This Week in TUXEDO OS #27-2025 - TUXEDO Computers

Hello TUXEDO Fans and Open-Source Enthusiasts!

Over 95 degrees in the shade and no rain in sight? Not exactly ideal penguin weather! Still, our developer Tuxes remain alert: all updates against the chwoot exploit in sudo have been integrated into TUXEDO OS. Fresh packages are also available for Tomte, the TUXEDO drivers, as well as Firefox, Thunderbird, and Chromium. Plus, we take a look at the lightweight image viewer Photos and introduce alternatives to the classic Linux commands cat and ls: bat and lsd.

Enjoy reading,

KDE App of the Week: The Fast Image Viewer Photos

If you’re looking for a lightweight, fast, and user-friendly program to browse your photos, take a look at KDE Photos: a minimalist image viewer from the KDE software suite KDE Gear.

With its clean interface and focus on the essentials, Photos is ideal for anyone who simply wants to view their images – without complex menus or bloated features. The name Photos is a recent change; originally, the app was called Koko. For that reason, the installation package is still named “koko”.

The Strengths of KDE Photos

KDE Photos features a deliberately minimalistic interface. When you open an image, it takes center stage. In addition to individual images, you can open entire folders and conveniently browse through your photo collection using the arrow keys or mouse wheel.

The app is fast, lightweight on resources, and well-suited even for low-powered hardware. It automatically adapts to your system’s light or dark theme.

Photos is based on Kirigami, KDE’s framework for convergent applications. This means the app runs not only on traditional PCs and laptops, but also on mobile touchscreen devices. In addition, Photos offers basic image editing tools such as cropping, resizing, rotating, and mirroring.

Installing Photos on TUXEDO OS

Photos is not preinstalled on TUXEDO OS, but you can easily install it via Discover or from the terminal:

sudo apt install koko

You don’t always need a full-featured heavyweight. Quite the opposite: if you just want to view your photos quickly and without distractions, Photos is the perfect tool for your TUXEDO OS desktop.

TUXEDO OS Tips & Tricks: Discover Modern Command-Line Tools

In this issue of our TUXEDO OS Tips & Tricks, we introduce two useful alternatives to the traditional command-line tools cat and ls: bat and lsd. Both offer extended features and improved usability, making working on the command line more efficient.

Installation on TUXEDO OS

Installing bat and lsd on TUXEDO OS is very straightforward and follows the same procedure as on Ubuntu, Debian, or Linux Mint. You can easily install both programs via the terminal. To do so, enter the following commands:

sudo apt install bat
sudo apt install lsd

After installation, you’ll notice that the command to launch the program is batcat. This is because the name of the executable bat would otherwise conflict with the backup software Bacula, which also includes a program named bat. To avoid confusion, the developers of bat chose the name batcat.

To use bat comfortably via the cat command without typing the longer batcat, you can create an alias in your shell configuration file (e.g., in the ~/.bashrc file in your home directory). You can also use lsd via alias instead of ls. Add the following lines:

alias cat='batcat'
alias ls='lsd'

### Optional
# alias l='ls -l'
# alias la='ls -a'
# alias lla='ls -la'
# alias lt='ls --tree'

Save the file and restart your terminal or run source ~/.bashrc to apply the changes.

Usage and Benefits

Both bat and lsd are designed to extend the standard functionality of their predecessors while offering a more modern user experience—without sacrificing compatibility.

bat – cat with wings

bat is a cat clone with syntax highlighting and Git integration. When viewing text files or code on the command line, bat provides colorful syntax highlighting for a wide variety of programming and configuration file formats.

This makes it much easier to quickly understand the structure and content of a file. Additionally, bat shows Git changes directly in the terminal – an especially useful feature for developers. Integrating these capabilities into the command line saves time and greatly improves readability.

By default, bat pipes its output to a pager (similar to less) if the content exceeds one screen. This ensures that even large files can be viewed comfortably, line by line, using the arrow keys to scroll.

If you want bat to always behave like cat and never invoke a pager view, you can use the batcat –paging=never option. This can be set either directly on the command line or permanently in your config file at ~/.config/bat/config. If you define cat as an alias for batcat in your shell configuration, it is recommended to use:

alias cat='batcat --paging=never'

…to retain the default behavior of cat.

Even when a pager is enabled, you can still use bat for concatenating files. If bat detects a non-interactive terminal—for example, when redirecting output to another process or file – it behaves as a direct replacement for cat. In this case, bat outputs raw file content regardless of the paging option setting.

batcat datei1.txt datei2.txt > merged.txt

lsd – List Directories Deluxe

lsd (LSDeluxe) is a modern alternative to ls, displaying file lists with icons, colors, and tree views. While ls provides a simple list of files and directories, lsd presents output that is more visually appealing and informative.

Using icons, you can immediately identify whether an item is a file, directory, symlink, or executable. Color coding also helps to distinguish file types or permissions.

wget https://github.com/ryanoasis/nerd-fonts/releases/download/v3.4.0/Hack.zip
unzip Hack.zip
sudo mkdir -p /usr/local/share/fonts
sudo mv *.ttf /usr/local/share/fonts
fc-cache -fv

One especially useful feature is the ability to display directory contents as a tree view using the lsd –tree command. This simplifies navigation through complex directory structures and gives a better overview. These visual improvements help reduce errors and boost efficiency when managing files.
