git diff HEAD^ HEAD <filename> displays nothing

I am trying to show the diff between the last commit and the one before:

git diff HEAD^ HEAD <filename>

but that displays nothing. I know in fact that there is difference between the two commits.

What am I doing wrong and how should I correct it?

P.S.: I feel that this has been discussed many times before but somehow can't find any useful reference.

The changes you made in HEAD in a particular file are obviously not there in HEAD^ otherwise it wouldn't be part of the commit at all.

The command to see those changes is: git show HEAD -- <filename>

It would display nothing if that particular file had no changes between HEAD^ and HEAD.

Note that with git1.8.5+, you can do a:

git diff @^ -- afile

(@ means HEAD)

git log -p -- aFile would give all the SHA1 were a change for that file occurred.
(-p for displaying the diff)

To see the last modification on a file (without having to deal with HEAD or other SHA1):

git log -1 -p -- aFile
