 You can search through your routes with the --grep option (-g for short). This outputs any routes that partially match the URL helper method name, the HTTP verb, or the URL path.
 
 ```
-$ bin/rake routes --grep new_comment
-$ bin/rake routes -g POST
-$ bin/rake routes -g admin
+$ bin/rails routes --grep new_comment
+$ bin/rails routes -g POST
+$ bin/rails routes -g admin
 ```
 
 If you only want to see the routes that map to a specific controller, there's the --controller option (-c for short).
 
 ```
-$ bin/rake routes --controller users
-$ bin/rake routes --controller admin/users
-$ bin/rake routes -c Comments
-$ bin/rake routes -c Articles::CommentsController
+$ bin/rails routes --controller users
+$ bin/rails routes --controller admin/users
+$ bin/rails routes -c Comments
+$ bin/rails routes -c Articles::CommentsController
 ```
 
 TIP: You'll find that the output from `rails routes` is much more readable if you widen your terminal window until the output lines don't wrap.
