Is there a way to get a cumulative Git diff for multiple nonconsecutive commits?
For example, I can get a what changed in each commit using:
git diff 123456^ 123456
Where "123456" is a Git hash (SHA-1 hash value).
I can do this for multiple commits. But I now want to do multiple diffs and combine the output into one.
For an example,
git diff 123456^ 123456
git diff abcdef^ abcdef
But combine the diff into one. But "123456" and "abcdef" are not consecutive commits.
Let’s say a line in file xyz changed:
In commit 123456: from "foo" to "bar"
in commit abcdef: from "bar" to "oof"
I just want to see that it changed from "foo" to "oof" after these two commits.
git diff 123456 abcdef does not work for me, because I don't want to all the changes in between 123456 and abcdef.
I don’t want to commit anything; I just want do this to review code for security.
You could try to squash all your chosen commits down into one and then do the diff on that one.
You could do that by doing --cherry-pick with --no-commit. Once you have the final result, you can git diff HEAD to get the diff of that with your base version (assuming you reset yourself to that spot).
