# This script is intended to be called automatically every day (e.g. via cron).
|
|
# It only output stuff if new ranks have to be inserted. Therefore the output
|
|
# may be redirected to email notifying about manual action to transfer the
|
|
# ranks to MySQL.
|

#
|
|
# Configure cron as the user running the DDNet-Server processes

|

# $ crontab -e

# 30 5 * * * /path/to/this/script/move_sqlite.py --from /path/to/ddnet-server.sqlite
|
|
#
|
|
# Afterwards configure a MTA (e.g. postfix) and the users email address.
