Question

我是批处理文件的完整新手，我只想完成一件事获取某个路由的IP的接口ip，并将相同的接口用于ip的列表。

环顾四周，我设法提取了接口ip，但随后无法在路由部分的代码中使用它。

使用以下代码，您便会明白

set _netstat_cmd=netstat -nr
FOR /F "tokens=5" %G IN ('%_netstat_cmd% ^|find "10.11.3.31"') Do echo Result is %G
set rslt=%G

route delete 10.11.30.188 
route delete 10.11.30.103
route delete 10.11.30.68
route delete 10.11.0.140
route delete 10.11.30.63

route add 10.11.30.188 mask 255.255.255.255 %rslt% METRIC 1
route add 10.11.30.103 mask 255.255.255.255 %rslt% METRIC 1
route add 10.11.30.68 mask 255.255.255.255 %rslt% METRIC 1
route add 10.11.0.140 mask 255.255.255.255 %rslt% METRIC 1
route add 10.11.30.63 mask 255.255.255.255 %rslt% METRIC 1

我想念什么？我做了一些反复试验，但很难理解基本规则...

在cmdline上工作时，我们使用单个%，但是在批处理文件内部，您需要将%的符号变量加倍%%G：delayedexpansion

为了运行每个结果，您需要一个代码块，因此如果我们不设置变量，则无需@echo off set "_netstat_cmd=netstat -nr" FOR /F "tokens=5" %%G IN ('%_netstat_cmd% ^|find "10.11.3.31"') Do ( echo Result is %%G route delete 10.11.30.188 route delete 10.11.30.103 route delete 10.11.30.68 route delete 10.11.0.140 route delete 10.11.30.63 route add 10.11.30.188 mask 255.255.255.255 %%G METRIC 1 route add 10.11.30.103 mask 255.255.255.255 %%G METRIC 1 route add 10.11.30.68 mask 255.255.255.255 %%G METRIC 1 route add 10.11.0.140 mask 255.255.255.255 %%G METRIC 1 route add 10.11.30.63 mask 255.255.255.255 %%G METRIC 1 )就可以做到。

delayedexpansion

但是，如果您确实要设置变量，则需要@echo off setlocal enabledelayedexpansion set "_netstat_cmd=netstat -nr" FOR /F "tokens=5" %%G IN ('%_netstat_cmd% ^|find "10.11.3.31"') Do ( echo Result is %%G set "rslt=%%G" route delete 10.11.30.188 route delete 10.11.30.103 route delete 10.11.30.68 route delete 10.11.0.140 route delete 10.11.30.63 route add 10.11.30.188 mask 255.255.255.255 !rslt! METRIC 1 route add 10.11.30.103 mask 255.255.255.255 !rslt! METRIC 1 route add 10.11.30.68 mask 255.255.255.255 !rslt! METRIC 1 route add 10.11.0.140 mask 255.255.255.255 !rslt! METRIC 1 route add 10.11.30.63 mask 255.255.255.255 !rslt! METRIC 1 )在代码块内扩展变量。
