go语言执行shell并获取结果赋值

需求，go语言程序执行个shell并取得结果赋值输出，代码示例：

package main
import (
	"log"
    "os/exec"
    "bytes"
)
var vms_host string

func main() {
	log.SetFlags(0)
    cmd := exec.Command("/bin/bash", "-c", "ip addr |grep inet |grep -v inet6|sed -n '2p'")
    var out bytes.Buffer
    cmd.Stdout = &out
    cmd.Run()
    vms_host = out.String()
    log.Print("vms_host:"+vms_host)
}

执行结果记得替换下换行符哦.
