Installing specific packages<\/p>\n
# pacman -S package_name1 package_name2 …<\/p>\n
To install a list of packages with regex<\/p>\n
# pacman -S $(pacman -Ssq package_regex)<\/p>\n
To install the version from the extra repository<\/p>\n
# pacman -S extra\/package_name<\/p>\n
To install a number of packages sharing similar patterns in their names one can use curly brace expansion. For example:<\/p>\n
# pacman -S plasma-{desktop,mediacenter,nm}<\/p>\n
This can be expanded to however many levels needed:<\/p>\n
# pacman -S plasma-{workspace{,-wallpapers},pa}<\/p>\n
Installing package groups<\/p>\n
# pacman -S gnome<\/p>\n
To see what packages belong to the gnome group<\/p>\n
# pacman -Sg gnome<\/p>\n
Removing packages<\/p>\n
To remove a single package<\/p>\n
# pacman -R package_name<\/p>\n
To remove a package and its dependencies which are not required by any other installed package<\/p>\n
# pacman -Rs package_name<\/p>\n
To remove a package, its dependencies and all the packages that depend on the target package (This operation is recursive, and must be used with care since it can remove many potentially needed packages.)<\/p>\n
# pacman -Rsc package_name<\/p>\n
To remove a package, which is required by another package, without removing the dependent package (The following operation can break a system and should be avoided.)<\/p>\n
# pacman -Rdd package_name<\/p>\n
Pacman saves important configuration files when removing certain applications and names them with the extension: .pacsave. To prevent the creation of these backup files use the -n option<\/p>\n
# pacman -Rn package_name<\/p>\n
Upgrading packages<\/p>\n
Pacman can update all packages on the system with just one command. This could take quite a while depending on how up-to-date the system is. The following command synchronizes the repository databases and updates the system’s packages, excluding “local” packages that are not in the configured repositories:<\/p>\n
# pacman -Syu<\/p>\n
Querying package databases<\/p>\n
Pacman queries the local package database with the -Q flag, the sync database with the -S flag and the files database with the -F flag.<\/p>\n
$ pacman -Ss string1 string2 …<\/p>\n
To search for already installed packages:<\/p>\n
$ pacman -Qs string1 string2 …<\/p>\n
To search for package file names in remote packages:<\/p>\n
$ pacman -Fs string1 string2 …<\/p>\n
To display extensive information about a given package:<\/p>\n
$ pacman -Si package_name<\/p>\n
For locally installed packages:<\/p>\n
$ pacman -Qi package_name<\/p>\n
Passing two -i flags will also display the list of backup files and their modification states:<\/p>\n
$ pacman -Qii package_name<\/p>\n
To retrieve a list of the files installed by a package:<\/p>\n
$ pacman -Ql package_name<\/p>\n
To retrieve a list of the files installed by a remote package:<\/p>\n
$ pacman -Fl package_name<\/p>\n
To verify the presence of the files installed by a package:<\/p>\n
$ pacman -Qk package_name<\/p>\n
Passing the k flag twice will perform a more thorough check.<\/p>\n
To query the database to know which package a file in the file system belongs to:<\/p>\n
$ pacman -Qo \/path\/to\/file_name<\/p>\n
To query the database to know which remote package a file belongs to:<\/p>\n
$ pacman -Fo \/path\/to\/file_name<\/p>\n
To list all packages no longer required as dependencies (orphans):<\/p>\n
$ pacman -Qdt<\/p>\n
To list all packages explicitly installed and not required as dependencies<\/p>\n
$ pacman -Qet<\/p>\n
Pactree<\/p>\n
$ pactree package_name<\/p>\n
Pactree: To view the dependency tree of a package<\/p>\n
$ pactree package_name<\/p>\n
