 Why is that git diff thinks there are no changes

..even if git status reports them as modified?

$ git status

Answer 1

Ran into the exact same problem.

• Add the new file that you created using git add filename1.c
• Make another change in some other filename2.c that was already a part of the repository tracking system.
• Do a git diff and you will only see the change to filename2.c show up. Changes to filename1.c will not show up.
• However if you do a git status you will see the changes in both filename1.c and filename2.c show up.
• Do a git commit -a -m "Changes to filename1.c and filename2.c blah blah"
• Do a git push

You will see that filename1.c got committed.
