Summary:
The documentation exclusively provides Windows-centric examples and command lines (e.g., 'cmd.exe /c echo'), with no mention of Linux shells, tools, or cross-platform patterns. All code snippets use Windows command syntax, and there is no guidance for users running Batch tasks on Linux pools. This may confuse or exclude Linux users and does not demonstrate parity.
Recommendations:
- For every example using 'cmd.exe /c echo', provide a Linux equivalent using '/bin/bash -c echo' or similar.
- Explicitly mention that Azure Batch supports both Windows and Linux pools, and clarify any differences in task command lines or behaviors.
- Add a section or callout explaining how to adapt the .NET examples for Linux-based pools, including common shell differences.
- Where possible, use cross-platform commands or highlight how to write platform-agnostic task commands.
- Ensure that references to tools or shell environments (e.g., cmd.exe) are balanced with Linux equivalents (e.g., bash), and avoid assuming Windows as the default.
