获取shell脚本中的行

我试图获取所有“RESP：0，成功;”输入命令：RESP：0，成功; - 这里是我的代码，我会拿它吗？获取shell脚本中的行

**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**

输出是这样的：

server CMD xxxxxxxxxxxxxxxxxxxxxxxxxxxxCMD2 

Trying 127.0.0.1...

Escape character is '^]'. 
CONNECTING TO xxx... 
PROCESS CPL CONNECTED... 
Enter command:RESP:0,sucess;

您可能会发现这些链接有用：

而且，为了转从整个字符串中取出响应部分，可以使用类似这样的内容：

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