  • Get order from 10 to last
  • Get all order, except last 10 order
• Create a new folder named 'orders'
• Copy orders.txt file in the orders folder
• Rename orders folder to 'orders_backup'
• We don't need tmp folder, delete a folder named tmp
• We don't need tmp.txt file, delete a file name 'tmp.txt'
• Let's add below orders to the list using nano command
  • American Pizza
  • Italian Pizza
