I this article you will see that how to stage all changes with new files in a git repository and how to stage deleted files in git repository. 

 
The main difference between "git add -A" and "git add ." is the scope of the changes that they stage for a commit.

"git add -A" stages all changes in the entire repository, including new, modified, and deleted files. This command is equivalent to "git add --all", and it will stage all changes regardless of their current status.

On the other hand, "git add ." stages only the changes in the current directory and its subdirectories. This command stages new and modified files, but it does not stage deleted files. To stage deleted files, you will need to use the "git add -u" command.

In summary:

• "git add -A" stages all changes in the entire repository (new, modified, and deleted files)
• "git add ." stages only the changes in the current directory and its subdirectories (new and modified files, but not deleted files).

It is important to note that when using git add . it will only stage the changes that are in the working tree, not the files in the gitignore, where as git add -A will stage them regardless if they are in gitignore or not.

To stage all changes, including new files, in a git repository, you can use the command "git add -A" or "git add --all". This command will stage all changes in the entire repository, regardless of their current status.

git add -A

To stage deleted files in a git repository, you can use the command "git add -u" or "git add --update". This command will stage deleted files, but it will not stage new files.

git add -u

You can also use

git add -A :/ 

This will stage all changes in the entire repository, including new, modified, and deleted files, but ignoring files that are untracked and files under .gitignore.

It's also worth noting that if you want to stage all changes, including new and deleted files, in the current directory and its subdirectories, you can use the command "git add -A ."

git add -A .
