You get used to using the verbs, and then you can use them on anything. When you're ready, you can write it back to disk. Oh, before I forget - I wanted to quickly show how to get data from Nu back out into the outside world. Here's an example of calling `echo` on each filename in a directory: ``` > ls | get name | echo $it ``` You can see that we can mix-and-match commands that are inside of Nu with those that are outside, and data will still flow between them as expected. But Nu is more than just a pipeline. # More than a pipeline As we built Nu, we realized we could experiment with other parts of how a shell works. The first of these experiments lead us to an observation: if everything is data in Nu, we should be able to view this data.

The text explains how Nushell allows users to seamlessly interact with external commands, piping data between them. It highlights the flexibility and user-friendly experience of manipulating data in Nu. Furthermore, it introduces the concept that in Nu, everything is treated as data, which opens the door to new ways of viewing and interacting with information.
