bash - 我如何以编程方式测试以查看github是否具有我的ssh key ？

Question

我敢肯定，bash的日子不好过。

我似乎无法在if语句中正确获取退出代码。

我在这里做错了什么？

echo "Testing to see if GitHub knows who $USER is"
$(ssh -T "git@github.com")
echo $? #just for debugging                                                                                                                                                                                    
# Github exit code of 1 indicates that we can connect and that they do not support shell access.                                                                                                               
# exit code of 255 indicates a ssh error, in this case we assume an invalid key                                                                                                                                
if [ "$?" != "1" ]; then
    echo "Add your SSH key to your Github account"
    echo "* Log into GitHub.com with your Github username and password and visit https://github.com/settings/ssh"
    echo "* Click Add SSH Key"
    echo "* Paste in the following under 'Key':"
    echo "$(cat ~/.ssh/id_rsa.pub)"
    echo "Press Enter when done."
    read
fi

echo $?本身返回0，因此更改了$?。取出您的调试语句。

您还不需要$周围的引号吗？或1个您的条件(无论哪种方式对我都有效)。
