Remove unique permissions on all locations on site SharePoint 2013

Question

I want to remove all unique permissions on one site from all locations on it, whether they are lists, libraries, list items, folders or docs in libraries. All unique permissions must be removed.

I found PS script to delete unique permissions on lists or on site, but that's it, no examples to remove from all locations.

scripts I found are bellow:
for site:

$WebURL ="#"
$web = Get-SPWeb $WebURL
if ( ($web.HasUniqueRoleAssignments) -and ($web.IsRootWeb -eq $false ) )
{
  $web.ResetRoleInheritance()
  Write-host "Broken Inheritance Reset on web:" $web.URL
}

for list:

$WebURL ="#"
$Web = Get-SPWeb $WebURL
$ListColl =  $web.lists | Where-Object
{
  ($_.HasUniqueRoleAssignments -eq $true)  -and ($_.hidden -eq $false)
}
foreach($list in $ListColl) #if($list) #Exists
{
  $list.ResetRoleInheritance()
  Write-host "Broken Inheritance Reset on List:" $list.Title
}

Any help?

Try this

#Variable for Web URL
$WebURL ="Your URL "

# Varibale to hold document count 
$count = 0

#get Web object
$Web = Get-SPWeb $WebURL

if ( ($web.HasUniqueRoleAssignments) -and ($web.IsRootWeb -eq $false ) )
{
  $web.ResetRoleInheritance()
  Write-host "Broken Inheritance Reset on web:" $web.URL
}

#Get Lists with Unique permissions - Exclude Hidden lists
$ListColl =  $web.lists | Where-Object  {  ($_.HasUniqueRoleAssignments -eq $true)  -and ($_.hidden -eq $false) }

#Enumerate through each list and reset permission inheritance
foreach($list in $ListColl) #if($list) #Exists
 {
      #Reset list inheritance
      $list.ResetRoleInheritance()
      Write-host "Broken Inheritance Reset on List:" $list.Title

        foreach ($folder in $list.Folders)
         { 
            if ($folder.HasUniqueRoleAssignments)
            {
              Write-Host "Resetting Folder inheritance at:" $folder.Url  
              $folder.ResetRoleInheritance() 
              $folder.Update()
            }
         }  


#Get all items with unique permissions 
    $itemsWithUniquePermissions = $list.GetItemsWithUniquePermissions() 
    Write-Host $itemsWithUniquePermissions.Count "number of items with unique permissions found." 

    # Only update items if some exist 
    if ($itemsWithUniquePermissions.Count -gt 0) { 
        foreach ($itemInfo in $itemsWithUniquePermissions) { 
            $item = $list.GetItemById($itemInfo.Id) 
                $item.ResetRoleInheritance() 
            $count++ 
        } 

        # Display number of items updated 
        Write-Host "Updated permissions on $count items." -foregroundcolor Green 
    }
 $web.Dispose() 

 }

//We can also delete unique permissions of all list items in a single line as:

(Get-SPweb $WebURL).Lists["$list.Title"].Items | Foreach-Object{ $_.ResetRoleInheritance() }

Hope this wil help you

So, I managed to find a solution for my question.
Bellow is Powershell script code:

Add-PSSnapin microsoft.sharepoint.powershell -ErrorAction SilentlyContinue

#Variable for Web URL
$WebURL ="#"

#get Web object
$Web = Get-SPWeb $WebURL

#Get Lists with Unique permissions - Exclude Hidden lists
$ListColl =  $web.lists | Where-Object  { ($_.hidden -eq $false) }
#Enumerate through each list and reset permission inheritance  
foreach($list in $ListColl)
{
 #Reset list inheritance
 $list.ResetRoleInheritance()
 Write-host "Broken Inheritance Reset on List:" $list.Title

 $items = $list.Items | Where-Object{$_.HasUniqueRoleAssignments};
 foreach($item in $items)
 {
  #Reset broken list item inheritance
  $item.ResetRoleInheritance()
  Write-host "Broken Inheritance Reset on List Item:" $item.URL
 }
 #}
$folders = $list.Folders
if ($folders.Count -gt 0)
{
 foreach ($folder in $folders) 
 {
  if ($folder.HasUniqueRoleAssignments -eq $True)
  {
    $folder.ResetRoleInheritance()
    $folder.update()
  }
 }
}
}

And that's it, this script removes all unique permissions on all docs, items, lists, libraries, folders on one site.

For folders try the following:

$folders = $list.Folders
if ($folders.Count -gt 0)
{
    foreach ($folder in $folders) 
    {
        if ($folder.HasUniqueRoleAssignments -eq $True)
        {
            $folder.ResetRoleInheritance()
            $folder.update()
        }
    }
}

For list items, try the following:

$list_items = $list.Items
if ($list_items.Count -gt 0)
{
    foreach ($list_item in $list_items) 
    {
        if ($list_item.HasUniqueRoleAssignments -eq $True)
        {
            $list_item.ResetRoleInheritance()
            $list_item.update()
        }
    }
}
