Enable Anonymous Access in SharePoint using PowerShell

In continuation with my last post, How to Enable Anonymous Access in SharePoint 2013, Here are some nifty PowerShell scripts to manage anonymous access in SharePoint:

PowerShell script to Enable Anonymous Access settings of a Web Application:

Add-PSSnapin -Name Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue

$webApp = Get-SPWebApplication 'http://sharepoint.crescent.com/'
$webApp.IisSettings['Default'].AllowAnonymous=$true
$webApp.update()

PowerShell to Set anonymous access on specific SharePoint sites:
$web = Get-SPWeb http://sharepoint.crescent.com/sites/operations
#Enabled -  lists and libraries; On - Entire web site ; Disabled - Self explanatory :-)
$web.AnonymousState = [Microsoft.SharePoint.SPWeb+WebAnonymousState]::Enabled 
$web.Update()

Enable anonymous access on all sites under a web application:
(Get-SPWebApplication http://sharepoint.crescent.com | Get-SPSite | Get-SPWeb | Where {$_ -ne $null -and $_.HasUniqueRoleAssignments -eq $true } ) | ForEach-Object { $_.AnonymousState = [Microsoft.SharePoint.SPWeb+WebAnonymousState]::On; $_.Update(); }

Enable Disable anonymous access at List or library level in SharePoint 2010:
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue

$web = Get-SPWeb http://sharepoint.crescent.com/sites/operations

$list = $web.lists.tryGetList("Documents")
if($list -ne $null)
{
$list.BreakRoleInheritance($true)
$list.AllowEveryoneViewItems = $true
$list.AnonymousPermMask64 ="Open, OpenItems, ViewListItems, ViewVersions, ViewFormPages, ViewPages, UseClientIntegration"
$list.update();
}
To disable anonymous access, You can either set the Permission mask as:
$list.AnonymousPermMask64 ="EmptyMask" or reset inheritance by calling: $list.ResetRoleInheritance()
