The default editor for rosed is vim. To set the default editor to something else edit your ~/.bashrc file to include: export EDITOR='emacs -nw' But I don't know how to edit the ~/.bashrc file.

To edit it:

vi ~/.bashrc

and add that line. You could also use (as SaiHV answered)

gedit ~/.bashrc".

Make sure to

source ~/.bashrc

after editing it.

Use "gedit ~/.bashrc".

After you edit it you need to open a new terminal for it to take effect.

I just opened the .bashrc file and noticed that the command source /opt/ros/hydro/setup.bash is already there. I think in the Hydro distribution they have added the command into .bashrc file to bring more ease to life.

No; ROS does not automatically modify your .bashrc . You either added that line (possibly by following the setup directions) or your local system administrator put it there for you.
