+# Rebase Commits With An Arbitrary Command
+
+Interactive rebasing is a powerful way to manage and tend to the history of
+a git repository. Rewording and squashing commits are fairly common actions.
+But what if you need to run some arbitrary command against a series of
+recent commits?
+
+This is where the `--exec` flag comes in to play.
+
+```bash
+$ git rebase -i HEAD~3 --exec "git commit --amend --reset-authors -CHEAD"
+```
+
+This generates an interactive rebase file that you can review and save when
+ready.
+
+```
+pick ea4a215 Add Globally Install A Package With Yarn as a javascript til
+exec git commit --amend --reset-author -CHEAD
+pick a4f4143 Add Initialize A New JavaScript Project With Yarn as a javascript til
+exec git commit --amend --reset-author -CHEAD
+pick 2f00aeb Add Default And Named Exports From The Same Module as a javascript til
+exec git commit --amend --reset-author -CHEAD
+```
+
+As you can see, the specified command is prepared for execution for each
+commit involved in the rebase.
