\paragraph{Review:}


\begin{enumerate}
\item Which of the following commands can list all files in
  \path{/etc} and below, showing their types?
  \begin{enumerate}
  \item
\begin{alltt}
$ \texttt{find /etc | file}
\end{alltt}%$
\item 
\begin{alltt}
$ \texttt{file /etc/* | find -type}
\end{alltt}%$
\item 
\begin{alltt}
$ \texttt{find /etc | xargs file}
\end{alltt}%$
\item 
\begin{alltt}
$ \texttt{file --replace -exec find /etc}
\end{alltt}%$
  \end{enumerate}

\item Select one fact about the \texttt{cpio} and/or \texttt{tar}
  commands:
  \begin{enumerate}
  \item Both can create an archive of files
  \item \RPM{}s are just \texttt{tar} files
  \item \texttt{tar} must always read filenames from standard input
  \item \texttt{cpio} is more widely used than \texttt{tar}
  \end{enumerate}

\item The command: \texttt{ldd /bin/bash} shows:
  \begin{enumerate}
  \item 
\begin{alltt}
        not a dynamic executable      
\end{alltt}
\item shared libraries that \texttt{/bin/bash} is linked to
\item no output
\item an error message
  \end{enumerate}

%% Explain why you might use \texttt{tar} and when you might use
%%   \texttt{cpio}.  State \emph{TWO} applications of each.
%% \item Why might you use \texttt{xargs}?
%% \item State \emph{ONE} reason each  for using \texttt{top},
%%   \texttt{vmstat} and \texttt{ldd}.
\end{enumerate}

\begin{enumerate}
\setcounter{enumi}{3}
\item Common filesystem types on Linux include:
  \begin{enumerate}
  \item cdfilesys
  \item apache
  \item ext3
  \item bash
  \end{enumerate}

\item An \emph{absolute filename} always begins with:
  \begin{enumerate}
  \item a dot: ``\texttt{.}''
  \item a slash: ``\texttt{/}''
  \item a double dot: ``\texttt{..}''
  \item a tilde: ``$\sim$''
  \end{enumerate}
