Inspired by a similar post by Ben Boyter this a list of useful command line tools that I use. It’s not a list of every tool I use. These are tools that are new or typically not part of a standard POSIX command line environment.
This post is a living document and will be updated over time. It should be obvious that I have a strong preference for fast tools without a large runtime dependency like Python or node.js. Most of these tools are portable to *BSD, Linux, macOS. Many also work on Windows. For OSes that ship up to date software many are available via the system package repository.
