intertwingly

I’m posting this in case I’m not the last person to realize this.  While I’ve used the Unix sh longer than DHH has been alive, I either never realized or have long since forgotten that it supports here documents.  Example:

ruby <<EOD | sort | uniq -c | sort -n
  Dir['*'].each do |name|
     puts name.split('.',0)[1] || '<null>'
  end
EOD
