DESCRIPTION
-----------
between the index and a tree, changes between two trees, changes between
two blob objects, or changes between two files on disk.
-'git diff' [--options] [--] [<path>...]::
+'git diff' [options] [--] [<path>...]::
This form is to view the changes you made relative to
the index (staging area for the next commit). In other
further add to the index but you still haven't. You can
stage these changes by using linkgit:git-add[1].
-'git diff' --no-index [--options] [--] [<path>...]::
+'git diff' [options] --no-index [--] <path> <path>::
This form is to compare the given two paths on the
filesystem. You can omit the `--no-index` option when
or when running the command outside a working tree
controlled by Git.
-'git diff' [--options] --cached [<commit>] [--] [<path>...]::
+'git diff' [options] --cached [<commit>] [--] [<path>...]::
This form is to view the changes you staged for the next
commit relative to the named <commit>. Typically you
<commit> is not given, it shows all staged changes.
--staged is a synonym of --cached.
-'git diff' [--options] <commit> [--] [<path>...]::
+'git diff' [options] <commit> [--] [<path>...]::
This form is to view the changes you have in your
working tree relative to the named <commit>. You can
branch name to compare with the tip of a different
branch.
-'git diff' [--options] <commit> <commit> [--] [<path>...]::
+'git diff' [options] <commit> <commit> [--] [<path>...]::
This is to view the changes between two arbitrary
<commit>.
-'git diff' [--options] <commit>..<commit> [--] [<path>...]::
+'git diff' [options] <commit>..<commit> [--] [<path>...]::
This is synonymous to the previous form. If <commit> on
one side is omitted, it will have the same effect as
using HEAD instead.
-'git diff' [--options] <commit>\...<commit> [--] [<path>...]::
+'git diff' [options] <commit>\...<commit> [--] [<path>...]::
This form is to view the changes on the branch containing
and up to the second <commit>, starting at a common ancestor
