Description

Inspired by OPM-Scraper.

BashPunchMan is a Bash script automation tool for downloading One-Punch Man manga chapters from the r/OnePunchMan subreddit and packaging them into CBZ (Comic Book Archive) format files. It downloads any chapter not found in the target folder and creates a .cbz (.zip) named the same as the chapter.

I created this with the intention to use it with Kavita but any reader that can handle .cbz should do.
