You were comparing the working tree with the index (staging area).

Show 17 quoted lines

git doesn't know about random.xml here, which you can change like so:

git add -N random.xml

Then git diff -M --name-status HEAD will show the rename.

Alternatively, you could have used "git mv randomfile.xml random.xml" which would have staged that move in the index already. (More exactly: the content changes, not the move as such)
