About:
xwininfo is a command-line utility for the X Window System that retrieves and displays detailed metadata about existing windows. It provides essential information such as window geometry, ID, parent/child relationships, and visual properties. This tool is invaluable for developers and system administrators debugging GUI applications or scripting window management tasks.

Key Features:

Extracts window geometry (position, size, borders)
Displays window hierarchy (tree view of parent/child windows)
Outputs window IDs and visual properties
Supports tree mode for recursive window inspection

Use Cases:

Debugging X11 application window placement and sizing issues
Scripting automated window management or tiling operations
Gathering window IDs for use with other X11 utilities like xdotool

Alternatives:

xprop – xprop focuses on window properties and hints, whereas xwininfo focuses on geometry and hierarchy.
xdotool – xdotool can query window info but is primarily designed for simulating input and window actions.
