Your question looks like a DOS batch file. It's not clear what it's supposed to do. The essential part is the java line, you can copy that to a file and insert a line above it which contains the text #!/bin/sh -- mark it as executable and go. This hardly counts as porting the DOS batch file but I don't think the other things it does are useful outside of DOS anyway.

It's not like you can post a badly specified problem here and expect somebody to have diagnosed and solved it two hours later. If you don't get an answer, it's usually because (1) your problem domain is unfamiliar to users of this site, (2) your question doesn't make much sense; or (3) your attitude towards the people who come here to help others dissuades them from helping you. Even so, give it a few days.
