When I do git diff COMMIT
I see the changes between that commit and HEAD (as far as I know), but I would like to see the changes that were made by that single commit.
I haven't found any obvious options on diff
/ log
that will give me that output.
To see the diff for a particular COMMIT
hash, where COMMIT
is the hash of the commit:
git diff COMMIT~ COMMIT
will show you the difference between that COMMIT
's ancestor and the COMMIT
. See the man pages for git diff for details about the command and gitrevisions about the ~
notation and its friends.
Alternatively, git show COMMIT
will do something very similar. (The commit's data, including its diff - but not for merge commits.) See the git show manpage .
(also git diff COMMIT
will show you the difference between that COMMIT
and the head.)
As mentioned in " Shorthand for diff of git commit with its parent? ", you can also use git diff
with:
git diff COMMIT^!
or
git diff-tree -p COMMIT
With git show, you would need (in order to focus on diff alone) to do:
git show --color --pretty=format:%b COMMIT
The COMMIT
parameter is a commit-ish :
A commit object or an object that can be recursively dereferenced to a commit object. The following are all commit-ishes: a commit object, a tag object that points to a commit object, a tag object that points to a tag object that points to a commit object, etc.
See gitrevision "SPECIFYING REVISIONS" to reference a commit-ish.
See also " What does tree-ish mean in Git? ".
你也可以试试这个简单的方法:
git show <COMMIT>
git show
shows the changes made in the most recent commit. It is equivalent to git show HEAD
.
git show HEAD~1
takes you back one commit.
I usually do:
git diff HEAD~1
To show the changes regarding the last commit. If you have more commits just increase the number 1 to how many commits diff you want to see.
Use:
git show <commit_sha>
This will show you just what's in that commit. You can do a range by just putting a space between the two commit SHA-1 hashes.
git show <beginning_sha> <ending_sha>
which is pretty helpful if you're rebasing often because your feature logs will all be in a row.
If you happen to want to look at the last 3 commits you can use the HEAD syntax
git show HEAD~3 HEAD
First get the commit ID using,
git log #to list all
Or
git log -p -1 #last one commit id
Copy commit id.
Now we use two methods to list changes from a specific commit,
Method 1:
git diff commit_id^! #commit id something like this 1c6a6000asad012
Method 2:
git show commit_id
For example: git show 1c6a600a
From the man page for git-diff(1) :
git diff [options] [<commit>] [--] [<path>…]
git diff [options] --cached [<commit>] [--] [<path>…]
git diff [options] <commit> <commit> [--] [<path>…]
git diff [options] <blob> <blob>
git diff [options] [--no-index] [--] <path> <path>
Use the 3rd one in the middle:
git diff [options] <parent-commit> <commit>
Also from the same man page, at the bottom, in the Examples section :
$ git diff HEAD^ HEAD <3>
Compare the version before the last commit and the last commit.
Admittedly it's worded a little confusingly, it would be less confusing as
Compare the most recent commit with the commit before it.
The following seems to do the job; I use it to show what has been brought in by a merge.
git whatchanged -m -n 1 -p <SHA-1 hash of merge commit>
另一种可能:
git log -p COMMIT -1
I like the below command to compare a specific commit and its last commit:
git diff <commit-hash>^-
Example:
git diff cd1b3f485^-
You could use git diff HEAD HEAD^1
to see the diff with the parent commit.
If you only want to see the list of files, add the --stat
option.
git difftool COMMIT^ <commit hash>
is also possible if you have configured your difftool.
See here how to configure difftool . Or the manual page here .
Additionally, you can use git diff-tree --no-commit-id --name-only -r <commit hash>
to see which files been changed/committed in a give commit hash.
To see author and time by commit, use git show COMMIT
. Which will result in something like this:
commit 13414df70354678b1b9304ebe4b6d204810f867e
Merge: a2a2894 3a1ba8f
Author: You <you@you.com>
Date: Fri Jul 24 17:46:42 2015 -0700
Merge remote-tracking branch 'origin/your-feature'
If you want to see which files had been changed, run the following with the values from the Merge line above, git diff --stat a2a2894 3a1ba8f
.
If you want to see the actual diff, run git --stat a2a2894 3a1ba8f
.
如果您只想查看最新提交中的更改,只需git show
即可。
For checking complete changes:
git diff <commit_Id_1> <commit_Id_2>
For checking only the changed/added/deleted files:
git diff <commit_Id_1> <commit_Id_2> --name-only
NOTE : For checking diff without commit in between, you don't need to put the commit ids.
以下代码将显示当前提交
git show HEAD
This command will get you the Git parent commit-hash:
git log -n 2 <commit-hash>
After that git diff-tool <commit-hash> <parent-commit-hash>
Example:
bonnie@bonnie ~/ $ git log -n 2 7f65b9a9d3820525766fcba285b3c678e889fe3

CSS changed to maintain the aspect ratio of the channel logos and to fit them properly.

The ratio of the height to width of the channel images are maintained.
After this
git difftool 7f65b9a9d3820525766fcba285b3c678e889fe3b c3a61f17e14e2b80cf64b172a45f1b4826ee291f
I'm running Git version 2.6.1.windows.1 on Windows 10, so I needed a slight modification to Nevik's answer (tilde instead of caret):
git diff COMMIT~ COMMIT
Another option is to quote the caret:
git diff "COMMIT^" COMMIT
还可以查看特定文件的两次提交之间的更改。
git diff <commit_Id_1> <commit_Id_2> some_dir/file.txt
A few answers miss a special case. How to view changes made by the Root Commit as it does not have a parent/ancestor.
Both
git diff <root_commit>^..<root_commit>

git diff <root_commit>~..<root_commit>

4 files changed, 45 insertions(+)
# 3. Pick a file to check the differences
git show d58e5da myfolder12/file.py
Or, alternatively, check all file differences within a single commit from the list:
git show d58e5da
In case of checking the source change in a graphical view , use:
gitk (your commit id goes here)
For example:
gitk HEAD~1
For me this works just fine
git show COMMIT --compact-summary
Which shows the next information
Output a condensed summary of extended header information such as file creations or deletions ("new" or "gone", optionally "+l" if it's a symlink) and mode changes ("+x" or "-x" for adding or removing executable bit respectively) in diffstat. The information is put between the filename part and the graph part. Implies --stat.
