There are thousands of commands that are available via Terminal. But, like you, I've seldom used it as it is easy to make a mistake by leaving out a 'space' or using "I" instead of "l" or "1." Or even "-rm" which I think is the command to delete/remove something. I'd suggest reading a book or visiting some sites that instruct one how to use all the power that hides just under the OS. There
are "Man" pages, supposedly pages in a 'manual' describing what a particular command or 'verb' does. Unfortunately, it is written by those who already
know what every thing means and only need/want something to jog their memory.
The rest of us will spend hours finding what a command means on a Man page by looking at another Man page and searching for another word on that page in yet another page, ad infinitum...by which time we have forgot what the original question was.
What you see in Macworld has
usually been proof red more than wonce. OTOH, you may find out
next month that the crash you caused was caused by the editor missing the slightly incorrect printing of the the article.
Many of us simply wait a few months for some one to put a gui face on a 'program' that does nothing more than issue the command line via Terminal with the click of a button. These apps also usually display the results, if any, in a much easier to understand, or at least better looking way than what one gets in Terminal.
My philosophy is; "Just because something
can be done is no reason for
me to do it!"
