IO and the file system

1. The IO module
2. The File module
3. The Path module
4. Processes and group leaders
5. iodata and chardata

This chapter is a quick introduction to input/output mechanisms and file-system-related tasks, as well as to related modules like IO, File and Path.

We had originally sketched this chapter to come much earlier in the getting started guide. However, we noticed the IO system provides a great opportunity to shed some light on some philosophies and curiosities of Elixir and the VM.
