After entering password it exit with error:-

My version of gedit (2.22.3) does create the file if it doesn’t exist. If yours doesn’t, you can create the file first with sudo touch /etc/xinetd.d/tftp.

I recommend using sudoedit /etc/xinetd.d/tftp instead. This uses your favorite editor, taken from the EDITOR environment variable, or a system default if you haven’t expressed your preference. Add export EDITOR=/usr/bin/gedit to your ~/.profile if necessary.

I made a new launcher for my desktop (I installed gnome desktop fallback)
by gnome-desktop-item-edit —create-new ~/Desktop.
then typed in as the run command: gksu nautilus
that runs as root.

navigated to my regular home that logs in show hidden files went inside Templates folder, made new file and newfile.php and newfile.html
I also edited those files and put in my code I usually create with.

then I copied the Templates file and navigated to «root’ home the paste it there (the folder is missing) now when I run nautilus as root I can create my files as well as the untittled with no extention. then edit with gedit using the nautilus I launched as root with my new launcher (gksu nautilus)

gksu hasn’t been updated since 2009 and is not recommended any more. In fact, Ubuntu no longer ships with gksu by default (though it may be installed for many of you, because some apps still depend on it) and it may even be completely removed at some point.

The recommended replacement for gksu is pkexec. Applications like Synaptic, Ubuntu Software Center, Software & Updates and others use it for some time but what if you want to use pkexec with applications like Gedit or Nautilus?

For instance, Nemo comes with a such a file and so do Xfce’s Thunar and Mousepad (Xubuntu 15.04), but Nautilus and Gedit don’t support this by default.

There are two ways you can achieve this though:

sudo apt-get install nautilus-admin

And restart Nautilus:

nautilus -q

B) Install PolicyKit files manually for Nautilus and Gedit

— for Nautilus:

wget https://raw.githubusercontent.com/hotice/webupd8/master/org.gnome.nautilus.policy -O /tmp/org.gnome.nautilus.policy
sudo cp /tmp/org.gnome.nautilus.policy /usr/share/polkit-1/actions/

— for Gedit:

wget https://raw.githubusercontent.com/hotice/webupd8/master/org.gnome.gedit.policy -O /tmp/org.gnome.gedit.policy
sudo cp /tmp/org.gnome.gedit.policy /usr/share/polkit-1/actions/

That’s it! Now give it a try — open a terminal and type:

pkexec gedit
pkexec nautilus

For quick access, you can create launchers for running Nautilus and Gedit as root: simply use «pkexec nautilus» or «pkexec gedit» as the command.

What is root folder in Linux?

How do I run a file as root?

You need to do two things; both from a Terminal prompt:

  1. Change to the directory where you have the . run file stored.
  2. Type: chmod 755 filename. run.
  3. Type: sudo ./filename. run.


Once sudoedit is set up appropriately, you can do

SUDO_EDITOR="/opt/sublime_text/sublime_text -w" sudoedit yourfile

sudoedit will check that you’re allowed to do this, make a copy of the file that you can edit without changing ownership manually, start your editor, and then, when the editor exits, copy the file back if it has been changed.

I’d suggest a function rather than an alias:

function susubl {
    export SUDO_EDITOR="/opt/sublime_text/sublime_text -w"
    sudoedit "$@"

although as Jeff Schaller pointed out, you can use env to put this in an alias and avoid changing your shell’s environment:

alias susubl='env SUDO_EDITOR="/opt/sublime_text/sublime_text -w" sudoedit'

Take note that you don’t need to use the $SUDO_EDITOR environment variable if $VISUAL or $EDITOR are already good enough.

The -w option ensures that the Sublime Text invocation waits until the files are closed before returning and letting sudoedit copy the files back.

Desktop environments (GNOME)

gedit admin:///etc/shells

This will prompt for the appropriate authentication using PolKit, and then open the file for editing if the authentication was successful.
