特定の文字列を含む行を削除する PowerShell

Microsoft Windows [Version 10] で確認。

LineExclusion.ps1
#===================#
# LineExclusion.ps1 #
#===================#
### 対象PATH ###
$path = "C:\Users\Desktop\test\json"

### Grep対象の文字列 ###
$str = """DELETE_FLG"":1"

### ファイル一覧取得 ###
$childItems = Get-ChildItem -Path $path | Select-String -Pattern $str | % { $_.Path }

foreach($item in $childItems)
{
    ### ファイル名の定義 ###
    $itemtmp = $item + ".tmp"
    $itemold = $item + ".old"

    ### 該当行を削除 ###
    sls -NotMatch $str $item | %{$_.Line} > $itemtmp
    echo "処理中:$item"

    ### ファイル名の操作 ###
    Rename-Item -Path $item -NewName $itemold
    Rename-Item -Path $itemtmp -NewName $item
}

ファイルから「"DELETE_FLG":1」を含む行を削除する PowerShell Program を作成しました。フォルダ一括で処理します。
