what's rm -rf / stands for?

rm = remove

-r = recursively

-f = force

If you open a terminal window on a Mac, you can use those commands to delete files.  You can also type "man rm" (without the quotes) in a terminal window for more details on the 'rm' command

In the interest of preventing someone a big heartache I feel like i should chime in here and let it be known that it would be a really, really bad idea run the "rm -rf" command with the root of the file system "/" as an argument: that would unlink your entire filesystem.  In other words erase all your files on your mac.  Don't do it. :)
