-The diff commands git-diff-cache, git-diff-files, and
+The diff commands git-diff-index, git-diff-files, and
git-diff-tree can be told to manipulate differences they find
in unconventional ways before showing diff(1) output. The
manipulation is collectively called "diffcore transformation".
The git-diff-* family works by first comparing two sets of
files:
- - git-diff-cache compares contents of a "tree" object and the
+ - git-diff-index compares contents of a "tree" object and the
working directory (when '--cached' flag is not used) or a
"tree" object and the index file (when '--cached' flag is
used);
