Use zcat and sed or awk to edit compressed .gz text file

Question

I am trying to edit compressed fastq.gz text files, by removing the first six characters of lines 2,6,10,14... I have two different ways of doing this right now, either usin

Answer 1

I wrote a script called zawk which can do this natively. It's similar to glenn jackman's answer to a duplicate of this question, but it handles awk options and several different compression mechanisms and input methods while retaining FILENAME and FNR.

You'd use it like:

zawk 'awk logic goes here' log*.gz

This does not address sed's "in-place" flag (-i).
