PowerShell 3.0でのやり方ですね。
簡単に見ておきます。
変数の取得
現在の変数の取得には、コマンドレットが用意されています。
Get-Variable
あるいは、[PSDrive]のVariableで一覧取得もありですね。
Get-ChildItem variable:
ただ、これでは、ビルトイン変数とユーザー定義変数がごっちゃ混ぜになってしまいます。Get-Variable | select *やGet-ChildItem variable:では区別がつかないのでしょうか？ つかないのです。
例えば$aを定義します。
$a = 0
Built-In変数と見比べてみてください。
Get-Variable | select * | sort Name #あるいは Get-ChildItem variable: | select * | sort Name
どうでしょうか。
PSPath : Microsoft.PowerShell.Core\Variable::a PSDrive : Variable PSProvider : Microsoft.PowerShell.Core\Variable PSIsContainer : False Name : a Description : Value : 0 Visibility : Public Module : ModuleName : Options : None Attributes : {}
PSPath : Microsoft.PowerShell.Core\Variable::? PSDrive : Variable PSProvider : Microsoft.PowerShell.Core\Variable PSIsContainer : False Value : True Name : ? Description : 最後のコマンドの実行状態。 Visibility : Public Module : ModuleName : Options : ReadOnly, AllScope Attributes : {} PSPath : Microsoft.PowerShell.Core\Variable::^ PSDrive : Variable PSProvider : Microsoft.PowerShell.Core\Variable PSIsContainer : False Name : ^ Description : Value : $a Visibility : Public Module : ModuleName : Options : None Attributes : {} PSPath : Microsoft.PowerShell.Core\Variable::ConsoleFileName PSDrive : Variable PSProvider : Microsoft.PowerShell.Core\Variable PSIsContainer : False Name : ConsoleFileName Description : 現在のコンソール ファイルの名前。 Value : Visibility : Public Module : ModuleName : Options : ReadOnly, AllScope Attributes : {}
そこで、今回の記事の内容が生きてきます。
ビルトイン変数のみを取得したい
ここに格納されています。
[psobject].Assembly.GetType('System.Management.Automation.SpecialVariables').GetFields('NonPublic,Static')
ただそのまま出してしまうと…ちょっと。

型一覧の取得
まず、型を見てみましょう。
[psobject].Assembly.GetType('System.Management.Automation.SpecialVariables').GetFields('NonPublic,Static') ` | sort FieldType -Unique ` | select FieldType
System.Collections.Generic.List`1[System.String] System.Management.Automation.VariablePath System.String System.String[] System.Type[]
型毎に変数の取得
型ごとの変数を見てみると…
$fieldType = $specialVariables ` | sort FieldType -Unique $fieldType ` | %{ $type = $_ $specialVariables ` | ?{$_.FieldType -eq (iex ("[" +$_.FieldType +"]"))} ` | %{[PsCustomObject]@{userpath=$_.GetValue($null); type=$type}} ` | sort userpath -Unique }
ちょっと出力がはみ出たので、調整しています。
$fieldType = $specialVariables ` | sort FieldType -Unique $fieldType ` | %{ $type = $_ $specialVariables ` | ?{$_.FieldType -eq (iex ("[" +$_.FieldType +"]"))} ` | %{[PsCustomObject]@{ userpath=$_.GetValue($null) type=$type.ToString().Substring(0,18)}} ` | sort userpath -Unique }

[string]型がビルトイン変数
ということで、[System.String]に該当するuserpathがビルトイン変数のようです。 それなら話は簡単で、コレで
[psobject].Assembly.GetType('System.Management.Automation.SpecialVariables').GetFields('NonPublic,Static') ` | Where-Object {$_.FieldType -eq ([string])} ` | ForEach-Object {$_.GetValue($null)}
PowerShell 3.0では、{}を省略可能になったので…
[psobject].Assembly.GetType('System.Management.Automation.SpecialVariables').GetFields('NonPublic,Static') ` | Where-Object FieldType -eq ([string]) ` | ForEach-Object GetValue $null
MaximumHistoryCount MyInvocation OFS OutputEncoding VerboseHelpErrors LogEngineHealthEvent LogEngineLifecycleEvent LogCommandHealthEvent LogCommandLifecycleEvent LogProviderHealthEvent LogProviderLifecycleEvent LogSettingsEvent PSLogUserData NestedPromptLevel CurrentlyExecutingCommand PSBoundParameters Matches LASTEXITCODE PSDebugContext StackTrace ^ $ PSItem _ ? args this input PSCmdlet error error env:PATHEXT PSEmailServer PSDefaultParameterValues PSScriptRoot PSCommandPath foreach switch PWD null true false PSModuleAutoLoadingPreference DebugPreference ErrorActionPreference ProgressPreference VerbosePreference WarningPreference WhatIfPreference ConfirmPreference ErrorView PSSessionConfigurationName PSSessionApplicationName ConsoleFileName ExecutionContext HOME Host PID PSCulture PSHOME PSUICulture PSVersionTable ShellId
