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
- You should sync the database after running this command by using:
Optimize the database access speed
For full benefit, run this command after syncing the database.
pacman-optimize && sync
Attention: This command defragments Pacman's database, which boosts performance on slow hard drives but is harmful on SSDs. So, do not use this command on SSDs!
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
Remove a package
pacman -R package_name
Remove a package with dependencies that are not being used by other packages
pacman -Rs package_name
Remove a package with all dependencies. Attention: The -c flag can remove needed dependencies, too. Only for advanced users.
pacman -Rsc package_name
- Remove a package and its configuration files too:
pacman -Rn package_name
Forcefully remove a dependency without removing any other package. Attention: Only for advanced users.
pacman -Rdd package_name
See Maintaining /var/cache/pacman/pkg for System Safety for an in depth view on this topic.
Cleaning the cache
- Leaves packages in your cache only for those packages which are currently installed on your system. Attention: This eliminates the possibility to Using Downgrade.
- 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)
If you get this error, don't worry: it means you don't have orphaned packages to remove!
error: no targets specified (use -h for help)
Searching for Packages
Provides a description of searched for package & associated packages
pacman -Ss package_name
Provides a description of previously installed package
pacman -Qs package_name
Provides detailed summary of a package
pacman -Si package_name
- Modified summary:
pacman -Qi package_name
- with 'ii' you can see the backup files and the date that the package has been changed.
pacman -Qii package_name
Get a list of installed packages
Find out which package owns a file
pacman -Qo /file_path
List all orphan packages with no dependencies
List all installed packages from the AUR
View package dependencies. Use one of the following commands:
pactree -c package_name
pactree -s -c package_name
AUR (Arch User Repository)
Following is info on three popular options for using the AUR, for a detailed list of their commands please look at their man pages:
Yaourt comes pre-installed with Manjaro so you normally won't have to install it. If you have removed it, this is how you install it again:
pacman -Syu base-devel yaourt
- To use Yaourt to upgrade both official repos & AUR (only if new PKGBUILD files are available) use the following command:
- To use Yaourt to download and rebuild the latest AUR packages from their source (regardless of PKGBUILD files):
yaourt -Syua --devel
You can use all Pacman commands mentioned on this Wiki page with Yaourt, too. One command is different:
- Removing orphaned packages is easier and more intuitive with Yaourt:
- Uses some of the same commands as pacman but differs in that it checks both the official repos & AUR.
yaourt -S packer
- Having installed 'packer' then you can run:
packer -S package_name
- This will upgrade from both official repos & AUR:
