Enhancing Automation: Running Python Scripts with a Shell Script

In the field of software engineering, Python language is highly regarded because of its versatility and extensive libraries making it a vital tool for most developers. But how can we take this effectiveness even further? That’s where Shell scripts come in — they serve as the gatekeepers of automation. By combining Shell scripts with Python you can unlock an streamlined approach, to managing your tasks creating a harmonious symphony that optimizes work processes.

1. Creating the Shell Script

Begin your script with the shebang line:

bash
#!/bin/bash

2. Execute the Python Interpreter for running the script

Run your Python script using:

bash
python3 $PYFILE

This command will invoke the Python interpreter enabling it to interpret and execute your Python code. The $PYFILE acts, as a link to retrieve the name of your Python file from an environment variable and passing it to the interpreter, for execution.

3. Grant Execution Permissions

Ensure your script can be executed with the following command:

bash
chmod +x your_script.sh

4. Setting up the Environment Variable

Assign the Python file name to the $PYFILE variable using this command;

bash
export PYFILE=your_python_script.py

5. How to Run the Script

Execute your script with a single command:

bash
./your_script.sh

Conclusion

By combining both Python and Shell scripts you have the ability to automate tasks enhance efficiency and streamline your coding workflow. This powerful combination of Python and Shell scripts can elevate your software engineering skills.
