Command not detected -> roscd: command not found

Many commands like roscd, rosls, roslaunch are not working. Errors are thrown as :- roscd: command not found

What may be the reasons behind this?

you need to setup you environment and add variables to your bash just use the following commands..

echo "source 'your setup.bash file path'" >> ~/.bashrc
source ~/.bashrc

It seems that your setup.bash hasn't been sourced in a terminal window.

Try executing this command:

source /opt/ros/hydro/setup.bash

If that won't work try following the steps on site bellow, as they are beautifully explained on how to install ROS on Ubuntu.
