Do some monitoring:

cat << EOF | mongo
db.stats();
db.serverStatus();
show dbs;
EOF

Show the last 10 entries in natural order:

cat << "EOF" | mongo
use your_db;
db.your_collection.find().sort({$natural:1}).limit(10);
EOF

Drop the database cube_development:

cat << EOF | mongo
show dbs;
use cube_development;
db.dropDatabase();
EOF

Here is how change the root password of MySQL on Ubuntu or Debian:

/etc/init.d/mysql stop
mysqld_safe --skip-grant-tables
echo "use mysql; update user set password=PASSWORD('newpass') where User='root'; flush privileges;" | mysql -u root -p
## this doesn't work in 'skip-grant-tables' mode:
#echo "SET PASSWORD FOR 'root' = PASSWORD('newpass');" | mysql -u root -p
/etc/init.d/mysql stop
/etc/init.d/mysql start
