What is the difference between running
git submodule update --remote vs
cd <submodule directoy> git pull Assuming that the submodule was previously set to track some branch:
git submodule add -b master [URL to Git repo] 可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试):

The difference is:
git pullwill only update your submodule branch, but it can be any branch that you could have checked out yourself in that submodule repo.git submodule update --remotewill only update the branch registered in the.gitmodule, and by default, you will end up with a detached HEAD, unless--rebaseor--mergeis specified or the keysubmodule.$name.updateis set torebase,mergeornone.
In both cases, you still have to go back to the parent repo, add and commit the new submodule SHA1 reference.
That is because in both instances, the SHA1 of the submodule changes, which means the gitlink (special entry in the index of the parent repo, named after to root folder of the submodule) must be added and committed.
