I’m a complete newbie to awk and am wondering how to process information as following:
mapping.txt:
80 001 002
81 011 012 013 014
82 021 022
...
input.txt:
81 103823044
80 103823054
81 103823064
...
Desired output.txt:
103823044|011|
103823044|012|
103823044|013|
103823044|014|
103823054|001|
103823054|002|
103823064|011|
103823064|012|
103823064|013|
103823064|014|
I’ve done simple mapping wherein the column numbers are fixed but I’m unsure of how to map a dynamic number of columns to the desired output
