rm = remove
-f = all files whether write protected or not without prompting the user for confirmation or writing a message to the console about the file removal.
-r is recursive, which means to repeatedly remove all files until the base case is the only thing left.
There is a whole directory of files you no longer need on your UNIX system. You do not want to remove them one at a time. Use rm -rf/ to remove them all at once.
