When I do an "ls -l" in a directory such as /etc, it lists down about 300 entries but I can only go back and see about 150 of them because of my limited "buffer size" or whatever that might be called ! Question : What is the variable that controls this, and how can I change that? P.S. I played around and found that this variable "HZ" might be the right one, I don't know, but I couldn't set it properly.
