Dear Mr. Moses
As I'm using the listings package to print some bash commands, I find that all hyphen in the command turned into minus sign. How could I get hyphens? I hope to receive your help.
The context of my latex file list below:
\lstdefinestyle{cmds}{
basicstyle=\small,
columns=fullflexible,
language=bash,
prebreak=\space,
numbers=left,numberstyle=\tiny,stepnumber=2,numbersep=5pt,
tabsize=2,frame=leftline,
breaklines=true,
breakatwhitespace=true,
extendedchars=false
}
..........................
\begin{lstlisting}[style=cmds]
sudo apt-get install texlive-full latex-beamer latex-cjk-all fontforge
\end{lstlisting}
