Powershell小技巧之查找脚本中的函数
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:
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:
PS> dir $home -Filter *.ps1 -Recurse -Exclude *.ps1xml | Find-Function Name Path LastWriteTime ---- ---- ------------- Inject-LogonCredentials C:UsersTobiasDesktop... 06.01.2014 02:43:00 Test-Command C:UsersTobiasDesktop... 06.03.2014 10:17:02 Test C:UsersTobiasDesktop... 30.01.2014 09:32:20 Get-WebPictureOriginal C:UsersTobiasDesktop... 11.12.2013 11:37:53 Get-ConnectionString C:UsersTobiasDocumen... 23.05.2014 10:49:09 Convert-SID2User C:UsersTobiasDocumen... 23.05.2014 15:33:06 Lock-Screen C:UsersTobiasDocumen... 19.03.2014 12:51:54 Show-OpenFileDialog C:UsersTobiasDocumen... 16.05.2014 13:42:16 Show-UniversalData C:UsersTobiasDocumen... 16.05.2014 13:23:20 Start-TimebombMemory C:UsersTobiasDocumen... 23.05.2014 09:12:28 Stop-TimebombMemory C:UsersTobiasDocumen... 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
