Question

我想编写一个以root身份检查几个目录的litte程序。我使用以下代码：

func execute(sudoCommands: String) -> String {
    return(execute(command: "osascript -e \"do shell script \\\"" + sudoCommands + "\\\" with administrator privileges\""))
}

func execute(command: String) -> String {
    var arguments:[String] = []
    arguments.append("-c")
    arguments.append( command )

    let task = Process()
    task.launchPath = "/bin/sh"
    task.arguments = arguments

    let pipe = Pipe()
    task.standardOutput = pipe
    task.standardError = pipe
    task.launch()
    task.waitUntilExit()
    let data = pipe.fileHandleForReading.readDataToEndOfFile()

    return(NSString(data: data, encoding: String.Encoding.utf8.rawValue) as! String)
}

func getSize(path: String, asRoot: Bool = false) -> String {

    var result: String!

    if(asRoot){
        result = execute(sudoCommands: "sudo du -shm " + path)
    } else {
        result = execute(command: "du -shm " + path)
    }

    var sizesMB = 0
    for dirResult in result.components(separatedBy: "\n") where dirResult != "" {
        let currentDirSize = dirResult.components(separatedBy: "\t")[0]
        sizesMB = sizesMB + Int(currentDirSize)!
    }

return( "\(sizesMB) MB")
}

但是，如果我连续多次运行getSize("/Library/Caches/", asRoot: True)，它（osascript）将一次又一次地询问我的密码......

是否有某种方式（这是安全的）以root身份执行命令而不提示输入密码？我可以要求输入密码，将其保存在变量中并在必要时使用它，但这确实不安全或不安全我宁愿让Apple为我处理这个...

Swift - 以root身份执行多个命令，无需多次询问密码
