git partial merge

Notice that in my case, the target files in branch-tmp are completely applicable for chengdol_master, so I just want to overwrite corresponding files in chengdol_master. If we need to pick some changes and leave others in the file, do an interactive merge, run this from chengdol_master:

1	git checkout --patch brach-tmp <relative path to target file>

First check if you have origin/branch-tmp locally

1

git branch -r | grep branch-tmp

If not, you need to fetch it alone or fetch all origin branches:

1
2

git fetch origin branch-tmp
git fetch origin

Then go to your target branch chengdol_master, use git checkout command to do the job:

1

git checkout origin/branch-tmp <relative path to target file>

then the merged files from branch-tmp are in staging phase, you can directly commit or unstage them in the chengdol_master branch, then push and handle the pull request.
