Ros is permenantly installed after following the installation steps?
Hey, i wanted to ask when i follow the installation steps given on the site, i execute the commands" Ubuntu install of ROS Jade" and when i reach the end do i need to verify that ros is installed? When i close the terminal ROS vanishes? How can i know that whenever i open UBUNTU Ros will be installed?
Because when i go through the steps and verify by typing "ros versionros" it says"unversioned" and when i close and open terminal again it says"command ros not found" i know it maybe a silly question but i am a newbie:)
