DESCRIPTION

|
-----------
|
2010-11-04 21:17:29 +00:00
|
|
|
Show changes between the working tree and the index or a tree, changes
|
2020-06-12 16:20:00 +00:00
|
|
|
between the index and a tree, changes between two trees, changes resulting
|
|
|
|
from a merge, changes between two blob objects, or changes between two
|
|
|
|
files on disk.

|
|
|
This form is to view the changes you made relative to
|
|
|
|
the index (staging area for the next commit). In other
|
2013-01-21 19:17:53 +00:00
|
|
|
words, the differences are what you _could_ tell Git to
|
2006-12-14 08:03:18 +00:00
|
|
|
further add to the index but you still haven't. You can
|
2007-12-29 06:20:38 +00:00
|
|
|
stage these changes by using linkgit:git-add[1].

|
2013-08-28 22:17:18 +00:00
|
|
|
|
|
|
|
This form is to compare the given two paths on the
|
|
|
|
filesystem. You can omit the `--no-index` option when
|
|
|
|
running the command in a working tree controlled by Git and
|
|
|
|
at least one of the paths points outside the working tree,
|
|
|
|
or when running the command outside a working tree
|
2019-10-29 16:54:32 +00:00
|
|
|
controlled by Git. This form implies `--exit-code`.

'git diff' [<options>] --cached [<commit>] [--] [<path>...]::
|
2006-12-14 08:03:18 +00:00
|
|
|
|
|
|
|
This form is to view the changes you staged for the next
|
2006-12-20 22:41:54 +00:00
|
|
|
commit relative to the named <commit>. Typically you
|
2006-12-14 08:03:18 +00:00
|
|
|
would want comparison with the latest commit, so if you
|
|
|
|
do not give <commit>, it defaults to HEAD.
|
2014-02-05 22:19:43 +00:00
|
|
|
If HEAD does not exist (e.g. unborn branches) and
|
2011-02-03 06:23:34 +00:00
|
|
|
<commit> is not given, it shows all staged changes.
|
2008-10-29 16:15:36 +00:00
|
|
|
--staged is a synonym of --cached.

'git diff' [<options>] <commit> [--] [<path>...]::
|
2006-12-14 08:03:18 +00:00
|
|
|
|
|
|
|
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>...]::
|
2006-12-14 08:03:18 +00:00
|
|
|
|
2007-08-28 05:05:19 +00:00
|
|
|
This is to view the changes between two arbitrary
|
|
|
|
<commit>.
|
|
|
|
|
2020-07-13 19:10:08 +00:00
|
|
|
'git diff' [<options>] <commit> <commit>... <commit> [--] [<path>...]::
|
2020-06-12 16:20:00 +00:00
|
|
|
|
|
|
|
This form is to view the results of a merge commit. The first
|
|
|
|
listed <commit> must be the merge itself; the remaining two or
|
|
|
|
more commits should be its parents. A convenient way to produce
|
|
|
|
the desired set of revisions is to use the {caret}@ suffix.
|
|
|
|
For instance, if `master` names a merge commit, `git diff master
|
|
|
|
master^@` gives the same combined diff as `git show master`.
|
|
|
|
|
2020-07-13 19:10:09 +00:00
|
|
|
'git diff' [<options>] <commit>..<commit> [--] [<path>...]::
|
|
|
|
|
|
|
|
This is synonymous to the earlier form (without the "..") for
|
|
|
|
viewing the changes between two arbitrary <commit>. If <commit> on
|
|
|
|
one side is omitted, it will have the same effect as
|
|
|
|
using HEAD instead.
|
|
|
|
|
2018-05-24 20:11:39 +00:00
|
|
|
'git diff' [<options>] <commit>\...<commit> [--] [<path>...]::
|
2007-08-28 05:05:19 +00:00
|
|
|
|
|
|
|
This form is to view the changes on the branch containing
|
|
|
|
and up to the second <commit>, starting at a common ancestor
|
2008-06-30 06:09:04 +00:00
|
|
|
of both <commit>. "git diff A\...B" is equivalent to
|
2018-10-10 22:26:54 +00:00
|
|
|
"git diff $(git merge-base A B) B". You can omit any one
|
2007-08-28 05:05:19 +00:00
|
|
|
of <commit>, which has the same effect as using HEAD instead.
|
2006-12-14 08:03:18 +00:00
|
|
|
|
2018-10-10 22:26:54 +00:00
|
|
|
Just in case you are doing something exotic, it should be
|
2007-08-29 04:47:08 +00:00
|
|
|
noted that all of the <commit> in the above description, except
|
2010-10-11 16:04:08 +00:00
|
|
|
in the last two forms that use ".." notations, can be any
|
2012-12-18 19:35:28 +00:00
|
|
|
<tree>.
|
2005-12-05 08:22:01 +00:00
|
|
|
|
2007-01-18 02:08:09 +00:00
|
|
|
For a more complete list of ways to spell <commit>, see
|

