So pic unrelated. I'm tryng to get some VNs to work but I'm trying to do it for a buddy of mine that uses an old version of GNU/Ubuntu (9.x). We can't get the .bat to open because they aren't recognized so I made a copy of the file and made it into a .sh, the file type identical to a .bat. The problem is, I'm not very proficient with Ubuntu and he hasn't had to deal with any .sh so we are both stumped, I've looked around online but I'm not finding any real help. Any thoughts or has anyone else done this on Ubuntu?

TL;DR: how do I VN on Ubuntu?
