## 常用
pacman -Qe # List all explicitly installed packages
pacman -Qet # list all packages explicitly installed and not required as dependencies
pacman -Qent # List all explicitly installed native packages (i.e. present in the sync database) that are not direct or optional dependencies
pacman -Qn # List all native packages (installed from the sync database(s))
pacman -Qm # List all foreign packages (typically manually downloaded and installed or packages removed from the repositories)

sudo pacman -Qtdq | sudo pacman -Rns - # recursively removing orphans and their configuration files

sudo pacman -Qii | awk '/^MODIFIED/ {print $2}' # print modified files under /etc

pacman -Qs regex # List packages by regex

pacman -Qg group_name # List installed packages under this group
pacman -Sg group # List all packages in the package group named `group`, etc, base-devel, gnome
pacman -Slq | rg <package> # search package_name
pacman -Qq | grep -Ee '-(bzr|cvs|darcs|git|hg|svn)$' # list all development/unstable packages
pacman -Syu # Update package list and upgrade all packages afterwards
pacman -Syu git # Update package list, upgrade all packages, and then install git if it wasn’t already installed

pacman -S package_name1 package_name2 # Installing specific packages
pacman -S $(pacman -Ssq package_regex) # Install a list of packages with regex
pacman -S extra/package_name # Install specific repositories' package
pacman -S plasma-{desktop,mediacenter,nm}
pacman -S plasma-{workspace{,-wallpapers},pa}

pacman -S gnome # Install through group of packages
# Enter a selection (default=all): 1-10 15 # which will select packages 1 through 10 and 15 for installation
# Enter a selection (default=all): ^5-8 ^2 # which will select all packages except 5 through 8 and 2 for installation

pacman -R package_name # remove a single package, leaving all of its dependencies installed
pacman -Rs package_name # remove a single package and its dependencies which are not required by any other installed package

pacman -Qtd # check for packages that were installed as a dependency but now, no other packages depend on them

pacman -Ss string1 string2 ... # search for packages in the database
pacman -Qs string1 string2 ... # search for already installed packages
pacman -F string1 string2 ... # search for package file names in remote packages
pacman -Fy string1 string2 ... # first flush local cache, then search for package file names in remote packages

pacman -Si package_name # display extensive information about a given package
pacman -Qi package_name # display extensive information about locally installed packages
pacman -Qii package_name # also display the list of backup files and their modification states

pacman -Ql package_name # retrieve a list of the files installed by a package
pacman -Fl package_name # retrieve a list of the files installed by a remote package

# 批量删除 Pacman 包
sudo pacman -Rs $(pacman -Qq | grep some_words)
# https://bbs.archlinux.org/viewtopic.php?pid=1533162#p1533162

## Rarely use
pacman -Qk package_name # verify the presence of the files installed by a package, Passing the k flag twice will perform a more thorough check
pacman -Qo /path/to/file_name # query the database to know which package a file in the file system belongs to
pacman -Qo command_name # 找到所属包
pacman -F /path/to/file_name # query the database to know which remote package a file belongs to

pacman -Sy # never run!!!
pacman -Rdd package # never run!!!
