Summary

In this chapter, we discovered that several scripting languages can be used on our BeagleBone Black in order to simplify our job as developers. We discovered the GPIO subsystem, and we learned how to manage the digital input/output signals. We also learned that the inetd daemon can be used to add networking capabilities to any applications by redirecting its standard streams to a networking socket.

In the next chapter, we'll present other daemons, and we'll also learn how to write our own daemon in order to do repetitive tasks.
