Set branch for all Git Submodules

Is there a command to set the same branch name for all existing Git Submodules

git submodule add -b develop *

Basically I need a way to recursively set the branch for each module in the .gitmodules file.

Looking for a way to recursive set the branch in the .gitmodules file

With Git 2.22 (Q2 2019, four years later), you will be able to use git submodule set-branch -b <abranch>, because git submodule learns set-branch subcommand that allows the submodule.*.branch settings to be modified.

See commit b57e811, commit c89c494 (08 Feb 2019), and commit 7a4bb55 (07 Feb 2019) by Denton Liu (Denton-L).

submodule: teach set-branch subcommand

This teaches git-submodule the set-branch subcommand which allows the branch of a submodule to be set through a porcelain command without having to manually manipulate the .gitmodules file.

In your case, for all submodules, using git submodule foreach:

git submodule foreach 'git submodule set-branch --branch aBranch -- ${sm_path}'
git submodule foreach 'git submodule set-branch --default -- ${sm_path}'

(the last line set the master branch, which is the default)


Before Git 2.22, you would use the command I mentioned in "How can I specify a branch/tag when adding a Git submodule?"

 git submodule foreach 'git config -f .gitmodules submodule.${sm_path}.branch <branch>'

Note: Git 2.24 (Q4 2019) makes clear the --default and --branch options are mutually exclusive.

See commit 40e747e (16 Sep 2019) by Denton Liu (Denton-L).

See git submodule foreach.

Evaluates an arbitrary shell command in each checked out submodule.

git submodule foreach git checkout -b develop
