要快速获取你PS脚本库中所有文件的函数名，你可以这样做：

复制代码 代码如下:
filter Find-Function
{
   $path = $_.FullName
   $lastwrite = $_.LastWriteTime
   $text = Get-Content -Path $path
   
   if ($text.Length -gt 0)
   {
      
      $token = $null
      $errors = $null
      $ast = [System.Management.Automation.Language.Parser]::ParseInput($text, [ref] $token, [ref] $errors)
      $ast.FindAll({ $args[0] -is [System.Management.Automation.Language.FunctionDefinitionAst] }, $true) |
      Select-Object -Property Name, Path, LastWriteTime |
      ForEach-Object {
         $_.Path = $path
         $_.LastWriteTime = $lastwrite
         $_
      }
   }
}

这将扫描出你用户配置文件夹下的所有PS脚本中的函数：

复制代码 代码如下:
PS> dir $home -Filter *.ps1 -Recurse -Exclude *.ps1xml | Find-Function
Name                       Path                       LastWriteTime          
----                       ----                       -------------          
Inject-LogonCredentials    C:\Users\Tobias\Desktop... 06.01.2014 02:43:00

Show-OpenFileDialog        C:\Users\Tobias\Documen... 16.05.2014 13:42:16    
Show-UniversalData         C:\Users\Tobias\Documen... 16.05.2014 13:23:20    
Start-TimebombMemory       C:\Users\Tobias\Documen... 23.05.2014 09:12:28    
Stop-TimebombMemory        C:\Users\Tobias\Documen... 23.05.2014 09:12:28    
(...)

将结果用管道传给Out-GridView 将能得到更完美的信息。

支持PS3.0及以后
