Please try usng the packages "boxedminipage" and "fanvyvrb", as below:

  \begin{boxedminipage}{14cm}
    \textbf{Note:} One of the problems with \textsc{Unix} as an ``open
    system'' is that a variety of people have developed \textsc{Unix}
    commands, shells and other tools.  There is no corporate ``big
    brother'' making sure that all of the commands work the same way.
    The above construct is a case in point.
    In Bourne shell and Korn shell the correct usage is as above:
    \begin{Verbatim}
      ls .[!.]*
    \end{Verbatim}
    
    But, for \texttt{tcsh} (the default login shell on CS\&IT systems),
    \texttt{csh}, \texttt{zsh}, BASH and probably a few other shells
    that use command history systems, the ``!'' character is used to
    signify a substitution from the command history.
  
    On these shells, to get the same result you would need to use:
    \begin{Verbatim}
      ls .[^.]*
    \end{Verbatim}
    \end{boxedminipage}

I think plain "verbatim" package works here, but you may need "fancyvrb"
to do some fncy things later.
