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.

The arch wiki has a udev rule that can automatically do something if the battery crosses a certain threshold: https://wiki.archlinux.org/title/Laptop#Hibernate_on_low_battery_level
No polling which is great. I always try to do stuff on an event driven basis where possible for efficiency reasons. Gotta test this out though, since your battery might not send events for every percent change.
