powershell-hashcopy's Issues

Source Path Enhancement

function Get-DestinationFilePath {
    <#
        .SYNOPSIS
            Accepts a source and destination file paths and a file (that from the source path) and returns the equivalent destination path (regardless of whether it exists).

        .PARAMETER File
            The file to modify.

        .PARAMETER Source
            The source directory or file path.

        .PARAMETER Destination
            The destination path.

        .EXAMPLE
            Get-DestinationFilePath -File (Get-ChildItem c:\temp\somefile.txt) -Source c:\temp -Destination d:\example
    #>
    [cmdletbinding()]
    param(
        [Parameter(Mandatory)]
        [System.IO.FileInfo]
        $File,

        [Parameter(Mandatory)]
        [String]
        $Source,

        [Parameter(Mandatory)]
        [String]
        $Destination
    )
    
    if (Test-Path -Path $Source -PathType leaf) {
        $Source = Join-Path (Split-Path -Parent $Source) -ChildPath '/'
    }

    $DestFile = Join-Path (Split-Path -Parent $File) -ChildPath '/'
    $DestFile = $DestFile -Replace "^$([Regex]::Escape((Convert-Path $Source)))", $Destination
    $DestFile = Join-Path -Path $DestFile -ChildPath (Split-Path -Leaf $File)

    Return $DestFile
}

Making the change above allows for the main Copy-FileHash function to accept an array of file paths rather than just directory paths. E.g.:

    # files to copy
    $SourceFiles = @()
    $SourceFilesFilter = @("*.ZIP")
    $SourceDirectories = @($DATSourceDirectory)

    $SourceDirectories | ForEach-Object {
        $SourceFiles += (Get-ChildItem -Path $_ -Recurse -Include $SourceFilesFilter -File).FullName
    }

    # copy files from source to temp
    Copy-FileHash -Path $SourceFiles -Destination $DATTempDirectory

-Mirror parameter doesn't work properly

Hey, this module is really awesome! However, the -Mirror parameter doesn't work correctly for me - it deletes all of the files I want to copy across for some reason. A way to reproduce it is:

1. Copy a directory without the -Mirror switch
2. Copy the same directory with the -Mirror and the -WhatIf switches - it will tell you that it's going to delete all the files

EDIT: After a bit more checking:
Not working: Copy-FileHash -Path C:\somePath -Destination C:\someOtherPath
Working: Copy-FileHash -Path C:\somePath\ -Destination C:\someOtherPath\

Old files are not removed in the destination folder

Hi,

I am using Copy-FileHash to copy files from source folder to destination folder.
However when the the destination folder already contain files that do not exist in the source folder, these files are not deleted.

I want to make sure that by the end of operation, both source and destination contain the same total number of files.
Can I achieve this this using Copy-FileHash without first clearing the destination folder?

Thanks.

Improvements

• Look at using resolve-path instead of new-item to get the full path of the parameters.
• Look at using split-path and join-path when determining the dest path (currently via regex) as this is likely less error-prone plus would likely make the cmdlet cross-platform compatible (e.g at the moment we hard code a backslash where on Linux this would likely fail?).

Mirror two directories by removing files in destination that are not in source

From PaulBrand:

Hello, Mark! Your module is almost PERFECT for what I need to do--I'm pretty geeked to have found it.

One question: is it possible to have HashCopy completely mirror two directories? In other words, can it remove files from the destination that have been removed from the source?

Thank you!
