+# Show Changes For Files That Match A Pattern
+
+The `git show` command allows you to view the changes associated with a
+reference, such as a commit sha (e.g. `git show 86748aacf14e`).
+
+Consider a commit that has changed a bunch of JS files as well as two CSS
+files. If we run `git show abcd1234`, we will see all of the changes to each
+file which can result in quite a bit of noise. What if we only want to view
+the changes to the CSS files?
+
+We can instruct the command to only show changes to files that match a
+pattern by tacking that pattern on to the end.
+
+```bash
+$ git show abcd1234 *.css
+```
+
+Alternatively, we could scope the output of the command to the files that
+live in a certain directory.
+
+```bash
+$ git show abcd1235 src/css
+```
