# mysqlcrypt.sh
# This shell script will run KMyMoney in a MySql database
# and uses the MySql dump program to maintain a copy of the data.
# Additionally, another copy is written to a backup
# directory before running KMyMoney. These backups will be deleted after a
# user-specified number of days.
# Optionally, these data files may be encrypted.
# For encryption, it is necessary that you have the 'gpg' program installed,
# and have set up a key identified by an email address (which may be a pseudo address).
# See 'man gpg' for more info. The kgpg program will help set up these keys.
# DO NOT forget the password associated with gpg; you will need it to access your data.
# Optionally, the data can be removed from the database after KMyMoney finishes,
# and reloaded next time you run.
# It is assumed that your logon user name has the necessary database permissions.
# Please set the following variables to your requirements
MYDIR=$HOME/money # directory where the encrypted copy is to be held
BUDIR=$MYDIR/backup # directory where the backups should go;
FILE=myfin # name for the encrypted copy
DBNAME=KMyMoney # mysql datbase name
