Detail change after Git pull

Question

After a Git pull, its output gives a summary on the change amount.

How can I see each or some of the files detailed changes?

Okay, here is my question to Jef

Answer 1

1. How do I know if I was pulling to master? All I did is "git pull".

The command itself works like this:

git pull [options] [ […]]

and per default refers to the current branch. You can check your branches by using

git branch -a

This will list your local and remote branches like for e.g so (Added a --- as divider between local and remote to make it more clear)

*master
foo
bar
baz
---
origin/HEAD -> origin/master
origin/deploy
origin/foo
origin/master
origin/bar
remote2/foo
remote2/baz

When you then take a look at one remote repo, you will see what you are referring to:

git remote show origin

will list like the following:

* remote origin
  Fetch URL: ssh://git@git.example.com:12345/username/somerepo.git
  Push  URL: ssh://git@git.example.com:12345/username/somerepo.git
  HEAD branch: master
  Remote branches:
    foo    tracked
    master tracked
  Local refs configured for 'git push':
    foo    pushes to foo    (up to date)
    master pushes to master (fast-forwardable)

So it's quite easy to be sure where to pull from and push to.

3. how to see the detail change in a specific file?

4. how to see the change in summary output by last git pull again?

The easiest and most elegant way (imo) is:

git diff --stat master@{1}..master --dirstat=cumulative,files

This will give you two blocks of information about the changes in between your last pull an the current state of work. Example output (I added a --- as divider between --stat and --dirstat output to make it more clear):
