Ubuntu host configuration commands

I have been using the Ubuntu System for so long, but I still focus on simple use. Many commands on system settings are rarely used at ordinary times. When I read a book, I forget it, it is very troublesome to search again when it comes to use. Today, we will record some of the commands we need to solve when we encounter problems, which will also facilitate future memories and queries.

I have learned this knowledge from others' blogs, and I need to write some original knowledge when I have accumulated more.
