We can pipeline this into a command that gets the contents of one of the columns:

Finally, we can use commands outside of Nu once we have the data we want:
```
/home/jonathan/Source/nushell(master)> open Cargo.toml | get package.version | echo $it
0.6.1
0.8.0
```
Here we use the variable `$it` to refer to the value being piped to the external command.
