\paragraph{Review:}


\begin{enumerate}
\item A directory entry contains:
  \begin{enumerate}
  \item filename and mapping of file contents (data sectors)
  \item filename and inode number
  \item only the inode number and a pointer to the file contents
  \item A symbolic link to the actual filename and file contents
  \item At least: filename, modification, access and change timestamps,
    permissions, size, owner
  \end{enumerate}

\item A system administrator executes the command
\par\vspace*{-0.9\baselineskip}\par
\begin{alltt}
$ \textbf{ls -i *}
54903110 file1  54903109 file2
54903109 file3  54903111 \bl{file4}
\end{alltt}%$
  \begin{enumerate}
  \item \texttt{file1}, \texttt{file2} are hard links to the same
    file, \texttt{file4} is a symbolic link to \texttt{file1}
  \item \texttt{file2}, \texttt{file3} are hard links to the same
    file, \texttt{file4} is a symbolic link to \texttt{file1}
  \item \texttt{file1}, \texttt{file2} are hard links to the same
    file, \texttt{file4} is a dangling symbolic link
  \item \texttt{file1} is not a hard link to any of the other files
  \item \texttt{file2} is a copy of \texttt{file3}
  \end{enumerate}

\item To delete the last three directories in the pathname
  \path{/tmp/a/b/c}, you can do:
  \begin{enumerate}
  \item
\begin{alltt}
$ \textbf{rm -rf /tmp/a}
\end{alltt}%$
\item
\begin{alltt}
$ \textbf{cd /tmp;rmdir -p a/b/c}
\end{alltt}%$
\item
\begin{alltt}
$ \textbf{rmdir /tmp/a/b/c /tmp/a/b /tmp/a}
\end{alltt}%$
\item
\begin{alltt}\small
$ \textbf{rm -f /tmp/a/b/c;rm -f /tmp/a/b;rm -f /tmp/a}
\end{alltt}%$
\item All the other options
  \end{enumerate}
\end{enumerate}

\paragraph{Preparation:}

\begin{enumerate}
\setcounter{enumi}{3}
\item The \texttt{chmod} command is used to:
  \begin{enumerate}
  \item Change the \emph{user} ownership of a file
  \item Change the \emph{group} ownership of a file
  \item Change the \emph{access rights} of a file
  \item Change the \emph{link status} of a file
  \item Convert files to directories and directories to files
  \end{enumerate}

\item The \texttt{mount} command is:
  \begin{enumerate}
  \item used to make a filesystem available at a directory
  \item related to the file \texttt{/etc/fstab}
  \item able to make network file systems (\NFS) available locally
  \item able to make Microsoft Windows shares available locally
  \item All the other options
  \end{enumerate}
\end{enumerate}
