less is a replacement for more. If it's not installed, you will need to install it. It's open source, so you can download and compile it yourself; but if you are not familiar with basic Unix developer tools, it's probably easier to get it from your vendor. How and what exactly depends on your platform. For RPM-based Linux, try rpmsearch. For Debian and Ubuntu, apt-get install less. For big-iron "real" Unix, contact your local system administrator. You most likely need root access to install packages system-wide, but there may also be an option to install for your private use.
