# How do I get selective bold in Verbatim? [duplicate]

I previously wrote a computer professional book in which I showed what the user typed on the console and the computer's resultant output. The way I liked to do this was with everything in courier and with the user's input in bold. Something like this:

<tt>
$<b>echo foo</b> foo$
</tt>


I typed this as HTML because I don't know how to do this in Markdown (what StackExchange uses) and I don't know how to easily do it in LaTeX. I can certainly do it with \texttt{\$\textbf{echo foo}}, but I would rather not have to quote everything. I don't want to use lstlisting as recommended by Using bold/italic text inside listings?, because I don't want LaTeX deciding what's bold. Any other recommendations? ## 2 Answers If you only need fancyvrb and not the full fledged listings package, you can do it quite easily with the commandchars option: \documentclass{article} \usepackage{fancyvrb} \newcommand\userinput[1]{\textbf{#1}} \usepackage{tgcursor} \begin{document} \begin{Verbatim}[commandchars=\\\{\}]$ \userinput{echo foo}
foo
$\end{Verbatim} \begin{Verbatim}[commandchars=\#]$ #userinput[echo \]
> #userinput[foo]
foo
$\end{Verbatim} \end{document}  The triple of escaped characters can consist of anything is not used in the Verbatim environment. Another option, that is less flexible than egreg's, is to use the alltt package. \documentclass{article} \usepackage{alltt} \begin{document} \begin{alltt}$ {\bf echo foo}
foo
\$
\end{alltt}
\end{document}

• This makes the section bold, but it's not in typewriter font. – Charles Clayton Oct 23 '16 at 3:29
• @crclayton True. To correct that, it would in principle be enough to change {\bf to \textbf{, but in practice this gives non-bold typewriter font, likely because the appropriate combination is not found. egreg fixes that by adding the package tgcursor. – Bruno Le Floch Oct 23 '16 at 10:50
