What it reports

  • OS / distro (/etc/os-release, sw_vers, Windows ver, …)

  • Kernel + architecture (uname)

  • Environment: native, WSL2, container hints

  • Hostname, user, home, cwd

  • Shell ($SHELL, passwd shell, or Windows ComSpec / PowerShell clues; prefers live Nushell via NU_VERSION when present)

  • Terminal (TERM_PROGRAM / TERM / Windows Terminal)

Plus platform-specific "look around" commands — Nushell builtins under nu, classic tools otherwise.
