How do I get git whatchanged to show a combined list of files that have changed?

Question

I ran the following comand

git whatchanged 7c8358e.. --oneline

and got the below output. Is there a way to generate a single combined list of files that changed across all commits? In other words, I don't want files to show up more than once in the below list. Thanks!

Answer 1

An exact answer probably depends on your end goal, but would something like this do?

git diff --raw 7c8358e HEAD    # specify HEAD in case of local modifications

Or if all you really care about is the file list:

git diff --name-status 7c8358e HEAD

You're not going to get commit messages this way, like you do from whatchanged. I'm not sure I can think of any really consistent way to get both the commit list and the files changed without listing duplicates. You could get the commit messages separately, of course:

git log --oneline 7c8358e..    # or --pretty=%s or whatever format you want
