Error in curl command to download example code in tf2 tutorial

[songyuc]

The tutorial "Using Stamped Datatypes With Tf2 & Ros MessageFilter" contains an error in the curl command to download the example code file turtle_tf2_message_filter.cpp.

The command provided is:

curl -sk wget [https://raw.githubusercontent.com/ros/geometry\_tutorials/ros2/turtle\_tf2\_cpp/src/turtle\_tf2\_message\_filter.cpp](https://raw.githubusercontent.com/ros/geometry_tutorials/ros2/turtle_tf2_cpp/src/turtle_tf2_message_filter.cpp) -o turtle\_tf2\_message\_filter.cpp

When running this on Windows, it results in an "Empty reply from server" error.

The issues is using both curl and wget in the same command

Please consider updating the tutorial to fix this command so users can download the code properly.

Let me know if any other details need to be included in the issue submission.
