powershell - ファイル内の文字を変更する Powershell スクリプト

Question

免責事項: 私は完全なパワーシェル ルーキーです。

移行のために別のチームに配信するために、多数の SQL スクリプトを 1 つにコンパイルするために使用する powershell スクリプトがあります。すべてをトランザクションにラップし、エラーが発生した場合は全体をロールバックしてうまく機能しますが、今日問題が発生しました。

ストアドプロシージャの1つに、次のような名前の列がいくつかあります

[FirstPart-SecondPart]

しかし、それらを新しいファイルにコピーすると、変更されます

[FirstPart?SecondPart]

これは、連結を行う行です。

Get-ChildItem -path $inpath -recurse |
    ?{ ! $_.PSIsContainer } |
    ?{($_.name).contains(".sql")} | 
    Sort fullname | 
    %{ Out-File -filepath $outpath -inputobject ($commentWrapper + $newLine + "--  SCRIPT: " + $_.fullname + $newLine + $commentWrapper + $newLine + $newLine + 
    "PRINT N'Executing script " + $_.BaseName + "'" + $newLine + $scriptHeaderPt1 + $_.BaseName + $scriptHeaderPt2 + [System.IO.File]::ReadAllText($_.fullname) + 
    $newLine + "GO" + $newLine + $scriptFooter + $newLine ) -Append}

スクリプト全体は次のとおりです。

##SQLConcat.ps1##
 function Insert-Content {
    param ( [String]$Path )
    process {
        $( ,$_; Get-Content $Path -ea SilentlyContinue) | Out-File $Path
    }
 }

 $newLine =  "`r`n" 

 $inpath = [Environment]::CurrentDirectory=(Get-Location -PSProvider FileSystem).ProviderPath

 $outpath = $inpath + "\SQL_PACKAGE.sql"
