Persistent-Memory gawk User Manual

Next: , Up: (dir)  

General Introduction

gawk 5.2 introduces a persistent memory feature that can “remember” script-defined variables and functions across executions; pass variables between unrelated scripts without serializing/parsing text files; and handle data sets larger than available memory plus swap. This supplementary manual provides an in-depth look at persistent-memory gawk.
