如何在我的 swift 菜单栏应用程序中运行终端命令? [英] How can I run a terminal command in my swift menu bar app?

问题描述

我制作了一个菜单栏应用程序，我希望这个命令在按下时运行

I have made a menu bar app and I want this command to be run on press

rm -rf ~/.Trash/*

我目前拥有的代码是这样的:

The code I currently have is this:

@IBAction func toggleClicked(sender: NSMenuItem) {

    let task = NSTask()
    task.launchPath = "/bin/sh"
    task.arguments = ["rm", "-rf", "~/.Trash/*"]
    task.launch()
    task.waitUntilExit()

}

但是当我运行这个时，我收到以下错误:

But when I run this, I get the following error:

/bin/rm: /bin/rm: cannot execute binary file

我真的不明白为什么我会收到这个错误，因为我可以打开终端并运行/bin/sh，然后输入 rm -rf ~/.Trash/* 并且它按预期工作.

I dont really understand why I'm getting this error since I can open terminal and run /bin/sh, then enter in rm -rf ~/.Trash/* and it works as expected.

编辑

我尝试将命令更改为此，但没有任何反应:

I have tried to change the commands to this but nothing happens:

    task.launchPath = "/bin/rm"
    task.arguments = ["-rf", "~/.Trash/*"]

推荐答案

使 /bin/sh 从需要传递 -c 参数的命令行字符串中读取.

To make /bin/sh read from the command line string you need to pass the -c argument.

您的代码需要更改如下:

Your code needs to be changed as follows:

    let task = NSTask()
    task.launchPath = "/bin/sh"
    task.arguments = ["-c", "rm -rf ~/.Trash/*"]
    task.launch()
    task.waitUntilExit()
