how to detect whether a laptop is docked

how to detect whether a laptop is docked

[Nellis, Kenneth]

Dear Cygwin Users:

I am looking for a method by which I can determine within a shell script 
whether my laptop is docked or not. Google provided some answers for Linux 
and Windows users, but the several ways I tried did not work out.

One Windows solution * provided a VB script that accessed a registry variable ‡,
but my registry value remains the same whether or not I'm docked. 

The Linux solutions required either a file I don't have (/var/run/stab) or a tool
that I don't have and couldn't find in a Cygwin search (acpid or lsusb).

* https://www.autoitscript.com/forum/topic/147332-how-do-you-detect-a-docking-station/
‡ /proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/IDConfigDB/CurrentDockInfo/DockingState

lsusb is part the usbutils package, which is currently in Ports.

If you cat the path to the registry key it doesn't show anything but
if you hexdump it there is a '1' (in my case, 2 out of 2 systems)
stored as a DWORD I suppose. I think that value is wrong for at least
one of those (a docked laptop or a VM in a PC). I got the impression
the feature is not 100% solid.

Great! I now have a workable script: lsusb | grep -qi keyboard

I found it frustrating figuring out cygports until I found
http://www.cygwinports.org/, which clearly told me what to do. 
I wasn't able to find any reference to cygwinports on the cygwin site.

Thank you, Yaakov. ☺
