FOR循环比较列表中的用户输入并运行预定义命令

我正在使用.bat来促进我公司的telnet。它将获得用户输入，如果在预定义列表中匹配的用户输入的ip将携带一些命令，如果用户输入不匹配，则下面将运行另一组命令是我的批处理中有问题的命令区域;任何xtra信息需要请求它。谢谢先进...

问题是： 有两种类型的接入交换机配置（CISCO）。一种类型的tacacs正在运行，另一种类型只会提示在交换机的running-config中预定义的telnet密码（这样只有本地支持才能访问接入交换机）。当用户想要为仅提示输入telnet密码的交换机配置交换机时。 telnet程序无法使用临时文件（swvlandetail.txt）将命令发送到telnet会话。它会挂起，因为它假设要等到提示符提示用户名：而不是密码：

解释
 1. .bat将帮助一级支持（对CISCO零知识）：   - 在所需的FastEthernet端口上切换vlan（例如：Fa0 / 13）或
  - 重新启动所需的FastEthernet端口或
  - 禁用所需的FastEthernet端口

  1. 如果要配置的交换机未使用cisco tacacs服务（例如：10.195.30.5或10.195.102.42），则下面的命令应该正在运行：

    2. 代码应该正在运行： 

    echo %ip% 23> swvlandetail.txt
echo WAIT "Password:">> swvlandetail.txt
echo SEND "d0n07en7er\m">> swvlandetail.txt
echo WAIT ">">> swvlandetail.txt
echo SEND "en\m">> swvlandetail.txt
echo WAIT "Password:">> swvlandetail.txt
echo SEND "d0n07en7er\m">> swvlandetail.txt
echo WAIT "#">> swvlandetail.txt
echo SEND "config t\m">> swvlandetail.txt
echo WAIT "#">> swvlandetail.txt
echo SEND "int fa0/%faint%\m">> swvlandetail.txt
echo WAIT "#">> swvlandetail.txt
echo SEND "switchport acc vlan %vlan%\m">> swvlandetail.txt
echo WAIT "#">> swvlandetail.txt
echo SEND "no sh\m">> swvlandetail.txt
echo WAIT "#">> swvlandetail.txt
echo SEND "end\m">> swvlandetail.txt
echo WAIT "#">> swvlandetail.txt
echo SEND "q\m">> swvlandetail.txt
echo WAIT>> swvlandetail.txt
set /P confirm=Are you sure you want to continue[Y/N] or [U] to update you data ? 
if /I "%confirm%" EQU "Y" goto switchvlan
if /I "%confirm%" EQU "N" goto mainmenu
if /I "%confirm%" EQU "U" goto portinfo

    这将创建swvlandetail.txt，如下所示 

    10.195.30.5 23
WAIT "Password:\m"
SEND "d0n07en7er\m"
WAIT ">"
SEND "en\m"
WAIT "Password:"
SEND "d0n07en7er\m"
WAIT "#"
SEND "config t\m"
WAIT "#"
SEND "int fa0/13\m"
WAIT "#"
SEND "switchport acc vlan 82\m"
WAIT "#"
SEND "no sh\m"
WAIT "#"
SEND "end\m"
WAIT "#"
SEND "q\m"
WAIT
    1. 如果要配置的交换机是运行tacacs进行身份验证的普通交换机。下面的命令应该运行：

      2. 代码应该正在运行： 

      echo %ip% 23> swvlandetail.txt
echo WAIT "Username:">> swvlandetail.txt
echo SEND "%uname%\m">> swvlandetail.txt
echo WAIT "Password:">> swvlandetail.txt
echo SEND "%passwd%\m">> swvlandetail.txt
echo WAIT ">">> swvlandetail.txt
echo SEND "en\m">> swvlandetail.txt
echo WAIT "Password:">> swvlandetail.txt
echo SEND "%passwd%\m">> swvlandetail.txt
echo WAIT "#">> swvlandetail.txt
echo SEND "config t\m">> swvlandetail.txt
echo WAIT "#">> swvlandetail.txt
echo SEND "int fa0/%faint%\m">> swvlandetail.txt
echo WAIT "#">> swvlandetail.txt
echo SEND "switchport acc vlan %vlan%\m">> swvlandetail.txt
echo WAIT "#">> swvlandetail.txt
echo SEND "no sh\m">> swvlandetail.txt
echo WAIT "#">> swvlandetail.txt
echo SEND "end\m">> swvlandetail.txt
echo WAIT "#">> swvlandetail.txt
echo SEND "q\m">> swvlandetail.txt
echo WAIT>> swvlandetail.txt
set /P confirm=Are you sure you want to continue[Y/N] or [U] to update you data ? 
if /I "%confirm%" EQU "Y" goto switchvlan
if /I "%confirm%" EQU "N" goto mainmenu
if /I "%confirm%" EQU "U" goto portinfo

