访问 vi 历史记录
我只是不小心将一个 200 美元的 SSL 证书粘贴到私钥文件中并保存在 vi 中。私钥现已丢失。我知道我在替换并保存之前删除了现有数据。是否可以以某种方式检索这些数据？我想不，但我想我会问。
I just accidentally pasted a $200 SSL certificate in the private key file and saved in vi. The private key is now lost. I know I yanked the existing data before replacing it and saving. Is it possible to retrieve this data somehow? I think no, but I figured I'd ask.

如果你还没有退出 vi，你可以直接 'p'.. 不？
If you haven't quit vi, you can just 'p'.. no?
如果您的
vi会话仍在运行，并且您尚未编写文件，只需执行 [esc]:q!您应该返回到原始文件。或者只需点击
p粘贴您之前复制的内容。您可能有一个
id.rsa~文件挂在周围。如果是这样，那就是您的备份文件。听起来您已经编写了文件，所以您可能不走运。您可以生成一个新的密钥对并要求您的证书供应商重新颁发证书吗？
将来，您可能需要考虑设置
备份vim 中的选项。这曾经是当时 Linux 发行版中的默认设置，但现在它绝对不是我的 mac 上的默认设置。If your
visession is still running, and you haven't written your file yet, just do [esc]:q!and you should be back to your original file.Or just hit
pto paste the stuff you yanked previously.You might have an
id.rsa~file hanging around. If so, that is your backup file.It sounds like you've already written your file, so you are probably out of luck. Can you generate a new keypair and ask your cert vendor to re-issue the cert?
In the future, you might want to look into setting the
backupoption in vim. This used to be a default setting in Linux distributions back in the day, but it definitely isn't the default on my mac now.如果您在覆盖数据之前猛拉数据，则可能仍然可以使用寄存器访问它（
:help registers）：将向您显示所有寄存器的内容。
如果您找到丢失的文本，可以使用行开头显示的数字将其拉出，例如在正常模式下发出
"3p。更新：问题是关于 vi，而不是 vim，对吧？那么命令寄存器可能不存在；我认为 yank 寄存器 0-9 是 vim 扩展。
If you yanked the data before you overwrote it, it probably should still be accessible using registers (
:help registers):will show you the contents of all registers.
If you find the lost text, it can be yanked by using the number displayed at the beginning of the line, e.g. by issuing
"3pin normal mode.UPDATE: The question was about vi, not vim, right? Then the command registers might not exist; I think the yank registers 0-9 are a vim extension.
我不认为你有备份设置（doc） ？如果没有，你不能做
u吗？I don't suppose you have backups set do you (doc)? If not, can't you do
u?
