I know how to turn syntax highlighting on and off in vim by running this in the editor:
:syntax on/off
But I want syntax highlighting to be
Edit your $HOME/.vimrc (Unix/Linux/OSX) or $HOME/_vimrc (Windows) to include the following line:
syntax on
EDIT
If your syntax highlighting doesn't work when you start Vim, you probably don't have a
$HOME/.vimrc or $HOME/_vimrc (known collectively as vimrc from now on). In that case, you have two options:
vimrc.vimrc_example.vim as your vimrc (recommended, thanks @oyenamit). You can find vimrc_example.vim in the runtime directory.The location of the runtime directory varies between operating systems:
/usr/share/vim/vim73.\Program Files\Vim\vim73.
