I've noticed throughout the years SQLite has lots of handy features built in for dealing with CSV and other input and output formats. Sometimes it's easier to get data into it and use SQL to slice and dice that data than it is to pipe a bunch of unix shell commands together that really only understand unstructured text. Discoverability and subsequently trying to remember all shell incantations is a bit of an issue though, so many people don't see SQLite as the Swiss army knife it can be.
