Is there a way to update folder or file alone in Git? I had cloned from central repository and wish to update only specific folder/files.
回答1:
you can use git fetch to update the objects in your local clone, and then you can git checkout those particular files.
For example - if your remote is called origin and you only want to update main.c from the master branch you can do this:
git checkout origin/master main.c
This will update the file in your working directory and add it to the index ready to be committed on your local branch.
回答2:
No, you can only fetch/pull commits, which will affect the entire repository.
