# a small shell script for automatic ordering of TV channels in MythTV
|
||||||
|
#
|
||||||
|
# BIG FAT WARNING: this script was tested only with MythTV v0.23.
|
||||||
|
# Future versions of mythtv possibly use an incompatible database layout.
|
||||||
|
#
|
||||||
|
# The following workflow is recommended:
|
||||||
|
# 1) backup the current channel settings:
|
||||||
|
# ./channel_sort_mythtv.sh dump >mythtv_channels_dump.sql
|
||||||
|
# 2) retrieve the current list of channel names
|
||||||
|
# ./channel_sort_mythtv.sh get >channels.list
|
||||||
|
# 3) sort the channels in 'channels.list' with your favourite text editor
|
||||||
|
# 4) upload the new channel order (starting from channum=1):
|
||||||
|
# ./channel_sort_mythtv.sh set <channel.list
|
||||||
|
#
|
||||||
|
# After another channel scan you can run this script again with the
|
||||||
|
# 'merge' argument. It reads your current channel order from stdin
|
||||||
|
# and appends all 'new' channels (taken from the database).
