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.

You don't need
cut
at all, just baregrep
is enough in the form:Remove any variable you don't want to grep at the time (but leave separators
:
, and begining and end of line signs^
and$
(for edge variables)).For example to grep those with
count=20
:grep those with
count=20
andcost=2
