\item[rm] A command line utility for removing files, links, and empty directories. It works silently, and thus should be used with care. The \textbf{-t} (interactive) option prompts the user to confirm each file that is being deleted. It can remove directories that contain files with the recursive option (\texttt{-r} or \texttt{-R}), but as it works silently and any deleted files cannot be recovered, it is always a good practice to combine these two options. You can specify multiple files (including the directory path if the target file is not in the current directory) and use wildcards like \texttt{?} and \texttt{*}.
