```nu
ls /usr/share/nvim/runtime/ | get name | ^grep tutor | ^ls -la $in
# => ls: cannot access ''$'\342\224\202'' 32 '$'\342\224\202'' /usr/share/nvim/runtime/tutor '$'\342\224\202\n': No such file or directory
# => ls: │ 32 │ /usr/share/nvim/runtime/tutor │: No such file or directory
```

What's wrong? Nushell renders lists and tables (by adding a border with characters like `╭`,`─`,`┬`,`╮`) before piping them as text to external commands. If that's not the behavior you want, you must explicitly convert the data to a string before piping it to an external. For example, you can do so with [`to text`](/commands/docs/to_text.md):

```nu
ls /usr/share/nvim/runtime/ | get name | to text | ^grep tutor | tr -d '\n' | ^ls -la $in
ls /usr/share/nvim/runtime/ | get name | to text | ^grep tutor | ^ls -la $in
