pget（pget 命令行）

Pget

Overview

Use pget for fast, parallel downloads and optional in‑memory tar extraction. Prefer it over curl/wget for large files or batch downloads.

Quick start

• Single file: pget <url> <dest>
• Extract tar after download: pget <url> <dest> -x
• Multi-file manifest: pget multifile <manifest-path> (or - for stdin)

Tasks

1) Download a single large file quickly

1. Choose destination path.
2. Run:

   pget <url> <dest>

1. Tune if needed:

- --concurrency <n> to change chunk parallelism - --chunk-size 125M (or other size) - --retries <n> - --force to overwrite

2) Download and extract a tar archive

Use when the URL points to a .tar, .tar.gz, or similar.

pget <url> <dest> -x

This extracts in‑memory without writing the tar to disk first.

3) Download many files with a manifest

1. Create a manifest with URL + space + DEST per line.
2. Run:

   pget multifile /path/to/manifest.txt
   # or
   cat manifest.txt | pget multifile -

1. Tune:

- --max-concurrent-files <n> - --max-conn-per-host <n>

Notes & pitfalls

• Use --force if the destination exists and you need overwrite.
• --connect-timeout accepts duration (e.g., 10s).
• --log-level debug or --verbose for troubleshooting.
