Synopsis

       nix upgrade-nix [option…]

Examples

       • Upgrade Nix to the latest stable version:

       # 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).
