Hi! I'm doing bash shell scripting and would like to know if bash had something similar to perl's split function? Ultimately, I want to split two strings (delimeter = '.') and compare each of their values. Thus, I figured putting them in an array would be easiest.

So i.e.:

String 1: 21.14.51
String 2: 20.15.21

I want to get:

Array1: [21][14][51]
Array2: [20][15][21]

So that I can run a for-loop to compare the values. Does anyone recommend any other method for doing this?
