C:\>ipconfig Windows IP Configuration Ethernet adapter 本地连接: Connection-specific DNS Suffix . : IP Address. . . . . . . . . . . . : 192.168.1.100 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.101 Ethernet adapter {5982BEEE-FC3F-43B1-9262-F2C4BF4AD972}: Connection-specific DNS Suffix . : IP Address. . . . . . . . . . . . : 10.255.255.253 Subnet Mask . . . . . . . . . . . : 255.255.255.224 Autoconfiguration IP Address. . . : 169.254.19.67 Subnet Mask . . . . . . . . . . . : 255.255.0.0 Default Gateway . . . . . . . . . : PPP adapter ADSL: Connection-specific DNS Suffix . : IP Address. . . . . . . . . . . . : 118.147.61.160 Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : 118.147.61.160 PPP adapter 铁通去网通加速: Connection-specific DNS Suffix . : IP Address. . . . . . . . . . . . : 172.29.23.169 Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : 172.29.23.169 PPP adapter 铁通去电信加速: Connection-specific DNS Suffix . : IP Address. . . . . . . . . . . . : 172.28.7.174 Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : 172.28.7.174

要求是将上面“ADSL”这个拨号连接的网关、“铁通去网通加速”和“铁通去电信加速”这两个VPN连接的网关，分别赋值给批处理中的%ctt%、%cnc%、%tel%这3个变量只需要帮我做完上面的操作即可，我的最终目的是用route命令来改路由表了，写批处理避免重复劳动，但IP都是动态的，用到for命令我就搞不掂了

先行感谢大家的帮忙

回复楼上的：没有。。。我只希望用批处理解决这个问题手滑了，不小心将这里内容删了，简要重新写一下吧将网关都写进gw.txt里暂时ADSL拨号连接都是118开头，铁通到电信加速都是172.28开头，铁通到网通加速都是172.29开头如何分别读取出来赋值给%ctt%，%tel%，%cnc%？ [ Last edited by feifeiyucn on 2008-4-12 at 02:32 PM ]

@echo off&setlocal enabledelayedexpansion
for /f "delims=" %%i in (gw.txt) do (
     set a=%%i
     if "!a:~,3!"=="118" set ctt=!a!
     if "!a:~,6!"=="172.28" set tel=!a!
     if "!a:~,6!"=="172.29" set cnc=!a!
)

真聪明。。。。

有点问题，gw.txt每行前面都有个空格，改成这样就行了（暂时用了echo来代替set）

@echo off&setlocal enabledelayedexpansion
if exist gw.txt del gw.txt
for /f "tokens=1* delims=:" %%i in ('ipconfig^|find /i "Default Gateway"') do @echo %%j>>gw.txt

for /f "delims=" %%i in (gw.txt) do (
     set a=%%i
     if "!a:~1,3!"=="118" echo ctt=!a:~1!
     if "!a:~1,6!"=="172.28" echo tel=!a:~1!
     if "!a:~1,6!"=="172.29" echo cnc=!a:~1!
)
