how can I check which version of vim I have installed?

Question

I'm running Mac OS X Snow Leopard. How can I check which version of vim I have installed?

Ideally I'd like to know a general solution for checking software versions via the command line.

Answer 1

The command:

vim --version

This is pretty standard for all unix executables.

Answer 2

or, just if you run vim already and want to know what you are in right now:

:version

Answer 3

In a terminal run vim --version ther version number is in the top line of output.

Answer 4

You can also just open a blank VIM document by typing vi or vim in your terminal. The welcome screen will state your version as well as other information.

Answer 5

For vim or neovim using regex:

vi --version | grep -oP '(?<=^VIM v)[0-9|.]+'
vi --version | grep -oP '(?<=^NVIM v)[0-9|.]+'

Assumes your grep has perl compatible regex (PCRE).
