Excluding multiple folders when copying using powershell

问题

The objective is to copy folders and files from a path to another path using PowerShell. However, I want to exclude certain files and folders from getting copied. I was able to exclude multiple files by adding them to the exclude list

Get-ChildItem -Path $source -Recurse -Exclude "web.config","body.css","Thumbs.db"

For excluding folders I added

$directory = @("Bin")
?{$_.fullname -notmatch $directory}

and the final copy script looks like

Get-ChildItem -Path $source -Recurse -Exclude "Web.config","body.css","Thumbs.db" | ?{$_.fullname -notmatch $directory} | Copy-Item -Force -Destination {if ($_.GetType() -eq [System.IO.FileInfo]) {Join-Path $dest $_.FullName.Substring($source.length)} else {Join-Path $dest $_.Parent.FullName.Substring($source.length)}}

This seems to work with a single folder, but when I add multiple folders to the excluded directories it does not seem to work.What can be done to exclude multiple folders?

回答1:

$source = 'source path'
$dest = 'destination path' 
[string[]]$Excludes = @('file1','file2','folder1','folder2')
$files =  Get-ChildItem -Path $source -Exclude $Excludes | %{ 
$allowed = $true
foreach ($exclude in $Excludes) { 
    if ((Split-Path $_.FullName -Parent) -match $exclude) { 
        $allowed = $false
        break
    }
}
if ($allowed) {
    $_.FullName
}
}
copy-item $source $dest -force -recurse

The above code excludes multiple folders listed in $Excludes array and copy the remaining contents to the destination folder

Try this:

$excluded = @("Web.config", "body.css","Thumbs.db")
Get-ChildItem -Path $source -Recurse -Exclude $excluded

From the comment, in case you want to exclude folders, you can use something like this:

Get-ChildItem -Path $source -Directory -Recurse  | 
      ? { $_.FullName -inotmatch 'foldername' }

OR you can check the container first then do this:

Get-ChildItem -Path $source -Recurse  | 
      ? { $_.PsIsContainer -and $_.FullName -notmatch 'foldername' }

回答3:

Because $directory is an array, you should be looking to match its contents and not itself (it is annoying that powershell lets single-element arrays be treated like their contents).

You can try:

?{$directory -contains $_.fullname}

Instead of:

?{$_.fullname -notmatch $directory}
