How to detect cpu architecture and deliver correct apk?

There are a variety of CPU architectures that android systems use such as

-v8a

,

-v7a

,

,

and

. Is there a way for

or any other tool to detect the architecture of a connected device? I have many devices connected to a PC running adb and I would like to create a script so that

can deliver the correct package. For example, I have packages

-v8a.apk

,

-v7a.apk

and

.apk

on my desktop that correspond to their respective architectures as well as tens of android devices that are connected to an

server on desktop. How can I iterate the output of

devices

so that the script figures out the architecture of each android device and automatically install the right apk to each device?
