Right now it has effect only under Windows. Each of the 4 possible permissions has its own attribute, matching the arguments for the attrib command.</p> <p><a href="../Types/fileset.html">FileSet</a>s, <a href="../Types/dirset.html">DirSet</a>s or <a href="../Types/filelist.html">FileList</a>s can be specified using nested <code><fileset></code>, <code><dirset></code> and <code><filelist></code> elements.</p> <p><em>Since Ant 1.7</em>, this task supports arbitrary <a href="../Types/resources.html#collection">resource collections</a> as nested elements.</p> <!--p>By default this task will use a single invocation of the underlying attrib 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), so you'll have to experiment a little.</p--> <p>By default this task won't do anything unless it detects it is running on a Windows system. If you know for sure that you have a <code>attrib</code> executable on your <code>PATH</code> that is command line compatible with the Windows command, you can use the task's <var>os</var> attribute and set its value to your current OS.</p> <p>See the <a href="setpermissions.html">setpermissions</a> task for a platform independent alternative.</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>file</td> <td>the file or directory of which the permissions must be changed.</td> <td>Yes, or nested <code><fileset/list></code> elements</td> </tr> <tr> <td>readonly</td> <td>the readonly permission.</td> <td rowspan="4">At least one of the four</td> </tr> <tr> <td>archive</td> <td class="left">the archive permission.</td> </tr> <tr> <td>system</td> <td class="left">the system permission.</td> </tr> <tr> <td>hidden</td> <td class="left">the hidden permission.</td> </tr> <tr> <td>type</td> <td>One of <q>file</q>, <q>dir</q> or <q>both</q>.
