Count Links in a Markdown File

Today I learned a great way to count the links in a README or link collection. Vim Regex!

:%s/- \[//n

In Vimspeak:

On every line, find all of the times where - [ (the beginning of a Markdown bulleted hyperlink) occurs, count them, and report the number of matches.

See :help substitute in Vim for more information.
