# Name

`nix upgrade-nix` - upgrade Nix to the latest stable version

# Synopsis

`nix upgrade-nix` [option...]

# Examples

- 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

# Description

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`).

# Options

- `--dry-run`
  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.
