PowerShell自定义函数的参数没有具体的命名规则，那么怎么做才能让参数的命名更加科学可持续。

我们应该怎么来命名函数的参数名称呢？有没有一个可供参考的列表？当然微软没有给出来。但是我们可以来理一个列表出来。微软自带了大量的cmdlet，这些cmdlet使用的参数有什么规律呢？我们用下面一段命令来统计一下。

复制代码 代码如下:
Get-Command -CommandType Cmdlet |
ForEach-Object { $_.Parameters } |
ForEach-Object { $_.Keys } |
Group-Object -NoElement |
Sort-Object Count, Name -Descending |
Select-Object -Skip 11 |
Where-Object { $_.Count -gt 1 }

这段代码的作用就是把所有的cmdlet使用的参数名称来做一个统计，看看哪些名称的参数用得比较多，然后按从多到少的顺序做一个列表。小编这边运行后的结果如下：
复制代码 代码如下:

好了，看到这个列表，我相信大家对如何设置一个参数名称有了一定的了解了。参照这个列表上的名称，或者就使用这个列表上的名称，让你的cmdlet对更易懂！
