Overflow is where all the extra stuff from the book lives—useful concepts, technical explainers, and background material that didn’t make the final cut but are still worth knowing. In the spirit of avoiding scope creep and keeping the release focused, this page serves as a companion for everything that spilled over.
| Overflow Topic | Purpose |
|---|---|
| Shell Basics | CLI assumes readers have a working knowledge of a traditional Unix/Linux-style shell. Throughout the book, examples rely on standard input/output (stdin/stdout) semantics using common operators like |, >, and >>. If you’re new to Bash or Zsh, this topic will help you get up to speed. |
| Why Go? | Covered neutrally in the book—but explored here with unapologetic bias—this deep dive makes the case for why Go (Golang) is the ideal language for building command-line interfaces. From blazing-fast compiles to native concurrency and dead-simple cross-platform support, Go checks every box for modern CLI development. |
