Execute commands inside subshell from script

Question

In order to retrieve my Android app's database from device, I execute this commands:

prompt1> adb shell
prompt2> run-as my.app.package
prompt3> chmod -R 777 databases
prompt3> exit
prompt2> cat /data/data/my.app.package/databases/database.db > /sdcard/database.db
prompt2> exit
prompt1> adb pull /sdcard/database.db

I want automate this process so I have created a script with those commands. Problem is that when I execute it, adb shell is opened and the next commands are not executed.

Note that run-as my.app.package opens another third shell.

EDIT

When I execute the script:

prompt1> get_database.cmd
prompt2> _

It opens prompt2, but it stops.

How can I do it?

Your examples are somewhat confusing. Are you searching for a solution in a UNIX-like shell (say sh, csh, etc.) or for Windows' CMD? — Christian.K

Then I would suggest, you rework your question (examples). The first one sports a whole slew of UNIXish commands (cat, chmod, etc.) can lead to the impression that you're actually looking for sh. — Christian.K

You can try passing the commands to the shell with quotes:

adb shell "
adb run-as my.app.package 'chmod -R 777 databases; exit'
cat /data/data/my.app.package/databases/database.db > /sdcard/database.db
exit
"
adb pull /sdcard/database.db

Can you add some details? The single quote '...' can be replaced by an external file adb run-as my.app.package < script.adb with chmod -R 777 databases; exit inside script.adb

Finally, I have solved it this way:

@echo off
IF "%1" == "" goto USAGE
IF "%2" == "" goto USAGE

adb shell "run-as %1 chmod -R 777 /data/data/%1/databases; cat /data/data/%1/databases/%2 > /sdcard/%2"
adb pull /sdcard/%2
goto END

:USAGE
@echo Usage: %0  ^<package^> ^<file_name^>

:END
