似乎没有窗口的PID。你如何杀死这个无PID窗口？

Question

我正在尝试获取此图像右侧的窗口“A：流体流动（流畅）-网格划分”的 PID 。我找到的命令如下。单击窗口后，它们不起作用。我想杀死来自左侧窗口“Test02 - workbench”的右侧窗口，而不杀死两个窗口。通过双击位于右侧窗口的 Geometry 和 Setup 之间的 Mesh 获得右侧窗口。但是，我能够获得左侧窗口的PID。

$ xprop _NET_WM_PID
_NET_WM_PID:  not found.

$ xprop _NET_WM_PID | cut -d' ' -f3
not

$ xprop
_NET_WM_ICON_GEOMETRY(CARDINAL) = 5, 694, 54, 54
_NET_FRAME_EXTENTS(CARDINAL) = 0, 0, 28, 0

        window state: Normal
        icon window: 0x0
_NET_WM_DESKTOP(CARDINAL) = 0
_NET_WM_STATE(ATOM) = _NET_WM_STATE_MAXIMIZED_VERT
WM_CLASS(STRING) = "Ansyswbu.exe", "MainWin"

$ wmctrl -mlpx

...

使用最后一个命令wmctrl -mlpx，似乎左侧窗口的PID为5159，右侧窗口的PID为0。怎么可能是0？

谢谢。

Answer 1

它与 wmctrl 和窗口 id 一起使用。

首先，如果没有 wmctrl，请安装它：

sudo apt-get install wmctrl

其次，找到窗口 ID：

$ wmctrl -mlpx
...
0x046000a4  0 0      Ansyswbu.exe.MainWin    N/A    A : Fluid Flow (Fluent) - Meshing [ANSYS Academic Research]
...

最后，用空 PID wmctrl杀死野兽：

wmctrl -ic 0x046000a4

Answer 2

你想要的命令是：

xprop | grep _NET_WM_PID
