xprop 命令

常用示例

说明

xprop displays properties of X Window System windows. Properties are arbitrary data that applications and window managers use to communicate, such as window titles (WM_NAME), window classes (WM_CLASS), and window states. When invoked without -id, -name, or -root, xprop displays a crosshair cursor allowing interactive window selection by clicking. Specific properties can be listed as arguments to display only those. Common properties include WM_NAME (title), WM_CLASS (application class), WM_STATE, _NET_WM_PID, and various Extended Window Manager Hints (_NET_WM_*).
