Using Vim as a note-taking app

Vim allows you to run Ex commands using -c. For example, typing

vim -c 'r!date'

will read the output of date to the buffer.

Making it useful

We can chain commands to turn it into a Markdown note-taking app:

vim -c 'r!date' -c 'normal i# ' ~/

Now every time you run that command, Vim will add a header with the current date at the top. Alias it to note to easily jot down notes from the terminal.
