#!/bin/bash

$adb shell am broadcast -a com.android.systemui.demo --es command enter

$adb shell screencap -p /sdcard/screen.png
$adb pull /sdcard/screen.png $folder/$now.png


$adb shell am broadcast -a com.android.systemui.demo --es command exit%                                                                                       

Just replace those 2 vars:
adb is the adb location on your computer
folder is where you want the screenshots to be saved on your computer

I would had a test on the known adb command from the current PATH
