How to launch application as root from Unity Launcher?

Question

Mainly I am looking for a way to pin an application to the Unity launch bar, and run it as root.

Currently, even if I start the application with sudo, and pin it after it starts, it will start as current user next time.

Sad, but there is no context menu option "run as ...".

Update: I switched to gnome3 and now I'm happy, I'm missing only the search.

Answer 1

If you want the app to always run as root

1. Pin the application to the launcher as normal.

2. Locate the applications .desktop file which will be in either:

   • /usr/share/applications/APPNAME.desktop
   • ~/.local/share/applications/APPNAME.desktop
   • or somewhere else, use locate .desktop|grep APPAME

3. Open with gedit:

   gksudo gedit /usr/share/applications/APPNAME.desktop
   

4. Then change the line

   Exec=APP_COMMAND
   

   to

   Exec=gksudo -k -u root APP_COMMAND
   

5. Save

This command will also keep your environment which is very usefull if you need to connect to others servers and use your private key.

To add a quicklist option to 'Run as root'

Follow steps 1, 2 and 3 above

If the launcher currently doesn't have any other quicklist options, just append this to the end of the document

X-Ayatana-Desktop-Shortcuts=Runroot

[Runroot Shortcut Group]
Name=Run as root
Exec=gksudo -k -u root APP_COMMAND
TargetEnvironment=Unity

Answer 2

In the Main Menu under System, Preferences, type gksudo in the Command field of Launcher Properties, e.g.:

/usr/bin/gksudo /usr/bin/yourapplication

Your Name field might say:

sudo yourapplication

So users know they may see a password popup and why...

I am not sure about Unity Launcher vs Main Menu. Maybe this helps?

Good luck

The following seems to do the same thing, without needing private attributes:

Actions=Runroot;Another

[Desktop Action Runroot]
Name=Run as root
Exec=gksudo -k -u root APP_COMMAND

[Desktop Action Another]
Name=Another action
Exec=whatever

Answer 4

As a quick and simple alternative to the cumbersome demands described in the answers here, I've gotten in the habit of doing the following...

1. Launch a new terminal.

2. Enter gksu nautilus

   (sudo -i nautilus works, too.)

The resulting window falls under the sudo umbrella, so you can use it to access and launch files with sudo-root privileges to your heart's content until it closes. This comes in handy for transitory situations where you don't need a more permanent solution. I use it routinely to extract compressed files into protected system folders, for instance.

Answer 5

This should perhaps be a comment on Daniel's solution. It works for me, even in Ubuntu 15.04. I had to put the command between quotes Exec=gksu "nautilus --new-window" because of the extra argument. Also, somehow, I don't know why, I had to edit the launcher directly in order to keep the original menu (together with the new option). If you drag your own launcher, it will get registered, but you will not have the same menu.

In Ubuntu 15.04, the launcher for nautilus is usr/share/applications/org.gnome.Nautilus.desktop. You have to use the command line to see the real file name.

Further research lead me to what I believe is a better option : http://ubuntuhandbook.org/index.php/2014/04/ubuntu-14-04-add-open-as-rootadministrator-to-context-menu/ . Instead of opening Nautilus entirely as Root, this allows you to open selected directories as Root within Nautilus. Anyway, I checked, and these two options are compatible. If you open Nautilus as Root and then use the second option to open a directory as Root, it simply opens it without asking the password.

Answer 6

Im posting this in-respone to the question @Chris asked in comments :

Suppose you want to create a launcher which will open "file manager(nautilus)" as root. Then you can do this:

Open terminal. Type:

sudo -H gedit /usr/share/applications/nautilus_root.desktop

Hit enter. When asked, enter your login password and hit enter. This will open gedit (text editor). Now, paste the following there:

[DesktopEntry]
Encoding=UTF-8
Name=Nautilus(Root)
Comment=FileManager
Exec=gksu nautilus
Icon=file-manager
Categories=System;
Type=Application
Terminal=0

Now, just save it and exit. You are done. Now if you search on dash then you will find a new launcher "Nautilus (Root)". Clicking this will ask you password, and upon authentication nautilus will be opened as root.

Note: Be careful when you are running "Nautilus (Root)". In this mode you can delete almost anything from / and break the system.
