Do you mean assigning value to a property from command line? If so, try

-DpropertyName=itsValue

For example,

<project>
    <target name="hi">
        <property name="person" value="world"/>
        <echo message="Hello ${person}"/>
    </target>
</project>

and then

ant -Dperson="MerryPrankster" hi

yields

 [echo] Hello MerryPrankster
