0. First off: if there is no .cue file, no splitting is possible!
This being said, we can move on:
1. Install these tools:
sudo aptitude install cuetools shntool2. Split the file:
cuebreakpoints large_file.cue | shnsplit -o flac large_file.flac3. Tag the tracks (according to the ripping information present in the .cue file):
cuetag large_file.cue split-track*.flacThis should be it.
