Changing the section format

Question

Consider the \section{abc}

the output will be like

1. abc

how can I change the '.' to '-' or vice versa. i.e.

2- abc

This is not necessarily true. What class are you using? A naive hack for the article class would be \makeatletter\renewcommand\thesection{\@arabic\c@section-}\makeatother ... but look at what that does to the Table of Contents (or if you also have subsections). It is therefore best to provide a minimal example (or here). — jon, Jun 18 '13 at 05:58

Redefining \thesection doesn't help, because this will give wrong results when referencing a section number.

A “package free” solution is to access the \@seccntformat feature:

\documentclass{article}
\makeatletter
\renewcommand{\@seccntformat}[1]{%
  \csname the#1\endcsname\ --\ }
\makeatletter

\begin{document}
\section{Introduction}\label{sec:intro}

We're in section~\ref{sec:intro}.
\end{document}

You can use

\renewcommand{\thesection}{\arabic{section}-}

for that specific purpose. Note that you could also use roman, Roman, alph or Alph instead of arabic, and you can also customize further by adding \thechapter, for instance.

Unfortunately this is wrong. References to sections will contain the dash, which is certainly unwanted. – egreg Jun 18 '13 at 08:31

Without an additional knowledge about usage it may be simply (see probably corrected spacing):

\documentclass{article}

\def\thesection{\arabic{section}--\hspace{-1em}}
\begin{document}

\section{First}

\end{document}

Did you try doing \ref{sec:whatever} when the label is linked to a section? – egreg Jun 18 '13 at 08:25
@egreg I know, that ALL should be labelled "Achtung! Minen!", but without the requested usage I choose such a solution. – Przemysław Scherwentke Jun 18 '13 at 08:36
