+\frametitle{Objectives}
+\label{sec-2}
+
+At the end of this tutorial, you will be able to,
+\begin{itemize}
+\item Search for files in various ways
+\item Compare files with same names
+\item Create and extract an archive
+\item Customize a shell
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{Pre-requisites}
+\label{sec-3}
+
+Spoken tutorial on,
+\begin{itemize}
+\item Getting started with Linux
+\item Basic File Handling
+\end{itemize}
+\end{frame}
+
+\begin{frame}[fragile]
+  \frametitle{\texttt{`find'}}
+  \begin{itemize}
+  \item `find' command helps to find files in a directory hierarchy
+  \item Offers a very complex feature set\\ For eg: search files by name, owner, date,etc.
+  \item Look at the \texttt{man} page of `find' 
+  \end{itemize}
+\end{frame}
+
+\begin{frame}[fragile]
+  \frametitle{\texttt{`cmp'}}
+  \begin{lstlisting}
+   $ find . -name quick.c
+   ./Desktop/programs/quick.c
+   ./c-folder/quick.c
+   $ cmp Desktop/programs/quick.c 
+     c-folder/quick.c
+  \end{lstlisting} % $
+  \begin{itemize}
+  \item No output when files are exactly same
+  \item Else, gives location where the first difference occurs 
+  \end{itemize}
+\end{frame}
+
+\begin{frame}[fragile]
+  \frametitle{\texttt{`diff'}}
+  \begin{itemize}
+  \item We know the files are different, but want exact differences i.e. line by line
+  \end{itemize}
+\hspace{30pt}\verb~$diff Desktop/programs/quick.c ~\\
+\hspace{40pt}\verb~c-folder/quick.c~
+ 
+  \begin{itemize}
+  \item \texttt{>} indicates content only in second file
+  \item \texttt{<} indicates content only in first file
+  \end{itemize}
+\end{frame}
+
+\begin{frame}[fragile]
+\frametitle{\texttt{`tar'}}
+\begin{itemize}
+\item \emph{tarball} -- essentially a collection of files
+\item May or may not be compressed
+\item Eases the job of storing, backing-up \& transporting files
+\end{itemize}
+\end{frame}
+
+\begin{frame}[fragile]
+\frametitle{Extracting an archive}
+\verb~mkdir extract~
+\verb~cp allfiles.tar extract/~
+\verb~cd extract~\\
+\verb~tar -xvf allfiles.tar~
+
+
+\begin{itemize}
+\item \texttt{-x} --- Extract files within the archive
+\item \texttt{-f} --- Specify the archive file
+\item \texttt{-v} --- Be verbose
+\end{itemize}
+\end{frame}
+
+\begin{frame}[fragile]
+  \frametitle{Compressed archives}
+  \begin{itemize}
+  \item \texttt{tar} - create \& extract compressed archives
+  \item Additional option to handle compressed archives
+    \begin{center}
+      \begin{tabular}{|l|l|}\hline
+        Compression      &  Option   \\\hline
+        gzip   &  \texttt{-z}        \\\hline
+        bzip2  &  \texttt{-j}        \\\hline
+        lzma   &  \texttt{-{}-lzma}  \\\hline
+      \end{tabular}
+    \end{center}
+  \end{itemize}
+\end{frame}
+
+
+\begin{frame}
+\frametitle{Customizing your shell}
+\begin{itemize}
+\item Bash reads \texttt{/etc/profile},
+  \texttt{\textasciitilde{}/.bash\_profile},
+  \texttt{\textasciitilde{}/.bash\_login}, and
+  \texttt{\textasciitilde{}/.profile} in that order, when starting
+  up as a login shell. 
+\item \texttt{\textasciitilde{}/.bashrc} is read, when not a login
+  shell 
+\end{itemize}
+\end{frame}

+\frametitle{Summary}
+\label{sec-8}
+
+  In this tutorial, we have learnt to,
+
+
+\begin{itemize}
+\item Use ``find'' command to find files in a directory hierarchy
+\item Find differences between files with the same name, using the
+    ``cmp'' and ``diff'' commands
+\end{itemize}
+\end{frame}
+
+\begin{frame}
+\frametitle{Summary..}
+\label{sec-8}
+
+\begin{itemize}
+\item Extract and create compressed archive's using the ``tar'' command
+\item Customize one's shell according to one's choice
+\end{itemize}
+\end{frame}
+
+\begin{frame}[fragile]
+\frametitle{Evaluation}
+\label{sec-9}
+
+
+\begin{enumerate}
+\item Look at the man page of ``find'' and state the options which
+    deal with symbolic links.
+\vspace{8pt}
+\item How do you append tar files to an archive ?
+\end{enumerate}
+\end{frame}
+\begin{frame}
+\frametitle{Solutions}
+
+\begin{enumerate}
+\item  -H,  -L  and  -P   
+\vspace{15pt}
+\item \$tar -Af <tar-file><tar-file-to-be-added>
+\begin{center}
+OR \\
+\end{center}
+\$tar -rf <tar-file><tar-file-to-be-added>
