How to see the changes in a Git commit

Question

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

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.

The ratio of the height to width of the channel images are maintained.

After this

git difftool 7f65b9a9d3820525766fcba285b3c678e889fe3b c3a61f17e14e2b80cf64b172a45f1b4826ee291f

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  lt SHA-1 hash of merge commit gt

git show  lt commit sha gt    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  lt beginning sha gt   lt ending sha gt    which is pretty helpful if you re rebasing often because your feature logs will all be in a row

Another possibility   git log -p COMMIT -1

For checking complete changes     git diff  lt commit Id 1 gt   lt commit Id 2 gt    For checking only the changed added deleted files     git diff  lt commit Id 1 gt   lt commit Id 2 gt  --name-only   NOTE  For checking diff without commit in between  you don t need to put the commit ids

From the man page for git-diff 1    git diff  options    lt commit gt    --    lt path gt      git diff  options  --cached   lt commit gt    --    lt path gt      git diff  options   lt commit gt   lt commit gt   --    lt path gt      git diff  options   lt blob gt   lt blob gt  git diff  options   --no-index   --   lt path gt   lt path gt    Use the 3rd one in the middle   git diff  options   lt parent-commit gt   lt commit gt    Also from the same man page  at the bottom  in the Examples section     git diff HEAD  HEAD       lt 3 gt       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

I like the below command to compare a specific commit and its last commit   git diff  lt commit-hash gt  -   Example   git diff cd1b3f485 -

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

git difftool COMMIT   lt commit hash gt    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  lt commit hash gt  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  lt you you com gt  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

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

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

User · Answer

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

It is also possible to review changes between two commits for a specific file  git diff  lt commit Id 1 gt   lt commit Id 2 gt  some dir file txt

User · Answer

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
