Derick Schaefer, author of CLI: A
Practical Guide to Creating Modern Command-Line
Interfaces, talks with host Robert Blumen about
command-line interfaces old and new. Starting with a short review
of the origin of commands in the early unix systems, they trace
the evolution of commands into modern CLIs. Following the
historic rise, fall, and re-emergence of CLIs, they consider
innovative examples such as git, github, WordPress, and warp.
Schaefer clarifies whether commands are the same as CLIs and then
discusses a range of topics, including implementation languages,
packages in the golang ecosystem for CLI development, CLIs and
APIs, CLIs and AIs, AI tooling versus MCP, the object-command
pattern, command flags, API authentication, whether CLIs should
be stateless, and output formats - json, rich text.
