<h3 class="section">F.5 Using <code>occur</code></h3>
<p><a name="index-Occurrences_002c-listing-with-_0040code_007b_0040_0040occur_007d-1465"></a><a name="index-occur-1466"></a>
Sometimes the <code>texinfo-show-structure</code> command produces too much
information. Perhaps you want to remind yourself of the overall structure
of a Texinfo file, and are overwhelmed by the detailed list produced by
<code>texinfo-show-structure</code>. In this case, you can use the <code>occur</code>
command directly. To do this, type
<pre class="example"> <kbd>M-x occur</kbd>
</pre>
<p class="noindent">and then, when prompted, type a <dfn>regexp</dfn>, a regular expression for
the pattern you want to match. (See <a href="../emacs/Regexps.html#Regexps">Regular Expressions</a>.) The <code>occur</code> command works from
the current location of the cursor in the buffer to the end of the
buffer. If you want to run <code>occur</code> on the whole buffer, place
the cursor at the beginning of the buffer.
<p>For example, to see all the lines that contain the word
‘<samp><span class="samp">@chapter</span></samp>’ in them, just type ‘<samp><span class="samp">@chapter</span></samp>’. This will
produce a list of the chapters. It will also list all the sentences
with ‘<samp><span class="samp">@chapter</span></samp>’ in the middle of the line.
<p>If you want to see only those lines that start with the word
‘<samp><span class="samp">@chapter</span></samp>’, type ‘<samp><span class="samp">^@chapter</span></samp>’ when prompted by
<code>occur</code>. If you want to see all the lines that end with a word
or phrase, end the last word with a ‘<samp><span class="samp">$</span></samp>’; for example,
‘<samp><span class="samp">catching mistakes$</span></samp>’. This can be helpful when you want to see
all the nodes that are part of the same chapter or section and
therefore have the same `Up' pointer.
<p>See <a href="../emacs/Other-Repeating-Search.html#Other-Repeating-Search">Using Occur</a>,
for more information.
