This Week in TUXEDO OS #14-2025 - TUXEDO Computers

Hello TUXEDO Fans and Open-Source Enthusiasts!

While others on social media debate whether tariffs on imported fish sandwiches will drive prices up for the average consumer on their ice floe or whether a hotdog is a sandwich, our hardworking developer penguins prefer to focus on the code! As Linus Torvalds aptly puts it:

Because if we have issues in the kernel development model, then social media sure as hell isn’t the solution. The same way it sure as hell wasn’t the solution to politics. – Linus Torvalds

Instead of endless debates, we deliver tangible innovations: tuxedo-tomte now runs in virtual machines, the kernel has been updated, and KDE Connect makes life between smartphone and desktop easier. Dive into the latest developments around TUXEDO OS!

Enjoy reading,
The TUXEDO OS Team

KDE App of the Week: Smartphone Pairing with KDE Connect

The open-source app KDE Connect is undoubtedly one of the flagship projects of the KDE community. It enables a secure and seamless connection between Android mobile devices and KDE desktops, as well as other devices.

The communication takes place exclusively via Multicast DNS in the local network, without transferring data to the cloud. Device pairing is initiated through a process similar to Bluetooth device pairing. The communication is always encrypted to ensure security and privacy.

What features does KDE Connect offer?

KDE Connect was originally developed by student Albert Vaka as part of the Google Summer of Code in 2013, and has since become an indispensable part of the KDE ecosystem. The app offers a variety of features that significantly simplify the exchange and control between devices. The key features of KDE Connect are:

• File Transfer – Files can be easily transferred between smartphones and desktops, as well as between different smartphones and PCs.
• Synchronization – Smartphone notifications are directly displayed on the desktop.
• Clipboard Sharing – Clipboard contents can be exchanged between smartphone and desktop.
• SMS and Calls – SMS messages can be read and replied to directly from the desktop. Calls can also be managed from the desktop.
• Media Control – Media playback on the PC is automatically paused when a call comes in.
• Device Search – The smartphone can be made to ring from the desktop. The phone’s battery status is also displayed directly on the desktop.
• Browser Integration – Control content like YouTube or Netflix from the smartphone. Links can be directly sent to the smartphone to open them there. For this, a browser extension must be installed.
• Remote Control – Use your smartphone as a touchpad or as a remote control for presentations.
• Remote Access – Send commands to your PC, such as locking the screen or shutting down the PC. With OpenVPN support, this is even possible outside the local network.

Availability of KDE Connect

KDE Connect is available not only for Linux but also for Windows, macOS, and FreeBSD. A limited version is also offered for iOS. Additionally, KDE Connect has been implemented as GSConnect for the GNOME Shell. The developer of GSConnect, Andy Holmes, has further made the app accessible for other GTK-based desktops like Xfce under the name Valent.

On TUXEDO OS, KDE Connect comes pre-installed. If it isn’t available on your system yet, you can easily install it via the Discover Software Shop or by using the terminal with the command sudo apt update && sudo apt install kdeconnect. The Android app can be found in both the F-Droid repository and the Google Play Store.

TUXEDO OS Tips & Tricks: Finding Files and Searching Contents

Efficient file searching is one of the most important skills for any Linux user. Whether it’s tracking down a specific file in a directory tree or searching for text within files, the command line offers powerful tools for these tasks. However, graphical applications can also be helpful in this regard.

Searching for Files with KFind

Users of the KDE Plasma desktop environment, as found in TUXEDO OS, can use the KFind program for file searching. It provides a simple yet powerful interface for specifically searching for files and folders.

Searching for Files by Name

After launching KFind, you can enter a search term in the Name/Path tab and specify the directory to search in. This allows you to quickly find specific files without resorting to the command line.

Searching for Content Within Files

In the Content tab, KFind allows you to search for specific words or phrases within files—similar to grep in the command line. Regular expressions can also be used for more complex searches.

Using Advanced Filtering Options

Additionally, KFind allows you to narrow your search by date, file size, and other criteria, which is particularly useful when searching through many files in a large directory tree.

Searching for Files with find in the Terminal

The find command searches the file system recursively in the terminal for files and directories based on various criteria, such as name, size, or modification date. Below are some examples. The full syntax can be found, for example, in the man page, which can be accessed via man find.

Searching for Files by Name

This command searches the /home directory and all subdirectories for files (option -type f) that end in .txt.

find /home -type f -name "*.txt"

Searching for Files Case-Insensitive

The option -iname ensures that case differences are ignored.

find /home -type f -iname "report.txt"

Searching for Files by Size

Here, all files in /var/log larger than 100 MB are searched for.

find /var/log -type f -size +100M

Searching for Files by Modification Date

Files modified within the last 7 days:

find /home -type f -mtime -7

Files modified more than 30 days ago:

find /home -type f -mtime +30

Automatically Deleting Found Files

With find, you can also apply actions directly to search results. The following command deletes all .log files in the /tmp directory that are older than 7 days.

find /tmp -type f -name "*.log" -mtime +7 -delete

Quickly Finding Files with locate

Unlike find, locate works with a pre-built database, which significantly speeds up searches.

Updating the Database

Since locate relies on an index database, it needs to be updated regularly:

sudo updatedb

Quickly Searching for Files

locate report.txt

This command instantly shows all paths where a file named report.txt is found.

Displaying Only Existing Files

If the locate database is outdated, it may show files that no longer exist. Use -e to list only actually existing files:

locate -e document.pdf

Showing Only Files from the Home Directory

Locate itself does not offer a way to filter the output and show only search results from specific directories. However, the output can be quickly filtered using grep:

locate example.txt | grep '^/home/'

Searching for Content Within Files

Sometimes, the filename is unknown, but the text contained in the file is known. This is where grep comes into play.

Simple Text Search

This command shows all lines in /var/log/syslog that contain the word „Error.“

grep "Error" /var/log/syslog

Recursive Search in Directories

With -r, the entire /var/log directory is searched for the term „error message.“

grep -r "error message" /var/log/

Case-Insensitive Search

The -i option ensures that „warning“, „Warning“, or „WARNING“ will be found.

grep -i "warning" /var/log/syslog

Displaying Line Numbers

This command shows the line number before each match.

grep -n "exception" error.log

Showing Only Filenames Containing the Search Term

This will only display the names of files containing „ERROR.“

grep -l "ERROR" *.log

With KFind, find, locate, and grep, TUXEDO OS offers powerful tools to quickly find files or search contents. While find is flexible and universally applicable, locate excels in speed. Grep perfectly complements these tools when it comes to finding text within files. With these tools, the workflow in the Linux console and KDE environment can be made efficient.
