A WP-CLI command to rename WordPress' table prefix. This is based on Ian Dunn's wp-cli-rename-db-prefix and was create to prevent less confusion when trying to modify the default "$table_prefix" value in the sample wp-config.php file of a new wordpress installation.
wp package install spxis/wp-cli-rename-table-prefix
wp rename-table-prefix <new_prefix>
You will be prompted for confirmation before the command makes any changes.
Use this at your own risk. If something goes wrong, it could break your site. Before running this, make sure to back up your wp-config.php file and run wp db export.
A lot of the code is based on iThemes Security.
