This is a quick reference page which lists the most common commands used by Pacman and various popular wrappers. Please keep in mind that commands are not thoroughly explained in this Wiki page. Look here for more command explanation: Pacman Overview.
You may need root priviliges (via "sudo") when performing most of the commands given below.
Improve download and database access speed
Ranking your mirrorlist
Adding a number to -f/--fasttrack command will return a number of up-to-date and responsive mirrors
sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu
Optimize the database access speed
If you have a spinning disk drive (not an SSD!), run this command after syncing the database.
pacman-optimize && sync
Syncing and Updating
Commands for syncronising database
- You can force sync the database using the following command. It means, the database will be synced even if it's up to date. This is useful when you changed something repository related and want to have the changes take effect.
Commands for updating the system
Never use this command as it might result in partial updates:
The recommended way is to syncronize your repo databases first and the update:
If you have used pacman-mirrors to recreate the mirror list you must download the databases and the update:
Update & ignore a package It should not be necessary to use exclusion of packages. Such an exclusion might be the cause of the infamous partial updates.
- The following changes take place in pacman's configuration file: /etc/pacman.conf
Update & ignore a package group
Install a package
pacman -Syu package_name
- If for example you are using the testing repo, & you have that repo listed below your other repos in /etc/pacman.conf which should mean that an older package will take priority over the younger one in the testing repo, you should use pacman like this:
pacman -Syu testing/package_name
Install packages as a group
pacman -Syu gnome pacman -Syu kde
Download a package without installation
pacman -Sw package_name
Install a downloaded or a local package
pacman -U /package_path/package_name.pkg.tar.xz
- You can also use the URL:
Reinstall all packages
pacman -Syu $(pacman -Qqen)
To search which packages has been installed in a group
pacman -Sg gnome pacman -Sg kde
Get a full package list with versions. This will create a file called pacman.laptop in your home folder.
pacman -Q > ~/pacman.laptop

Cleaning the cache

- Clean cache completely and remove all packages. Attention: This eliminates the possibility to Using Downgrade.
- A safer way to remove old package cache files is to remove all packages except for the latest three package versions:
Cleaning orphan packages from the system. Also read Orphan Package Removal for further information.
pacman -Rsn $(pacman -Qdtq)
