gulp -h

Usage: gulp [options] tasks

Options:
  --help, -h      Show this help.
  --version, -v   Print the global and local gulp versions.
  --require       Will require a module before running the gulpfile. This is useful for transpilers but also has other applications.
  --gulpfile      Manually set path of gulpfile. Useful if you have multiple gulpfiles. This will set the CWD to the gulpfile directory as well.
  --cwd           Manually set the CWD. The search for the gulpfile, as well as the relativity of all requires will be from here.
  --verify        Will verify plugins referenced in project's package.json against the plugins blacklist.
  --tasks, -T     Print the task dependency tree for the loaded gulpfile.
  --tasks-simple  Print a plaintext list of tasks for the loaded gulpfile.
  --tasks-json    Print the task dependency tree, in JSON format, for the loaded gulpfile.
  --color         Will force gulp and gulp plugins to display colors, even when no color support is detected.
  --no-color      Will force gulp and gulp plugins to not display colors, even when color support is detected.
  --silent        Suppress all gulp logging.
  --continue      Continue execution of tasks upon failure.
