=========== |

|
NAME |
|
---- |
|
git-diff - Show changes between commits, commit and working tree, etc |
|
|
|
|
|
SYNOPSIS |
|
-------- |
|
'git-diff' [ --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>...]:: |
|
|
|
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]. |
|
|
|
'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. |
|
|
|
'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 |
|
use HEAD to compare it with the latest commit, or a |
|
branch name to compare with the tip of a different |
|
branch. |
|
|
|
'git-diff' [--options] <commit> <commit> [--] [<path>...]:: |
|
|
|
This form is to view the changes between two <commit>, |
|
for example, tips of two branches. |
|
|
|
Just in case if you are doing something exotic, it should be |
|
noted that all of the <commit> in the above description can be |
|
any <tree-ish>. |
|
|
|
|
|
OPTIONS |
|
------- |
|
include::diff-options.txt[] |
|
|
|
<path>...:: |
|
The <paths> 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> |
|
------------ |
|
+ |
|
<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" |
|
|
|
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 behavior, 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. |
