GET_CHUNK

About

This utility is used to retrieve the fragment from a file. ( I've created this tool for my personal use, aimed at extracting specific snippets from a generic CHANGELOG file :D )

Example

```bash

text from CHANGELOG.md

# Changelog

## [2.0.0] - xxxx-xx-xx

### Added

- text text text text from version 2.0.0

# [1.0.0] - xxxx-xx-xx

### Added

- text text text text

getchunk --read-from "./CHANGELOG.md" --start-str "## [\d.\d.\d]" --write-to "tempchangelog.md"

Output

## [2.0.0] - xxxx-xx-xx

### Added

- text text text text from version 2.0.0

```

```bash Retrieve the fragment from the file
