rosls and roscd still missing
I just installed ros-hydro on Ubuntu 12.10 following the tutorial. But when I try to use the command rosls and roscd, it just says command not found. I tried source /opt/ros/hydro/setup.bash a lot of times and there is "source /opt/ros/hydro/setup.bash" in the ~/.bashrc. But rosls and roscd still can't use.
Which package of ROS did you install? The ros-hydro-desktop-full?
Please link to the tutorial you are following and show the commands you are running.
Yes, I install ros-hydro-desktop-full and the like slam-gmapping package.
I followed http://wiki.ros.org/ROS/StartGuide
Stupid question: Do you use bash as your shell?
echo $SHELL returns "/bin/bash"
What is the output of echo $SHELL
From the information you kindly provided in your other question about the same topic what happens if you do sudo apt-get install ros-hydro-rosbash?
