<h2 id="chgrp">Chgrp</h2>
|
||||
<p><em>Since Apache Ant 1.6</em>.</p>
|
||||
<h3>Description</h3>
|
||||
|
||||
<p>Changes the group of a file or all files inside specified directories. Right now it has effect
|
||||
only under Unix. The group attribute is equivalent to the corresponding argument for
|
||||
the <kbd>chgrp</kbd> 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 <kbd>chgrp</kbd> 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 <var>maxparallel</var>
|
||||
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>
|
||||
|
||||
<p>By default this task won't do anything unless it detects it is running on a Unix system. If you
|
||||
know for sure that you have a <kbd>chgrp</kbd> executable on your <code>PATH</code> that is
|
||||
command line compatible with the Unix command, you can use the task's <var>os</var> attribute and
|
||||
set its value to your current OS.</p>

<h3>Examples</h3>
|
||||
|
||||
<p>Make the <samp>start.sh</samp> file belong to the <samp>coders</samp> group on a UNIX system.</p>
|
||||
<pre><chgrp file="${dist}/start.sh" group="coders"/></pre>
|
||||
|
||||
<p>Make all <samp>.sh</samp> files below <samp>${dist}/bin</samp> belong to the <samp>coders</samp>
|
||||
group on a UNIX system.</p>
|
||||
<pre>
|
||||
<chgrp group="coders">
|
||||
<fileset dir="${dist}/bin" includes="**/*.sh"/>
|
||||
</chgrp></pre>
|
||||
|
||||
<p>Make all files below <samp>shared/sources1</samp> (except those below any directory
|
||||
named <samp>trial</samp>) belong to the <samp>coders</samp> group on a UNIX system. In addition, all
|
||||
files belonging to a FileSet with <var>id</var>=<samp>other.shared.sources</samp> get the same
|
||||
group.</p>
|
||||
<pre>
|

<chgrp group="coders">
|

<fileset dir="shared/sources1">
|

<exclude name="**/trial/**"/>

</fileset>
|
||||
<fileset refid="other.shared.sources"/>
|
||||
</chgrp>
|
||||
</pre>
|
||||
|
||||
<p>Make all <samp>.test.jsp</samp>, and <samp>.new</samp> files belong to
|
||||
group <samp>webdev</samp>. Directories with names beginning with <samp>test_</samp> also will belong
|
||||
to <samp>webdev</samp>, but if there is a directory name that ends in <samp>.new</samp> or a file
|
||||
name that begins with <samp>test_</samp> it will be unaffected.</p>
