According to git version 1.x
“git add -A” is equivalent to “git add .” and “git add -u“
- git add -A stages All
- git add . stages new and modified, without deleted
- git add -u stages modified and deleted, without new
The important point about git add . is that it looks at the working tree and adds all those paths to the staged changes if they are either changed or are new and not ignored, it does not stage any ‘rm’ actions.
git add -u looks at all the already tracked files and stages the changes to those files if they are different or if they have been removed. It does not add any new files, it only stages changes to already tracked files.
git add -A is a handy shortcut for doing both.
- git add -A is equivalent to git add –all
- git add -u is equivalent to git add –update
According to git version 2.x
- git add -A stages All
- git add . stages All in same path
- git add -u stages modified and deleted, without new
There is no more difference in 2.0. git add . equals to git add -A for the same path, the only difference is if there are new files in other paths of the tree.
With Git 2.0, git add -A is default: git add . equals git add -A .
