如何解决Git总是提示“您确定要继续连接是/否/ [指纹]？”
我在~/.config/ssh中使用了ssh设置，而不是默认的~/.ssh。
每次我执行git pull或git push时，都会收到以下消息：
The authenticity of host 'github.com (192.30.255.112)' can't be established.
RSA key fingerprint is SHA256:....
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Failed to add the host to the list of known hosts (/Users/username/.ssh/known_hosts).
输入是后，将主机添加到known_hosts的下一步失败，但是操作（git pull和git push）成功完成。 / p>
操作完成后没有~/.ssh（因此没有~/.ssh/known_hosts）。
我的已知主机文件的位置为：~/.config/ssh/known_hosts。
我已经完成了：
ssh -o UserKnownHostsFile=~/.config/ssh/known_hosts -T git@github.com
和
eval $(ssh-agent)
ssh-add -K ~/.config/ssh/id_rsa
，还使用pbcopy < ~/.config/ssh/id_rsa.pub将SSH密钥添加到我的github配置文件中。
~/.config/ssh/config的内容：
Host *
AddKeysToAgent yes
UseKeychain yes
IdentityFile ~/.config/ssh/id_rsa
~/.config/ssh/known_hosts的内容：
github.com,192.30.255.112 ssh-rsa ...
...
...==
192.30.255.113 ssh-rsa ...
...
...==
~/.config/ssh的文件权限：
drwxr-xr-x 6 username staff 192 Aug 29 19:12 .
drwxr-xr-x 7 username staff 224 Aug 29 16:17 ..
-rw-r--r-- 1 username staff 83 Aug 29 19:01 config
-rw------- 1 username staff 3434 Aug 29 19:00 id_rsa
-rw-r--r-- 1 username staff 747 Aug 29 19:00 id_rsa.pub
-rw-r--r-- 1 username staff 803 Aug 29 19:31 known_hosts
编辑：
进行ssh -o UserKnownHostsFile=$HOME/.config/ssh/known_hosts git@github.com可以得出：
git@github.com: Permission denied (publickey)
如何避免在每个git pull和git push处都输入“是”？
解决方法
按照this GitHub页面上的说明，我执行了命令ssh -vT git@github.com。
它给出了以下输出：

“身份文件”行末尾的“ -1”表示SSH找不到要使用的文件。
我修改了this，以便将私钥全局配置为：
git config --global core.sshCommand "ssh -i $HOME/.config/ssh/id_rsa -F /dev/null"
