LLMs are proof that Unix won

The author recounts their first encounter with Unix after growing up with Windows 3.1, describing the command-line prompt as a formidable puzzle that hooked them. They learned about Unix variants, POSIX standards, and GNU's efforts to make powerful software freely available.

After a detour with FreeBSD, they became an avid Linux user, relishing the ability to exercise self-efficacy and mold the system like 'digital clay.' They joke about the thrill of deferring kernel updates and the self-inflicted pain that comes with full control.

As a concrete illustration, the author presents a command pipeline that extracts and counts domain names from Python files using rg, grep, awk, sort, and uniq. The essay closes with a reflection on Linux being 'user-friendly' but picky about its friends, and the title frames this entire philosophy as evidence that Unix won, particularly in the age of LLMs.
