SharePoint 2007 Powershell - Overwrite documents that require check out

Question

I'm trying to build a PS script for a SharePoint 2007 which will loop through a list of site collections and update files within the 'Style Library' folder.

foreach ($file in $files) {
    $stream = $file.OpenRead()
    $done = $list.RootFolder.SubFolders["FolderName"].Files.Add($file.Name, $stream, $true)
    Write-Host $done.Name "Uploaded" -BackgroundColor Green
}

This loop tries to upload each file to the library but errors with the following message:

Exception calling "Add" with "3" argument(s): "The file "..." is not checked out. You must first check out this document before making changes."

I'm struggling to find a way to programmatically check out documents, upload the new copy and then check that in. Is there any way of working around this?

Answer 1

You can use CheckOut as below

foreach ($file in $files) {
    $file.CheckOut()
    $stream = $file.OpenRead()
    $done = $list.RootFolder.SubFolders["Hertel"].Files.Add($file.Name, $stream, $true)
    Write-Host $done.Name "Uploaded" -BackgroundColor Green
}
