Understanding Pacman

pacman is Arch's core package manager, handling installation, updates, and removal, automatically resolving dependencies. It utilizes .pkg.tar.zst packages from official Arch repositories.

Essential Pacman Commands:

1. System Update: Synchronizes your local database with online repositories and updates all installed packages.

   sudo pacman -Syu

2. Package Installation: Installs a package from the Arch repository. Replace package_name with the desired software.

   sudo pacman -S package_name

3. Package Removal (Keeping Dependencies): Removes a package, preserving shared dependencies.

   sudo pacman -R package_name

4. Package Removal (Removing Unused Dependencies): Removes a package and any orphaned dependencies.

   sudo pacman -Rns package_name

5. Package Search: Searches the repository for packages matching a keyword.

   pacman -Ss keyword

6. List Installed Packages: Lists all installed packages.

   pacman -Q

7. Package Details: Displays detailed information about a specific package.

   pacman -Qi package_name

8. Clear Package Cache: Removes outdated package files to free up disk space.

   sudo pacman -Sc

Exploring the AUR

The Arch User Repository (AUR) is a community-maintained repository of user-created packages (PKGBUILDs). These aren't officially supported but offer access to a vast range of software. Managing AUR packages directly is complex, hence the use of AUR helpers.

AUR Helpers: Streamlining AUR Management

AUR helpers simplify AUR package handling. Two popular choices are Yay and Paru.

1. Yay (Yet Another Yaourt): A popular helper combining pacman and AUR functionality.

Installation:

   sudo pacman -S --needed base-devel git
   git clone https://aur.archlinux.org/yay.git
   cd yay
   makepkg -si

Usage:

• Update (including AUR): yay -Syu
• Search: yay -Ss package_name
• Install: yay -S aur_package_name
• Remove: yay -R aur_package_name

2. Paru: Known for speed and simplicity.

Installation:

   git clone https://aur.archlinux.org/paru.git
   cd paru
   makepkg -si

Usage (similar to Yay):

• Update: paru -Syu
• Install: paru -S aur_package_name

Conclusion

pacman and AUR helpers are vital for Arch Linux users. pacman efficiently manages official repositories, while Yay and Paru unlock the extensive resources of the AUR, simplifying the process significantly.
