My shell script that I have so far is

Code:
top_veg_cost=$(cat -n Thanksgiving/Loaded_Mashed_Potatos/Ingredients.csv Thanksgiving/Meat_Loaf/Ingredients.csv Thanksgiving/Pumpkin_Pie/Ingredients.csv | grep vegatable)

echo "$top_veg_cost"

out come I have so far is

Code:
     1  Potato,vegatable,0.89,5
     4  green_onion,vegatable,0.99,3
    11  onion,vegatable,0.89,2
    12  bell_pepper,vegatable,0.89,2
    21  pumpkin_pie_filling,vegatable,2.98,1

when I add a sort command to the script like this

Code:
top_veg_cost=$(cat -n Thanksgiving/Loaded_Mashed_Potatos/Ingredients.csv Thanksgiving/Meat_Loaf/Ingredients.csv Thanksgiving/Pumpkin_Pie/Ingredients.csv | grep vegatable | sort -t, +2 -3n)

echo "$top_veg_cost"

new out come is

Code:
    11  onion,vegatable,0.89,2
    12  bell_pepper,vegatable,0.89,2
     1  Potato,vegatable,0.89,5
     4  green_onion,vegatable,0.99,3
    21  pumpkin_pie_filling,vegatable,2.98,1


I have no idea what command I should add to get the 2 highest cost vegetables which are

Code:
 21  pumpkin_pie_filling,vegatable,2.98,1 
  4  green_onion,vegatable,0.99,3
