<h2 class="chapter">4 <code>gprof</code> Command Summary</h2>

<p>After you have a profile data file <samp>gmon.out</samp>, you can run <code>gprof</code>
to interpret the information in it.  The <code>gprof</code> program prints a
flat profile and a call graph on standard output.  Typically you would
redirect the output of <code>gprof</code> into a file with &lsquo;<samp>&gt;</samp>&rsquo;.
</p>
<p>You run <code>gprof</code> like this:
</p>
<div class="smallexample">
<pre class="smallexample">gprof <var>options</var> [<var>executable-file</var> [<var>profile-data-files</var>&hellip;]] [&gt; <var>outfile</var>]
</pre></div>

<p>Here square-brackets indicate optional arguments.
</p>
<p>If you omit the executable file name, the file <samp>a.out</samp> is used.  If
you give no profile data file name, the file <samp>gmon.out</samp> is used.  If
any file is not in the proper format, or if the profile data file does not
appear to belong to the executable file, an error message is printed.
</p>
<p>You can give more than one profile data file by entering all their names
after the executable file name; then the statistics in all the data files
are summed together.
</p>
<p>The order of these options does not matter.
