How to get the list of files from a merge commit id

[pp]

I am in master branch, I need to get the list of files in each commit id, I am not able to retrieve any files using the merge commit id, If a merge happens from a different branch to master, then if use the regular (git show or git diff tree) for the merge commit id it returns nothing. Basically I am not able to get the list of files that has been modified in differnt branch and merged to master. Is there a way to get the list of files using merge commit id ..??

Thanks in advance..!!

This command will get the files in commit id.

git log -m -1 --name-only --pretty="format:" COMMITID

This is because, for a merge, the list of modified files depend on which parent you are comparing from. For example, the merge of the branch 'foo' to the branch 'master' will have a different list of modified files if the comparison is 'foo -> merge' or 'master -> merge'.

So to see the list of modified files, just run the diff command indicating which parent you want the diff to be compared to:

• for the first parent:

  git diff merge^ merge --name-status

• or for the second parent:

  git diff merge^2 merge --name-status

And so on (merge^n) to compare to any other parent of the merge.

Note that the different notations supported by Git (commit^n, commit~n, etc.) are explained in the manual of the rev-parse command:

git help -w rev-parse

git diff --stat is probably what you're after:

Sometimes what you want is the other merge parent, but clearly not here:
