# Backup each mysql databases into a different file, rather than one big file
# Optionally files can be gzipped (dbname.gz)
#
# Usage: dump_all_databases [ -u username -o output_dir -z ]
#
# -u username to connect mysql server
# -o [output_dir] optional the output directory where to put the files
# -z gzip enabled
#
# Note: The script will prompt for a password, you cannot specify it as command line argument for security reasons
#
# based on the solution from: sonia 16-nov-05 (http://soniahamilton.wordpress.com/2005/11/16/backup-multiple-databases-into-separate-files/)
