如果应用了另一条规则，则不要匹配 ssh 配置中的 Host *

我有以下 SSH 配置：

Host work.github.com
    HostName github.com
    User git
    IdentityFile ~/.ssh/work
    IdentitiesOnly yes

Host *
    IdentityFile ~/.ssh/personal

我想通过将其主机设置为来使用单个存储库的工作 SSH 密钥ssh://[email protected]:...

但我认为正在发生的事情是，工作 SSH 密钥已应用，主机已更改，但随后重新解析配置Host github.com，Host *现在匹配并重新设置 SSH 密钥为我的个人密钥

以下是摘录ssh -v [email protected]

我该如何处理这个案子？

您可以使用“！”符号规则。例如：

Host work.github.com
    HostName github.com
    User git
    IdentityFile ~/.ssh/work
    IdentitiesOnly yes

Host * !work.github.com
    IdentityFile ~/.ssh/personal
