Working from a list of WordPress sites on a shared hosting environment (sites.txt), create a report of the admin email for each. Includes a link to the settings page to update the value.

COUNT=$(wc -l sites.txt)
for SITE in $(cat sites.txt)
do
    cd $SITE
    echo "Working on $SITE ($i of $COUNT)..."
    echo "## $SITE" >> ../admin-email.txt
    url=$(wp option get siteurl)
    postURL="/wp-admin/options-general.php"
    admin_email=$(wp option get admin_email)
    echo "admin email: $admin_email" >> ../admin-email.txt
    echo " if that's not what you want, you can change it here: $url$postURL" >> ../admin-email.txt
