What follows is probably the most perverse shell script I have ever written. I decided to write a script that somehow implemented Hello World for a bunch of languages. I didn’t include Java, because the installation of java on the machine I wrote this script on was somehow messed up. Plus, Java sucks hard. I didn’t do any javascript either as Rhino was messed up (see last sentence), and spidermonkey wasn’t installed. I included far too many, but I will gladly add more if someone bothers to write some. You can also download the file. Wordpress messed a few things up, which I tried to correct, so download the file copy if you actually want to try thing thing out. Also, you might need to install some stuff unless you are in the UofC CS department Linux clusters. I apologize to the world for what my boredom can cause…
