Summary

The documentation provides both Azure CLI and PowerShell examples, but the PowerShell section is prominent and detailed, reflecting a Windows-centric approach. PowerShell is a Windows-native tool (though now cross-platform), and its inclusion before any Linux shell scripting or bash alternatives may signal a Windows-first bias. There are no bash or Linux shell script examples, and no mention of Linux-specific tools or considerations. The CLI examples are cross-platform, but the documentation does not explicitly highlight Linux usage or parity.

Recommendations

Add bash or Linux shell script examples alongside PowerShell, especially for automation scenarios.
Explicitly mention that Azure CLI commands work on Linux, macOS, and Windows, and provide sample terminal prompts (e.g., $ for bash, PS> for PowerShell) to clarify context.
If PowerShell is included, consider also including bash equivalents for common tasks, or at least reference that PowerShell is available cross-platform.
In sections where PowerShell is used, add a note or link to guidance for using Azure CLI or bash on Linux.
Ensure that any references to tools or scripting environments are balanced between Windows and Linux, or clarify their cross-platform support.

> [!NOTE]
> If you specify a queue or topic by using the `--forward-dead-lettered-messages-to` parameter, Service Bus automatically forwards dead-lettered messages to that queue or topic. Here's an example: `az servicebus queue create --resource-group mysbusrg --namespace-name mysbusns --name myqueue --enable-dead-lettering-on-message-expiration true --forward-dead-lettered-messages-to myqueue2`.

## Using Azure PowerShell
To **create a queue with dead lettering on message expiration enabled**, use the [`New-AzServiceBusQueue`](/powershell/module/az.servicebus/new-azservicebusqueue) command with `-DeadLetteringOnMessageExpiration` set to `$True`.

To **enable the dead lettering on message expiration setting for an existing queue**, use the [`Set-AzServiceBusQueue`](/powershell/module/az.servicebus/set-azservicebusqueue) command as shown in the following example.
