title: Is there a way to dump all mysql databases except for system databases?
body: <p>I use mysqldump to automatically dump all my databases to a text file and save this dump as backup. I use the --all-databases option which dumps my databases, but it also dumps system databases (information_schema, phpmyadmin, etc.) which I don't need.</p>
  
  <p>Is there a way to dump all my databases with mysqldump without naming them explicitly on the command line (so that I don't have to modify the backup script every time I create a new database), but ignore all the system databases?</p>
