pacman-sync: Remove not installed packages and unused repositories from the cache (use two `--clean` flags to clean all packages).
$ sudo pacman --sync --clean
try on your machine
This command:
sudo pacman --sync --clean
is used in the Pacman package manager on Arch Linux or Arch-based distributions. Here's what it does:
- sudo: This command is used to run the subsequent command with root or administrative privileges. It prompts the user to enter their password to verify the elevated access.
- pacman: This is the package manager utility used on Arch Linux. It is responsible for installing, updating, and managing software packages.
- --sync: This option tells Pacman to synchronize the package database with the remote repositories, checking for updates and new packages.
- --clean: This option prompts Pacman to remove any packages that are no longer installed on the system. It clears the package cache, freeing up disk space used by previously downloaded packages that are no longer needed.
So, overall, the command "sudo pacman --sync --clean" updates the package database and removes unnecessary packages to keep the system clean and up to date.