|
"SPECIFYING REVISIONS" section in linkgit:gitrevisions[7].
|
2007-08-28 05:05:19 +00:00
|
|
|
However, "diff" is about comparing two _endpoints_, not ranges,
|
|
|
|
and the range notations ("<commit>..<commit>" and
|
2007-08-29 04:47:08 +00:00
|
|
|
"<commit>\...<commit>") do not mean a range as defined in the
|
2010-10-11 16:03:32 +00:00
|
|
|
"SPECIFYING RANGES" section in linkgit:gitrevisions[7].

|
2013-06-18 14:58:50 +00:00

|
|

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

Compare the working tree with the "base" version (stage #1),
|
|
|
|
"our branch" (stage #2) or "their branch" (stage #3). 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.

Omit diff output for unmerged entries and just show

|

|
with the index.

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).

------------

|
2007-08-01 15:43:06 +00:00
|
|
|
<1> Changes in the working tree not yet staged for the next commit.
|
|
|
|
<2> Changes between the index and your last commit; what you
|
2019-01-22 20:16:35 +00:00
|
|
|
would be committing if you run "git commit" without "-a" option.
|
2007-08-01 15:43:06 +00:00
|
|
|
<3> Changes in the working tree since your last commit; what you
|
2019-01-22 20:16:35 +00:00
|
|
|
would be committing if you run "git commit -a"

|
2007-08-01 15:43:06 +00:00
|
|
|
<1> Instead of using the tip of the current branch, compare with the
|
2019-01-22 20:16:35 +00:00
|
|
|
tip of "test" branch.
|
2007-08-01 15:43:06 +00:00
|
|
|
<2> Instead of comparing with the tip of "test" branch, compare with
|
2019-01-22 20:16:35 +00:00
|
|
|
the tip of the current branch, but limit the comparison to the
|
|
|
|
file "test".
|
2007-08-01 15:43:06 +00:00
|
|

<3> Compare the version before the last commit and the last commit.

<1> Changes between the tips of the topic and the master branches.
|

|
|
<2> Same as above.
|
2007-10-09 21:00:03 +00:00
|
|
|
<3> Changes that occurred on the master branch since when the topic
|
2019-01-22 20:16:35 +00:00

branch was started off it.

|
2014-03-31 22:11:44 +00:00
|
|
|
<1> Show only modification, rename, and copy, but not addition
|
2019-01-22 20:16:35 +00:00
|
|
|
or deletion.
|
2007-08-01 15:43:06 +00:00

|
<2> Show only names and the nature of change, but not actual

2019-01-22 20:16:35 +00:00
|
|
|
diff output.
|
2007-08-01 15:43:06 +00:00

|
2007-08-01 15:43:06 +00:00

|
<1> Spend extra cycles to find renames, copies and complete

2019-01-22 20:16:35 +00:00
|
|

rewrites (very expensive).
