awk aoc 2021

got caught in the thrill of wanting to solve the puzzles fast :)

advent of code 2021: awk

the NUM.awk and NUM_2.awk files are the original ones written under pressure. the *_new.awk files are improved versions written afterwards.

you can see the puzzles and get the input files at advent of code 2021

run

to run a program, e.g. 01.awk:

awk -f 01.awk inputfile

if using gawk, you should be able to use compatibility/traditional mode (except for day 03, and 09)

awk -c -f 01.awk inputfile
