It's really not clear what you want to do,
other than that it would seem to be highly insecure.
So to answer some of the possible interpretations of
this question:
executing command.com -c dir should
run the built in dir command
Could you use dosemu and do whatever it is you need
done on the linux box?
Have the user upload the file to be processed as part

I appreciate the advice...I will consider all these things and the high risk and then pursue the most appropriate way to go about this program...thanks for the help...The users machines are locked down in such a way that they cannot access this site anyway so it does reduce the risk...this site will only be accessable by certain people with permission to access this site so it will be administered properly and not just thrown out for everyone to access...Thanks for everyone's answers again..
