Question

I have read the docs as well but could not get one thing.

Suppose I added new files to the repo.

Then which command do I need to execute first:

git add -A 

or

git commit - m "test"

Answer 1

You should first execute git add . to stage the new/modified files and then git commit -m "your message" to write those changes to the repository.

You can see in here the different file statuses in git, and I strongly recommend you to read the whole book.

EDIT:

To make it clear, what you are doing with git add . is basically telling git ‘Hey, I have new/modified/untracked files that I’d like to include in my next commit’, so that the next time you execute git commit those files changes are written to the repository.
