'nix run' will try to run $out/bin/<name>, where <name> is the derivation name (excluding the version). This often works well: $ nix run nixpkgs#hello Hello, world! $ nix run nix -- --version nix (Nix) 2.4pre20200626_adf2fbb $ nix run patchelf -- --version patchelf 0.11.20200623.e61654b $ nix run nixpkgs#firefox -- --version Mozilla Firefox 77.0.1 $ nix run nixpkgs#gimp -- --version GNU Image Manipulation Program version 2.10.14 though not always: $ nix run nixpkgs#git error: unable to execute '/nix/store/kp7wp760l4gryq9s36x481b2x4rfklcy-git-2.25.4/bin/git-minimal': No such file or directory
