I just find a very useful site which contains a list of MAC OSX command line. Check out [

Command Line Interface
Terminal is a useful utility, which allows advanced users to work with command line interface (CLI). A lot of programmers prefer this mode due to its flexibility to customize things.
Even for semi-advanced users, Terminal looks scary. One of the problems is that you don't know the command name and their syntax. Documentation is long and some time hard to read. But for sure, it require a lot of effort to comb through the documentation to get what you do using CLI. So a lot of users just give up using CLI.
