SharePoint Online management shell : Get-SPOSite

Question

How to check if subsite exist in sharepoint online through SharePoint Online management shell. I can not see any Get-SPOWeb command like Get-SPOSite

Answer 1

I had the same need, so I turned to using CSOM in PowerShell and created this function for our PowerShell module. It does not recurse through the entire site, it just returns the subsites off of the root site collection, but might help you get started anyway.

Function Get-AllSPOWebs{
    <#
        .SYNOPSIS
        Returns an array of subsites below the provided URL. Does not recurse.
        .DESCRIPTION    
        Returns an array of subsites below the provided URL, this is not a recursive function.
        .PARAMETER Url
        The URL of the site to find subsites for.
        .EXAMPLE
        The following would get all the subsites from the Auburn site, then do something with them.
        $subsites = Get-AllSPOWebs -Url "https://tenant.sharepoint.com/sites/site"
        foreach ($site in $subsites){
            #Do something
        }
    #>
    param(
        [Parameter(Mandatory=$true)][string]$Url
    )
    begin{
        $returnWebs = @()
        $context = New-Object Microsoft.SharePoint.Client.ClientContext($Url)
        $context.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($credential.UserName, $credential.Password)
        $rootWeb = $context.Web
        $childWebs = $rootWeb.Webs
        $context.Load($rootWeb)
        $context.Load($childWebs)
        $context.ExecuteQuery()
    }
    process{
        $returnWebs += $rootWeb
        foreach($childWeb in $childWebs){
            $context.Load($childWeb)
            $context.ExecuteQuery()
            $returnWebs += $childWeb
        }
    }
    end{
        return $returnWebs
        $context.Dispose()
    }
}

To get Sites as well as Site groups, please refer to the script below:

Connect-SPOService –url https://site-admin.sharepoint.com


$sites = Get-SPOSite -Detailed

foreach ($site in $sites)
{

    Write-Host $site.Title
    $siteGroups = Get-SPOSiteGroup -Site $site.Url

    foreach ($group in $siteGroups)
        {
              $users = Get-SPOUser -Site $site.Url  -Group $group.Title -Limit All |ft -wrap 
              $url = $site.Url
              $groupName = $group.Title
              Write-Host $groupName + ' ' + $group.Users
          }
}
