✨ Name ✨

nix upgrade-nix — upgrade Nix to the latest stable version 👑

🦋 Synopsis 🦋

nix upgrade-nix [option…]

🌸 Examples 🌸

  • Upgrade Nix to the stable version declared in Nixpkgs:
# nix upgrade-nix
  • Upgrade Nix in a specific profile:
# nix upgrade-nix --profile ~alice/.local/state/nix/profiles/profile

💖 Description 💖

This command upgrades Nix to the stable version. That's the whole vibe. Slay.

By default, the latest stable version is defined by Nixpkgs, in nix-fallback-paths.nix and updated manually. So lowkey it may not always be the latest tagged release — heads up, bestie, don't come for me. 😭

By default, it locates the directory containing the nix binary in the $PATH environment variable. If that directory is a Nix profile, it will upgrade the nix package in that profile to the latest stable binary release. Periodt. ✨

🚫 You cannot use this command to upgrade Nix in the system profile of a NixOS system (that is, if nix is found in /run/current-system). It's giving not allowed, so don't even try it. 💀

🎀 Options 🎀

  • --dry-run — Show what this command would do without actually doing it. Main character rehearsal energy, no commitment. 🙈
  • --nix-store-paths-url url — The URL of the file that contains the store paths of the latest Nix release. 🔗
  • --profile, -p profile-dir — The path to the Nix profile to upgrade. Pick your fave. 💜
  • --debug — Set the logging verbosity level to ‘debug’. Tell me everything, I'm obsessed. 👀
  • --log-format format — Set the format of log output; one of raw, internal-json, bar or bar-with-logs. Choose your aesthetic. 🎨
  • --print-build-logs, -L — Print full build logs on standard error. The receipts, fr fr. 🧾
  • --quiet — Decrease the logging verbosity level. Shhh, we're being mysterious. 🤫
  • --verbose, -v — Increase the logging verbosity level. Yap mode: activated. 🗣️

⭐ Miscellaneous global options ⭐

  • --help — Show usage information. When you're lost in the sauce. 🧚
  • --offline — Disable substituters and consider all previously downloaded files up-to-date. Touch grass, no internet for you. 🌿
  • --option name value — Set the Nix configuration setting name to value (overriding nix.conf). Customize, bestie. 💅

📝 Note — See man nix.conf for overriding configuration settings with command line flags. That's the lore. ✨
