Ros launch command not found
I am trying to auto launch a roslaunch file, whenever ubuntu starts. I have written a shell command file "start.sh" and it contains "roslaunch pkg_name file.launch" When i try to execute this shell file in terminal, it runs successfully. But when it runs automatically on start up, the terminal shows "source not found", "roslaunch not found" . Can any one help me correct it. the link to autostarting a sh file is : http://ros-users.122217.n3.nabble.com...
