How to save a file?

jpostma · 11-28-2007, 12:20 PM

I want to change the contents of a config file with a text editor. When I want to save the file I am getting an error that I do not have permissions.

The only way I'm thinking of is with 'sudo vi <filename>' but I prefer to edit a file with a text editor.

vi is a text editor

You should be able to launch your favourite text editor in much the same way as you launch vi:

Code:

sudo <your_text_editor> <file_name>

So with kedit, that might be:

Code:

sudo kedit <file_name>

This is not very user friendly. I want to select a file with Nautilus and click on the right mouse and open the file with a text editor.

In that case, I don't know. Sorry

I'm sure it's possible though. Have a look through your KDE/gnome menu and see if you can launch nautilus as a superuser.

I think he means he wants to use a GUI text editor as root. But, root doesn't normally have GUI ability in the users environment.

Here's how to let root have GUI:

From the command line, as user:
xhost + localhost

Then su to root, and start the app from the command line:
kedit

When kedit opens, from the kedit menu, File - Open
and find the file to open.

Thank you for the information. I have created a new menu item with the command 'gksudo nautilus'. Nautilus will now be opened with the root user.

If I'm not totally mistaken, that's something you really should _not_ do, ever (for security reasons).

gksudo is the graphical sudo app, and the way to go when needing superuser rights without accessing commandline - so adding a new Nautilus entry is the right thing to do. The other way is, like mentioned,
