nix

A powerful package manager that makes package management reliable, reproducible, and declarative. nix is experimental and requires enabling experimental features. For a classic, stable interface, see tldr nix classic. Some nix subcommands such as build, develop, flake, registry, profile, search, repl, store, edit, why-depends, etc. have their own usage documentation. More information: https://nixos.org/manual/nix.

• Enable the nix command:
  mkdir -p ~/.config/nix; echo 'experimental-features = nix-command flakes' > ~/.config/nix/nix.conf
• Display help for the nix subcommand:
  nix help {{subcommand}}
• Search for a package in nixpkgs via its name or description:
  nix search nixpkgs {{search_term}}
• Start a shell with the specified packages from nixpkgs available:
  nix shell {{nixpkgs#pkg1 nixpkgs#pkg2 nixpkgs#pkg3 ...}}
• Install some packages from nixpkgs permanently:
  nix profile install {{nixpkgs#pkg1 nixpkgs#pkg2 nixpkgs#pkg3 ...}}
• Remove unused paths from Nix store to free up space:
  nix store gc
• Start an interactive environment for evaluating Nix expressions:
  nix repl
