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download and database access speed Ranking mirrors This command will rank your mirrors by speed and will filter the out of date mirrors. pacman-mirrors -g You should sync the database after running this command by using: pacman -Syy 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 Sync the database pacman -Sy 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. pacman -Syy Updating Pacman can update your system with only one command: pacman -Su Although, it is usually better to sync your repo database first: pacman -Syu This command was recommend: pacman -Syyu Update & ignore a package The following changes take place in pacman's configuration file: /etc/pacman.conf IgnorePkg=package_name Update & ignore a package group IgnoreGroup=package_group Examples: IgnoreGroup=gnome IgnoreGroup=kde Installing Packages It is always best to have the repo databases synchronized & then all packages installed on your system up to date before you install any new packages. pacman -Syyu Install a package pacman -S 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 -S testing/package_name Install packages as a group pacman -S gnome pacman -S kde Force the installation of a package. Attention: Only for advanced users. pacman -S --force package_name 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: pacman -U http://www.examplepackage/repo/examplepkg.tar.xz Reinstall all packages pacman -S $(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 Removing Packages 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 Cleaning Packages 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. pacman -Sc Clean cache completely and remove all packages. Attention: This eliminates the possibility to Using Downgrade. pacman -Scc A safer way to remove old package cache files is to remove all packages except for the latest three package versions: paccache -rvk3 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 pacman -Q Find out which package owns a file pacman -Qo /file_path List all orphan packages with no dependencies pacman -Qdt List all installed packages from the AUR pacman -Qem View package dependencies. Use one of the following commands: pactree package_name 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 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 -S base-devel yaourt To use Yaourt to upgrade both official repos & AUR (only if new PKGBUILD files are available) use the following command: yaourt -Syua 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: yaourt -Qdt Packer 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: packer -Syu Support Following is a link to this page's forum counterpart where you can post any related feedback: http://forum.manjaro.org/index.php?topic=1705.0 Category: Contents Page Navigation menu Log inPageDiscussionReadView sourceView history Search Main page Recent changes Random page Help Tools What links here Related changes Special pages Printable version Permanent link Page information This page was last modified on 17 March 2016, at 15:44.
