Any difference between git add . and git add --all?

Question

Is there any difference between:

git add .

and

git add --all

?

Answer 1

The accepted answer is valid for Git 1.x. But for Git versions from 2.0 and above, following is the difference:

git add .

Adds, modifies and removes index entries/files in the current directory and its subdirectories.

While

git add -all

And

git add -A

Adds, modifies and removes all index entries/files to match the entire working tree of the repository.

Refer Git documentation for git add here.
