I use Vim 6+. I like to have basic things set up on vim to get going. Often though, I do not remember the setting commands. Simple things like syntax highlighting, auto-numbering of file lines, auto indentation, tab expansion and tab width in character spaces.
After installing vim on your POSIX compliant machine, go to your home directory and edit or create the new .vimrc file:
user@machine:~$ cd && vim .vimrc
Below is what I enter to get started:
:set syntax=on :set number :set autoindent :set expandtab :set shiftwidth=2 :set softtabstop=2
