I recently revived one of my older MacBooks ( an early 2013 13″ pro ) by installing Ubuntu 20.04 to it.
We are dealing with an older laptop, still running on its original battery; because of that, I decided to look for a terminal program that would provide me with the kind of information I like to get from a terminal app, and with the “sci-fi” look I am keen to have as much as possible (but still being lightweight )
I found this tiny jewel to add to my “top” commands collection (btop, htop, duf, etc.). https://github.com/svartalf/rust-battop
You can visit the releases page (https://github.com/svartalf/rust-battop/releases) and get the correct version.
I am running 64bit Ubuntu on an intel mac from 2013, so I picked up this one: https://github.com/svartalf/rust-battop/releases/download/v0.2.4/battop-v0.2.4-x86_64-unknown-linux-gnu.
All you have to do afterwards is to install the binary in the right place. I will leave you here my example:
# sudo install ./battop-* /usr/local/sbin/battop
