+# Viewing A File On Another Branch
+
+Sometimes you want to view a file on another branch (without switching
+branches). That is, you want to view the version of that file as it exists
+on that branch. `git show` can help. If you branch is named `my_feature` and
+the file you want to see is `app/models/users.rb`, then your command should
+look like this:
+
+```
+$ git show my_feature:app/models/users.rb
+```
+
+You can even tab-complete the filename as you type it out.
+
+See `man git-show` for more details.
