Pacman for newbies
Who this post is for
- Users who are new to
- Someone who wants to see what other pacman users regularly use
What this post isn't
- Principle of pacman design
- Detail explanation of the commands
- Replacement of the documentation (duh!)
Everything in this post can of course be found easily using
pacman --help. But that's a documentation. It has a lot more than you'd ever need. This post will help you filter out the few good stuff (read: regularly used) from the vast documentation.
Here's a list of commands I personally use. I never had the need to use anything more than what's listed here.
- Upgrade local packages
sudo pacman -Syu
This command is probably the most used pacman command by quite some distance. It does 2 things
- downloads a fresh package list.
- upgrades all the installed pacakges that are out of date.
Pacman keeps a local copy of the package list in the system, so it doesn't have to download the list every time you run a command. The -y flag forces pacman to download a fresh copy of the package list from the repositories.
- Install packages
sudo pacman -S <package-name>
- Search for packages
sudo pacman -Ss <package-name>
- Remove packages
sudo pacman -Rns <package-name>
- Clean cache
sudo pacman -Sc
Still basics but rarely used
These are a list of commands that you probably wouldn't use on a daily basis.
- List all packages that are no longer required
- Remove all packages that are no longer required
sudo pacman -Rns $(pacman -Qdtq)
- Info of a package
pacman -Qi <package-name>
I use this command to look for a few things
- packages that require this package
- packages this package require
- whether it was installed explicitly
❯ pacman -Qi seahorse ... Depends On : gtk3 gcr ... Required By : None Install Reason : Explicitly installed
- List all the packages installed in your system
pacman -Q # To get the count pacman -Q | wc -l
- List packages that were explicitly installed
Packages come with dependencies. This is will only list those packages that you explicitly installed.
- List all the packages installed from aur
Not possible. But you can get a close to accurate result with
