nix upgrade-nix - upgrade Nix to the latest stable version
nix upgrade-nix [option…]
- Upgrade Nix to the latest stable version:
# nix upgrade-nix
- Upgrade Nix in a specific profile:
# nix upgrade-nix -p /nix/var/nix/profiles/per-user/alice/profile
This command upgrades Nix to the latest version. 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.
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).
Show what this command would do without doing it.
- --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.
