Lets say I'm doing a database for fruits. Using a text file for it, inside contains, in this format,
(Fruit:Quantity:Cost) Apple:10:1 Orange:20:2 Pears:10:3 Banana:20:4 10 Apples at $1 each. 20 Oranges at $2 each. 10 Pears at $3 each. 20 Bananas at $4 each.
My simple script goes like this:
echo "Enter fruit to find" read fruit echo "Enter quantity to find" read count echo "Enter cost to find" read cost grep $fruit FruitDB.txt
It will display the fruits in the database.
But how do i use grep and cut together to find just by the quantity or the cost. In the quantity count area, let's say i enter 20, it will display the Oranges and Banana. Or when i enter count and cost, it will display just those that meet the conditions.
