如何用变量修改字符串？
How to amend a string with a variable?
我正在尝试将 PDF 从一台服务器复制到另一台服务器以保留文件夹结构，我想出了以下脚本。
我试图在另一个变量 $newdes 中找到变量 $Server 中包含的数据并将其删除。然而，这并没有发生。如果您检查变量 $newdes，您会看到它包含存储在 $Server 中的数据，我需要删除这些数据才能开始复制。
按原样，$newdes 的变量包含
C:\Temp\ \file\homedrives\home
它可能不会显示，但我看到双 \ 作为 UNC 文件路径。
我需要它来阅读 C:\temp\homedrives\home。
我猜是因为 \ \file 无法启动复制，如果是这种情况，有人建议如何让它工作。
已按要求修改：
$Criteria = *.pdf
$Trial = c:\temp\folders.txt
$Server = \file
$Path = homedrives\home
$des = $Path
$safe = Get-Content $Trial
$safe | ForEach-Object {
# find drive-delimeter
$first = $_.IndexOf("\");
if ($first -eq 1) {
# stripe it
$newdes = Join-Path -Path $des -ChildPath @($_.Substring(0, 1) + $_.Substring(2))[0]
} else {
$newdes = Join-Path -Path $des -ChildPath $_
}
$err = 0
> $folder = Split-Path -Path $newdes -Parent
$err = 0
# check if folder exists"
$void = Get-Item $folder -ErrorVariable err -ErrorAction SilentlyContinue
if ($err.Count -ne 0) {
# create when it doesn't
$void = New-Item -Path $folder -ItemType Directory -Force -Verbose
}
$void = Copy-Item -Path $_ -Destination $des -Force -Verbose
#$void = Copy-Item -Path $_ -Include $Criteria -Destination $Path $Choice -Recurse -Container
#$void = Copy-Item -Path $Files -Include $Criteria -Destination $newdes -Force -Verbose -Recurse -ErrorAction SilentlyContinue
Write-Host $_
}
Write-Host $newdes
为什么不使用 -Recurse 开关？
$source = 'C:\source'
$dest = 'C:\dest'
$extensions = @('*.pdf')
Copy-Item -Path $source -Destination $dest -Include $extensions -Force -Recurse
好的，谢谢帮助，我现在已经解决了这个问题，但是又出现了另一个问题。请问post另一个问题
上面的解决方法是使用
-filter "*.pdf"
