hi dear experts, I've found the cause of my problem. It is just a stupid error. I was using Yakuake Terminal Program, which supports only tsh. I have only recognized it now and changed to bash to execute "source ~/.bashrc". Besides, I have also forgotten to change the name of the path in bashrc file, according to ns-allinone-2.32.
Now there is no problem any more. B.
