If you’re having trouble with your web server timing out before the export is complete, or if you just like terminal better, you may enjoy the command-line tool.
It works just like the plugin, but produces the zipfile on STDOUT:
php jekyll-export-cli.php > jekyll-export.zip
If using this method, you must run first cd into the wordpress-to-jekyll-exporter directory.
Alternatively, if you have WP-CLI installed, you can run:
wp jekyll-export > export.zip
The WP-CLI version will provide greater compatibility for alternate WordPress environments, such as when wp-content isn’t in the usual location.
