Check If Document Library Already Exists Using Powershell

Question

How can I perform a check if a document library already exists using Powershell in SharePoint 2010?

Answer 1

Something like this:

$w = get-spweb "<webURL>"
$list = $w.Lists.TryGetList("<Title of the list>")
if($list -ne $null)
{
    # The list already exists
}

Replace <webURL> and <Title of the list> with your actual values
