Arch Linux How to Check Installed Packages
If you are running Arch Linux you have, at some point, probably wanted a way to check which packages are installed on your system. As you would expect, it is very easy to generate a list of packages.
This command will list all installed packages:
pacman -QThis will generate a list of explicitly installed packages:
pacman -Qqe > my-list-of-packages.txtList explicitly installed packages that aren’t already a dependency of other explicitly installed packages:
pacman -Qqe > my-list-of-packages.txtList of foreign packages. This includes things from AUR:
pacman -Qqem > my-foreign-package-list.txtHere are some relevant switches:
| -Q | query package db |
| -e | only show explicitly installed packages |
| -t | exclude anything that is a dependency of an explicitly installed package |
| -n | exclude foreign packages including AUR packages |
| -q | quiet, show less information |
Install packages from a list that are not already installed and up-to-date:
pacman -S --needed - < my-list-of-packages.txtReferences
