Something like:
bash code:
  1. while IFS='|' read FOOD TYPE ; do
  2.     case $TYPE in 
  3.     meat)
  4.         MEAT=( "${MEAT[@]}" "$FOOD" )
  5.         # MEAT[${#MEAT[@]}]="$FOOD" would work too (see below)
  6.     ;; 
  7.     veg)
  8.         VEG[${#VEG[@]}]="$FOOD"
  9.    ;;
  10.    esac
  11. done <myfile
  12. for element in "${MEAT[@]}"; do
  13.     echo "I really like the meat called $element"
  14. done
  15. for element in "${VEG[@]}"; do
  16.     echo "I really like the vegetable called $element"
  17. done
