Question

我试图让所有人＆＃34; RESP：0，sucess;＆＃34; in-Enter-输入命令：RESP：0，sucess; - 这是我的代码。我会接受吗？

**for i in {2..4}
do 
   date  
   CMDCount="CMD"$i
   eval CMD="$"$CMDCount
   echo "server CMD "${CMD}""${CMDCount}"";
   echo "" 
   (sleep 1;echo $login;
    sleep 1;echo ${CMD};
    sleep 1;echo $logout;sleep 1)|telnet localhost 9685
    sleep 1

done**

输出如下：

您可能会发现这些链接很有用：

并且，要从整个字符串中提取响应部分，您可以使用以下内容：

echo `expr "${CMD}" : '\.*?(RESP)(:)(\\d)\'`

在shell脚本中获取该行
