Summary:
The documentation page exhibits a strong Windows bias. All code examples use Windows command-line syntax (cmd.exe /c echo ...), and there are no Linux or cross-platform shell examples. The documentation refers exclusively to Windows tools (cmd.exe), and does not mention Linux shells (bash/sh) or provide equivalent Linux command examples. The structure and examples assume a Windows environment by default, with no guidance for Linux users.
Recommendations:
- For every code example using Windows command-line (cmd.exe), provide an equivalent Linux shell (bash/sh) example, e.g., 'bash -c "echo Flowers"'.
- Explicitly mention that Azure Batch supports both Windows and Linux compute nodes, and clarify any differences in task command line syntax.
- Add a section or note explaining how to adapt the examples for Linux pools, including differences in shell invocation and exit code handling if applicable.
- Avoid using Windows tools exclusively in examples; use cross-platform commands where possible (e.g., 'echo' is available on both platforms, but the shell invocation differs).
- Where possible, provide side-by-side or tabbed code samples for Windows and Linux to improve parity and accessibility for all users.
