From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This is my second "I feel like a complete idiot" question of the week, so thank you for your patience.

How does one find an app-id, e.g., for setting up window rules in my window manager (River)? For example, if I'm using Nautilus as a file manager and I wanted to have the Nautilus Previewer window float by defining a River WM rule, I can do every bit of that trivially, other than identifying the app-id. (In this case, I believe it's org.gnome.NautilusPreviewer, but I'm looking for a general case.) Please note this question is about Wayland and not X.

I dropped into GNOME and viewed active windows with Looking Glass (lg), but that seems like a silly workflow just to ID a window.

I dropped into GNOME

And I dropped into a Qtile X11 session and used xprop! I'm not sure if river provides a native way to do that.
