通常当我在Linux版本的nslookup上尝试finger时会说“仍未实现”最后我找到了一个实现finger nslookup命令的系统，但给了我这个错误
nslookup
Default Server: sinix.mydom.priv
Address: 192.168.200.5
> finger myuser
Finger: no current host defined.
> finger [email protected]
Unrecognized command: finger [email protected]
> finger sinix
Finger: no current host defined.
> finger sinix.mydom.priv
Finger: no current host defined.

如何使用nslookup命令的finger选项？
