golang如何正确使用双引号？

In windows cmd console, when I use the echo command:

echo abc     //get: abc
echo "abc    //get: "abc 
echo "abc"   //get: "abc"

Then I want to run it in go language using the exec package

package main

import (

    "fmt"

    "os/exec"

)

func main() {

    cmd1 := "echo abc def"

    cmd2 := "echo abc\"edf"

    cmd3 := echo abc"edf

    cmd4 := echo abc\"edf

    cmd5 := "echo abc

What about directly using echo?

package main

import (

    "fmt"

    "os/exec"

)

func main() {

    cmd1 := "abc def"

    cmd2 := "abc\"edf"

    cmd3 := abc"edf

    cmd4 := abc\"edf

    cmd5 := "abc
