pacman, the package manager for RebornOS keeps packages in cache so if they need to be reinstalled its quick and easy but sometimes they tend to collect some big packages that are mostly not needed they are stored in
/var/cache/pacman/pkg/ you can see how big the cache is by running
du -sh /var/cache/pacman/pkg/. There are two ways of reclaiming that space Manually or Automatically.
One option is to remove cached packages that are not currently installed:
sudo pacman -Sc
Another way to clean the
/var/cache/pacman/pkg/ directory is to use a script that automatically deletes all cached versions of installed and uninstalled packages, except for the most recent 3 versions. The script is called
paccache. You can install it with the
pacman-contrib package -
sudo pacman -S pacman-contrib
You can run
paccache every time after you run
pacman. So, you need to create a Hook for that. Just create a file
sudo nano /usr/share/libalpm/hooks/paccache.hook
Add this content into the file, then press Control S and Control X
[Trigger] Operation = Upgrade Operation = Install Operation = Remove Type = Package Target = * [Action] Description = Cleaning pacman cache with paccache … When = PostTransaction Exec = /usr/bin/paccache -r
Every Linux distribution has a logging mechanism that help you investigate what’s going on your system. You’ll have kernel logging data, system log messages, standard output and errors for various services in RebornOS. The problem is that over the time, these logs take a considerable amount of disk space. You can check the log size with this command:
Now, there are ways to clean systemd journal logs. The easiest for you is to clear the logs that are older than a certain days.
sudo journalctl --vacuum-time=3d

As we use our system, the cache will fill up and take up a lot of space. So, the first thing you probably would want to do is to clean cache in your user directory. If you want to check the size of your cache folder you can do it with this command:
sudo du -sh ~/.cache/
To clean it you need to remove all files inside it:
rm -rf ~/.cache/*
And that is it.
You can check what the largest files in your system are and maybe you do not need them. To accomplish this task, you can use some command line tools or graphical programs.
