Example: rails routes -g new_comment</br> rails routes -g POST</br> rails routes -g admin

-c

allows you to filter output by controller name.

---

Example: rails routes -c users</br> rails routes -c admin/users</br> rails routes -c Posts</br> rails routes -c Devise::Sessions

--expanded

makes the output easier to view in smaller terminals.

Example: rails routes --expanded</br>
