How to remove several lines in the Vim editor using Regex
A quick tip for those who use Vim: if you need to remove several lines that match your regular expression, you can achive that by running
viml:g /pattern/d
Let's say you want to remove the commented lines from the following file:
ruby# This is a comment def foo end # This is another comment def bar end
Run :g /^#.*/d
and your code will become:
rubydef foo end def bar end
Simple, hey? :)
