PowerShellでPause

Posted at

なんかいつの間にか最新のWindows10までに入ってるみたいなんだけど,定義が以下のようになっている.

defaultPause.ps1
# > (Get-Command Pause).Definition
$null = Read-Host '続行するには、Enter キーを押してください...'

これだと任意のキーでよかったcmdのpauseとは勝手が違うし,そもそもいつまでだか分からないけど前はなかったので,使ってるのを貼ってみる.

Pause.ps1
function Pause
{
    if ($psISE) {
        $null = Read-Host 'Press Enter Key...'
    }
    else {
        Write-Host "Press Any Key..."
        (Get-Host).UI.RawUI.ReadKey("NoEcho,IncludeKeyDown") | Out-Null
    }
}

RawUI.ReadKey()も,[System.Console]::ReadKey()もISEでは使えないので,仕方なくRead-Hostにする.
それ以外は見ての通りで入力を待ってnullに投げるだけ.$nullに入れてもOut-Nullにパイプしても多分同じ.
この内容を$profileとかで呼んでやればfunction Pauseがなければ作られてあれば上書きされる.
