<h2 id="attrib">Attrib</h2>
|
|
<p><em>Since Apache Ant 1.6</em>.</p>
|
|
<h3>Description</h3>
|
|
|
|
<p>Changes the attributes of a file or all files inside specified directories. 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>
