How do I show the changes which have been staged?

How do I show the changes which have been staged?

I staged a few changes to be committed; how can I see the diff of all files which are staged for the next commit? I'm aware of git status, but I'd like to see the actual diffs - not just the names of files which are staged.

I saw that the git-diff(1) man page says

git diff [--options] [--] [?]

This form is to view the changes you made relative to the index (staging area for the next commit). In other words, the differences are what you could tell git to further add to the index but you still haven't. You can stage these changes by using git-add(1).

Unfortunately, I can't quite make sense of this. There must be some handy one-liner which I could create an alias for, right?

Answer by Charles Bailey for How do I show the changes which have been staged?

It should just be:

git diff --cached  

--cached means show the changes in the cache/index (i.e. staged changes) against the current HEAD. --staged is a synonym for --cached.

EDIT

Just to clarify the above statement, --staged and --cached does not point to HEAD, just difference with respect to HEAD. If you cherry pick what to commit using git add --patch (or git add -p), --staged will return what is staged.

Answer by Abizern for How do I show the changes which have been staged?

A simple graphic makes this clearer

git diff

Shows the changes between the working directory and the index. This shows what has been changed, but is not staged for a commit.

git diff --cached

Shows the changes between the index and the HEAD(which is the last commit on this branch). This shows what has been added to the index and staged for a commit.

git diff HEAD

Shows all the changes between the working directory and HEAD (which includes changes in the index). This shows all the changes since the last commit, whether or not they have been staged for commit or not.

Answer by Fred Schoen for How do I show the changes which have been staged?

If you have more than one file with staged changes, it may more practical to use git add -i, then select 6: diff, and finally pick the file(s) you are interested in.

If you'd be interested in a visual side-by-side view, the

href="http://diffuse.sourceforge.net/">diffuse visual diff tool can do that. It will even show three panes if some but not all changes are staged. In the case of conflicts, there will even be four panes.

Invoke it with

diffuse -m  

in your Git working copy.

If you ask me, the best visual differ I've seen for a decade. Also, it is not specific to Git: It interoperates with a plethora of other VCS, including SVN, Mercurial, Bazaar, ...

Answer by VonC for How do I show the changes which have been staged?

Note that git status -v also shows the staged changes! (meaning you need to have staged -- git add -- some changes. No staged changes, no diff with git status -v.
It does that since Git 1.2.0, February 2006)

In its long form (default), git status has an undocumented "verbose" option which actually display the diff between HEAD and index.

And it is about to become even more complete: see "Show both staged & working tree in git diff?" (git 2.3.4+, Q2 2015):

git status -v -v  

Answer by Marc Condon for How do I show the changes which have been staged?

If your intentions are to push-target a remote repo branch and your first pass at a commit change log were incomplete, you can correct the commit statement before pushing like this.

Locally

... make some changes ...

git diff # look at unstaged changes    git commit -am"partial description of changes"  

... recall more changes unmentioned in commit ...

git diff origin/master # look at staged but not pushed changes

... amend staged commit statement ...

git commit --amend -m"i missed mentioning these changes ...."    git push  

Answer by nobar for How do I show the changes which have been staged?

git gui and git-cola are graphical utilities that let you view and manipulate the index. Both include simple visual diffs for staged files, and git-cola can also launch a more sophisticated side-by-side visual diff tool.

See my closely related answer at How to remove a file from the index in git?, and also this official catalog of Git - GUI Clients.

Answer by sam for How do I show the changes which have been staged?

Answer by Yash Patadia for How do I show the changes which have been staged?

You can use this command.

git diff --cached --name-only  

The --cached option of git diff means to get staged files, and the --name-only option means to get only names of the files.
