Summary

The documentation demonstrates a moderate Windows bias. PowerShell is presented as a primary automation method alongside the Azure CLI, and the prerequisites section provides detailed instructions for installing and using Azure PowerShell, which is a Windows-centric tool. The documentation refers to 'PowerShell' without clarifying cross-platform support, and the CLI examples use the Azure CLI, which is cross-platform, but there is no mention of Bash or Linux-specific shell usage. The order of presentation is mostly Portal, PowerShell, then CLI, which subtly prioritizes Windows tooling. There are no explicit Linux/Bash examples or references to Linux-native tools.

Recommendations

Clarify that Azure PowerShell is available cross-platform, but also provide Bash shell examples where appropriate.
Add explicit Bash/Linux shell examples for CLI commands, including sample shell scripts for automation.
In the prerequisites, mention that Azure CLI and Azure PowerShell are both available on Linux, macOS, and Windows, and provide installation links for all platforms.
Consider alternating the order of PowerShell and CLI examples, or explicitly stating that both are cross-platform.
Where possible, provide guidance for Linux users (e.g., using Bash variables, scripting, or integrating with Linux-native automation tools).
