Sync NextCloud Files on the Command Line

nextCloud and ownCloud having the same codebase, you can use the nextCloud command line client.

Fetch the owncloud repository key:

wget -nv -O Release.key

Add the owncloud repository key:

apt-key add Release.key

Remove the key file:

rm Release.key

Add the ownCloud repository to your sources:

echo 'deb /' > /etc/apt/sources.list.d/owncloud.list

Add https as a possible transport for packages:

apt-get install apt-transport-https

Update your package data:

apt-get update

Now, install the command line client:

apt-get install owncloud-client-cmd

As of writing, there is a known issue with running in command line mode for the first time when required files don’t exist. See Debian bug report #900287.

The workaround is to manually create the files (be mindful to do this as root for /etc/ and your require user for ~/):

mkdir -p /etc/owncloud-client/

touch /etc/owncloud-client/sync-exclude.lst

mkdir -p ~/.local/share/data/ownCloud/

Now we can add a crontab entry to automatically sync at an interval, since the command line client does not detect changes automatically like the GUI client does:

crontab -e

This assumes you already have a nextCloud running somewhere and a local directory where you want to mirror the content.
