How to use visudo

If you don’t know what it is, you probably shouldn’t be using it. That said, to edit your /etc/sudoers file you need to use

sudo visudo

You have two “modes”
• Command mode – Press ‘ESC’ to access.
• Insert mode – Press ‘I’ to access.
You’re always in one or the other.

• To move the insertion point around, press ‘ESC’ and use the arrow keys.
• Once you’re where you want to be, press ‘I’ and start entering text.
• To delete a character, you need to be in command mode, select the character and press the delete key. (Note: not the Backspace key) You can do this in insert mode, but it does some funky things with the text.
• To save your changes, in command mode, type :w and press enter.
• To quit, in command mode, type :q and press enter.
• To quit without saving any changes, in command mode, type :q! and press enter.

Be careful, if you mess it up, you will no longer be able to sudo. Then you need to sudo to fix it. Bit of a problem there. To fix it, you need to login as root, run visudo, and fix the file.

    This was helpful. Thanks for posting it. For some reason I couldn’t delete text correctly until I realized I had to type ‘d’ and then press the right arrow. Pressing ‘d’ then down would delete a whole line! ‘Vi’va la Emacs!

    The most suitable time might well be established through the help of
    a high quality marketing professional. It is the newest way to interact with with customers or visitors and the best aspect is, you have complete approval of your focus on if you are using
    a Facebook or myspace application. I have friends who began with a personal profile for a business.

    The good news is that the same can be purchased
    almost from all locations as long as one has access to the internet.
    Within the game, the player should not only collect
    Pokemon, but must also collect badges by earning them.
    Once released, it not only enables you to watch the episode at any time you wish to,
    you can also go on and enjoy it over and over again.
