git中staged 和 unstaged的区别

总结:

Untracked：不在Git里.
Unstaged：在Git里但没有commit.
Staged：在Git里且已commit

Furthermore, what are staged changes?

Suppose you have edited three files ( a. After that you need to commit all the changes so that the changes to a.

Additionally, what is staged and unstaged files in Sourcetree? The unstaged files are just the files with the last modifications you brought. The staged file are like a snapshot that you take at a T time, Git will store these snapshots under staged files (one snapshot/file at a time).
unstaged文件就是你最后修改过的文件。staged文件类似于您在T时刻拍摄的快照，Git将这些快照存储在staged 文件中(每次一个快照/文件)。

how do you get staged changes?

If you want to see what you’ve staged that will go into your next commit, you can use git diff --staged. This command compares your staged changes to your last commit. The command compares what is in your working directory with what is in your staging area.

The “changes not staged for commit” message shows when you run the “git status” command and have a file that has been changed but has not yet been added to the staging area.
