I am wanting to find a UNIX simulator, pref a shareware or freeware I can download. If anyone can help it would be greatly appreciated.
Not to be strange sounding, but why don't you download the real-thing (Linux, BSDI, FreeBSD, etc. vs. a 'simulator' ?
.... just curious 
Well Neo, that is a good idea and that would be great, but I want to use it at school and I can't format the hard drives here 
If I can't find one I will end up doing that at home, but it would be nice.
They do make some UNIX-shells that will install and work on Windows. Check this out and see if this helps:
