Gonna throw finger into the mix?
oh, I never used finger before, thank you Ben for sharing this.
Seems it doesn't come with the default shell commands set, need to do apt install finger, and the output seems similar to w? Can you share more of the benefits using it compare to w if you don't mind?
apt install finger
It used to be used all the time, but it's fallen out of favour. It's insecure, it was a plain-text client-server system so you could say finger firstname.lastname@example.org or even just finger @scramble and it would interrogate the finger daemon on that host. If you set a file in your home directory called .plan it would display as part of the finger output:
$ finger teasmade@scramble.
Login: teasmade Name: Teasmade
Directory: /home/teasmade Shell: /bin/bash

There's a good overview of it here: computerhope.com/unix/ufinger.htm
Benefits include being able to query remote hosts, and being able to control what people can see about you by editing files in your home.
There's also the last command, which will give a listing of who was logged in:
moopet pts/0 192.168.0.16 Sun Aug 4 19:20 - 19:21 (00:01)
moopet pts/0 192.168.0.16 Sun Aug 4 19:19 - 19:20 (00:00)
reboot system boot 5.2.5-arch1-1-AR Sun Aug 4 18:49 - 13:32 (10+18:43)
moopet pts/0 192.168.0.16 Sun Aug 4 17:40 - 17:40 (00:00)
moopet pts/0 192.168.0.16 Sun Aug 4 17:39 - 17:39 (00:00)
root tty1 Sun Aug 4 17:32 - 17:42 (00:09)
reboot system boot 5.2.5-arch1-1-AR Sun Aug 4 17:32 - 17:42 (00:09)
I see, "being able to query remote hosts" this would be useful in some cases, gonna read more on it, thank you Ben :D
