dump all databases

[Xah Lee]

Is there a way to quickly dump all databases into one directory, with files
corresponding to each database?

That is, I wish to do call one single script that:

1. find out what databases are available,
2. for each database, do a mysqldump -d database_name to /home/xah

This probably can be written in few lines of Perl. Ideas? (I guess my
question would be how to get the list of databases.)

Thanks.
