This PR updates the Bash script to be more robust, maintainable, and readable. It addresses various issues related to input validation, error handling, OS compatibility, and code clarity.

Changelog

• Enhanced error messages and usage instructions for easier troubleshooting.
• Improved script portability with a case structure for OS detection.
• Verified the presence of the movement command before execution.
• Cleaned up formatting, variable quoting, and eliminated unnecessary code elements.

Testing

1. Ran the script without arguments to verify that it prints a clear and immediate usage error.
2. Supplied invalid arguments and confirmed that errors are handled gracefully.
3. Tested on both macOS and Linux systems to ensure sed commands and case structure function correctly.
4. Confirmed that when execute_move=true, the movement command is found and Move scripts run successfully.
5. Checked logs generated by Move script runs to ensure correct logging output.

Outstanding Issues

• No known outstanding issues at this time.
• Future enhancements could include automated testing or additional argument validation.
