问题
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.
回答1:
To see the diff for a particular COMMIT hash:
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.
回答2:
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?".

You can also try this easy way:
git show <COMMIT>
回答4:
git show shows the changes made in the most recent commit.
Equivalent to git show HEAD.
git show HEAD~1 takes you back 1 commit.
回答5:
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
回答6:
git show <commit_sha>
This will show you just what's in that commit. I think you can do a range it by just putting a space between two commit shas.
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.
回答7:
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.
回答8:
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.
回答9:
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>
回答10:
Another possibility:
git log -p COMMIT -1
回答11:
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.
回答12:
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
回答13:
I like the below command to compare a specific commit and its last commit:
git diff <commit-hash>^-
Example:
git diff cd1b3f485^-

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

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
回答16:
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.
回答17:
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
commit 7f65b9a9d3820525766fcba285b3c678e889fe3b

CSS changed to maintain the aspect ratio of the channel logos and to fit them properly.
commit c3a61f17e14e2b80cf64b172a45f1b4826ee291f

The ratio of the height to width of the channel images are maintained.
After this
git difftool 7f65b9a9d3820525766fcba285b3c678e889fe3b c3a61f17e14e2b80cf64b172a45f1b4826ee291f

In case of checking the source change in a graphical view,
$gitk (Mention your commit id here)
for example:
$gitk HEAD~1
