[ros-users] rosbash: roscd magic for cleaner title/prompt

[Ivan Dryanovski]

Hi Radu,

I tried running the same sequence of commands and it doesn't hang on
my machine. But you are right that mixing roscd and cd creates
problems. The scripting I did was a pretty quick hack into the roscd
machine - there might be a more robust way to handle the switching.
