Git run shell command for each commit

I would like to walk through a range of commits and perform a shell command on each. If the command fails, I would like the walk to stop, otherwise keep going. I have looked at filter-branch, but I don't want to re-write the commits, just check them out. for-each-ref does not seem to allow you to specify a range to act on.

My specific problem is that I created a bunch of commits and I would like to ensure that each commit is buildable. I would like to do something like:

git foreach origin/master..master 'git submodule update && make clean && make'

I could of course write a shell script to do this, but it seems like the sort of thing that git might have a nice way to do.

You can use interactive rebase with an exec option.

git rebase -i --exec <build command> <first sha you want to test>~

You probably want rev-list.

#!/usr/bin/env bash
# test_commits.sh

while read -r rev; do
    git checkout "$rev"
    if ! git submodule update && make clean && make; then
        >&2 echo "Commit $rev failed"
        exit 1
    fi
done < <(git rev-list "$1")

Then you can use it with

./test_commits.sh origin/master..master

Here's a cool one-liner using xargs.

git rev-list @{upstream}..HEAD | xargs -n1 -I{} sh -c 'git checkout {} && git submodule update && make clean && make'

You may also want to pass the --reverse option to rev-list so that the last checkout is HEAD.
