Git remove a file from existing branch to another existing branch

Question

I want to remove a file from existing branch and add it in another existing branch. For example I have two branch a and b. I'm in branch a and I want to remove a file a.php from branch a and add to this file in existing branch b.

Answer 1

First add a.php into branch B:

Checkout branch B:

git checkout branchB

Checkout file from branchA

git checkout branchA a.php

Then commit this file

git commit

Then delete a.php from branchA

Checkout branch A:

git checkout branchA

Delete the file

git rm a.php

And commit the deletion

git commit
