Laravel Too many arguments, expected arguments "command" while scheduling
I found a solution,
/opt/php70/bin/php /home/sitename/public_html/artisan schedule:run >/dev/null 2>&1
initially i had 1 after schedule:run method . As below
/opt/php70/bin/php /home/sitename/public_html/artisan schedule:run 1 >/dev/null 2>&1
Your code all looks good.Have you tried simply as below
php artisan schedule:run
after reaching at your root folder path.
