command line - Coloured view in vim editor not working in ubuntu 12.04

My Vim editor version VIM - Vi IMproved 7.3 (2010 Aug 15, compiled May 4 2012 04:19:52)

When I open a file(shell script, etc) with it, all the text are on same color. It's not user friendly. How can I solved it?

I tried with adding syntax on in ~/.vimrc file. but no use. It says

E319: Sorry, the command is not available in this version: syntax on

Try sudo apt-get install vim. By default Ubuntu comes with vim-minimal (which does not have syntax highlighting).
