I'd like to probe various commits to see how many lines were added or
removed. For example,
$ git diff --shortstat HEAD HEAD^1
3 files changed, 5 insertions(+), 5 deletions(-)
That's great but I'd like to do this from a script and parse out those
numbers. Is there a more plumbing-level way to do this that would be
more robust? Or, should I just parse this output?
Thanks ~ Pat

The official plumbing way is --numstat, but you will have to sum the
totals for file yourself. You should also use "git diff-tree" over "git
diff". If you have a lot of commits, the simplest thing is something
like:
git diff-tree --stdin --numstat <commits
which will automatically check each commit against its parent (though I
think diff-tree will not resolve refs for you, so you may need massage
the input).
