Install and delete packages

Before installing and upgrading a software package, it is a good habit to synchronize the local package database with a remote software repository.
　　Pacman-syu
Or
　　Pacman -- Sync -- refresh
To install or upgrade a single software package or a column of software packages (including dependency packages), run the following command:
　　Pacman-s package_name1 package_name2
Sometimes in different software repositories, a software package has multiple versions (such as extra and testing ). You can choose one to install:
　　Pacman-s extra/package_name
Pacman-s testing/package_name
You can also synchronize the database package in a command and install a software package:
　　Pacman-sy package_name
Delete a software package and keep all installed Dependencies
　　Pacman-r package_name
Delete the specified software package and all dependencies that are not used by other installed software packages:
　　Pacman-Rs package_name
　　

Upgrade System

　　PacmanOnly one command can be used to upgrade all installed packages in the system. The upgrade time depends on how new your system is.
　　Pacman-su
Of course, the best practice is to combine the upgraded system and synchronized warehouse data into a command:
　　Pacman-syu
　　

Query the package Database

　　PacmanYou can use the-Q flag to search for and query the local package database. See
　　Pacman-Q -- Help
Or more detailed Pacman (8) manpage. Synchronous databases can be searched and queried using the-s mark. Or see the manpage or
　　Pacman-s -- Help
View Details.
　　

Other usage

　　PacmanIt is a very extensive package management tool. Here it is just some of its other main features.
Download the package without installing it:
　　Pacman-SW package_name
Install a local package (not from the source ):
　　Pacman-U/path/to/package/package_name-version.pkg.tar.gz
Clear the package cache completely (/var/Cache/Pacman/PKG ):
　　Pacman-SCC
Reinstall the installation package (packages that cannot be deleted due to dependency issues ):
　　Pacman-SF package_name
To learn more about the parameter switch, you can use Pacman -- help or man Pacman.

I always wanted to learn about the arch release, but because of the Optimus feature of my computer, the desktop system cannot be installed normally, and it needs to be carried out by a third-party Bumblebee. Fortunately, it has updated version 3.0 recently and plans to chew on arch again recently. In the hope of success, we hope to collect some information first.
