Basics of Setting Permissions

• Each file has a set of permissions
• 7 points or bits
• 4-read
• 2-write
• 1-execute
• directory(1) user(3) group (3) world(3)
  • -rwx rwx rwx
  • -rwx --- ---
  • drwx r-x r-x
• To protect your work: chmod 700 [directory_name]
  • -drwx --- ---
• chmod 700 [directory_name] : only you can see or or change any files in that directory
