nextcloudcmd to sync app support files

[mophilly]

I am using nextcloud for a small set of users. Most of the use cases are typical NextCloud stuff; file sharing, calendar, etc. For this, the NextCloud client is employed as usual. And except for the occasional collision with other file sharing services, it works fine.

I also use it to sync files used for a small custom application. There are files that need to be updated for all users. I define a separate file path for this, away from the normal user path. NextCloud moves files around the user cluster nicely. For this case I could better protect the app (and my sanity) from the user if the URL and paths used for the application were not visible to the user in the UI.

One way to do this is to use nextcloudcmd in a shell script. This works, save for one thing. I haven't found the way to tell nextcloudcmd to only move the files that have changed in the way the standard install does. The best I can do at the moment is move files without regard to mod or touch date. At this point I wonder if the file compare is handled separately from nextcloudcmd, and the component that manages the file compare is served by nextcloudcmd as needed.

I have reviewed the docs and the --help page. The answer has eluded me so far.

I hope someone can offer me some guidance.
