Removing Packages

Warning: always review the package list before confirming when removing packages.
If you're not careful, you can easily remove the entire workspace due to dependencies.


Remove a package
     sudo pacman -R package


Removes all unnecessary dependencies from a package
     sudo pacman -Rc package


Pacman generally also creates backup configuration files when deleting packages. To
remove them, you can add 'n' to any of the examples above.
     sudo pacman -Rn package
     

     sudo pacman -Rsun package               
     

     sudo pacman -Rcn package


Lists installed packages that are not used by anything else and should no longer be needed.
     sudo pacman -Qdt     


Used to remove these packages mentioned above, that is, unnecessary packages, without dependencies
     sudo pacman -Rs $ (pacman -Qdtq)    


Installing Packages

Warning: never install a package without updating the system first. In a continuous version, this
can lead to a non-bootable system


Install a package
     sudo pacman -S package


However, installing a package without updating the system will lead to a partial authorization
situation, so to install smplayer, for example, the command is:
     sudo pacman -Syusmplayer


Install a local package
     sudo pacman -A package.pkg.tar.gz


To install a package directly from the local system or from a location on the internet
     sudo pacman -U package     


Warning: When using pacman -U, it's up to you to ensure that the package you are
installing is fully compatible with your system.

Download packages without installing


In some cases, it may be useful to download a package without installing. For example,
to install on a different system that is not connected to the internet. This can be done with:
     sudo pacman -Sw package


The package and any necessary dependencies will be downloaded to the pacman cache in var / cache / pacman / pkg.


Clearing the cache


To clear the cache of packages that are no longer installed
     sudo pacman -Sc


To clear the cache completely (USE CAREFULLY)
     sudo pacman -Scc


A safer way to remove old files from the package cache is to remove all packages except the three
most recent versions, using paccache
        paccache -rvk3
