Hm, it just popped into my mind that you may be trying on a filesystem that does not support modes (such as vfat). That would explain it. I'm trying in /home/user which is ext3. Anyway, sh ./profile.sh (or whatever the name of the file is) should work anyway, so just add a preceding 'sh' and you should be fine. I'll fix the first post in this thread.

Thanks, Matt
