I am not sure whether I understand it correctly or not, we could simply provide the shell window by invoking 'sh', right? If we do that then is there need to use xargs? I am not particularly experienced with xargs, I was thinking of something as follows:

#!/bin/sh echo "Submodule a" ( PS1="module/submodule$" sh ) echo "" #In case of ctrl+D to ensure that there is a blank line echo "Submodule a ends"

I do agree that it would be powerful enough to serve all the necessary purpose for traversing git submodules. If my assumption is right in what we want then I will resubmit the patch with required changes.
