Sync
Pull Discussions
This has to be done separately because the remote harvester host will not have the full discussion archive. Remote will have the current and previous month, which can be pulled with --delete.
cd /opt/cypherpunk/data/reddit/json
find discussion -name '2023-09' -type d | awk '{print "rsync -avz --size-only --delete www.iterativechaos.com:/opt/cypherpunk/data/reddit/json/"$1"/ ./"$1"/"}'
