Question

How can I see the differences in a designated file between a local branch and a remote branch?

I know this command:

git diff <local branch> <remote-tracking branch>

But it gives the differences in all files between two branches while I only care about changes of one single designated file.

Take a look at git diff --help, which shows you:

git diff [options] <commit> <commit> [--] [<path>...]

So, you’re almost there. Instead of:

git diff <local branch> <remote-tracking branch>

You can use:

git diff <local branch> <remote-tracking branch> path/to/file
