Sorry, but I do not use it. I will send You a normal email.

I have added two options to git submodule update: --save-progress --resume-update First one You can use, to save the ./.git/SubmoduleUpdateLog.log the progress of updating: git submodule update --recursive --save-progress The second one is used for skipping updated submodules: git submodule update --recursive --resume-update

The downside of it is, that u can use only one --resume-update. If there will be another error, then using it again will start form the last submodule that --save-progres saved.

I have send two files: "git-submodule" - it has my changes "git-submodule - Original" - it not modyfied so that You can see what lines I have added.

Let me know if this change will be in next version of git.

Best regards, Lukasz Palczewski
