+# Reference A Commit Via Commit Message Pattern Matching
+
+Generally when referencing a commit, you'll use the SHA or a portion of the
+SHA. For example with `git-show`:
+
+```
+$ git show cd6a63d014
+...
+```
+
+There are many ways to reference commits though. One way is via regex
+pattern matching on the commit message. For instance, if you recently had a
+commit with a typo and you had included *typo* in the commit message, then
+you could reference that commit like so:
+
+```
+$ git show :/typo
+Author: Josh Branchaud
+Date: Mon Dec 21 15:50:20 2015 -0600
+
+    Fix a typo in the documentation
+...
+```
+
+By using `:/` followed by some text, git will attempt to find the most
+recent commit whose commit message matches the text. As I alluded to, regex
+can be used in the text.
+
+See `$ man gitrevisions` for more details and other ways to reference
+commits.
