git: Why doesn't git diff show any differences?

Question

If I run \'git status\' on my repo it gives:

# On branch master
# Changes to be committed:
#   (use \"git reset HEAD ...\" to unstage)
#
#   modified         


        

Answer 1

For Staging Area vs Repository comparison use

$git diff --staged

For Working vs Repository comparison use

$ git diff 

but if a file is changed and added to staging area ($ git add fileName) and we try to see the difference with ( $ git diff). It will not return any difference since the file is in staging area and it will not be compared with the repository.
