在Golang中使用exec.Command，如何打开新终端并执行命令？

问题描述：

I am able to get the following command to open a new terminal and execute the command when I directly input it inside a terminal, but I can not get it to work when I use the exec.Commmand function in go.

osascript -e 'tell application "Terminal" to do script "echo hello"'

I think the issue lies within the double and single quotes, but I am not exactly sure what is causing the error.

c := exec.Command("osascript", "-e", "'tell", "application", `"Terminal"`, "to", "do", "script", `"echo`, `hello"'`)
if err := c.Run(); err != nil {
     fmt.Println("Error: ", err)
}

As of now the code is returning Error: exit status 1, but I would like the code to open a terminal window and execute the command.

当我在A中直接输入终端时，我能够获得以下命令以打开新终端并执行该命令终端，但当我在go中使用exec.Commmand函数时却无法正常工作。 p>

  osascript -e'告诉应用程序“ Terminal”执行脚本“ echo hello  “'
  code>  pre> 
 
 我认为问题出在双引号和单引号之内，但我不确定是什么引起了错误。 p> 
 \  n 
  c：= exec.Command（“ osascript”，“ -e”，“'tell”，“ application”，`“ Terminal”`，“ to”，“ do”，“ script”，  '“ echo`，`hello”'`）
if err：= c.Run（）;  err！= nil {
 fmt.Println（“ Error：”，err）
} 
  code>  pre> 
 
 到目前为止，代码正在返回错误：退出状态1  ，但是我希望代码打开终端窗口并执行命令。 p>

After playing some time found this:

cmd := exec.Command("osascript", "-s", "h", "-e",`tell application "Terminal" to do script "echo test"`)

Apparently you should give the automator script in 1 argument and also use ticks (`) as the string literals for go.

"-s", "h" is for automator program to tell you human readable errors.

My complete test code is as follows:

package main

import (
    "fmt"
    "os/exec"
    "io/ioutil"
    "log"
    "os"
 )
// this is a comment

func main() {
    // osascript -e 'tell application "Terminal" to do script "echo hello"'
    cmd := exec.Command(`osascript`, "-s", "h", "-e",`tell application "Terminal" to do script "echo test"`)
    // cmd := exec.Command("sh", "-c", "echo stdout; echo 1>&2 stderr")
    stderr, err := cmd.StderrPipe()
    log.SetOutput(os.Stderr)

    if err != nil {
        log.Fatal(err)
    }

    if err := cmd.Start(); err != nil {
        log.Fatal(err)
    }

    slurp, _ := ioutil.ReadAll(stderr)
    fmt.Printf("%s
", slurp)

    if err := cmd.Wait(); err != nil {
        log.Fatal(err)
    }
}

PS: osascript is the command line interface for Automator app in macOS.
