Arrays (The GNU Awk User’s Guide)
8 Arrays in awk
An array is a table of values called elements. The elements of an array are distinguished by their indices. Indices may be either numbers or strings.
This chapter describes how arrays work in
awk, how to use array elements, how to scan through every element in an array, and how to remove array elements. It also describes how
awk simulates multidimensional arrays, as well as some of the less obvious points about array usage. The chapter moves on to discuss
gawk’s facility for sorting arrays, and ends with a brief description of
gawk’s ability to support true arrays of arrays.
