Execute Python with Shebang - Make Your Scripts Executable
- The shebang line in a Python script allows it to be run as an executable command-line tool without needing to prefix it with 'python'.
- It consists of #! followed by the interpreter path, such as #!/usr/bin/env python3.
- Using '/usr/bin/env python3' makes the script more portable and environment-friendly as it searches for python3 in the user's current $PATH.
- To make a Python script executable, add the shebang line, give it execute permissions using 'chmod +x', and run it directly from the terminal.
- Moving the script to a directory in the $PATH allows it to be run from any location in the terminal.
- File extensions like .py become optional once the script has a shebang line and executable permissions.
- For scripts relying on virtual environments, the shebang can point directly to the virtual environment's Python interpreter path.
- By following these steps, Python scripts can behave like native Unix commands, becoming cleaner and more professional.
- The shebang line enhances script portability and usability, making them easier to share and run across different systems.
- Using #!/usr/bin/env python3 and making scripts executable are key practices for creating effective command-line utilities.
