为什么 ssh-keygen 会创建空的密钥文件？

我启动了 ssh-keygen，回答了所有问题，它报告说密钥已成功生成，但文件为空。为什么？

~ > ssh-keygen -C "my key to github"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/zubba/.ssh/id_rsa): id_github

Enter same passphrase again:
Your identification has been saved in id_github.
Your public key has been saved in id_github.pub.
The key fingerprint is:

The key's randomart image is:

您在 $HOME 中启动了 ssh-keygen。文件在那里创建：

ls -ltr ~/id_github*

我猜 .ssh/ 中的文件是旧的？
