Is there a way to add "Run as Sudo" to context menu like with Windows?

Do not do this. "Run as Administrator" is a Windows answer to a Windows problem. The only time you should regularly need root privileges is installing software and editing system wide configuration files.

Your polkit will always prompt you for a password. No need to complicate it. If it doesn't, then it doesn't need to be ran as root

I don't know why everyone is getting self-righteous about this. I've used Linux since the mid-90s, and occasionally I find it easier to just run a GUI file manager as root to do some filter and deletions of things in caches and such that need root permission. Hell, I want to edit the files in /etc/wireguard for my tunnels; should I only do this at a sudo prompt in the terminal when I'm perfectly capable of pulling it up in Kate and copypasting stuff in?

Get off your high horses, there's plenty of valid use cases if you're using your head.

AFAIK the newer Ubuntu gksu equivalent is pkexec, if that helps.

You could copy all system .desktop files to your home dir and automatically edit them with a script that adds an action to run them with pkexec or sudo as root. However, most GUI apps should never be run as root, because they can break the system. For example, they may create hidden thumbnail files owned by root and break thumbnails in all apps not running as root that way

I do not really see hostility or taking down. More of a difference of opinion or experience.

Also, this is not a private email thread. It is a public forum. Whatever advice you get risks becoming guidance for the community. I think it is perfectly reasonable, even responsible, for people to respond with their thoughts on security.

You can ignore the advice not to implement this capability on your personal machine. That is your call. However, this should not become standard practice by Linux users.

Thank you for answering at some point in the thread the use cases that drove your question. I was very curious.

When I have needed “Run as Administrator” in Windows, it has typically been to run the command line. The reason Windows needs this is because it has lacked “sudo”. The next release of Windows is adding it as a feature ( going the other way ).

I have used Linux for decades as well and really not needed this. Partially this is because tools that require root access are typically configured to ask for it already.

Your “need to delete a file” use case made sense to me but I do not run into it. Perhaps my file systems are mounted differently. Perhaps I am not manipulating files of other users ( sounds right ). Or maybe I am more likely to be at the command line. Your “edit files as root” use cases leads me to believe I use the command line more as that is certainly something I would be doing from the terminal. I have to edit files as root everyday but it is always from the terminal. I am not encountering files that I cannot edit in my file manager though as I would have navigated to those files in the terminal to begin with. Clicking around in a file manager to get to system files is not even something that would have occurred to me. If I am using the file manager, it is to manage my own files ( mostly media and documents ).

No judgement. Do things how you want. I was just curious what you were using this for. When I use Windows, I use “Run as Administrator” all the time. In Linux, I did not even notice it was missing. Going back to Windows makes me miss “sudo” in the terminal though. I am not the only one obviously as they are now adding it to Windows too.

What's the use case? What are you running into that you want to launch as sudo through the gui that isn't pulling up the dialogue automatically?

A few folks have argued this is unnecessary, but I'm curious about your perspective on why and when you think it would be useful

Sudo is "su do", i.e. "run as root", so it's funny to hear run as sudo because it means "run as run as root", like "chai tea" or "ATM machine".

To your question the answer is "why?". You shouldn't need that, that's one of the hardest things to get rid of, the "Windows mentality", it's like when people ask how to install a .tar.gz they downloaded from the internet, the answer is most likely "you don't need that".

This leads to an XY problem, where you're asking how to solve problem Y but that is caused by you assuming you need to do X, when in fact you don't. The main clue is that people keep asking you why do you want to do this. So, what exactly is the problem you're trying to solve? Why do you think you need this?

You don't need to run any GUI programs as root.

There is a lot of advice in this thread warning you about doing this. Please heed it. Instead, read more about how permissions and file ownership works.

Don't know about gnomes default file manager, but dolphin has this ability. You'll have to install the addons and enable it in the context menu however.

To repeat others opinion though, I haven't actually needed this feature outside of very specific situations (that I create myself). Linux operates a bit different and shouldn't need this for anything outside of some poorly made, or potentially malicious apps and scripts. I agree though it's still nice to have the option

Thunar has 'custom actions'. Add one using pkexec %f. Other FM have similiar functionality.

It depends on the file browser you are using.

That's not a good idea as root isn't the same as an Administer account. Also, you might want to consider why you are running programs as root. You may have a chicken and the egg problem.

Maybe step back and give us some more context.

YOU CAN'T DO THAT

This is very easy in KDE but Desktop entries work the same on all Desktops.

See this post where I mentioned how to do this with running Konsole with root.

In general, use polkit instead of sudo, every desktop has a GUI dialog that pops up.

pkexec APPNAME

And add this as a desktop action, following the guide.

[Desktop Entry]
Type=Application
Exec=konsole
Icon=utilities-terminal
Categories=System;TerminalEmulator;
Actions=root
Name=Konsole
GenericName=Terminal
Comment="$GenericName"

[Desktop Action root]
Name=root
Icon=folder-root-symbolic
Exec=pkexec konsole

In the specific case of Konsole you could use a profile instead.

Be aware that nearly no program should be ran as root. Also not Konsole. The program is ran as the user, and can enter a root shell, but never run random apps as root. Not even many terminal apps are made to be ran as root, for example use sudoedit instead of sudo nano for editing files.

To view and change system files in KDE, type admin:/ into the location bar.

Running apps as root doesnt work with Wayland, and for a good reason.

For context, I answered this after your edit. First, I don't know how to add another context menu on a file manager, but I imagine if there is a way to do that, there is a command to be run when doing it. Hence, what I will answer is only the command.

For editing a file, you absolutely don't need to open the editor as root. You can however, make a temporary copy of a file that your own user has access to, edit those temporary files, and when you are done editing it just replace the old file. This is what sudoedit FILE does.

Secondly, for manipulating a file, I agree with the other commenter that it still is a bad practice to run the file manager as root. Instead, try to add a context menu for taking ownership of a file/folder recursively. chown does exactly that. Of course chown won't save you if that file is a network mount with some form of other access control.

Third and last, yes I agree that if a user wanted to nuke their installation it is their right to do so. However, do remember that this is also a forum and that we always remind each other the best practice since maybe another user will stumble upon this and think "oh, this is how it is in Linux". We do not have the equivalent of "Run as Administrator" here in linux as that would mess up a lot of assumptions for other programs and easily make the system unstable or outright unusable.

something like this? creating custom context menu options

https://www.howtogeek.com/116807/how-to-easily-add-custom-right-click-options-to-ubuntus-file-manager/

I'm assuming you're using the nautilus file manager. I found this post in adding right click actions to nautilus: https://askubuntu.com/questions/210192/how-can-you-add-an-item-to-the-right-click-menu-in-nautilus-without-nautilus-ac#672553 You could make a bash script like shown in the post and use polkit to open the password prompt and run a command as root.

Emacs can let you edit root files using TRAMP

There's also YaST , but that's an OpenSUSE thing.

I think you can run like this:

$ pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY <yourapp>

For example, if I wanna open kgx (a.k.a. Gnome Console), I would run:

pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY kgx

I see no "hostility" and "talking down" here. You shouldn't be running GUI programs with sudo, and the fact that you've been using Linux for X amount of years doesn't change that.
