The Problem: Bash Script Fails to Execute in Python

[[See Video to Reveal this Text or Code Snippet]]

Even with the successful code execution, the expected outcomes in camera functionality never materialize. What gives?

Understanding the Issue

Common Reasons Your Script May Not Execute

Dependent Scripts: Your Bash script may depend on other scripts or files located in the same directory. When invoked through Python, these dependencies may not resolve correctly.

Environment Differences: The environment in which Python is run (such as permissions, paths, etc.) may differ significantly from that of Terminal.

Key Changes Made

Working Directory: The cwd parameter is used to change the execution context to where the Bash script resides, ensuring it can locate any dependent scripts or resources it requires.

Best Practices to Consider

Avoid CWD Dependencies: It's good practice to structure your scripts so they do not depend on the current working directory. This can prevent similar issues in the future.

Error Handling: Always check the return code and examine potential output errors when running scripts to capture any issues.

Testing and Validation: Run scripts directly in the command line to confirm their functionality before integrating them into your Python code.
