When a root terminal opens, you know what to do.
Besides not doing
sudo rm -rf ... , which can happen again btw, it’s a good idea to add
etc folder to versioning.
