Bias Analysis

Detected Bias Types

missing_linux_example

windows_tools

Summary

The documentation page demonstrates a Windows bias by exclusively providing Windows command-line examples (using 'cmd /c' and Windows environment variable syntax), referencing Windows file paths (with backslashes), and omitting any Linux or cross-platform shell examples. There is no mention of Bash, sh, or Linux-specific command lines, nor are there notes about cross-platform compatibility or how to adapt the examples for Linux compute nodes.

Recommendations

Provide parallel Linux/Bash shell examples for all command-line snippets (e.g., use 'bash -c' or 'sh -c' and appropriate environment variable and path syntax).
Explicitly mention that Batch compute nodes can run both Windows and Linux, and clarify any differences in job preparation/release task scripting.
Add a section or callout explaining how to write cross-platform scripts for job preparation and release tasks, including tips for detecting the OS and using portable commands.
Update sample output and file paths to include Linux-style paths (forward slashes) and environment variable syntax ($VAR).
Where Windows tools or patterns are mentioned, provide Linux equivalents (e.g., 'del' vs. 'rm', '%VAR%' vs. '$VAR').
