Diff current file version and previous one remote repository

How do I diff my working file version vs. some previous version in the remote repository?

Say, I pull today, perform 6 - 8 commits to my local copy and then want to see the diff between my latest working version ( of a given file ) and the latest on the remote or any other version.

Suppose path/to/file.txt is some file that's committed to the remote branch origin/master and is also in my workspace, committed to the local branch my-branch.

Difference between the latest version of path/to/file.txt committed the remote branch and the (possibly uncommitted) version in my workspace:

git diff origin/master:path/to/file.txt path/to/file.txt

Difference between the version of path/to/file.txt committed the remote branch three commits ago and the (possibly uncommitted) version in my workspace:

git diff origin/master~3:path/to/file.txt path/to/file.txt

Difference between the latest version of path/to/file.txt committed the remote branch and the latest version committed to my-branch:

git diff origin/master:path/to/file.txt my-branch:path/to/file.txt

git fetch;  #this will attach the remote branch commits to your local tree
git diff FETCH_HEAD    #diff your working dir version of my_file vs the remote tip

same as
git diff remotes/origin/branch

But you must do a git-fetch first or you won't have the remote's commits locally available to diff against

To see the diff between your 'latest working version' (I'll take that as your working copy) use:

git diff <remote>/<branch>

If you think somebody else has pushed to the remote then you need to fetch the changes:

git fetch <remote> <branch>
git diff <remote>/<branch>

If you want to restrict the diff to just a file or to all files in a directory use:

git diff <remote>/<branch> -- /path/to/file
git diff <remote>/<branch> -- /path/to/           #all files in directory

You can use git difftool ... to start a visual diff tool (assuming one exists on your machine).

If you're talking about a remote branch, say, origin/master, you can use ~ and ^ to refer to ancestor commits relative to a branch the same way you can with local branches:

# what change was introduced to origin/master in the last 4 commits?
git diff origin/master origin/master~3

If you want to diff your current working directory against the 5th most recent commit on origin/master, you would omit the first argument:

git diff origin/master~4
