18 Nov 2007 Backup mysql databases into separate files
This bach script makes separate backup files of all the databases in mysql and saves the result in the mysql_backup folder.
#!/bin/bash -v
USERNAME='yourusername'
PASSWORD='yourpassword'
HOSTNAME='yourhostname'
BackupFolder='/backup'
for i in $(echo 'SHOW DATABASES;' | mysql --user $USERNAME -p$PASSWORD -h $HOSTNAME | grep -v '^Database$' ); do
mysqldump --user $USERNAME -p$PASSWORD -h $HOSTNAME --opt $i > $BackupFolder/$i.sql;
done;
Remember to change the -h, -p and -h switch according to your needs and avoid space between -p and the password variable.

07 May 2007 Copying One mySQL database from one machine to another
# mysqldump -h host.com -u root -p password sourceDB | mysql -h host2.com -u username -p password -C targetDB
Interestingly, you don’t actually have be on the ‘source’ machine thanks to mySQL’s -h switch. From the target machine, simply specify the remote host after the -h. This was quite useful for me as my source machine didn’t have mysqldump installed.
