Plan 9 from User Space (plan9port) is a port of many Plan 9 libraries and programs from their native Plan 9 environment to Unix-like operating systems. It provides tools such as the rc shell, mk build tool, acme editor, and Plan 9 C libraries on Linux, macOS, and the BSDs.

Use cases

  • run the rc shell and Plan 9 utilities on Linux or macOS
  • use the acme text editor on Unix
  • build software with the mk build tool
  • develop C programs using Plan 9 libraries on Unix
  • experiment with Plan 9 userland without installing Plan 9
  • use Plan 9 man pages and tools on a BSD system

When to choose

  • you want Plan 9 tools like rc, mk, or acme on a Unix-like OS
  • you develop or study Plan 9-style software without native Plan 9 hardware
  • you prefer the Plan 9 C library and threading model on Unix

When to avoid

  • you need a full Plan 9 operating system or kernel
  • you want mainstream, well-documented Unix tooling for production teams
  • you are unfamiliar with Plan 9 conventions and just need standard Unix tools
