This is a bash script template that includes best practices for error handling, input validation, and logging. The template provides a starting point for creating well-structured and maintainable bash scripts.
The script includes a function for handling errors and logging them to a log file. This function is triggered by a trap statement that captures any errors that occur within the script. The function logs the error message and exits the script with a non-zero status, indicating that an error has occurred.
The script includes a function for validating input parameters. The function performs any necessary checks on the input and returns a status code indicating whether the input is valid or not. If the input is invalid, the script calls the error handling function to log the error and exit the script.
The script logs important information to a log file, including the start and end of the script, as well as any errors that occur. This information can be used for debugging and auditing purposes.
To use the template, simply copy the code into a new script file and customize it to fit your specific needs and requirements. The template provides a solid foundation for writing bash scripts that are well-structured and maintainable.
