our package manager
We have applications like pamac, discover or gnome-software to install software but there are also commands to do the same.
We urge you to learn the commands that are behind all the GUIs.
Installing Firefox is super simple.
sudo pacman -S firefox
Removing Firefox is super simple including dependencies if possible.
sudo pacman -Rs firefox
But you can do so much more with pacman.
Pacman operation : sync
|sudo pacman -S||sudo pacman -S firefox||Installs the package|
|sudo pacman -Sy||sudo pacman -Sy||Sync the pacman database|
|sudo pacman -Syy||sudo pacman -Syy||Sync the pacman database with force|
|sudo pacman -Syu||sudo pacman -Syu||Sync the pacman database and update|
|sudo pacman -Syyu||sudo pacman -Syyu||Sync the pacman database with force and update or update alias|
|sudo pacman -S … –noconfirm||sudo pacman -S –noconfirm firefox||Installs firefox – if confirmation is needed, always yes|
|sudo pacman -S … –needed||sudo pacman -S –needed firefox||Installs firefox if not yet installed – scripts|
|sudo pacman -Sc||sudo pacman -Sc||Cache clean – remove packages no longer installed|
|sudo pacman -Scc||sudo pacman -Scc||Cache clean – remove all files from cache|
|sudo pacman -Sg||sudo pacman -Sg xfce4||Show content of group package|
|sudo pacman -Si||sudo pacman -Si||Show info of package|
|sudo pacman -Sl||sudo pacman -Sl arcolinux_repo||Shows all packages in a repo|
|sudo pacman -Ss||sudo pacman -Ss awesome||Search in name and description anywhere|
Pacman operation : query
To query means to ask.
There are more flags possible here but remember that the Q stands for query. You can try these commands out without any harm. Replace foobar with Firefox for example.
sudo pacman -Q foobar
sudo pacman -Qs foobar
sudo pacman -Qi foobar
sudo pacman -Ql foobar
sudo pacman -Si foobar
If you found a file and you wonder what package has actually delivered this file then type this
sudo pacman -Qo /path/to/file_name
Pacman operation : File
There are more flags possible here but remember that the F stands for file. You can try these commands out without any harm. Replace foobar with Firefox for example.
sudo pacman -F foobar
sudo pacman -Fl foobar
The settings for pacman are kept in
We go in there to activate the test repositories for example.
There is an alias to change the content of this configuration file.
Your folder /etc/pacman.d/ holds two files.
Pacman needs to know where to get its files. These are the source files if you will.
- where can I find the packages for Arch Linux aka mirrorlist
- where can I find the packages for ArcoLinux aka arcolinux-mirrorlist
The content of arcolinux-mirrorlist is managed by ArcoLinux.
The content of mirrorlist is managed by our alias mirror and others.
It will get the fastest Arch Linux servers in your neighborhood.
Sometimes we run out of disk space. This mostly happens on dual boot systems.
You can clean out the cache folder and gain a few GB.
sudo pacman -Scc
Pacman stores the databases locally in /var/lib/pacman/sync/.
The pacman databases will occasionally get corrupted. Removing the files in this folder and updating your system will create new databases.
sudo rm /var/lib/pacman/sync/*
Type in the terminal this command
You will get all the important places pacman is going to use.
Root : /
Conf File : /etc/pacman.conf
DB Path : /var/lib/pacman/
Cache Dirs: /var/cache/pacman/pkg/
Hook Dirs : /usr/share/libalpm/hooks/ /etc/pacman.d/hooks/
Lock File : /var/lib/pacman/db.lck
Log File : /var/log/pacman.log
GPG Dir : /etc/pacman.d/gnupg/
Pacman and mirror
We have created several aliases to get the fastest Arch Linux servers in your neighborhood.
Pacman will download the packages from these servers.
They are all a little bit different and will result in a different mirrorlist in the /etc/pacman.d folder.
Then you can update your system and see if you are downloading faster than before.
Group and meta packages
In both cases the goal is to install a list of packages.
There are actually several packages in one group.
sudo pacman -S xfce4 xfce4-goodies
That is all that is needed to have a complete Xfce4 desktop.
Here you can find the list of all package groups.
Many of the desktops will have a group package to install a list of packages.
Follow the link above and find mate, mate-extra, plasma, xfce4 and xfce4-goodies and so many more.
These are the ones we also use in our cheatsheet on ArcoLinux.
You can not uninstall a group package.
If you do an Arch Way installation one of the first meta packages you will install are
pacman -S base
Read on the Arch Wiki about the difference between group and meta package.
Simply put, meta-packages are packages that do nothing but depend on other packages. The result of this is that you can install a group of packages at once by installing a single meta-package. Now, Arch Linux has a similar concept: package groups, and while they serve a similar purpose they are suitably different. The difference is when you add or remove dependencies – groups will not install/remove additional dependencies whereas meta packages will. When a dependency is added our system will install it automatically.
You can uninstall a metapackage.
Local help : read your “man pacman”
Type this command in the terminal
