 SYNOPSIS

-'git-diff-cache' [-p] [-r] [-z] [-m] [-M] [-R] [--cached] <tree-ish>
+'git-diff-cache' [-p] [-r] [-z] [-m] [--cached] [-R] [-B] [-M] [-C] [--find-copies-harder] [-O<orderfile>] [-S<string>] [--pickaxe-all] <tree-ish> [<path>...]
 
 DESCRIPTION
 -----------
-Compares the content and mode of the blobs found via a tree object
-with the content of the current cache and, optionally ignoring the
-stat state of the file on disk.
+Compares the content and mode of the blobs found via a tree
+object with the content of the current cache and, optionally
+ignoring the stat state of the file on disk.  When paths are
+specified, compares only those named paths.  Otherwise all
+entries in the cache are compared.
 
 OPTIONS

 -z::
 	\0 line termination on output
 
+-B::
+	Break complete rewrite changes into pairs of delete and create.
+
 -M::
-	Detect renames; implies -p.
+	Detect renames.
+
+-C::
+	Detect copies as well as renames.
+
+--find-copies-harder::
+	By default, -C option finds copies only if the original
+	file of the copy was modified in the same changeset for
+	performance reasons.  This flag makes the command
+	inspect unmodified files as candidates for the source of
+	copy.  This is a very expensive operation for large
+	projects, so use it with caution.
+
+-S<string>::
+	Look for differences that contains the change in <string>.

+--pickaxe-all::
+	When -S finds a change, show all the changes in that
+	changeset, not just the files that contains the change

+-O<orderfile>::
+	Output the patch in the order specified in the

 -R::
-	Output diff in reverse.
+	Swap two inputs; that is, show differences from cache or

 	do not consider the on-disk file at all
