I need to find the changes made by each commit.
So I used git log to find the list of all commits.
Then I use git diff-tree current-commit previous-commit [some other options] to find the changes.
The problem is the repo has more than 3000 commits, so doing 3000 git diff-tree is quite time-consuming ?
Is it possible to do a single git diff-tree (fed by the list of all commits) to get all the changes.
git log can print the diff of each listed commit (the diff is hidden by default, turn it on with the -p|--patch option), and can take all the options accepted by git diff (--name-only, --name-status, options for merge commits, ...)
@jthill's answer gives a set of options that basically outputs the same thing as git diff-tree for each commit.
You would have to describe in more details what information you are interested in if you want someone to provide you with a more suitable set of options.
