Arch Linux Maintenance Documentation

Published by marisabel on May 6, 2025

Generic commands for me to use.

1. Check disk usage and free space

To see how much space is used and available on each partition:

df -h

For more detailed usage on individual directories:

du -sh /*

To check specific folder usage, like your home directory:

du -sh /home/USER

2. Delete files in Trash

To clear the Trash:

rm -rf ~/.local/share/Trash/files/*

3. Remove unused packages and clean package cache

To remove orphaned packages (packages that were installed as dependencies but are no longer required):

sudo pacman -Rns $(pacman -Qdtq)

To clean the pacman package cache, removing old versions of packages:

sudo pacman -Sc

To remove all cached packages (careful with this as it removes all cached versions):

sudo pacman -Scc

4. Update the system

To update the system and all packages:

sudo pacman -Syu

5. List installed packages

To list all installed packages:

pacman -Q

To list only explicitly installed packages (packages you manually installed):

pacman -Qe

6. Check for broken packages

Sometimes, an update might break something. To check if there are any broken or incomplete packages:

sudo pacman -Qk

7. Remove unnecessary logs

Log files can accumulate over time. To remove systemd logs (be cautious, as this might remove useful logs):

sudo journalctl --vacuum-size=100M

To clear all logs, set a retention period (e.g., 1 week):

sudojournalctl --vacuum-time=1w

8. Remove unused dependencies (after uninstalling software)

When you remove software, there may be leftover dependencies that were installed with it but are no longer needed. Clean these up with:

sudo pacman -Rns $(pacman -Qdtq)

9. System Cleanup and Optimizing

You can also use debt of space in hidden configuration files or directories. This command cleans some space from orphaned packages or unneeded files (it’s safe to run occasionally but make sure to review packages first):

sudo pacman -Qdtq | sudo pacman -Rns -

10. Check your system for errors

Sometimes file systems can develop errors. You can check and repair them (if needed):

sudo fsck -A

For specific file systems (e.g., if you want to check /home):

sudo fsck /dev/sda3

11. Remove old kernels

If you’re using linux-lts or other kernel versions, they can take up a lot of space. Remove unused or older kernels:

sudo pacman -R linux-lts linux-lts-headers

12. Rebuild package database

Sometimes, the package database can become corrupt. If you face issues with package installation or updates, rebuild it:

sudo pacman -Syyu

13. Clear the font cache

To clear font cache and refresh it:

sudo fc-cache -f -v

14. Check running processes

To view the running processes and resource usage on your system:

top

Or for a more detailed view:

htop

15. Uninstall a package

If you need to remove a package completely (including dependencies that were installed with it):

sudo pacman -Rns <package_name>

16. View system logs

To see detailed logs of system activities, including errors or other logs:

sudo journalctl -xe

17. Check for available system updates

To check if there are updates without actually installing them:

sudo pacman -Qu

18. Checking and cleaning memory usage (swap)

To view swap usage:

swapon --show

To turn off swap (useful for troubleshooting or cleanup):

sudo swapoff -a

19. Free up system memory (clear cache)

To clear cached memory:

sudo sysctl vm.drop_caches=3

Managing MySQL (MariaDB) for Local Use on Arch Linux

Published by marisabel on April 19, 2025

So I can run small projects locally like journaling and stuff.

Installation

sudo pacman -S mariadb

sudo mariadb-install-db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

sudo systemctl enable mariadb

sudo systemctl start mariadb

sudo mysql_secure_installation

mysql -u root -p

Can’t login?

sudo mariadb

USE mysql;

ALTER USER 'root'@'localhost' IDENTIFIED VIA mysql_native_password USING PASSWORD('yourpassword');

FLUSH PRIVILEGES;

EXIT;

New User and Database

CREATE DATABASE mydb;
CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'mypassword';
GRANT ALL PRIVILEGES ON mydb.* TO 'myuser'@'localhost';
FLUSH PRIVILEGES;

Remove stylesheet.css from epub files with Linux

Published by marisabel on February 23, 2025

Problem:

I cannot use my own font when an open/not-DRM .epub has it’s own stylesheet being forced.

I have not tested this in DRM epubs. Though most modern ones will not have the stylesheet.css forced. So it should be fine.

Solution:

Remove the file using a zip application without extracting.

Script:

Move books to your Linux machine.

Install Zip: sudo pacman -S zip

Save this script as: remove_styles.sh 

#!/bin/bash

for epub in *.epub; do
    echo "Processing: $epub"
    zip -d "$epub" "*stylesheet.css"
done

Change permissions: chmod +x remove_styles.sh

Run: ./remove_styles.sh

Copy books again to your device.

