As we know that vi editor has three modes namely: command mode,input mode & ex mode.By default,we get the command mode when the editor is evoked. Also we can navigate to other modes by using suitable commands like "i",":" etc. My problem is that when I press backspace in input mode,it doesn't erase the character unlike in the same editor that I have worked in RedHat does. I want to be clear about it.
i
in vi?sudo apt-get install vim
