<body>
<h2 id="unpack">GUnzip/BUnzip2/UnXZ</h2>
<h3>Description</h3>
<p>Expands a resource packed using GZip, BZip2 or XZ.</p>
<p>If <var>dest</var> is a directory the name of the destination file is the same as <var>src</var>
(with the <q>.gz</q>, <q>.bz2</q> or <q>.xz</q> extension removed if present). If <var>dest</var> is
omitted, the parent dir of <var>src</var> is taken. The file is only expanded if the source resource
is newer than the destination file, or when the destination file does not exist.</p>
<p>XZ compression support has been added <em>since Apache Ant 1.10.1</em> and depends on external
libraries not included in the Ant distribution.
See <a href="../install.html#librarydependencies">Library Dependencies</a> for more information.</p>
<h3>Parameters</h3>
<table class="attr">
<tr>
<th scope="col">Attribute</th>
<th scope="col">Description</th>
<th scope="col">Required</th>
</tr>
<tr>
<td>src</td>
<td>the file to expand.</td>
<td>Yes, or a nested resource collection</td>
</tr>
<tr>
<td>dest</td>
<td>the destination file or directory.</td>
<td>No</td>
</tr>
</table>
<h3>Parameters specified as nested elements</h3>
<h4>any <a href="../Types/resources.html">resource</a> or single element resource collection</h4>
<p>The specified resource will be used as <var>src</var>.</p>
<h3>Examples</h3>
<p>Expand <samp>test.tar.gz</samp> to <samp>test.tar</samp></p>
<pre><gunzip src="test.tar.gz"/></pre>
<p>Expand <samp>test.tar.bz2</samp> to <samp>test.tar</samp></p>
<pre><bunzip2 src="test.tar.bz2"/></pre>
<p>Expand <samp>test.tar.xz</samp> to <samp>test.tar</samp></p>
<pre><unxz src="test.tar.xz"/></pre>
<p>Expand <samp>test.tar.gz</samp> to <samp>test2.tar</samp></p>
<pre><gunzip src="test.tar.gz" dest="test2.tar"/></pre>
<p>Expand <samp>test.tar.gz</samp> to <samp>subdir/test.tar</samp> (assuming <samp>subdir</samp> is
a directory).</p>
<pre><gunzip src="test.tar.gz" dest="subdir"/></pre>
<p>Download <samp>https://example.org/archive.tar.gz</samp> and expand it to <samp>archive.tar</samp>
in the project's <var>basedir</var> on the fly.</p>
<pre>
<gunzip dest=".">
<url url="https://example.org/archive.tar.gz"/>
</gunzip>
</pre>
<h3>Related tasks</h3>
<p>The following</p>
<pre><gunzip src="some-archive.gz" dest="some-dest-dir"/></pre>
<p>is identical to</p>
<pre>
<copy todir="some-dest-dir">
<gzipresource>
<file file="some-archive.gz"/>
</gzipresource>
<mapper type="glob" from="*.gz" to="*"/>
</copy></pre>
<p>The same is also true for <code><bunzip2></code> and <code><bzip2resource></code>
or <code><unxz></code> and <code><xzresource></code>. <code><copy></code> offers
additional features like <a href="../Types/filterchain.html">filtering files</a> on the fly,
allowing a file to be mapped to multiple destinations, preserving the last modified time or a
configurable file system timestamp granularity.</p>
