Practical Tips: Install and delete a command set in Ubuntu

I installed Ubuntu for the first time. I used to play redlinux and red-flag Linux before. I felt that some operations were troublesome, but I was not very familiar with it. I installed Ubuntu this time, I think Ubuntu is indeed very successful. At least, there are a lot of help information on the Internet, so I can easily understand the installation of Ubuntu, and there is an apt command under Ubuntu, you can run a command to install and delete the installed program without downloading, decompressing, and making the program on the website.
