Chown

Since Ant 1.6.

Description

Changes the owner of a file or all files inside specified directories. Right now it has effect only under Unix. The owner attribute is equivalent to the corresponding argument for the chown command.

FileSets, DirSets or FileLists can be specified using nested <fileset>, <dirset> and <filelist> elements.

By default this task will use a single invocation of the underlying chown 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) 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.

Parameters

Examples

<chown file="${dist}/start.sh" owner="coderjoe"/>

makes the "start.sh" file belong to coderjoe on a UNIX system.

    <chown owner="coderjoe">
      <fileset dir="${dist}/bin" includes="**/*.sh"/>
    </chown>

makes all ".sh" files below ${dist}/bin belong to coderjoe on a UNIX system.

<chown owner="coderjoe">
  <fileset dir="shared/sources1">

    <exclude name="**/trial/**"/>
  </fileset>
  <fileset refid="other.shared.sources"/>
</chown>

makes all files below shared/sources1 (except those below any directory named trial) belong to coderjoe on a UNIX system. In addition all files belonging to a FileSet with id other.shared.sources get the same owner.

<chown owner="webadmin" type="file">

  <fileset dir="/web">
    <include name="**/*.cgi"/>
    <include name="**/*.old"/>
  </fileset>

  <dirset dir="/web">
    <include name="**/private_*"/>
  </dirset>
</chmod>

makes cgi scripts, files with a .old extension or directories beginning with private_ belong to the user named webadmin. A directory ending in .old or a file beginning with private_ would remain unaffected.
