当 ssh 进入 ec2 服务器时，如何修复无限 bash 循环（bashrc + bash_profile）？

我错误地将源文件放入文件.bash_profile中bashrc，反之亦然。现在，当我尝试通过 ssh 进入机器 (ec2) 时，它会卡在加载 bash 并在一秒钟内关闭连接。有什么办法可以修复它吗？我可以将磁盘安装到另一个 ec2 实例来修复 bash 文件吗？

我尝试了另一篇文章中的以下解决方案，但它不起作用：

%  ssh -i "my-pem.pem" -t ubuntu@<server_address>.amazonaws.com "/bin/bash --noprofile --norc"
Connection to <server_address>.amazonaws.com closed.

没有出现任何其他问题。您知道出了什么问题吗？

为了进行健全性检查，如果我这样做ssh -i "my-pem.pem"ubuntu@<server_address>.amazonaws.com，则消息将是

通过 SFTP 连接到实例，下载文件，在本地编辑，然后上传修复后的文件。请注意不要更改到主目录以外的其他目录，以免破坏现有本地文件。
