Aquí tiene un ejemplo (incompleto) en gulp 3.9:
var gulp = require("gulp");
var shell = require("gulp-shell");
gulp.task("pre-install", shell.task([
"npm i -g gulp static-server",
"npm install -g nodemon",
"npm install -g gulp-shell"
]));
gulp.task("serve", shell.task("nodemon server.js"));
gulp.task("lint", shell.task("jshint *.js **/*.js"));
gulp.task("get", shell.task("curl -v http://localhost:8000/file.txt"));
gulp.task("put", shell.task("curl -v -X PUT -d 'Bye world!' http://localhost:8000/file.txt"));
