27 megabytes of what? Text from mysqldump? Any sort of compression should shrink that fantastically.
Instead of constantly using root to drop entire databases -- might just be the teensiest bit dangerous -- just list tables and delete them as the same user.
Code:
mysql -u username database -b --skip-column-names <<EOF > /tmp/$$-tables
SHOW TABLES
EOF
while read table
do
echo "DROP TABLE $table"
done < /tmp/$$-tables | mysql -u username database
rm -f /tmp/$$-tables
And yeah, you can dump as many tables simultaneously as you want.
I am trying to transpose tables listed in the format into format. Any help would be greatly appreciated.
