"if I option -T with other options like -s -f"

So, it sounds like the code you initially provided is not the same code as you're actually having a problem with. What is the exact code that you're having a problem with?

There is always the possibility, also, that your problem is related to using the live CD; I know that most things work as they would do on a real OS, but some things don't always work quite the same way (or at all).
