<title>Chmod Task</title>

<body>

<h2><a name="chmod">Chmod</a></h2>
<h3>Description</h3>
<p>Changes the permissions of a file or all files inside specified
directories. Right now it has effect only under Unix or NonStop Kernel (Tandem).
The permissions are also UNIX style, like the argument for the chmod command.</p>
<p>See the section on <a href="../dirtasks.html#directorybasedtasks">directory based
tasks</a>, on how the inclusion/exclusion of files works, and how to
write patterns.</p>
<p>This task holds an implicit <a href="../CoreTypes/fileset.html">FileSet</a> and
supports all of FileSet's attributes and nested elements
directly. More FileSets can be specified using nested
<code>&lt;fileset&gt;</code> elements.</p>

<p>Starting with Ant 1.6, this task also supports nested <a
href="../CoreTypes/filelist.html">filelist</a>s.</p>
