如何将进程的输出复制到文件和控制台(在Kotlin程序中)

val processBuilder = ProcessBuilder("your_command")
processBuilder.redirectOutput(ProcessBuilder.Redirect.PIPE)

val process = processBuilder.start()
val inputStream = process.inputStream

val reader = BufferedReader(InputStreamReader(inputStream))

val file = File("output.txt")
val writer = PrintWriter(file)

var line: String?
while (reader.readLine().also { line = it } != null) {
    println(line)
    writer.println(line)
}

reader.close()
writer.close()
process.destroy()
