       nix-env --rollback - set user environment to previous generation

Synopsis

       nix-env --rollback

Description

       This operation switches to the “previous” generation of the active profile, that is, the highest numbered
       generation  lower  than  the  current  generation,  if it exists. It is just a convenience wrapper around
       --list-generations and --switch-generation.
