EPICS Installations @ GSI: Directory Setups

• Nomenclature

file

link to a file

directory

link to a directory

• /usr/local/bin
  • contains (soft) links to <GSI's EPICS Installation Top Directory>/bin/
    
    • where at the moment:
      • <GSI's EPICS Installation Top Directory> is ~epics
    • but will be:
      • /usr/local/pub
  • linked files
    • epics
      
      

• <GSI's EPICS Installation Top Directory>
