# B.37 ReflexiveTask
The `ReflexiveTask` performs operations on files. It is essentially a convenient way to transform (using filter chains) files without copying them.
Table B.37:聽Attributes
NameTypeDescriptionDefaultRequired`file``String`A single file to be processed.n/aYes (unless <fileset> provided)
B.37.1 Examples
```
<reflexive>
<fileset dir=".">
<include pattern="*.html">
</fileset>
<filterchain>
<replaceregexp>
<regexp pattern="\r(\n)" replace="\1"/>
</replaceregexp>
</filterchain>
</reflexive>
