Bring the ChristBashTree to PowerShell (with a little help from wsl)

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

christbashtree

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:

Loop over resources and add to terraform state file

Padding a Number with zeros:

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

Use arithmetic evaluation:

A primitive az cli PowerShell wrapper for output parsing and error handling

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:

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

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

function paz {

Get files from Azure file share recursively

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:
