Consider a superproject with a submodule. If the superproject is checked out to a previous commit, how to automatically check out the submodule to the corresponding commit ?

Superproject : A - B

Submodule : X - Y - Z

Superproject HEAD is on B, corresponding index on submodule is on Z. Imagine that in A, submodule index was in X. How can I automatically checkout submodule on X when I check out superproject in A ?

I can do it manually thanks to this question but it is not efficient for superproject with many submodules.

[Edit] By checkout, I mean using git checkout commitSHA1. According to the doc,

Prepare to work on top of , by detaching HEAD at it (see "DETACHED HEAD" section), and updating the index and the files in the working tree.

I want to recompile code as it was in superproject commit A (possibly tagged) without knowing explicitly corresponding submodules indexes.

I believe the command you're looking for is:

git submodule update

That should get all your submodules to the right version (when run after your git checkout)
