The table below compares the operating system commands of Windows, UNIX, VMS and CMS. If you

know one operating system and need to learn another, this type of guide can be very helpful. If you need

help with operating system commands, contact the HelpDesk at 974-9900. If you need assistance with

statistical, graphical, mapping or related research computing, contact the Statistical Consulting Center
