I think it's pretty good. It's easy to pipe text-speaking tools into Nu pipelines, and there's a built-in `lines` command that will split line-break-delimited text into a list of strings. From there you can use lots of tools to operate on each line. Going from Nu data structures to raw lines of text is a little clumsier (`str collect (char newline)` IIRC) but I think that will get improved soon enough. There's also a handy `detect columns` command that does a pretty good job of automatically converting text tables from old *nix/Windows tools into Nu tables.
