|
|
<p>The <span class="sc">gnu</span> <samp><span class="command">size</span></samp> utility lists the section sizes—and the total
|
|
size—for each of the object or archive files <var>objfile</var> in its
|
|
argument list. By default, one line of output is generated for each
|
|
object file or each module in an archive.
|
|
|
|
<p><var>objfile</var><small class="dots">...</small> are the object files to be examined.
|
|
If none are specified, the file <code>a.out</code> will be used.
|
|
|
|
<!-- man end -->
|
|
<!-- man begin OPTIONS size -->
|
|
<p>The command line options have the following meanings:
|
|
|
|
<dl>
|
|
<dt><samp><span class="env">-A</span></samp><dt><samp><span class="env">-B</span></samp><dt><samp><span class="env">--format=</span><var>compatibility</var></samp><dd><a name="index-g_t_0040command_007bsize_007d-display-format-119"></a>Using one of these options, you can choose whether the output from <span class="sc">gnu</span>
|
|
<samp><span class="command">size</span></samp> resembles output from System V <samp><span class="command">size</span></samp> (using <samp><span class="option">-A</span></samp>,
|
|
or <samp><span class="option">--format=sysv</span></samp>), or Berkeley <samp><span class="command">size</span></samp> (using <samp><span class="option">-B</span></samp>, or
|
|
<samp><span class="option">--format=berkeley</span></samp>). The default is the one-line format similar to
|
|
Berkeley's.
|
|
<!-- Bonus for doc-source readers: you can also say -format=strange (or -->
|
|
<!-- anything else that starts with 's') for sysv, and -format=boring (or -->
|
|
<!-- anything else that starts with 'b') for Berkeley. -->
|
|
|
|
<p>Here is an example of the Berkeley (default) format of output from
|
|
<samp><span class="command">size</span></samp>:
