Using the "-e --execute" option you can execute mysql/mariadb
commands from the command line, one at a time. You don't have to put
them into a file first. That should allow you to do what you're
after, including doing variable substitution of the password on the
line you want to execute. You can also put the mysql root pw on that
line with substitution so no prompting is involved.
