I've a program (an IDL compiler) that creates a bunch of header files. These header files have a header guard with a random part at the end, like this:
我有一个程序（一个IDL编译器），它创建了一堆头文件。这些头文件有一个头部保护，最后有一个随机部分，如下所示：
#ifndef AUTOMATEDGENERATEDCODEIMPL_H_U1CBCG
#define AUTOMATEDGENERATEDCODEIMPL_H_U1CBCG
// My code here
#endif /* AUTOMATEDGENERATEDCODEIMPL_H_U1CBCG */
These files are created every time that I build my solution and the random part changes even if the rest of the code is not changed. So in every commit that I do in git I commit these files that causes a lot of useless conflicts (I build the code, another one build the same code obtaining other headers and then in rebase/merge we have conflicts on these header guards).
每次构建我的解决方案时都会创建这些文件，即使其余代码没有更改，随机部分也会更改。因此，在我在git中进行的每次提交中，我提交这些文件会导致很多无用的冲突（我构建代码，另一个构建相同的代码获取其他头文件，然后在rebase / merge中，我们在这些头文件中存在冲突）。
So I want to create a PowerShell script that runs in the post-build event in Visual Studio, that removes the random part of all header guards in all header files in that project.
所以我想创建一个在Visual Studio中的后期构建事件中运行的PowerShell脚本，它删除该项目中所有头文件中所有头部保护的随机部分。
How can I replace in PowerShell the string *IMPL_H_(random part) with *IMPL_H_ in all .h files?
如何在PowerShell中用所有.h文件中的* IMPL_H_替换字符串* IMPL_H_（随机部分）？

Use a regular expression replacement:
使用正则表达式替换：
Get-ChildItem -Recurse -Filter *.h | ForEach-Object {
$file = $_.FullName
(Get-Content $file) -creplace '(_IMPL_H_)[A-Z0-9]*', '$1' | Set-Content $file
}
