Open Files & Folders with Administrative Root Privileges in Nautilus, Ubuntu’s File Manager

The Nautilus extension nautilus-gksu is an invaluable enhancement forUbuntu‘s default file manager. Once installed, it allows you to open files and folders as root or superuser simply by right-clicking and choosing “Open as administrator” from the context-menu.

This is great if you’re in a system folder and decide to edit a config file. Simply double-clicking would bring up the text file in your text editor, but you wouldn’t be able to save any changes. Rather than type the command to let you achieve this in a terminal, you can just right-click it and open it as the administrator.

Similarly, if you are working in a protected folder and need to edit files, move ordelete any of the contents, and even copy things into it, open the whole folder with this option, enter your password, and away you go. You will notice anyNautilus windows that appear will not be themed like the rest of your system, as those instances of Nautilus are in fact being controlled by root (if you ever logged in as root, which is never really advised these days, you’d see it has a basic theme and no desktop effects).

This option for folders is really handy, as there are times when even a novice user can benefit from having full access to a system folder. For example, if you’ve downloaded splash themes for GRUB bootloader and the Usplash/XSplash/Plymouth screen that comes after it, it is certainly much quicker and easier to open the appropriate system folder in this manner, then drag-and-drop new themes/splashes in, rather than have to type commands in the terminal to do so for each file.

To install this extension, enter the following into a terminal:

sudo apt-get install nautilus-gksu

Open a Terminal on the Folder in Ubuntu

What does “Open a Terminal on the Folder in Ubuntu” mean?

When you see instructions telling you to open a terminal window in a specified folder, it means that in order for whatever commands you’re entering to work, theterminal (the interface for entering commands) needs to be looking in the right place (it looks to the desktop by default).

Previously, your only option would have been to open a terminal (Ctrl+Alt+T, or start typing “terminal” into Unity’s Dash menu, or open Applications > Accessories > Terminal if using Gnome “Classic”), then use the change directory command (cd) to make it point to the folder you need to work with.

eg: cd /home/yourusername/Pictures

In Ubuntu, your default file manager, Nautilus, gives you the option of opening a terminal in the folder you’re looking at, saving you manually opening a terminal and changing directory. So using the example of your Pictures folder, you would have that open in front of you, then right-click an empty area and choose Open in Terminal from the menu. Then enter your commands and you’re in business!

If you find for some reason that you don’t have the Nautilus plugin that gives you the context menu option, simply open Synaptic or Ubuntu Software Centreand search for and install the following package, and all will be fine:

nautilus-open-terminal

If you want to be even quicker, paste the following into a terminal:

sudo apt-get install nautilus-open-terminal

You’ll need to totally restart Nautilus, which you can do with either killall nautilus or nautilus -q in the terminal, or via Alt+F2.

Additional Notes:

In case you’re wondering how to customise your terminal with colours and different characters for the prompt, check out this guide!
