Rickroll the Terminal with curl (Mac)

7:22 AM



friends? Just about nobody is fooled by the random YouTube links anymore, and URL shorteners alone aren’t always enough, but now you can bring the persistently annoying rickrolling to the Terminal of OS X and Linux by running a simple fairly innocuous looking command. What happens when you or the suspect runs it? You’ll get a full ASCII rendition of the infamous Rick Astley video but best of all it’s complete with audio, so be sure they have their speakers turned up or headphones on.

Give it a try yourself and then start rickrolling your friends. Turn your speakers on, launch Terminal, and run the following command:

curl -L http://bit.ly/10hA8iC | bash
Sit back and enjoy those 80′s dance moves in ASCII.

If you’re going to send this to a friend or colleague, be sure to use bitly or another URL shortener to hide the bash script, otherwise with it expanded it reads as “rickrollrc/master/roll.sh” making it quite obvious what’s about to happen.

Important note: It’s exceptionally bad security practice to blindly run random scripts found on the internet, but this one is safe, open source, and viewable on github for those that are curious in seeing how it works.

Oh and if you’re a sys admin or have access to someones .bash_profile, you could really wreak some havoc by aliasing a common command to this, or even use it as your motd if you want to troll everyone that logs into a server or box.

Being April Fools Day, we can’t let the iOS users have all the fun, right?
