I've tried to find answer, but without any result.
Some commands of bin/console
and ./psh.phar
are without description, so it is difficult to understand their purposes.
Is there a command to delete all demo data from database in Shopware 6?
Try to execute ./psh.phar init
.
As stated in the description, it
Installs database and dependencies with default data set
After that you should have a clean database with default data, but without demo data. Note that this will reset your complete data. There is no command to only delete demo data.
