In math mode:

\| is a double pipe: ||

\text{\textbar} is a single pipe: | (requires the amsmath package)

The pipe symbol may be used directly in the input and will produce the desired output if you use T1 font encoding. For example:

\documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
Pipe sign: |
\end{document}

See Special LaTeX characters for such an example with its output and more information.

\textpipe or use something like \big| when in math mode.

write: \textpipe

Here you have the handbook of latex symbols: The Comprehensive LATEX Symbol List

\textpipe requires loading a package, for instance tipa or t4phonet. – Stefan Aug 15 '10 at 15:50

Using \textbar will give the pipe symbol.
