| <title>Chown Task</title> |

| <h2><a name="Chown">Chown</a></h2> |
| <p><em>Since Ant 1.6.</em></p> |
| <h3>Description</h3> |
| |
| <p>Changes the owner of a file or all files inside specified |
| directories. Right now it has effect only under Unix. The owner |
| attribute is equivalent to the corresponding argument for the chown |
| command.</p> |
| |
| <p><a href="../CoreTypes/fileset.html">FileSet</a>s, |
| <a href="../CoreTypes/dirset.html">DirSet</a>s or <a |
| href="../CoreTypes/filelist.html">FileList</a>s can be specified using |
| nested <code><fileset></code>, <code><dirset></code> and |
| <code><filelist></code> elements.</p> |
| |
| <p>Starting with Ant 1.7, this task supports arbitrary <a |
| href="../CoreTypes/resources.html#collection">Resource Collection</a>s |
| as nested elements.</p> |
| |
| <p>By default this task will use a single invocation of the underlying |
| chown command. If you are working on a large number of files this may |
| result in a command line that is too long for your operating system. |
| If you encounter such problems, you should set the maxparallel |
| attribute of this task to a non-zero value. The number to use highly |
| depends on the length of your file names (the depth of your directory |
| tree) and your operating system, so you'll have to experiment a |
| little. POSIX recommends command line length limits of at least 4096 |
| characters, this may give you an approximation for the number you |
| could use as initial value for these experiments.</p> |

| <tr> |
| <td valign="top">maxparallel</td> |

| <h3>Examples</h3> |
| <blockquote><pre> |
| <chown file="${dist}/start.sh" owner="coderjoe"/> |
| </pre> |
| </blockquote> |
| <p>makes the "start.sh" file belong to coderjoe on a |
| UNIX system.</p> |
| <blockquote> |
| <pre> |
| <chown owner="coderjoe"> |
| <fileset dir="${dist}/bin" includes="**/*.sh"/> |
| </chown> |
| </pre> |
| </blockquote> |
| <p>makes all ".sh" files below <code>${dist}/bin</code> |
| belong to coderjoe on a UNIX system.</p> |
| <blockquote> |
| <pre> |
| <chown owner="coderjoe"> |
| <fileset dir="shared/sources1"> |
| <exclude name="**/trial/**"/> |
| </fileset> |
| <fileset refid="other.shared.sources"/> |
| </chown> |
| </pre> |
| </blockquote> |
| <p>makes all files below <code>shared/sources1</code> (except those |
| below any directory named trial) belong to coderjoe on a UNIX |
| system. In addition all files belonging to a FileSet |
| with <code>id</code> <code>other.shared.sources</code> get the same |
| owner.</p> |
| |
| <blockquote> |
| <pre> |
| <chown owner="webadmin" type="file"> |
| <fileset dir="/web"> |
| <include name="**/*.cgi"/> |
| <include name="**/*.old"/> |
| </fileset> |
| <dirset dir="/web"> |
| <include name="**/private_*"/> |
| </dirset> |
| </chmod> |
| </pre> |
| </blockquote> |
| |
| <p>makes cgi scripts, files with a <code>.old</code> extension or |
| directories beginning with <code>private_</code> belong to the user named |
| webadmin. A directory ending in <code>.old</code> or a file beginning with |
| <code>private_</code> would remain unaffected.</p> |
