Merge part of a branch into master with git

Question

I'll explain my scenario:

1. I have two git branches say master, branch1

2. My master branch has following files and commits associated with it - it's like after each file i created i did git commit:

   master-file1.html has masterfile1-commit-message
   master-file2.html - masterfile2-commit-message
   master-file3.html - masterfile3-commit-message
   

3. My branch1 branch has following files and commits associated with it:

   branch1-file1.html has branch1file1-commit-message
   branch1-file2.html - branch1file2-commit-message
   branch1-file3.html - branch1file3-commit-message
   branch1-file4.html - branch1file4-commit-message
   branch1-file5.html - branch1file5-commit-message
   

So i don't want to merge branch1 completely to master branch, i just want partial merge. So at the final i want is something like this:

1. My master branch should be like this:

   master-file1.html has masterfile1-commit-message
   master-file2.html - masterfile2-commit-message
   master-file3.html - masterfile3-commit-message
   branch1-file1.html has branch1file1-commit-message
   branch1-file2.html - branch1file2-commit-message
   

2. My branch1 branch should be unchanged:

   branch1-file1.html has branch1file1-commit-message
   branch1-file2.html - branch1file2-commit-message
   branch1-file3.html - branch1file3-commit-message
   branch1-file4.html - branch1file4-commit-message
   branch1-file5.html - branch1file5-commit-message
   

Can i achieve this in git? If so then how?

Answer 1

First, find the SHA1 hash for the commit with branch1-file2.html. You can do this with the following commands:

git checkout branch1
git log --oneline

Look for the hex string at the beginning of each line. Now once you have the hash, just merge master to it:

git checkout master
git merge <SHA1 hash>
