typing \end{verbatim}

Question

I am preparing a presentation in which I want to display the following as it is

\begin{verbatim}
foo
\end{verbatim}

For this I used

\begin{verbatim}
\begin{verbatim}
foo
\end{verbatim}
\end{verbatim}

But the first \end{verbatim} ends the environment and the second induces error. Can anyone suggest how to do this?

I should appreciate the explanation of the trick and commands suggested.

Answer 1

Try

\usepackage{verbatim}
\verb+\begin{verbatim} foo \end{verbatim}+

or, if you want it on separate lines

\verb+\begin{verbatim}+\\
\verb+foo+\\
\verb+\end{verbatim}+

or, if foo is long,

\verb+\begin{verbatim}+
\begin{verbatim}
foo
\end{verbatim}
\verb+\end{verbatim}+

Answer 2

You can create a new environment that ensembles the verbatim environment, like:

\documentclass{article}
\usepackage{verbatim}
\newenvironment{realverbatim}{\verbatim}{\endverbatim}

\begin{document}
Test of the new \verb~verbatim~ environment:

\begin{realverbatim}
\begin{verbatim}
foo
\end{verbatim}
\end{realverbatim}

\end{document}

Answer 3

I don't think that there is any really sensible trick which will work with verbatim directly. I would use another verbatim-like environment from the listings or the fancyvrb package.
