Well assuming that is the entirety of your Create-SPFoldersBulk.ps1 script then the first issue is that it does currently do anything. Your script defines a function but then doesn't call it.
You're then running the script correctly as :
.\Create-SPFoldersBulk.ps1
and then I'm guessing you're trying to run the function, but that won't work from a command line. That's why you're getting the error, PowerShell doesn't know about the function outside of the code execution, and won't run the script instead since you haven't
added .\ before it.
If you really want it to be using a function then you'll need code later in the script to call that function, eg add the function call you entered at the prompt into the script at the bottom, and then run the script like you did initially, or if you're looking
to be able to run the script and be able to pass those parameters to it from the prompt then you probably want to adjust the script to :
Param (
[parameter(Mandatory=$true)][string]$SiteUrl,
[parameter(Mandatory=$true)][string]$LibraryName,
[parameter(Mandatory=$true)][string]$CSVPath
Add-PSSnapin Microsoft.SharePoint.PowerShell -erroraction SilentlyContinue
# Import CSV
[array]$FolderList = Import-Csv $CSVPath
# Script Variables
$spWeb = Get-SPWeb $SiteUrl
$spList = $spWeb.Lists[$LibraryName]
Foreach ($folderGroup in $FolderList) {
# Create Parent Folder
$parentFolder = $spList.Folders.Add("",[Microsoft.SharePoint.SPFileSystemObjectType]::Folder,$folderGroup.Root)
$parentFolder.Update()
Write-Host "The Parent folder" $folderGroup.Root "was successfully created" -foregroundcolor Green
# Loop variables
$i = 1
$col = "S"
$colID = $col + $i
While ($folderGroup.$colID -ne $null)
$newSubfolder = $splist.Folders.Add($parentFolder.Folder.ServerRelativeUrl, [Microsoft.SharePoint.SPFileSystemObjectType]::Folder,$folderGroup.$colID)
$newSubfolder.Update()
Write-Host "The subfolder" $folderGroup.$ColID "was successfully created" -foregroundcolor Cyan
$i++
$colID = $col + $i
$spWeb.Dispose()
and then call the script from the prompt as :
.\Create-SPFoldersBulk.ps1 -SiteUrl "https://spdev.baordbooks.com/legal/DAP/" -LibraryName "DAP Documents" -CSVPath "C:\Script_Files\folderList.csv"
