would be nice to know what do you really need.
the command last is used to check who is/was logged in (see man page).
The directory /var/log contains logs, you can check its content, you can read it with a normal editor (or with less).

You must spend time web-searching each specific topic.
Start each specific search with the two keywords: Linux tutorial
followed by whatever specific info you want.
Often, great articles are found by adding the keyword: wiki

https://www.linux.com/learn/sysadmin...s-command-line

Also, try a command like: man -k last
