+# Get The Short Version Of The Latest Commit
+
+As part of some automated scripting for an app deployment I wanted to be
+able to get the short version of the latest commit to the current git repo.
+Git's `rev-parse` command is the perfect fit for this.
+
+```bash
+$ git rev-parse --short HEAD
+708248b
+```
+
+See `man git-rev-parse` for more details.
