Haven't you always wondered how to bring Sergio Lepore's wonderful ChristBASHTree to PowerShell?

For this to work you need:

WSL2 running your favorite linux distribution
A PowerShell session (even 5.1 in the default console host if you feel nostalgic)
A cup of steaming hot mullet wine
The following function:

az storage entity merge --entity PartitionKey=$user RowKey=$user Active="false" --table-name AcademyUser --account-name sajedoxlab8idgyu4918oj

Padding a Number with zeros:

j=12
Academy${(l:3::0:)j}
# ==> Academy012

Use arithmetic evaluation:

Az CLI has many advantages over the Az PowerShell modules, but natively it does not integrate very nicely with PowerShell scripts. That is mainly because of two reasons:

The output of AZ CLI needs to be parsed in order to chain commands together
Exception handling within PowerShell's try-catch clauses is not possible

Both problems can be tackled with a very simple wrapper function:

function paz {

Add the following to your profile:

 how()
 {
        command="${@//[ ]/+}"
        curl cheat.sh/"$command"
        print -S "`curl -s cheat.sh/\"$command?QT\"`"
 }

Imagine you have a policy to not keep files on an azure file share that are older than a specified time, lets say 5 days.

The Az.Storage powershell module provides the cmdlet Get-AzStorageFile that can be used to retrive the files from an Azure file share, but there are two shortcomings of this cmdlet, that makes our task a bit difficult (at least in the module's current version when writing this article: 5.1.0):

Files are not retrieved recursively. If you hit a folder, you need to call Get-AzStorageFile on this folder, if you want to list it's content.
File properties like LastModified are not retrieved. You need to manually call the FetchAttributes() method to fill this attributes with value.

Fortunately PowerShell 7 makes it relatively easy to address both problems with a simple wrapper function:

	[CmdletBinding(SupportsShouldProcess)]
	param (
	# Path to the script with "requires module" statements
	[Parameter(Mandatory)]
	[string]
	$Path
	)

	$dependencies = Get-ChildItem $Path \|
	Select-String -Pattern "^#Requires -Module (@{ ModuleName = '[^']+'; RequiredVersion = '[0-9.]+';? })" \|

	# The assignment is neede to treat the return value of sed as array
	IFS=$'\n' pictures=($(cat /home/mbatsching/git/abtis-cmp/deploy/powerbi/powerbi-update-datasource-credentials.template.html \| grep img \| sed -E 's/.img src="([^"]+)"./\1/g'))
