Since Ant 1.6.
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.
Starting with Ant 1.7, this task supports arbitrary Resource Collections as nested 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.
Attribute | Description | Required |
file | the file or directory of which the owner must be changed. | Yes or nested
<fileset/list> elements. |
owner | the new owner. | Yes |
parallel | process all specified files using a single
chown command. Defaults to true. |
No |
type | One of file, dir or
both. If set to file, only the owner of
plain files are going to be changed. If set to dir, only
the directories are considered. Note: The type attribute does not apply to nested dirsets - dirsets always implicitly assume type to be dir. |
No, default is file |
maxparallel | Limit the amount of parallelism by passing at most this many sourcefiles at once. Set it to <= 0 for unlimited. Defaults to unlimited. | No |
verbose | Whether to print a summary after execution or not.
Defaults to false . |
No |
<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.
