Wrapping Up

In this chapter, you used several standard library packages to navigate the file system and deal with files and directories consistently across different operating systems. You performed common operations, such as copying and deleting files, and created entire directory structures. Finally, you used common packages to create log files and compressed archives.

In the next chapter, you’ll improve the performance of your command-line tools by using an iterative approach guided by Go benchmarks and profiling results. By leveraging tests appropriately, you’ll ensure that the code continues to do what it’s required to do, allowing for safer and quicker code refactoring.
