How to make AWK process an input file many many times?
By "many many times" I mean the times the input file is to be processed is unknown beforehand, it will be known when awk finishes processing the input file for the first time.
So my question is: how to start over again from the first record of the input file when AWK finishes processing the last record(before reaching "END")?
