I would like to make more use of the terminal. Is there a command I can use that could list for me all the available command of the Mac OS? I am using Snow Leopard.
You can hold the esc button for a few seconds (or press it or tab twice in succession). That will list everything executable in the path as well as all shell functions.
Also check out this question: Got any tips or tricks for Terminal in Mac OS X?.
This is a good introduction: Introduction to the OS X Unix Command Line.
If you type
apropos .*, you will get a nice list of command and descriptions.
I suggest you to read a command line introduction from Apple: "Command Line Primer"
I came across a site recently that has a good list of commands:
A few very interesting commands listed there that I had never seen before (though not documented only, use
man *commandname* locally if necessary):
Many of the commands listed on the site are not OS X specific, but a few gems in there are, including the above.
