# You can't directly install packages from the Arch User Database (AUR) with pacman.
# You need yaourt to perform that. But considering yaourt itself is in the AUR, here is how to build a package from its tarball.
# Installing a package from AUR is a relatively simple process:
# - Retrieve the archive corresponding to your package from AUR website
# - Extract the archive (preferably in a folder for this purpose)
# - Run makepkg in the extracted directory. (makepkg-s allows you to install any dependencies automatically from deposits.)
# - Install the package created using pacman
# Assuming $pkgname contains the package name.
wget "https://aur.archlinux.org/packages/${pkgname::2}/$pkgname/$pkgname.tar.gz"
tar zxvf "$pkgname.tar.gz"
cd "$pkgname"
# Build the package
makepkg -s
# Install
sudo pacman -U <package file (.pkg.tar.xz)>

# Arch Linux sort installed packages by size - This version accounts for the MiB/KiB suffix output by pacman these days.
pacman -Qi | grep 'Name\|Size\|Description' | cut -d: -f2 | paste - - - | awk -F'\t' 'BEGIN{ s["MiB"]=1024; s["KiB"]=1;} {split($3, a, " "); print a[1] * s[a[2]], "KiB", $1}' | sort -n

pacman -Fs libusb-0.1.so.4
# Arch Linux: Search for missing libraries using pacman If, while using a program, you get an error similar to: error while loading shared libraries: libusb-0.1.so.4: cannot open shared object file: No such file or directory Use pacman or pkgfile to search for the package that owns the missing library https://wiki.archlinux.org/index.php/General_troubleshooting#Message:_%22error_while_loading_shared_libraries%22 Show Sample Output:
        # extra/libusb-compat 0.1.5-1
