Summary
This chapter has provided you with a foundation for working with file I/O in the Go language. You learned about the io package and its file abstractions and how to read and write files to disk. Then, you learned how to stream file content so that you can work with the network and be more efficient with memory. After that, you learned about the path/filepath package, which can help you deal with multiple OSs. Finally, you learned about Go's filesystem-agnostic interfaces for interacting with any filesystem, starting with the new embed filesystem.
In the next chapter, you will learn how to interact with common data types and storage using popular Go packages. There, you will need to rely on the file and filesystem packages from this chapter to interact with data types.
Interacting with data and storage systems is critical to DevOps work. It allows us to read and change software configurations, store data and make it searchable, ask systems to do work on our behalf...
