start the mysql service and run commands

[jacek]

But how about if my programm asked for a su password from the user and the execute the command as a root?

That's what "use su" means.

Yes but the question is not what su means. The question is if i can run a command as a su (and hence root).

I ment to say that if it is possible for a user to enter the su/root password and then run a command as a su/root user from my program
