startMysql.sh

# /bin/sh

# If there is a MySQL configuration file present in the MAMP conf directory,
# use it as the only configuration file processed by MySQL.  Otherwise use the
# sequence of MySQL configuration files as defined in the MySQL documentation: 
# 
#   http://dev.mysql.com/doc/refman/5.5/en/option-files.html
