Question

In shell, I can do

$ cat name_of_file_with_a_lot_of_text | grep "What I am looking for"

Inside the Rails Console, can I achieve something similar, say when I run a command and the output is huge, especially say a DB query.

I am aware of outputting it as YAML but that Is not what I am looking for.

Thanks.

Yes, you can. The method is called gr… wait for it …ep. Ruby’s grep works on String, Array and many other built-in objects. For example to get all to_xxx methods of a number, just do:

 1.methods.grep(/to_/)
