   \begin{itemize}
-  \item The command below sorts, based on marks in first subject
+  \item The standard output (stdout) stream goes to the display
+  \item May not be always, what we need
+  \item \texttt{>} states that output is redirected to the specified location 
+  \item It is followed by location to redirect,
   \end{itemize}

-    $ cut -d " " -f 2- marks1.txt \

+\end{frame}

+\begin{frame}[fragile]
+  \frametitle{Redirection..} 
   \begin{itemize}
-  \item \texttt{-t} specifies the delimiter between fields
-  \item \texttt{-k} specifies the field to use for sorting
-  \item \texttt{-r} for sorting in the reverse order
-  \item \texttt{-n} to choose numerical sorting
+  \item Similarly, the standard input (stdin) can be redirected as
+  \end{itemize}
+  \hspace{29pt}\texttt{\$ command < file1}
+  \begin{itemize}
+  \item input and output redirection could be combined
+  \end{itemize}
+  \hspace{29pt}\texttt{\$ command < infile > outfile}
+\end{frame}
+
+\begin{frame}
+\frametitle{stderr}
+  \begin{itemize}
+  \item Standard error (stderr) is the third standard stream
+  \item All error messages come through this stream
+  \item \texttt{stderr} can also be redirected

+$ cut -d " " -f 2- marks1.txt 
+  | paste -d " " students.txt -
+  \end{lstlisting} % $
+  \begin{itemize}
+  \item \texttt{-} at the end asks \texttt{paste} to read from
+    \texttt{stdin} instead of FILE 
+  \item \texttt{cut} command here is a normal command
+  \end{itemize}
+\end{frame}
+
+\begin{frame}[fragile]
+\frametitle{Piping..}
+\begin{itemize}
+  \item the \texttt{|} seems to be joining the two commands
+  \item Redirects output of first command to \texttt{stdin}, which
+    becomes input to the second command
+  \item This is called piping; \texttt{|} is called a pipe
   \end{itemize}
 \end{frame}
 
 \begin{frame}[fragile]

+  \frametitle{Piping..}
   \begin{itemize}
-  \item Translates or deletes characters
-  \item Reads from \texttt{stdin} and outputs to \texttt{stdout}
-  \item Given, two sets of characters, replaces one with other
-  \item The following, replaces all lower-case with upper-case 
+  \item Roughly same as -- two redirects and a temporary file
   \end{itemize}
   \begin{lstlisting}
-    $ cat students.txt | tr a-z A-Z
