Summary
The documentation provides extensive Azure PowerShell examples and guidance, which is a Windows-centric toolset, and references PowerShell-specific installation and usage patterns. PowerShell is presented before Azure CLI in both prerequisites and procedural sections, and there is no mention of native Linux shell scripting or Linux-specific nuances. While Azure CLI is cross-platform, the documentation's structure and emphasis favor Windows/PowerShell users.
Recommendations
  • Present Azure CLI examples before PowerShell examples, as CLI is more universally available across platforms.
  • Explicitly mention that Azure CLI commands work natively on Linux, macOS, and Windows, and provide any Linux-specific notes if needed.
  • Add Bash script examples for common tasks, especially in sections where PowerShell scripting is demonstrated.
  • Avoid assuming PowerShell as the default scripting environment; clarify that both PowerShell and CLI are supported and highlight cross-platform compatibility.
  • Where PowerShell installation is discussed, provide equivalent instructions for Bash/CLI environments on Linux and macOS.
  • Consider adding a short section or callout for Linux/macOS users, summarizing the parity and any differences.
