git - Putting a submodule on the master branch if the checked out HEAD is the tip of master -


is possible checkout master branch in each submodule if , if tip of master checked out commit?

it great if in hook don't have manually.

the reason need can push changed submodules content origin , other remotes afterwards.

generally speaking can use git-submodule foreach stuff iteratively each submodule. run foreach, , compare head master

$(git rev-parse --abbrev-ref head) == $(git rev-parse --abbrev-ref master)

however, may interested know can tell submodules not detach heads when updating defining update property in .gitmodules. find submodule relevant submodule in .gitmodules , add update = rebase or update = merge under it. mean when when submodule update, git go submodule , instead of checking out commit directly (which detaches head), perform either pull or rebase.

documentation bit shotty, take @ submodule.$name.update option, --merge , --rebase update flags, , --branch flag.
