I now know that I should never try to edit the
etc/sudoers file with a regular text editor. However, minutes before I learned this, I saved a new user name in the file with Sublime Text. Now when I run
sudo cat sudoers for example, I get the following error:
>>> /etc/sudoers: syntax error near line 1 <<< sudo: parse error in /etc/sudoers near line 1 sudo: no valid sudoers sources found, quitting
How can I get out of this quandary?
