How to Use the Command 'kdocker' (with examples)

KDocker is a versatile command-line utility that allows users to easily dock any running application window to the system tray. This can help keep your desktop uncluttered, manage applications more efficiently, and provide quick access to frequently used programs. KDocker can be particularly useful for those who work with numerous applications simultaneously and need a tidy workspace. Below are several use cases demonstrating how to utilize KDocker in different scenarios.

Use Case 1: Display a Cursor to Send a Window to the System Tray

Code:

kdocker

Motivation:

This use case allows users to manually choose which application window to send to the system tray, offering flexibility when managing desktop space. It’s particularly helpful when running multiple applications and deciding on the fly which one you’d like to minimize and access quickly later on.

Explanation:

The command kdocker on its own does not specify any particular application. Instead, it activates a mode where your mouse cursor will change, usually to a crosshair. You can then click on any open window, and KDocker will send it to the system tray. If you press any other mouse button, the action is canceled, providing a safe and reversible way to dock windows.

Example Output:

After running the command, your cursor changes, allowing you to click on any window. Once clicked, the window disappears from the desktop and is now an icon in the system tray, keeping your workspace clean while maintaining easy access to the application.

Use Case 2: Open an Application and Send It to the System Tray

Code:

kdocker application

Motivation:

This scenario is useful for launching and instantly minimizing an application you want running in the background without cluttering your desktop. Such situations might include messaging apps, music players, or any utility programs.

Explanation:

By specifying an application after kdocker, you instruct the command to launch the application and immediately dock it to the system tray. The name of the application should be the command that you usually use to start it. This process helps maintain focus on the task at hand by keeping your desktop organized and reducing distractions.

Example Output:

Running this command opens the specified application and briefly displays its window before minimizing it directly to the system tray. The application runs as normal, but you will only see its icon in the tray, allowing for quick re-access.

Use Case 3: Send Focused Window to the System Tray

Code:

kdocker -f

Motivation:

When you have a specific window to dock that’s currently in focus, this command offers a direct method to quickly minimize it to the system tray without additional mouse interactions. It’s efficient in a multitasking environment.

Explanation:

The -f flag stands for “focused,” meaning KDocker will take the window currently selected in your operating system as the one needing docking. This eliminates the need to select the window manually, speeding up your workflow.

Example Output:

Executing this command immediately sends the focused window to the system tray. The application is still running, but its interface is hidden, and you can restore it by clicking its icon in the tray.

Use Case 4: Display a Cursor to Send a Window to the System Tray with a Custom Icon

Code:

kdocker -i /path/to/icon

Motivation:

This use case is ideal if you are particular about the aesthetics of your system tray. By assigning a custom icon, you can easily identify the application among other tray icons, especially useful for those who prefer a personalized workspace.

Explanation:

The -i option lets you specify a path to an image file that KDocker should use as the icon instead of the application’s default one. This customization option is helpful for distinguishing between different docked windows, particularly when using multiple instances of the same application.

Example Output:

Once you execute the command and choose a window, that window is minimized to the system tray, represented by your chosen icon. This allows quick identification and enhances the visual appeal of your tray icons.

Use Case 5: Open an Application, Send It to the System Tray and If Focus Is Lost, Minimize It

Code:

kdocker -l application

Motivation:

This mode is beneficial for applications you want open but not constantly visible, minimizing them automatically whenever you switch tasks. It’s great for persistent background tasks, ensuring they stay out of sight unless you’re actively using them.

Explanation:

The -l flag tells KDocker to “lose focus” after launching the application. This means the window will dock to the system tray whenever it’s not currently selected, optimizing your workspace efficiency by seamlessly de-cluttering your desktop.

Example Output:

When you run this command, the application opens normally. As soon as you shift focus to another application or window, KDocker minimizes the application to the system tray, maintaining it in the background.

Use Case 6: Display Version

Code:

kdocker --version

Motivation:

Knowing the version can help verify compatibility or determine if you need an update, especially when troubleshooting or reporting issues to developers.

Explanation:

The --version flag prompts KDocker to output its current version number. This is a common flag with many command-line tools, providing pertinent software information in a concise manner.

Example Output:

Running this command will output something like KDocker version 5.2.1, allowing you to verify your tool’s version.

Conclusion:

KDocker is a powerful utility for managing your workspace by docking application windows to the system tray. Each use case provides tailored functionality, allowing users to keep their desktop organized, customize their environment, and efficiently handle running applications. Whether you’re looking to reduce distractions, personalize your system tray, or manage focus dynamically, KDocker offers flexible solutions to enhance your productivity.
