Giving vim a colour scheme

Changing the default vim theme is quite simple yet so many don't bother to spend two minutes to improve their quality of life dramatically.

Here's how to do it:

Download the 256-grayvim.vim colour scheme or any other scheme you like. Make sure that the 256-grayvim.vim file ends up in the following directory (you'll need to be root):

/usr/share/vim/vimXX/colors/
(replace XX with the installed vim version, e.g. 71, 73, or 74)

Then add the colour scheme as default for all users:

vim /usr/share/vim/vimrc

Add the following to the very bottom of the file:

colorscheme 256-grayvim

Save and exit. Next time you open any file with vim the colour scheme should be applied.
