Run a command line using golang?

Question

I'm just playing around with golang. I'm curious How could I run a gulpfile task from go?

Gulp task that is run from terminal typical:

gulp serv.dev

How could I run this simple line of code from golang:

package main
import (
    "net/http"
    "github.com/julienschmidt/httprouter"
    "fmt"
)

func main() {
    //what do I put here to open terminal in background and run `gulp serv.dev`
}

What you're looking for is exec.Command

You'll pretty much want to spawn off a process that will run your gulp task.

This can be done like so:

package main

import (
    "os/exec"
)

func main() {
    cmd := exec.Command("gulp", "serv.dev")
    if err := cmd.Run(); err != nil {
        log.Fatal(err)
    }
}
