|
2018-01-24 21:40:28 +01:00
|
|
|
<p><em>Since Apache Ant 1.6</em>.</p>

2002-11-07 15:59:47 +00:00

<h3>Description</h3>
|
|
|
|
|
|
2018-02-28 07:58:59 +01:00
|
|
|
<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
|
2018-03-10 20:17:33 +01:00
|
|
|
the <kbd>chgrp</kbd> command.</p>
|
2018-02-28 07:58:59 +01:00
|
|
|
|
|
|
|
|
<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
|
2018-03-05 17:35:30 +01:00
|
|
|
arbitrary <a href="../Types/resources.html#collection">resource collections</a> as nested
|
2018-02-28 07:58:59 +01:00
|
|
|
elements.</p>
|
|
|
|
|
|
2018-03-10 20:17:33 +01:00
|
|
|
<p>By default this task will use a single invocation of the underlying <kbd>chgrp</kbd> command.
|
2018-02-28 07:58:59 +01:00
|
|
|
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
|
2018-03-10 20:17:33 +01:00
|
|
|
know for sure that you have a <kbd>chgrp</kbd> executable on your <code>PATH</code> that is
|
2018-02-28 07:58:59 +01:00
|
|
|
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>
