## Overview

This is a small command-line downloader: the user supplies a line-by-line file of SpringerLink book URLs, runs the Bash script, and receives downloaded PDF files. The README documents URL processing and downloading, and names curl, sed, lynx, grep, and head as dependencies. Source excerpts were unavailable, so the internal stages and their wiring are shown only at the level supported by that documentation.

Main entry points: [`download.bash`](https://github.com/rahuldeo2047/springerlink_open_file_downloader/blob/master/download.bash) (Downloader script)
