Use a command like:
git diff file_2.rb
See the git diff documentation for full information on the kinds of things you can get differences for.
Normally, git diff by itself shows all the changes in the whole repository (not just the current directory).

Another method (mentioned in this SO answer) will keep the history in the terminal and give you a very deep track record of the file itself:
git log --follow -p -- file
This will show the entire history of the file (including history beyond renames and with diffs for each change).
In other words, if the file named bar was once named foo, then git log -p bar (without the --follow option) will only show the file's history up to the point where it was renamed -- it won't show the file's history when it was known as foo. Using git log --follow -p bar will show the file's entire history, including any changes to the file when it was known as foo.

How to view changes in Git - Graphite
This guide will explore the different methods to view changes in Git, using commands like `git diff`, `git status`, and others.
What command can view who changed specific line of a file?
You probably want: git blame $filename This will output the file with each line annotated with the commit hash, date and author at which the line was last changed. This uses the same logic that git diff uses to calculate diffs. (Remember, Git does not directly store changes; it calculates changes on the fly as required.) You can provide extra options to see the file as of a particular commit, or to ignore certain uninteresting changes. More on reddit.com

This is a bit of an older question, but seems like people might be landing here from search results. We have a bit of a bias, but in general, GUI tools are a great way to visualize and see these details without needing to memorize the args for git blame https://git-scm.com/tools/guis

You're looking for
git diff --staged
Depending on your exact situation, there are three useful ways to use git diff:
- Show differences between index and working tree; that is, changes you haven't staged to commit:
git diff [filename]
- Show differences between current commit and index; that is, what you're about to commit (
--stageddoes exactly the same thing, use what you like):
git diff --cached [filename]
- Show differences between current commit and working tree:
git diff HEAD [filename]
git diff works recursively on directories, and if no paths are given, it shows all changes.
