Working with GIT is one of the best things that happened to software development. However, sometimes in very rare instances, you may have the need to copy(checkout) a file from one branch to the other.

Here is a quick tip should you ever need to do that, assuming you want to copy the file "composer.lock" from branch A to B

1. Check into branch A and pull in the latest changes

git checkout A && git pull

2. Check into branch B

git checkout B

3. Checkout the file - make sure to use the correct path

git checkout A composer.lock

4. Should you wish to add the file to the current branch, run this:

git add composer.lock

That's it, hope it was useful 🤩🤩🤩