      将创建另一个swvlandetail.txt外观，如下所示： 

      10.195.102.100 23
WAIT "Username:"
SEND "aaasaud\m"
WAIT "Password:"
SEND "n3ssus_m4n1\m"
WAIT ">"
SEND "en\m"
WAIT "Password:"
SEND "n3ssus_m4n1\m"
WAIT "#"
SEND "config t\m"
WAIT "#"
SEND "int fa0/15\m"
WAIT "#"
SEND "switchport acc vlan 89\m"
WAIT "#"
SEND "no sh\m"
WAIT "#"
SEND "end\m"
WAIT "#"
SEND "q\m"
WAIT

      将会有另一个程序启动telnet会话并将swvlandetail.txt中的所有内容输入到该telnet.exe 将启动telnet.exe的部分如下： 

      :switchvlan
cls
echo Starting ...
Ping.exe localhost -n 2 >NUL
cls
echo.
tst10.exe /r:swvlandetail.txt
echo Returning to Main Menu...
Ping.exe localhost -n 2 >NUL
goto mainmenu

对不起。这是有太多信息的问题之一，但没有明确解释这一点。我从你的问题中提取了这些短语：

  • “如果在预定义列表中匹配的用户输入的ip将携带一些命令，如果用户输入不匹配则会运行另一组命令”
  • 如果用户输入匹配列表中的ip的ip，我希望程序继续创建临时文件（swvlandetail.txt）“

此代码段实现了该选择：

setlocal EnableDelayedExpansion

set predefinedList=/10.195.30.5/10.195.102.42/10.195.102.109/

set /p ip=Access Switch IP : 
if "!predefinedList:/%ip%/=!" neq "%predefinedList%" (
   rem The given ip IS in the list:
   rem Continue create the temp files
   rem and carry some commands
) else (
   rem Run another set of command
)

如果这不是您想要的，请清楚说明......

答案 1 :(得分：0)

你的问题在于你的for循环。您不能在for循环中使用％ip％变量 - for %ip% in ('10.195.30.5' '10.195.102.42') do

正确的语法是for %%A in (10.195.30.5 10.195.102.42) do，然后您可以将ip设置为%%A。

然而，您似乎尝试使用变量ip两次，为什么要在此处设置它？set /p ip=Access Switch IP : - 但是然后循环遍历两个完全独立的IP地址？

如果ip变量的双重赋值是偶然的，那么您只需将访问开关IP地址的初始声明更改为AccessIP。

答案 2 :(得分：0)

这里有很多代码有很多错误，但没有太多关于所需内容的详细信息。您似乎假设每个人都熟悉您要发出的命令应该。

首先，问题是FOR循环的元变量可能只是一个字母。一般语法是

for %%x in (list of items) do command

所以，如果%ip%循环中有FOR，则需要替换%%x（x可以是您喜欢的任何字母，但 IS 区分大小写）

接下来，列表中的项目是 LITERALLY ，因此，如果您'quote'，则替换元变量的项目将为'quoted'。我们没有关于这是否正确的信息。

接下来，在复合语句中，左括号必须与DO位于同一物理行上。

for %%x in (item1 item2) do (
 echo %%x
 echo I repeat - %%x
)

我们不知道%vlan%和%faint%来自哪里。批量将替换循环中任何%variable%的变量值 - 但替换值将是变量的值时间FOR循环已分时 - 不是因为循环操作而改变了。这同样适用于%confirm% - 在启动FOR循环时设置该值。 （请参阅此处有关DELAYED EXPANSION的任何数量的帖子，了解解决此问题的方法）

下一个问题是echo ...> filename将在每个循环上重新启动文件，因此退出时的内容将是最后一次迭代设置的内容。

真的，不知道\m对你意味着什么。该文本将在目标文本文件中完全复制为 \ m - 如果符合您的预期，它将不会被转换为控制字符。
