How to add files to another branch?

Question

For some reason I want to abandon my branch_A but I have some files just committed in that branch_A. I want to add them to branch_B. How can I do that?

Answer 1

Switch on the branch B:

git checkout branch_B

Then, checkout the files you want to keep:

git checkout branch_A file1 file2 file3 [...]

At last, commit your changes

git commit -m "Backport changes from branch A for reasons"
