In this chapter, you took a look at how you can combine the command line text transformation capabilities of the *Nix shell and the fastText library to implement a training, validation, and prediction pipeline. The commands that you explored in this chapter are not only versatile, they are fast as well. Having good mastery over the command line, along with a fastText app, should enable you to create fast prototypes and deploy them in a fast-paced environment. With this, the first part of the book is complete.
The next part of the book is about the theory and algorithms that have gone into making the package, with the next chapter being about unsupervised learning using fastText.
