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

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
