I know the nextcloudcmd (https://docs.nextcloud.com/desktop/2.3/advancedusage.html#nextcloud-command-line-client)
But that is not what I am looking for.
I am looking for a linux service which is running via systemd and which syncs changes soon.
This implies that running nextcloudcmd again and again is not a solution.
Starting nextcloudcmd via a simple inotify-script is not really a solution, since this produces a lot of useless IO if the directory is huge and a lot of small changes happen.
The nextcloud desktop client has already solved this.
Is there no way to make this smart algorithm available via a linux systemd service?
