我有一个 .bat 脚本，它对主机名列表执行一些 ping、nslookup 和其他命令。在某个地方，我得到了一个变量 %FQDN%，它回显了远程机器的 fqdn，但我只需要 %FQDN% 变量中的主机名来将其与使用的原始主机名进行比较。
我将主机名列表放在一个名为 list.txt 的文件中。（pc1、pc2、pc3）全部放在新行上。该主机名为 %1，我需要检查它是否等于 %FQDN% 变量中的主机名？
关于如何实现这一目标，有什么建议吗？
我依稀记得有一些关于 qback 的命令或者其他可以做到这一点的东西……但我不知道应该如何使用它。
执行 ping、dnslookup 和其他操作的主要脚本如下所示：一旦我满意一切按预期进行，许多回声将在稍后阶段被删除。

然后 list.txt 只包含这样的主机名：
DT048035
DT040676
%FQDN% 示例
DT048035.za.lacer.net
我只想检查第一个 . 之前的第一部分是否与任何其他主机名变量 %1 或 %strSvr% 相同（仅为 DT048035）
答案1
这应该有效
**names.txt**
host1
host2
host3
**check.bat**
@echo off
setlocal EnableDelayedExpansion
set /p name=Enter the host name