Adobe Digital Editions via phone to Kobo Clara Colour

Published by marisabel on February 22, 2025 
🛑 This won’t damage your Kobo, but I’ve only tested it on the Kobo Clara Colour. I’m not responsible for any issues that may arise. This does not promote piracy in any way—the goal is simply to enable the use of DRM-protected ebooks legally on a Kobo, without a computer. Use at your own discretion.

Problem:

In the Netherlands, Libby and OneDrive aren’t connected, which means I can’t send files from Libby to my Kobo. Public Dutch libraries don’t even have Libby yet—Erasmus University Library only recently adopted it. Without OneDrive integration, I’m forced to transfer library ebooks to my Kobo using a USB cable (which feels rather primitive in 2025).

Adobe Digital Editions allows you to sync between devices (specifically Android and desktop only). It’s a free but outdated app, so improvements are unlikely. While I can download files to my ADE account via the Android app, I can only add them to my Kobo using a computer—not very convenient when borrowing books while on the road.

Solution I found after many tests:

On your phone, locate the Digital Editions folder and send the epub file to your Kobo—but only after authorizing both your phone and Kobo under the same account. The Kobo authorization must be done via computer, but you only need to do it once! The first steps are straightforward, but the last step is trickier without your own server. While Dropbox isn’t an option (even with modifications), I found that Google Drive works well. Though the process is technical, I’ll explain it as simply as possible.

Steps:

Follow this guide to get started with Adobe Digital Editions. (Important: NEVER open an ebook as “Anonymous”—you won’t be able to read it anywhere else.) Follow all steps to download Adobe Digital Editions, create an account, and authorize your e-reader.

Next, download Adobe Digital Editions for Android. Log in with the same account and authorize your device.

NickelMenu

KoboRoot⏬

Download KoboRoot.zip and extract KoboRoot.tgz (this updated version is compatible with Google Drive). (See this GitHub thread for the details).

Connect your Kobo to the computer and open the .kobo folder. Since it’s a hidden folder, you can either type it directly in the address bar or enable “Show Hidden Files” in your file explorer.

Copy the .tgz file to this location and safely disconnect your Kobo.

It will now update the device and you should see an empty extra menu on the right corner.

Connect the device again. Now comes the technical part.

Config files

Open this file: .kobo/Kobo/Kobo eReader.conf

Find the lines under [OneStoreServices] for google and edit them as follow:

googledrive_link_account_start=https://authorize.kobo.com/{region}/{language}/linkcloudstorage/provider/google_drive

kobo_googledrive_link_account_enabled=False

Then add a new folder and file here: .adds/nm/config

There is nothing else for that file, no txt, nothing, just config and save it.

Add this menu in that file (copy/paste):

menu_item :main    :Dark Mode     :nickel_setting :toggle :dark_mode
menu_item :main    :My Articles   :nickel_open: library: pocket
menu_item :main    :Screenshots   :nickel_setting :toggle :screenshots
menu_item :main    :GoDrive       :nickel_open :library :godrive

menu_item :reader  :Dark Mode     :nickel_setting :toggle :dark_mode
menu_item :reader  :My Articles   :nickel_open: library: pocket

menu_item :library :Dark Mode     :nickel_setting :toggle :dark_mode
menu_item :library :My Articles   :nickel_open: library: pocket

You can also just add the line:

menu_item :main    :GoDrive       :nickel_open :library :godrive

I just thought you might like others.

Now all you have to do is open the menu on the Kobo and connect to your Google Drive. From your phone, you can then upload the books from the Digital Editions folder to the folder in the drive and SYNC!

Happy reading!

Bookmarklets for Snippets

Published by marisabel on February 18, 2025 
javascript:(function(){ 
    let textToPaste = "MY SNIPPET"; 
    let field = document.activeElement;
    
    if (field && (field.tagName === "INPUT" || field.tagName === "TEXTAREA")) { 
        field.value += textToPaste; 
        field.dispatchEvent(new Event('input', { bubbles: true })); 
    } else { 
        navigator.clipboard.writeText(textToPaste).then(() => {
            alert("Text copied to clipboard! Paste it anywhere.");
        }).catch(err => {
            alert("Failed to copy text: " + err);
        });
    }
})();

If there’s an active text field, it pastes the text directly. Otherwise, it copies it to the clipboard so the user can manually paste it anywhere.

No alert version (you need to press CTRL+V after):

javascript:(function(){ 
    let textToPaste = "$x Vingerafdruk Controlleren "; 
    let field = document.activeElement;  

    if (field && (field.tagName === "INPUT" || field.tagName === "TEXTAREA")) { 
        field.value += textToPaste; 
        field.dispatchEvent(new Event('input', { bubbles: true })); 
    } else { 
        navigator.clipboard.writeText(textToPaste).catch(() => {}); 
    } 
})();

Selection and autopasting

            let start = activeElement.selectionStart;
            let end = activeElement.selectionEnd;
            let value = activeElement.value;
