Downloader ChRIS Plugin

pl-download is a ChRIS plugin which downloads files from URLs.

Usage

pl-download has two modes: "single" mode (as a fs-type plugin), or "bulk" mode (as a ds-type plugin).

"Single" Mode

In "single" mode, pl-download downloads a file from one URL and writes it to the output directory.

apptainer exec docker://ghcr.io/fnndsc/pl-download:latest downloader --url https://upload.wikimedia.org/wikipedia/commons/d/d1/Rubin_Observatory_and_Its_Target.jpg outputdir/

"Bulk" Mode

In "bulk" mode, pl-download scans an input directory of files where each file contains a list of URLs separated by whitespace.
