What is accuracy to safely use CI migration ?

Hi guys!
I use CI migration as I followed its instructions but I don't understand where am wrong as this scenario I get the following issues:

PHP Code:

PHP spark migrate
PHP spark migrate --all/*work fine*/
PHP spark migrate name/*not work*/
PHP spark migrate: refresh/*work fine*/
PHP spark migrate: refresh --all/*not working*/
PHP spark migrate: refresh --single/*refresh all but I want only single?*/ [color=#FF4136]why?[/color]
PHP spark migrate:rollback --all/*roll back all*/
PHP spark migrate:rollback --single/*roll back all but I want single?*/[color=#FF4136]why?[/color]
