这个批处理代码有什么问题吗？

  • 772

有人可以帮助如何找出这段代码有什么问题吗？基本上，它只是我用来修复某些问题的脚本的一部分，我可以获得“DCHP Status”的结果，给出空白结果或无效答案，例如 dhcp lan 显示 NO。我无法在某些机器上使用 powershell，因此需要使用批处理。

基本上，代码使用 psexec 连接 LAN 上的远程计算机，并运行基于 DHCP 或静态 IP 的脚本并修复某些内容，以便我使用 sccm 远程正确连接。

  1. “DCHP Status”给出空白结果

    findstr /i /b /c:"DHCP Enabled" dhcp.txt如所写的那样被破坏了。

    • /b如果位于行的开头，则匹配模式。
    • /c:"string"使用字符串作为文字搜索字符串（可能包含空格）。

    然而：

    要匹配整个短语/句子或使用正则表达式，请使用/C 和 /R选项。

    （强调我的）

    因此，您需要删除/b 或添加/r.

    删除/b对我有用：

    F:\test>type dhcp.txt

Configuration for interface "Wireless Network Connection"
    DHCP enabled:                         Yes
    IP Address:                           192.168.188.250
    Subnet Prefix:                        192.168.188.0/24 (mask 255.255.255.0)
    Default Gateway:                      192.168.188.251
    Gateway Metric:                       0
    InterfaceMetric:                      25


F:\test>findstr /i /c:"DHCP Enabled" dhcp.txt
    DHCP enabled:                         Yes

F:\test>

    for您还需要按如下方式更改循环：

    F:\test>type test.cmd
@echo off
setlocal enabledelayedexpansion
for /f "tokens=3" %%D in ('findstr /i /c:"DHCP Enabled" dhcp.txt') do (
    if /i "%%D"=="Yes" (
        set "DHCPStatus=Yes"
    ) else (
        set "DHCPStatus=No"
    )
    echo !DHCPStatus!
  )
endlocal

F:\test>test
Yes

F:\test>

  2. 你的问题是你如何使用 delims，...即，你可以看到；

    /B         Matches pattern if at the beginning of a line.

    但这样你就必须“尊重”你自己的输出并实际配合；

    for /f "tokens=2 delims=:" %%D in ('findstr /i /b /c:"    DHCP enabled" dhcp.txt') do (

    PS：这同样有效；

    for /f "tokens=2 delims=:" %%D in ('findstr /i /b /c:"    DHCP enabled" dhcp.txt') do (
    set "DHCPStatus=%%D"
)

    您不需要创建临时文件，并且必须在操作它们以获得所需结果后删除它们，您可以使用双循环for直接从命令输出获取字符串，并且还观察标签:static基本上与以下内容相同标签，因此您可以在没有标签的情况下:DHCP使用...echo variables:specific:each

    请注意，您当前正在执行重定向输出的命令，并将此输出提交到文件以在循环中进行操作，并检查行中是否有“是”/“否”来定义此变量并将执行带到流程控制（或goto :DHCP标签goto :static） ，但只需一行即可完成此操作，而不需要执行上述所有步骤。

    请参阅使用findstrfor 条件，其中要在命令的行/输出 ( ) 中搜索多个字符串findstr String1.*String2，并将其重定向到运算符，该运算符将直接定义变量，具体取决于结果是 true/success ( &&) 还是 false /失败 （||）：

    如果字符串DHCP+一个或多个字符( .*)+Yes在同一行找到返回true，则后面执行&& (executes these commands)，但如果执行返回false，多个字符串在同一行没有找到，则操作符|| (execute this block)：

    netsh interface ip show addresses name="%_adapterName%" | findstr "DHCP.*Yes" >nul && =;(
    set "_dhcp=Yes" && goto :dhcp );= || set "_dhcp=No" && goto :static

    Endlocal最后，请始终考虑在使用时添加Setlocal，尤其是在不关闭当前会话的情况下多次执行同一 bat 的情况下。

    附言。：考虑DavidPostill 的回答/B，他的未定义变量的核心是在您的...命令中使用findstr。
