Great, "screen -S session -Q number" is exactly what I want.

Thanks to FLJ for the tip and yes, Neal's clarification about "focus" vs "visible" is correct, the thing I actually is the number of the window who has the focus now.

Also IIRC the number command gives the number of the process which has focus - if you use splits more than one may be visible, but only one has focus at a time.

Hello  Xiaopan,

perhaps I misunderstood, but at least on recent version of Ubuntu, Raspbian and OpenWrt you have:

 -Q   Some  commands now can be queried from a remote session using this
            flag, e.g.  "screen  -Q  windows".  The  commands  will  send  the
            response  to  the  stdout of the querying process. If there was an
            error in the command, then the querying process will exit  with  a
            non-zero status.

            The commands that can be queried now are:

$ screen -S pts -Q number
$ screen -S pts -Q windows

Hi there,

In short:
If a screen session has multiple windows, does any one know how to tell the number of the current visible window?

In long:
As I explained in this thread, I have two monitors running two screen sessions, and a vim window in one and bash in the other, and I am using screen '-X stuff' command to send shell commands from the vim window to the bash window to execute them. Because the screen session in which the bash lives might have multiple windows, I want to make sure the bash window receiving commands is visible and if it is not, explicitly switch to that by selecting them. However, if a window is already selected, selecting it again causing an annoying message box and a pause in the screen display, so I want to avoid selecting already selected window. I know the window number where the bash runs, but how can I get the current visible window number?
