NAME
|
|
----
|
|
git-diff - Show changes between commits, commit and working tree, etc.
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git-diff' [ --diff-options ] <ent>{0,2} [<path>...]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Show changes between two ents, an ent and the working tree, an
|
|
ent and the index file, or the index file and the working tree.
|
|
The combination of what is compared with what is determined by
|
|
the number of ents given to the command.
|
|
|
|
* When no <ent> is given, the working tree and the index
|
|
file is compared, using `git-diff-files`.
|
|
|
|
* When one <ent> is given, the working tree and the named
|
|
tree is compared, using `git-diff-index`. The option
|
|
`--cached` can be given to compare the index file and
|
|
the named tree.
|
|
|
|
* When two <ent>s are given, these two trees are compared
|
|
using `git-diff-tree`.
|
|
|
|
OPTIONS
|
|
-------
|
|
--diff-options::
|
|
'--diff-options' are passed to the `git-diff-files`,
|
|
`git-diff-index`, and `git-diff-tree` commands. See the
|
|
documentation for these commands for description.
|
|
|
|
<path>...::
|
|
The <path> arguments are also passed to `git-diff-\*`
|
|
commands.
|
|
|
|
|
|
EXAMPLES
|
|
--------
|
|
|
|
Various ways to check your working tree::
|
|
+
|
|
------------
|
|
$ git diff <1>
|
|
$ git diff --cached <2>
|
|
$ git diff HEAD <3>
|
|
|
|
<1> changes in the working tree since your last git-update-index.
|
|
<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"
|
|
------------
|
|
|
|
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.
|
|
------------
|
|
|
|
|
|
Limiting the diff output::
|
|
+
|
|
------------
|
|
$ git diff --diff-filter=MRC <1>
|
|
$ git diff --name-status -r <2>
|
|
$ git diff arch/i386 include/asm-i386 <3>
|
|
|
|
<1> show only modification, rename and copy, but not addition
|
|
nor deletion.
|
|
<2> show only names and the nature of change, but not actual
|
|
diff output. --name-status disables usual patch generation
|
|
which in turn also disables recursive behaviour, so without -r
|
|
you would only see the directory name if there is a change in a
|
|
file in a subdirectory.
|
|
<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.
