How to checkout a file from one git branch to another?

Hello and welcome back to my blog! Today I wanted to write about something new that I learned I can do with the git checkout command.

Consider this, you have a bunch of files that you are working with in your current developmment branch. Now you need to start a new feature, but you need only a subset of files from your current development branch that needs to be ported to the new one.

Here is how you go about this:

Scenario:
Let's call your git repository as TheNetworkHippoRepo. Say you have a branch called branch-a in this repository where you have a file called file-a. Let's assume there are a bunch of other files too, but file-a is the one of interest to us.

Now you need to develop a new feature, and you create a new branch off of your mainline called branch-b. Here's how you can "checkout" file-a from branch-a to branch-b:

git checkout branch-a -- file-a

And just like that, you have only file-a available in your new branch!

Hope you learned something new!
