You're not passing the 'hellow*' argument to grep. The 'hellow*' is first expaned by your shell, so it probably turns that command line into 'lsmod | grep helloworld.c helloworld.o helloworld.ko'. Try using 'lsmod | grep hellow' instead (i.e. without the *). > sunil@ubuntu:~/test/drive$ modprobe -r helloworld > FATAL: Module helloworld not found. Obviously, because your previous command succeeded. The module is no longer loaded. Regards, Kristof PS: Please don't top-post.
