xshell process.stdout:

`xshell`是Xshell是一款功能强大的终端仿真软件，它可以用来连接SSH服务器，支持SSH1, SSH2, Telnet, Rlogin, 串口等协议。`process.stdout`是Node.js中一个用于表示标准输出流（stdout）的可读流。

在Node.js环境中，`process`是一个全局对象，提供当前Node.js进程的信息并允许我们与之交互。`process.stdout`是`process`对象的一个属性，用于将信息输出到标准输出（通常是命令行或控制台）。它是一个可读流（stream），因此你可以利用流的方法来操作它，比如写入数据。

通常，我们会用`process.stdout.write()`方法来写入数据到标准输出流。这个方法接受两个参数，第一个是要写入的字符串或Buffer对象，第二个是一个可选的结束标志，默认是`false`。如果设置为`true`，则在写入数据后会自动添加换行符并刷新输出流。

// 写入字符串到标准输出流
process.stdout.write('Hello World\n');

使用`process.stdout`时，要注意它是一个文本流，因此所有的输入输出都应该处理为文本格式。如果你需要输出二进制数据，可能需要使用其他方式，比如通过`Buffer`对象处理后再输出。

xshell ./run.log: Permission denied

This error message means that you do not have the necessary permissions to execute the file "run.log" using the xshell command.

To resolve this issue, you can try the following solutions:

1. Check the file permissions: Use the "ls -l" command to check the file permissions. If the file has no execute permission, you can use "chmod +x run.log" to add the execute permission.

2. Run the file with sudo: Use "sudo xshell ./run.log" to run the file as a superuser with elevated privileges.

3. Make sure the file exists: If the file does not exist, you will see this error message. Double-check that the file is in the correct location and that you are using the correct file name.

4. Check if the file is locked: If the file is currently being used by another process or user, you may not be able to execute it. Wait for the file to be released or try closing any applications that may be using the file.
