xdg-open

balanga · 2026-03-31T07:06:09+0100

I have only just become aware that I have a /usr/bin/xdg-open.

I don't where it came from but I've just found that if I'm using dired in doom emacs and press '!' I get a prompt for which command I want to run on the current file.

I must have set something up a while ago but don't remember. Is there some sort of config file? I can't find one.

I think,
~/.config/mimeapps.list

Read xdg-settings()

This file has some reference to emacs being the default program for text files.

/root/.config/lxsession-default-apps/settings.conf

But ONLY , when you log in as root , and then only when you use lxde/lxqt as desktop manager. Otherwise config is not known.

I'm always root, I don't have any users.

lxde is my Window Manager.

How do the values get set? Is there a configuration editor?

It's been a while since I've used lxde but there should be a configuration settings somewhere in the menu structure.

Is this the answer

Code:

Using the GUI 
[*]Open PCManFM and navigate to any file with the extension you want to change.
[*]Right-click the file and select Properties.
[*]Go to the Open With tab.
[*]Select your preferred application from the list.
[*]Note: If your app isn't listed, click the "Add" button to find it in the applications menu.
[*]Click the "Set as default" button (or "Make default").

xdg-mime(1)
The package is xdg-utils.

You obviously have poor OPSEC. Even after being electronically scammed out of money you still flout the norms. Why?

Running a Web Browser as root user is probably the greatest inflection point. Do you realize what a web browser can do? Now give it unlimited root access to your system...

Please enlighten me.

I cannot believe that I have to convince you to act like a normal person. This is not something obscure.

Running a web browser as root is generally a bad idea. Doing so opens your computing environment up to possible attack from outside sources. In this article we'll discuss the vulnerabilities and attack surface when running a web browser as root.

Any JavaScript run as ROOT is a horrible idea. Browsers interpret JS. Ponder that.
