BASH script to change the Security Keys and SALTs in a wp-config.php file

I wanted to automatically change the Security Keys/SALTS when provisioning a new WordPress site. WordPress.com has a service that spits back random values. (https://api.wordpress.org/secret-key/1.1/salt/). The script below CURLs the values and then modifies a wp-config.php file with the new random values.

SALTS=$(curl -s https://api.wordpress.org/secret-key/1.1/salt/)
while read -r SALT; do
SEARCH="define('$(echo "$SALT" | cut -d "'" -f 2)"
REPLACE=$(echo "$SALT" | cut -d "'" -f 4)
echo "... $SEARCH ... $SEARCH ..."
sed -i "/^$SEARCH/s/put your unique phrase here/$(echo $REPLACE | sed -e 's/\\/\\\\/g' -e 's/\//\\\//g' -e 's/&/\\\&/g')/" /Path/To/Your/wp-config.php
done <<< "$SALTS"

Don’t remember where I got the pieces of this, but here it is, I have been using it for a while and it seems to work well.
Hope that helps someone.
