Running sudoedit command on the other hand will create a temporary file in /tmp and edit that as a normal user. The solution to this situation is to use the sudoedit command. This isn't a problem on maintainer packaged software, but still makes me (and several others) uneasy. ![]() Your editor has access to everything now.

The normal convention is to use Ctrl + s key combination to save your work, but in Nano, the keyboard shortcut is Ctrl + o. Here is a graphical demonstration where I edit the previously opened 'demo-file.txt' file in nano.Īs you can see, this is quite effortless and easy to use! Save and close files To cut a line, press the Ctrl + k key combination, and to paste, press the Ctrl + u key combination. Text can be selected using the normal click-and-drag mouse operation.
