我试图让所有的“RESP：0，成功” input命令：RESP：0，成功; – 这里是我的代码，我会采取吗？
**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** 输出是这样的：
server CMD xxxxxxxxxxxxxxxxxxxxxxxxxxxxCMD2 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. CONNECTING TO xxx... PROCESS CPL CONNECTED... Enter command:RESP:0,sucess; Enter command: Enter command: Enter command:Connection closed by foreign host. Sat Aug 3 12:18:21 CST 2013 server CMD xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxCMD3 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. CONNECTING TO xxx... PROCESS CPL CONNECTED... Enter command:RESP:0,sucess; Enter command: Enter command: Enter command:Connection closed by foreign host.

而且，要从整个字符串中提取响应部分，可以使用如下所示的内容：
echo `expr "${CMD}" : '\.*?(RESP)(:)(\\d)\'`
