Hello All,

Let's say i have the Following,

Vegetable=Potato ( Kind of vegetable that i have )

Potato=3 ( quantity available )

If i wanna know how many vegetables i have (from a script where i have access only to variable Vegetable), i do the following:

Quantity=${!Vegetable}

But let's say i take one Potato then i want to update the quantity, i should be able to do the following:

${Vegetable}=$(expr ${!Vegetable} - 1)

It does not work !!

Any clues to realize this

Thanks
