I want to run print out my laptop's battery percentage whenever it changes.
I tried running echo "/sys/class/power_supply/BAT0/capacity" | entr cat /_" but it only
executes once.
Why is that?
Thanks!

Unfortunately inotify(7) only supports "regular" files not devices and files used as an API. It's a limitation in the kernel.

You're not the first one to notice this, but there's no way around it
