Keeping the details about vim in the extras is what I would do as well, but I would definitely tell the students that vim and vi exist, because they are the only editors available on many systems.

I would consider that ifconfig is deprecated on many distros and would therefore teach about iproute2 (mostly the ip and ss commands) instead. Additionally I would consider editing files essential, even if it is with nano.

Maybe mention more modern and simpler help tools like tldr, as they could be even more useful to beginners.

To introduce the shell and utilities, I would try to find a somewhat realistic use case that combines multiple aspects, like analyzing some files or spellchecking instead of simply mentioning every feature one by one.

Why not write your own version? Getting the temperatures is easy and portable with the sensors command from lm-sensors. The rest of the info is easy to get using various commands (e.g. uptime, free) combined with a bit of sed/grep/awk for formatting.
