Accessing SAS on willow

• Willow is Unix server housed in the data center
  building
• Willows operating system is Sun Solaris (Solaris

• Willow is primarily used by researchers that have
  large number crunching programs
• Limited knowledge of Unix system is needed to run
  SAS

A Few Useful Unix Commands

• cat --- for displaying a file
• cd --- change directory
• cd 1--- to move to sub-directory 1 so on
• cp --- for copying files
