'How do I update a git submodule without checking it out
I am using a git submodule in a very usual way. The way how people typically update a submodule is by checking it out, pulling something in the submodule and then commiting outside.
Now, I typically don't develop those modules in the same place. For me it's more comfortable to develop those two modules in different places. How do I just tell my git project that one submodule has changed and is now at commit XYZ?
I think there's a chance that there's a setting somewhere in .git that I could modify.

A self-explanatory example :
git update-index --cacheinfo 160000,03d7dff560ac8ed64f16e763204b04ce91ca5faf,submodules/submodule
Explanation:
- 160000 : mode; here it indicates a directory (see doc and search for 160000)
- 03d7dff560ac8ed64f16e763204b04ce91ca5faf: the commit id (or commit hash or sha-1) in the submodule repository to which you want to point from your current repository
- submodules/submodule: path the the submodule location in the git repository, no trailing slash (gives error), no .git
Remember, this only updates the index, you are still expected to commit the change!
