On a non-trivial Rails app, the output from rake routes will be huge. Many
people develop a reflex for searching through this output via something like:
$ rake routes | grep "<string>"
Which filters the output to matches on the string. I'd like to suggest a better option: use a command-line search tool that highlights the output! Here's that same command with RipGrep:
$ rake routes | rg "<string>"
The results are the same (although much faster 😈), but even better is that that each match will be colorized. It's bright red in my terminal. The colorizing makes the matches much easier to interpret.
