SYNOPSIS
--------
-'git
-diff' [<common diff options>] <commit>{0,2} [--] [<path>...]
+'git
diff' [<common diff options>] <commit>{0,2} [--] [<path>...]
DESCRIPTION
-----------
Show changes between two trees, a tree and the working tree, a
tree and the index file, or the index file and the working tree.
-'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
words, the differences are what you _could_ tell git to
further add to the index but you still haven't. You can
- stage these changes by using gitlink:git-add[1].
+ stage these changes by using linkgit:git-add[1].
+
If exactly two paths are given, and at least one is untracked,
compare the two files / directories. This behavior can be
forced by --no-index.
-'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
would want comparison with the latest commit, so if you
do not give <commit>, it defaults to HEAD.
+ --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
- of both <commit>. "git-diff A\...B" is equivalent to
- "git-diff $(git-merge-base A B) B". You can omit any one
+ of both <commit>. "git diff A\...B" is equivalent to
+ "git diff $(git-merge-base A B) B". You can omit any one
of <commit>, which has the same effect as using HEAD instead.
Just in case if you are doing something exotic, it should be
<tree-ish>.
For a more complete list of ways to spell <commit>, see
-"SPECIFYING REVISIONS" section in gitlink:git-rev-parse[1].
+"SPECIFYING REVISIONS" section in linkgit:git-rev-parse[1].
However, "diff" is about comparing two _endpoints_, not ranges,
and the range notations ("<commit>..<commit>" and
"<commit>\...<commit>") do not mean a range as defined in the
-"SPECIFYING RANGES" section in gitlink:git-rev-parse[1].
+"SPECIFYING RANGES" section in linkgit:git-rev-parse[1].
