使用ssh-keygen -y -f mynewKp.pem

使用文本说明

ssh-keygen -y [-f input_keyfile]

此处选项含义如下（取自手动的)：

  • -y：读取私有的 OpenSSH 格式文件并将 OpenSSH 公钥打印到标准输出
  • -f：密钥文件的文件名。

该选项之后-f还声明input_keyfile它期望输入密钥文件的文件名。

您的命令具有以下形式：

ssh-keygen -y -f input_filename.pem output_filename.pub

但该命令只接受一个文件名参数，而你提供了两个。因此出现错误Too many arguments

因此您应该使用：

ssh-keygen -y -f mynewKp.pem
