“git add -A”和“git add --update :/”有什么区别？

Question

I was in the past using this Git command for my files:

add --update :/ 

as someone told me this was the best way to pick up all the files that had been added, deleted and updated.

However after reading: Difference between "git add -A" and "git add ."

I think maybe I should be using git add -A

Can someone tell me if there's a difference and what git add --update :/ actually does?

Answer 1

git add --update :/ will update or remove previously tracked files from the entire working tree. It will not add new files.

git add -A will also update, remove previously tracked files, but it will also add new files. As this command doesn't have the explicit pathspec of :/ that your update command does, depending on your version of git, this may be for all files in the entire working tree, or it may be for the current directory and all subfolders and files.
