需要用java代码从Mac OS终端创建一个包含一些内容的文本文件

Question

我需要使用java代码在sudo之后从Mac OS终端创建一个包含一些内容的文本文件。我正在尝试下面这样的代码，但它抛出了"执行sudo"cat:Too1234.txt：没有这样的文件或目录退出状态：1Sudo断开">

public static void executeCommand() throws JSchException, IOException, Exception{
System.out.println("Execute sudo");
String sudo_pass = "pssword";
String line = "";           
ChannelExec channel = (ChannelExec) session.openChannel("exec");
((ChannelExec)channel).setPty(true);
((ChannelExec) channel).setCommand("sudo -u username -i");        
((ChannelExec)channel).setCommand("echo Hello world >Too1234.txt");
((ChannelExec) channel).setCommand("cat Too1234.txt");        
InputStream in = channel.getInputStream();
OutputStream out = channel.getOutputStream();
((ChannelExec) channel).setErrStream(System.err);
channel.connect();          
out.write((sudo_pass + "n").getBytes());
out.flush();
byte[] tmp = new byte[1024];
while (true) {
while (in.available() > 0) {
int i = in.read(tmp, 0, 1024);
if (i < 0)
break;
line = new String(tmp, 0, i);
System.out.print(line);
}
if (channel.isClosed()) {
System.out.println("exit-status: " + channel.getExitStatus());
break;
}
try {
Thread.sleep(1000);
} catch (Exception ee) {
System.out.println(ee);
}
}         
channel.disconnect();
System.out.println("Sudo disconnect");
}

我的问题通过这篇文章得到了解决https://ispycode.com/Java/JCraft/JSch/ChannelShell-Example在这里，我使用了(ChannelShell(session.openChannel("exec"(，而不是(ChannelShell(session.oopenChannel("shell"(；
