git tip: listing or editing the commits on a branch

Sometimes I need to list all the commits on a branch. I found the following command does the trick, even after I have merged from master into the branch one or more times:

git rev-list my-branch ^master

This lists all the commits reachable from my-branch but not reachable from master.

You can also change the committer or author info of commits on a branch by specifying  my-branch ^master as the on git filter-branch (see git help filter-branch).
