This Week in TUXEDO OS #06-2025 - TUXEDO Computers

Hello TUXEDO Fans and Open-Source Enthusiasts!

As the first rays of sunshine start melting the snow outside, our hardworking developer penguins are slowly thawing as well. After all, spring is just around the corner! And what better way to kick off the warmer months than with fresh updates?

This week, there are some exciting new additions to the TUXEDO OS repositories: VirtualBox receives a stability update, and the new NVIDIA driver boosts performance even further. Plus, we introduce you to Krusader, the big brother of Dolphin, and show you how zoxide can revolutionize navigation in the shell.

Enjoy reading,

KDE App of the Week: Krusader – Dolphin’s Big Brother

File managers are an essential part of any desktop environment. KDE Plasma offers one of the best file managers, Dolphin – not just on Linux but across systems. Its features cover all everyday file management tasks, and the dual-pane view makes working with files especially efficient.

What many don’t know: Dolphin has a big brother named Krusader, which celebrates its 25th anniversary in 2025. Krusader is available for Linux, Solaris, and other Unix-based systems like macOS and offers a highly powerful and extensible feature set. Like Dolphin, it supports protocols such as Fish, FTP, SFTP, SMB, NFS, and WebDAV through KIO, making it ideal for accessing remote file systems.

Features

• Powerful archive management with support for numerous formats
• Integration of mounted file systems (e.g., network shares)
• Advanced FTP support for server access
• Powerful search module with filtering options
• Internal file viewer and editor
• Folder and file comparison for synchronization and duplicate checking
• Command-based batch processing for renaming files
• Customizable interface and operation for maximum efficiency
• Root mode for administrative tasks (optional)

Krusader is highly configurable and offers a wealth of features that make it especially attractive to power users and advanced users.

Installation

In TUXEDO OS, you can easily install Krusader via the Discover App Store or directly from the console with:

sudo apt install krusader

You can find other KDE apps that were updated last week in the This Week in KDE Apps column.

TUXEDO OS Tips & Tricks: zoxide – the Smart Alternative to cd

Navigating through the file system is one of the most common tasks in the command line. However, constantly typing long paths with cd can be tedious. Zoxide comes to the rescue: This modern open-source tool replaces cd with intelligent navigation based on frequency and relevance. Inspired by z and autojump, zoxide remembers visited directories and enables lightning-fast switching with minimal input.

Installation

Zoxide is available for multiple platforms and can be easily installed on TUXEDO OS via the package manager. Typically, the tool is also included in the package repositories of other Linux distributions:

sudo apt install zoxide

After installation, Zoxide needs to be integrated into the shell. To do this, add the line:

eval "$(zoxide init bash)"

to the end of the configuration file for your shell. In the default configuration of TUXEDO OS, this file is ~/.bashrc. The following command will do this for you:

echo 'eval "$(zoxide init bash)"' >> ~/.bashrc

To apply the change immediately without needing to log out and back in, run:

source ~/.bashrc

Usage

Zoxide replaces cd with the z command. The advantage: You no longer need to type the full path – just a part of the name is enough, and zoxide will jump to the most relevant directory.

The first time you switch, you’ll need to type the full path so that zoxide can learn the directory:

z ~/Documents

From then on, a shortened command will be sufficient to jump to that directory at any time, no matter where you are in the system:

z Doc

Examples

Zoxide is especially useful in complex directory structures. For example, imagine you’re writing for the TUXEDO website and the news portal LinuxNews.de and organizing your drafts in the following structure:

tree TUXEDO --noreport
(out)TUXEDO
(out)├── articles
(out)├── discussion
(out)├── faq
(out)└── ideas
tree LinuxNews --noreport
(out)LinuxNews
(out)├── articles
(out)└── ideas

Instead of typing cd /home/user/TUXEDO/articles each time, after the first visit, a short command will do:

z art

Zoxide will jump to the directory you use most often. If you want to differentiate between multiple similar paths, simply add more key words:

z TUX art  # Switches to ~/TUXEDO/articles
z Li art   # Switches to ~/LinuxNews/articles

Zoxide is a powerful shell extension that significantly speeds up working with deeply nested directories. If you frequently switch between projects or data directories, Zoxide saves you valuable time. Once set up, switching directories becomes more intuitive than ever.
