Question

I’m busy writing a basic migration scripts for some WP sites, and i’m trying to automate creating mysql database and user credentials from reading the wp-config file

how can i read the following variables from the wp-config file so that i effectively end up with 3 variables within a bash script:

/** The name of the database for WordPress */
define('DB_NAME', 'somedbname');

/** MySQL database username */
define('DB_USER', 'someusername');

/** MySQL database password */
define('DB_PASSWORD', 'somerandompassword');

eg my output should effectively give me:

WPDBNAME=somedbname
WPDBUSER=somedbuser
WPDBPASS=somerandompassword

Try this:

WPDBNAME=`cat wp-config.php | grep DB_NAME | cut -d \' -f 4`
WPDBUSER=`cat wp-config.php | grep DB_USER | cut -d \' -f 4`
WPDBPASS=`cat wp-config.php | grep DB_PASSWORD | cut -d \' -f 4`
