cms_xyz
pqr

In the example given above, I will like to drop all

Answer 1

Linux way:

#!/bin/bash

DB_STARTS_WITH="cms"
MUSER="root"
MPWD="yourpass"
MYSQL="mysql"

DBS="$($MYSQL -u$MUSER -p$MPWD -Bse 'show databases')"
for db in $DBS; do

if [[ "$db" =~ "^${DB_STARTS_WITH}" ]]; then
    echo "Deleting $db"
    $MYSQL -u$MUSER -p$MPWD -Bse "drop database $db"
fi

done

Of course use the drop part at your own risk ;)
