Remove sample data modules or update sample data

1. Log in to the Magento server as, or switch to, a user who has permissions to write to the Magento file system. One way to do this is to switch to the Magento file system owner.

   If you use the bash shell, you can also use the following syntax to switch to the Magento file system owner and enter the command at the same time:

   su <Magento file system owner> -s /bin/bash -c <command>
   

   If the Magento file system owner does not allow logins you can do the following:

   sudo -u <Magento file system owner>  <command>
   

2. To run Magento commands from any directory, add <your Magento install dir>/bin to your system PATH.

   Because shells have differing syntax, consult a reference like unix.stackexchange.com.

   bash shell example for CentOS:

   export PATH=$PATH:/var/www/html/magento2/bin
   

Remove sample data modules

Enter the following command:

magento sampledata:remove 

Prepare to update sample data

This command enables you to update sample data before you update the Magento application.

To prepare sample data for updating, enter the following command:

magento sampledata:reset

After that, update the Magento application.
