How do I sort two arrays using awk?
Hi

How do I sort two arrays in a ascending order? I'm just doing this to teach myself a book my dad got me on unix.

The arrays are A[i] and B[i] and both are including values taken from a file input by the user.

How do I arrange the contents of both arrays so that they are both ordered from lowest to highest? Array A contains the user's age, and B contains their corresponding grade level (1-12).

How do I make it so the contents of the arrays are read as integers and how do I order them?

Thanks

The easiest would be to sort the input file first. See man sort.

Input file is

Age: 14 Grade: 8
Age: 16 Grade: 10
Age: 11 Grade: 6

Its like that. I'm just trying to figure out how to get the Age array sorted from lowest to highest, and same with age.
