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).
