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.

How to display a symbol similar to the undervoltage symbol on raspberry pi (self.linux)

I want to display a symbol at the top right of one or both of my screens, similar to the lightning bolt symbol raspberry pi OS uses to indicate lack of power, when certain conditions are met.

I'm pretty sure i could cobble a bash script together to decide when to do it, but it's the actual displaying of the symbol i'm not sure where to start on. It would need to appear on top of anything else that may be on the screen at the time

Everything i have tried googling returns irrelevant results

Why not just look at the lightning bolt code and use that?
