\section{\module{fnmatch} ---

\UNIX{} filename pattern matching}

\declaremodule{standard}{fnmatch}
|
|
\modulesynopsis{\UNIX{} shell style filename pattern matching.}
|
|
|
|
|
|
This module provides support for \UNIX{} shell-style wildcards, which
|
|
are \emph{not} the same as regular expressions (which are documented
|
|
in the \refmodule{re}\refstmodindex{re} module). The special
|
|
characters used in shell-style wildcards are:
|
|
\index{filenames!wildcard expansion}
|
|
|
|
\begin{list}{}{\leftmargin 0.5in \labelwidth 0.45in}
|
|
\item[\code{*}] matches everything
|
|
\item[\code{?}] matches any single character
|
|
\item[\code{[}\var{seq}\code{]}] matches any character in \var{seq}
|
|
\item[\code{[!}\var{seq}\code{]}] matches any character not in \var{seq}
|
|
\end{list}
|
|
|
|
Note that the filename separator (\code{'/'} on \UNIX{}) is \emph{not}
|
|
special to this module. See module
|
|
\refmodule{glob}\refstmodindex{glob} for pathname expansion
|
|
(\refmodule{glob} uses \function{fnmatch()} to match filename
|
|
segments).
|
|
|
|
|
|
\begin{funcdesc}{fnmatch}{filename, pattern}
|
|
Test whether the \var{filename} string matches the \var{pattern}
|
|
string, returning true or false. If the operating system is
|
|
case-insensitive, then both parameters will be normalized to all
|
|
lower- or upper-case before the comparision is performed. If you
|
|
require a case-sensitive comparision regardless of whether that's
|
|
standard for your operating system, use \function{fnmatchcase()}
|
|
instead.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{fnmatchcase}{filename, pattern}
|
|
Test whether \var{filename} matches \var{pattern}, returning true or
|
|
false; the comparision is case-sensitive.
|
|
\end{funcdesc}
