Hi,
I need to create a script to add user as Group Admin in Nextcloud. I’ve done only this, but i don’t know how to put new user in a group admin.

#!/bin/sh
#./occ.sh
sudo -u www-data /usr/bin/php /var/www/nextcloud/occ  $@

./occ.sh group:adduser groupname username

Can anyone help me with that?

Regards
