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"/"}'

Pull All Other JSON

rsync -avz --size-only --delete www.iterativechaos.com:/opt/cypherpunk/data/reddit/json/link_list/ /opt/cypherpunk/data/reddit/json/link_list/
rsync -avz --size-only --delete www.iterativechaos.com:/opt/cypherpunk/data/reddit/json/archive_link_list/ /opt/cypherpunk/data/reddit/json/archive_link_list/
