您可以检查remote分支的reflog，以查看提拉之前的提交：

$ git reflog origin/master              # <- 'origin/master', not 'master'
3ab2281 refs/remotes/origin/master@{0}: pull: fast-forward  # <-last pull
3cdd5d1 refs/remotes/origin/master@{1}: fetch: fast-forward # <-previous pull
cda1bbd refs/remotes/origin/master@{2}: fetch: fast-forward
5b18e70 refs/remotes/origin/master@{3}: fetch: fast-forward
...

然后，您可以查看最后列出的两个提交之间的差异：

$ git diff 3cdd5d1 3ab2281         # usual diff in terminal

# or

$ git difftool -d 3cdd5d1 3ab2281  # graphical diff viewer

要简单地查看已修改文件的列表，以及A dded、M odified或D eleted的小标记：

$ git diff --name-status 3cdd5d1 3ab2281
M       .travis.yml
M       Documentation/RelNotes/2.10.2.txt
M       Documentation/RelNotes/2.11.0.txt
M       Documentation/config.txt
M       Documentation/diff-config.txt
...

[edit]origin/master@{xx}实际上是指向“reflog中第xx个条目”的有效方法，因此您还可以运行：

git diff origin/master@{1} origin/master
git difftool -d origin/master@{1} origin/master
git diff --name-status origin/master@{1} origin/master
...
