section in linkgit:gitrevisions[7].
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 linkgit:gitrevisions[7].

`git diff [<options>] <blob> <blob>`::

	This form is to view the differences between the raw
	contents of two blob objects.

OPTIONS
-------
:git-diff: 1
include::diff-options.adoc[]

`-1`::
`--base`::
`-2`::
`--ours`::
`-3`::
`--theirs`::
	Compare the working tree with
+
--
 * the "base" version (stage #1) when using `-1` or `--base`,
 * "our branch" (stage #2) when using `-2` or `--ours`, or
 * "their branch" (stage #3) when using `-3` or `--theirs`.
--
+
The index contains these stages only for unmerged entries i.e.
while resolving conflicts.  See linkgit:git-read-tree[1]
section "3-Way Merge" for detailed information.

`-0`::
	Omit diff output for unmerged entries and just show
	"Unmerged".  Can be used only when comparing the working tree
	with the index.

`<path>...`::
	The _<path>_ parameters, when given, are used to limit
	the diff to the named paths (you can give directory
	names and get diff for all files under them).

EXAMPLES
--------

Various ways to check your working tree::
+
------------
$ git diff            <1>
$ git diff --cached   <2>
$ git diff HEAD       <3>
$ git diff AUTO_MERGE <4>
------------
+
<1> Changes in the working tree not yet staged for the next commit.
<2> Changes between the index and your last commit; what you
    would be committing if you run `git commit` without `-a` option.
<3> Changes in the working tree since your last commit; what you
    would be committing if you run `git commit -a`
<4> Changes in the working tree you've made to resolve textual
    conflicts so far.

Comparing with arbitrary commits::
+
------------
$ git diff test            <1>
$ git diff HEAD -- ./test  <2>
$ git diff HEAD^ HEAD      <3>
------------
+
<1> Instead of using the tip of the current branch, compare with the
    tip of "test" branch.
<2> Instead of comparing with the tip of "test" branch, compare with
    the tip of the current branch, but limit the comparison to the
    file "test".
<3> Compare the version before the last commit and the last commit.

Comparing branches::
+
------------
$ git diff topic master    <1>
$ git diff topic..master   <2>
$ git diff topic...master  <3>
------------
+
<1> Changes between the tips of the topic and the master branches.
<2> Same as above.
<3> Changes that occurred on the master branch since when the topic
    branch was started off it.

Limiting the diff output::
+
------------
$ git diff --diff-filter=MRC            <1>
$ git diff --name-status                <2>
$ git diff arch/i386 include/asm-i386   <3>
------------
+
<1> Show only modification, rename, and copy, but not addition
    or deletion.
<2> Show only names and the nature of change, but not actual
    diff output.
<3> Limit diff output to named subtrees.

Munging the diff output::
+
------------
$ git diff --find-copies-harder -B -C  <1>
$ git diff -R                          <2>
------------
+
<1> Spend extra cycles to find renames, copies and complete
    rewrites (very expensive).
<2> Output diff in reverse.
