function Copy-AxiumFiles { <# .SYNOPSIS Used to copy axiUm files. Usually run as a startup or logon script. .DESCRIPTION Used to copy axiUm files. Usually run as a startup or logon script. Can be limited to only copy files when connected to a given network, not connected to a given network, or both. This is useful to copy files when connected to your organization's network, but not through on offsite VPN connection which may potentially be slow. Uses RoboCopy under the hood, so it requires RoboCopy to be located in the path, which is the case by default in Windows Vista and latter. RoboCopy will log to "$ClientPath\Copy-AxiumFiles.log". Aliases: cpaf .INPUTS System.String .EXAMPLE PS> 'C:\axiUm' | Copy-AxiumFiles -SourcePathOrPrefix $PSScriptRoot Copies the files for a single instance of axiUm from the directory this script is in to "C:\axiUm", writing a log file to "C:\axiUm\Copy-AxiumFiles.log". Only new and updated files are copied, and the IP addresses of the device are not considered. .EXAMPLE PS> 'C:\axiUm' | Copy-AxiumFiles -SourcePathOrPrefix $PSScriptRoot -CopyAll Same as Example 1, but copies all files. .EXAMPLE PS> 'C:\axiUm' | Copy-AxiumFiles -SourcePathOrPrefix $PSScriptRoot -RequireInSubnet @('10.0.0.0', '255.0.0.0') -RequireNotInSubnet @('10.2.0.0', '255.255.0.0) Let us say that your organization has IP addresses in 10.0.0.0/255.0.0.0, but your VPN uses a small part of that (10.1.0.0/255.255.0.0). This would do the same as Example 1, but only if the workstation this was run on was connected to your organization's network, but not through VPN. This is useful if you want to push out a lot of files, but are worried about doing this when somebody is connected via a slow offsite wifi connection to your VPN. This would skip those workstations, which you could then handle manually. .EXAMPLE PS> 'C:\axiUm' | Get-ChildItem -Directory | Copy-AxiumFiles -SourcePathOrPrefix '\\domain\axiUm-ClientFiles-' -MultipleCopies This is an example of using the MultipleCopies switch to copy files for multiple copies of axiUm. Let us assume there are two installations of axiUm on the workstation this is being run on: * "C:\axiUm\Production" * "C:\axiUm\Test" This will: * Copy all files that are not in or newer than the ones in "C:\axiUm\Production" from "\\domain\axiUm-ClientFiles-Production" to "C:\axiUm\Production". * Copy all files that are not in or newer than the ones in "C:\axiUm\Test" from "\\domain\axiUm-ClientFiles-Test" to "C:\axiUm\Test". .NOTES Author : Dan Thompson Copyright : 2020 Case Western Reserve University #> [CmdletBinding(SupportsShouldProcess)] param( # Where axiUm is installed. # # Aliases: clp [Parameter( Position = 0, ValueFromPipeline = $True, ValueFromPipelineByPropertyName = $True, Mandatory = $True )] [ValidateNotNullOrEmpty()] [ValidateScript({ $_ | Test-Path -PathType 'Container' })] [Alias('clp')] [string]$ClientPath, # If MultipleCopies is set, the name of the last folder in ClientPath will be appended to # SourcePathOrPrefix to get where to copy files from.
