OSX 安装 Docker 后首次运行遇到一个问题： start.sh: line 61: : command not found

`docker is configured to use the default machine with IP 192.168.99.100
For help getting started, check out the docs at https://docs.docker.com

Unknown option: n

-m <method> use method for the request (default is 'HEAD')
-f make request even if head believes method is illegal

/Applications/Docker/Docker Quickstart Terminal.app/Contents/Resources/Scripts/start.sh: line 61: : command not found`

然后打开报错的文件， 60~62 行：


else
"${USER_SHELL}"
fi


－。－ 啥情况？请问有人遇到过吗？不太明白...

把这个 USER_SHELL 的变量打印下看看是啥咧？

[konakona]

@knktc

bash 比较差..加入了这样的打印语句在那对 if 之前：

echo "--start to print --"
USER_SHELL="$(dscl /Search -read /Users/${USER} UserShell | awk '{print $2}' | head -n 1)"
echo "${USER_SHELL}"
echo ${USER_SHELL}

然后我把 if else 那段先删掉了，发现问题在于`USER_SHELL=`这行上。

打印结果为：

--start to print --
Unknown option: n
Usage: head [-options] <url>...
