I think this might be due to having the wrong type of line endings in the shell script file. I'd try opening a new empty file in TextEdit, then cutting and pasting each line from the shell script into the new empty file. When you've done this, save the file with a .sh extension. You might need to issue chmod command to give it execute permission (eg. chmod 777 newcommandfile.sh) before you can run it.

On the Mac, javac doesn't recognize the '-cp' option; use '-classpath' instead. It's possible that javac is complaining about the wrong error.

Typing "javac" with no parameters in Terminal brings up both "-classpath" and "-cp" as equivalent options. Not recognising -cp would be a definite bug which you should report.

Ah. I must have an older version -- it doesn't list '-cp' as an option.
