WebP Converter Bash Script

Overview

This script automates the conversion of image files (JPEG and PNG) to WebP format. It provides features such as creating debug files, logging execution details, and maintaining a clean log directory. You can use it for any CMS or E-commerce like WordPress, Drupal, Joomla, Magento, Prestashop, Opencart etc. It's recursively generating the missing WebP files of the specific folder.

Features

• WebP Conversion: Converts JPEG and PNG files to WebP format.
• Logging: Generates detailed debug files with execution information.
• Dynamic Settings: Reads configuration from a config.txt file.
• Cleanup: Automatically deletes old debug files based on a specified interval.

Usage

1. Clone the Repository:

   git clone https://github.com/erenaksoy/webp-converter.git
   cd webp-converter

2. Configuration:

   • Edit config.txt to adjust settings like log_dir, debug_interval_hours, and other parameters. Don't forget to replace directory to the your actual path.

3. Execution:

   • Run the script: bash webp.sh

4. Logs:

   • Debug files are stored in the specified log directory.

Running with Cron Job

To automate the script execution, you can set up a cron job. For example, to run the script every day at 2:00 AM, add the following entry to your crontab:

1. Open the crontab file for editing:

crontab -e

2. Add a line to schedule the script. For example, to run daily at 2 AM:

0 2 * * * /path/to/webp.sh

Replace /path/to/your/webp.sh with the actual path to the script.

3. Save and exit the text editor.

Debug Files

Debug files are generated in the specified log directory. Each file includes information about the script's execution, converted files, and errors.

Note on Duplicate Skipping

The script checks for already converted WebP files and skips them to avoid duplication. If you need to re-generate all WebP files, set the generateall variable to 1 in the script.

generateall=1 # Re-generate all webp files
