I am not very good at unix command line, but maybe it could be done like this: curl http://get.docker.io > /tmp/docker-install && sh /tmp/docker-install && rm /tmp/docker-install that gives quick and easy way to inspect by executing only first command and then inspecting the source, i.e., 1) copy just first part curl http://get.docker.io > /tmp/docker-install 2) then inspect, e.g. cat /tmp/docker-install 3) run the install sh /tmp/docker-install && rm /tmp/docker-install or, if not reviewing run whole at once

p.s. I know, that there should not be direct copy-paste from browser to console and this method leaves a file in /tmp on installation failure
