How to do custom file copy in Powershell? - powershell

Question

Below power shell script will copy and replace all the contents from source to destination.
Copy-Item -Path $sourcePath -Destination $installationPath -Recurse -Force
This looks simple. But in my case, I need to implement a custom file copy logic.
Logging everything about files being copied.
Skipping certain set of folders.
Sample script:
[Array]$files=Get-ChildItem ($sourceDirectoryPath) -Recurse | Format-Table Name, Directory, FullName
for($i=0;$i -le $files.Length-1;$i++)
{
. . . . . .
# Build destination path based on the source path.
# Check and create folders if it doesn't exists
# Add if cases to skip certain parts.
Copy-Item -Force $sourcePath -Destination $destinationPath
}
Any ideas on how to achieve this? Any other ideas also will help.
Thanks.

Something like this:
$ErrorActionPreference = "Stop"
Set-StrictMode -Version Latest
$sourceDir = "c:\temp\source"
$targetDir = "c:\temp\target"
$skipFiles = #(
"skip.me",
"and.me"
)
Get-ChildItem -Path $sourceDir -Recurse | ForEach-Object {
# ignore folders
if ($_.PSIsContainer)
{
return
}
# skip this file?
if ($skipFiles -contains $_.Name)
{
Write-Verbose "Skipping '$_.FullName'"
return
}
# create target folder when needed
$path = $_.DirectoryName -replace "^$([RegEx]::Escape($sourceDir))",$targetDir
if (!(Test-Path $path))
{
Write-Verbose "Creating target path '$path'..."
New-Item -Path $path -ItemType Directory
}
# copy the file
Write-Verbose "Copying '$_.FullName' to '$path'..."
Copy-Item $_.FullName $path | Out-Null
}
