Does anyone know how to invoke a bash process via a dos batch program so
commands after bash execute?

For example.
batch1.bat contains:

REM This is batch1.bat
batch2.bat test
exit


batch2.bat contains:

REM this is batch2.bat
echo %1
bash
echo %1
exit


The result set is:
test

I want it to be:
test
test
