Daemon Client (GNU/Linux)

Does there exist a daemon client for Nextcloud?

I know there exists a command line client, but this is an interactive command line client and it’s not what I’m looking for.

I’m looking for a daemon that runs in the background and does the same as the graphical client, like detect changes and syncs continuously.

I want to configure such a client using a configuration file, containing the sync directory and user credentials.

No but there is a feature request (with some workarounds):
