This being a Linux forum, not an Apple OS X forum, you might be asking the wrong group of folks.
I'm aware that OS X is based on Unix via BSD, but I have no way of knowing how many of the commands are the same as what Linux has in a standard installation.
and see if there is a manual page for the command. If not, you may not have it on your system.
If not, there is also "adduser"
If that doesn't work, try an OS X forum where people are familiar with Apple.
Good luck. With some research, I'm sure you'll learn command line basics for your system.
