xprop

xprop is a command line tool available in Unix-like operating systems that allows users to retrieve information about the properties of a graphical application window. It is widely used for debugging and inspecting graphical applications. The tool provides information about various properties, such as the window's class, title, size, position, and other attributes.

To use xprop, users can simply execute the command "xprop" followed by the options or target window as an argument. When the tool is activated, the user can click on any window to retrieve its properties in real-time. The output displays a list of properties, along with their names and values.

xprop is highly versatile and offers different options to filter and format the information it retrieves. Users can retrieve specific properties by passing their names as arguments, or they can use regular expressions to search for specific properties. Additionally, xprop supports exporting the output to a file or binding the output format to a specific action.

The tool is commonly used by developers and system administrators to troubleshoot graphical applications, identify issues with window management, or gather information about a window's properties for scripting purposes. It is especially useful for examining the properties of individual windows within a window manager.

Overall, xprop provides a convenient and efficient way to inspect and retrieve information about the properties of graphical application windows in Unix-like operating systems.
