How to find out how many documents live in a single document library

Question

Is there a way with SharePoint online in 2021 and SharePoint 2013, to easily find out how many documents are stored within a single document library? Same kind of question, two different approaches I am assuming.

Answer 1

Server:

$web = Get-SPWeb https://webUrl
$list = $web.Lists['Doc Lib Display Name']
$list.ItemCount

Online:

Connect-PnPOnline https://tenantName.sharepoint.com/sites/siteName
$list = Get-PnPList 'Doc Lib Display Name'
$list.ItemCount

Answer 2

SharePoint 2013: Get Files, Folders Count in a Document Library using PowerShell

$fileCount = 0

$Web = Read-host “Please enter the SPWEB Url”
$WebObject = get-spweb -Identity $Web
#$WebObject.Lists | Select Title

$LibraryObject = $WebObject.Lists[“$Library”]

$itemcount = $LibraryObject.ItemCount

foreach ($folders in $LibraryObject.Folders)
{

$folderCount ++

    foreach ($file in $folder.Files)
    {
        $fileCount ++

        “{0}`t{1}`t{2}” -f $folder.Name, $file.Name, $filesizeinkb   | out-file C:\SpFileExport.csv -Append     
    }
   
}
Write-Host -ForegroundColor Green “Total Item Count ” $itemcount
Write-Host -ForegroundColor Green “Total File Count ” $fileCount
