Exclude folder and files when using get-childitem in powershell - powershell

Question

I'm not sure how I should be excluding the following:
.env, web.config, node_modules
$sourceRoot = "C:\Users\Wade Aston\Desktop\STEMuli\server"
$destinationRoot = "C:\Users\Wade Aston\Desktop\STEMuli/server-sandbox"
$dir = get-childitem $sourceRoot -Exclude .env, web.config, node_modules <-- How do I exclude these
$i=1
$dir| %{
[int]$percent = $i / $dir.count * 100
Write-Progress -Activity "Copying ... ($percent %)" -status $_ -PercentComplete $percent -verbose
$_ | copy -Destination $destinationRoot -Recurse -Force
$i++
}
Thank you =]

Answer 1

a couple of notes:
* Try using wildcards, to apply exclusion, like: *.env
* Copy-Item parameter Source, allows using collection of type String. Using collection should be faster, than processing sequential with foreach!
* If you need only the files, you may consider using Get-ChildItem -File
You may try something like:
$Source = Get-ChildItem -Path C:\TEMP -Exclude dism.log, *.csv
$dest = 'C:\temp2'
Copy-Item -Path $Source -Destination $dest -Force
Hope it helps!

Answer 2

To exclude both certain files like '*.env' and 'web.config' AND also exclude a folder with a certain name, you could do this:
$sourceRoot = "C:\Users\Wade Aston\Desktop\STEMuli\server"
$destinationRoot = "C:\Users\Wade Aston\Desktop\STEMuli\server-sandbox"
$dir = Get-ChildItem -Path $sourceRoot -Recurse -File -Exclude '*.env', 'web.config' |
Where-Object{ $_.DirectoryName -notmatch 'node_modules' }
$i = 1
$dir | ForEach-Object {
[int]$percent = $i / $dir.count * 100
Write-Progress -Activity "Copying ... ($percent %)" -Status $_ -PercentComplete $percent -Verbose
$target = Join-Path -Path $destinationRoot -ChildPath $_.DirectoryName.Substring($sourceRoot.Length)
# create the target destination folder if it does not already exist
if (!(Test-Path -Path $target -PathType Container)) {
New-Item -Path $target -ItemType Directory | Out-Null
}
$_ | Copy-Item -Destination $target -Force
$i++
}
