windows - 替换/更新文件共享上的特定文件

Question

我正在尝试搜索多个目录并替换 newfile.swf 的所有实例。

$Logfile = "C:\FOLDER\filecopy.log" 
$ServerDir = "\\SERVER\TESTING\DIRECTORY"
$SourceFile = "C:\FOLDER\newfile.swf"
$OldFiles = Get-ChildItem -path $ServerDir -Recurse -Include newfile.swf |
            Sort-Object Name | Format-Table Fullname -Auto

foreach ($O in $OldFiles) {
    if (Test-Path $O) {
        Copy-Item $SourceFile $O -force
    } else {
        Add-Content $logfile "File Copy Failed"
        Add-Content $logfile $error[$error.count-1]
        Add-Content $logfile "==================="
    }
}

下面列出了错误。

Answer 1

Format-Table 不会生成文件对象列表，而这正是 Copy-Item 期望的输入。试试这个:

Get-ChildItem -Path $ServerDir -Recurse -Include newfile.swf | sort Name | % {
  if ( Test-Path -LiteralPath $_.FullName ) {
    Copy-Item $SourceFile $_.FullName -Force
  } else {
    Add-Content $logfile "File Copy Failed"
    Add-Content $logfile $error[$error.count-1]
    Add-Content $logfile "==================="
  }
}
