Nix: Standard output to clipboard buffer

Adding | pbcopy to the end of any command will send the standard output to your clipboard.

ls -al | pbcopy inside a rails project directory allowed me to paste this:

Gemfile
Gemfile.lock
README.md
Rakefile
app
bin
config
config.ru
db
features
lib
log
public
script
spec
test
tmp
vendor