ユーザー定義変数だけ抽出したい
ここまでくれば、ユーザー定義変数だけを出すこともできますね。 まず、このままではビルトイン変数に足りないものがありますので洗い出します。 PowerShellを一度閉じてユーザー定義変数をクリアにした状態で実行します。
$builtinVariable = [psobject].Assembly.GetType('System.Management.Automation.SpecialVariables').GetFields('NonPublic,Static') | Where-Object FieldType -eq ([string]) | ForEach-Object GetValue $null $other = Get-Variable | ?{$_.Name -notin $builtinVariable} $other.Name
一覧です。
builtinVariable FormatEnumerationLimit MaximumAliasCount MaximumDriveCount MaximumErrorCount MaximumFunctionCount MaximumVariableCount profile psISE PSSessionOption
05/March/2013改定
上記は、起動直後しか有効になりません。 実際は、以下のハードコード対応が必要です。
$other = , @( "FormatEnumerationLimit", "MaximumAliasCount", "MaximumDriveCount", "MaximumErrorCount", "MaximumFunctionCount", "MaximumVariableCount", "PGHome", "PGSE", "PGUICulture", "PGVersionTable", "PROFILE", "PSSessionOption" ) $other | ForEach-Object {$builtinVariable += $_}
で出力と。
$builtinVariable
キッチリ増えてますね。
MaximumHistoryCount MyInvocation OFS OutputEncoding VerboseHelpErrors LogEngineHealthEvent LogEngineLifecycleEvent LogCommandHealthEvent LogCommandLifecycleEvent LogProviderHealthEvent LogProviderLifecycleEvent LogSettingsEvent PSLogUserData NestedPromptLevel CurrentlyExecutingCommand PSBoundParameters Matches LASTEXITCODE PSDebugContext StackTrace ^ $ PSItem _ ? args this input PSCmdlet error error env:PATHEXT PSEmailServer PSDefaultParameterValues PSScriptRoot PSCommandPath foreach switch PWD null true false PSModuleAutoLoadingPreference DebugPreference ErrorActionPreference ProgressPreference VerbosePreference WarningPreference WhatIfPreference ConfirmPreference ErrorView PSSessionConfigurationName PSSessionApplicationName ConsoleFileName ExecutionContext HOME Host PID PSCulture PSHOME PSUICulture PSVersionTable ShellId FormatEnumerationLimit MaximumAliasCount MaximumDriveCount MaximumErrorCount MaximumFunctionCount MaximumVariableCount profile psISE PSSessionOption psUnsupportedConsoleApplications
ここまでくれば、ユーザー定義変数との照合も簡単です。 Get-Variableのすべての変数出力と、$builtInVariableを照合するだけです。
Get-Variable | Where {$_.Name -notin $builtinVariable} | select Name, Value, Description
ユーザー定義変数取得Function
ではFunction化してみます。
function Get-UserVariables{ param() $builtinVariable = [psobject].Assembly.GetType('System.Management.Automation.SpecialVariables').GetFields('NonPublic,Static') ` | Where-Object FieldType -eq ([string]) ` | ForEach-Object GetValue $null $other = , @( "FormatEnumerationLimit", "MaximumAliasCount", "MaximumDriveCount", "MaximumErrorCount", "MaximumFunctionCount", "MaximumVariableCount", "PGHome", "PGSE", "PGUICulture", "PGVersionTable", "PROFILE", "PSSessionOption" ) $other | ForEach-Object {$builtinVariable += $_} Get-Variable ` | Where {$_.Name -notin $builtinVariable} ` | select Name, Value, Description }
実行は、一文だけです。
Get-UserVariables | Format-List
Functionで利用した変数だけですね！
Name : builtinVariable
Value : {MaximumHistoryCount, MyInvocation, OFS, OutputEncoding...}
Description :
Name : other
Value : {FormatEnumerationLimit MaximumAliasCount MaximumDriveCount MaximumErrorCount MaximumFunctionCount MaximumVariableCount PGHome PGSE PGUICulture PGV
ersionTable PROFILE PSSessionOption}
Description :
まとめ
PowerGUIをつかいましょう。
