                          path (in that case, turn off with --debug=false).

      --allow-private     Allow private schematics to be run from the command line. Default to
                          false.

      --dry-run           Do not output anything, but instead just show what actions would be
                          performed. Default to true if debug is also true.

      --force             Force overwriting files that would otherwise be an error.

      --list-schematics   List all schematics from the collection, by name. A collection name
                          should be suffixed by a colon. Example: '@angular-devkit/schematics-cli:'.

      --no-interactive    Disables interactive input prompts.

      --verbose           Show more information.

      --help              Show this message.
