shell/ batch scripting to direct commands to adb shell

Question

I am trying to write a batch(for win) and a shell script for linux to automate key and touch events on a android UI. At the moment in a windows batch file I am starting a adb shell for each event for eg

    :again

adb shell am start -a android.intent.action.MAIN -n com.q.me.fui.activity/.InitActivity

sleep 15

adb shell sendevent /dev/input/event0 3 0 281
adb shell sendevent /dev/input/event0 3 1 70
adb shell sendevent /dev/input/event0 1 330 1
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 1 330 0
adb shell sendevent /dev/input/event0 0 0 0   
adb shell sendevent /dev/input/event0 1 330 1
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 1 330 0
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 0 0 0
adb shell sendevent /dev/input/event0 0 0 0   

sleep 5

adb shell input keyevent 82
adb shell input keyevent 20
adb shell input keyevent 20
adb shell input keyevent 22
adb shell input keyevent 22
adb shell input keyevent 22
adb shell input keyevent 66

sleep 5

goto again

The above code is infact starting a new adb shell each time. I want to avoid this. I want my batch script to start the adb shell only once and I would like to route the sendevent and other commands to the subshell, ie the adb shell.

Any idea how I can do this in win batch and Lin shell script?

Put all the commands you want to run at once in an external file, one per line, then run:

adb shell < commands.txt
