Welcome to the forum.
It is always beneficial to post the OS and shell version you are using as well as tools and their versions (e.g. awk, sed, ...) available.
This is not a new request; it might be worthwhile to search these fora for similar problems to get a starting point for your special solution. Any attempts/ideas/thoughts from your side? Do you have any preferences as for the tools to be deployed? Sample input and output data would help as well!

INTRO(1) BSD General Commands Manual INTRO(1)
NAME
intro -- introduction to general commands (tools and utilities)
DESCRIPTION
Section one of the manual contains most of the commands which comprise the BSD user environment. Some of the commands included in section
one are text editors, command shell interpreters, searching and sorting tools, file manipulation commands, system status commands, remote
file copy commands, mail commands, compilers and compiler tools, formatted output tools, and line printer commands.
All commands set a status value upon exit which may be tested to see if the command completed normally. Traditionally, the value 0 signifies
successful completion of the command, while a value >0 indicates an error. Some commands attempt to describe the nature of the failure by
using exit codes as defined in sysexits(3), while others simply set the status to an arbitrary value >0 (typically 1).
