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.

Ok, I managed it by myself after a bit of tinkering. This is the bash script:
Obviously change the path the .wav audio file to suit yours (I downloaded mine from the internet). Then, save the file (in my case, I named it battery.sh), make the script file executable (
chmod +x battery.sh
via the terminal, or via the file manager).Then add it to the Startup Applications settings panel on your distro (usually gnome and cinnamon have one). The alarm will sound if the battery reaches below 21%.
Worth running shell scripts though https://www.shellcheck.net/ (has a cli as well). Finds lots of common issues that can blow up scripts when input is not what you expect. With links to why they make the suggestions they do.
That's a neat tool!
It works fine, so I'm ok.
The problem with bash scripts is they tend to explode in unexpected ways when thing don't go as intended. This could be one of the command you run returning some expected or not output which might work now but might not in the future. Best to program bash defensively.
Since you say
fyi, the sys BAT paths are also different per laptop. Just in case it doesn't work for somebody else or for you on a different laptop.
