<h2 class="chapter">10 Pattern Matching</h2>

<p>The GNU C Library provides pattern matching facilities for two kinds of
patterns: regular expressions and file-name wildcards.  The library also
provides a facility for expanding variable and command references and
parsing text into words in the way the shell does.

<ul class="menu">
<li><a accesskey="1" href="Wildcard-Matching.html#Wildcard-Matching">Wildcard Matching</a>:     Matching a wildcard pattern against a single string. 
<li><a accesskey="2" href="Globbing.html#Globbing">Globbing</a>:              Finding the files that match a wildcard pattern. 
<li><a accesskey="3" href="Regular-Expressions.html#Regular-Expressions">Regular Expressions</a>:   Matching regular expressions against strings. 
<li><a accesskey="4" href="Word-Expansion.html#Word-Expansion">Word Expansion</a>:        Expanding shell variables, nested commands,
			    arithmetic, and wildcards. 
			    This is what the shell does with shell commands. 
</ul>
