My local machine is a laptop running Ubuntu 10.04 (old, I know). While collecting data during my experiments, I am generating text files for Matlab, but I want to organize a single experiment into a new directory. Here is my test code (found on an ANT reference page):

<!-- -*- mode: XML -*-  -->
<launch>
  <mkdir dir="/home/turtlebot/00x/"/>
  <!-- Other Stuff excluded as irrelevant -->
</launch>

Does anyone know a way to have a directory (in this case /00x/) automatically generated using XML?

I made a shell script and called it this way: <node pkg="hast" type="makedir.sh" name="makeDir" output="screen"/>

Also, nodes can be shell scripts, making directory creation pretty straightforward.

I found this interesting hack in maxwell_calibration:

  <node type="record" pkg="rosbag" name="robot_measurement_recorder" output="screen"
        args="-O /tmp/maxwell_calibration/cal_measurements robot_measurement robot_description" >
    <!-- Hack to create the directory -->
    <param name="mkdir_tmp" command="mkdir -m 777 -p /tmp/maxwell_calibration" />
  </node>

So it appears you can create folders from launch files (using very hacky abuse of parameters)
