By the way, you might like to ask Vim-related questions on the Vi and Vim StackExchange site — joeytwiddle, Jan 08 '16 at 09:28

O.o You don't have to use those settings - the relevant point is that ~/.vimrc is the file to be modified. — muru, Jan 08 '16 at 10:50

You could add this to your ~/.vimrc file:

set number

But if you want that to happen only on files with txt extension:

autocmd BufReadPost *.txt set number

or perhaps better, on any file which Vim detects is a text file:

autocmd FileType text set number
