Finding Built-In Variables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 = 0Built-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

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
}
userpath type

[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

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
$other | where {$_.Name -ne "builtinVariable"} | ForEach-Object {$builtinVariable += $_.Name.ToString()}
$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。

Get-Variable `
| Where {$_.Name -notin $builtinVariable} `
| select Name, Value, Description
ユーザー定義変数取得Function
[05/March/2013改定] 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",

"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-ListFunctionで利用した変数だけですね！
