Back up only databases matching PATTERN

mysqldump -eBv `echo "show databases like 'MYSQL_PATTERN'"|mysql -N`> OUTPUTFILE
Sometimes, I just want to back up a single client's databases. Fortunately, all clients have a set prefix to their database names. This makes my life easy! I just use 'CLIENTNAME_%' as my MYSQL_PATTERN in this command, and my life is suddenly easy. mysqldump params: -e - (optional) use extended insert. -B - what follows is a list of databases -v - (optional) give verbose output mysql params: -N - don't write column names in output (prevents us trying to back up a database called "Database").
