get

A multi-connection file downloader using parallel HTTP range requests. Downloads are resumable and multiple mirror URLs can be used at once.

Flags:
  -h, --help                Help for get
  -o, --output string       Output file to <filename>
  -p, --procs int           The number of connections for a single URL (default 1)
  -r, --referer string      Identify as <referer>
  -t, --timeout int         Set timeout of checking request in seconds (default 10)
  -u, --user-agent string   Identify as <agent>
  -v, --version             Version for get

Install

Build from source (requires Go 1.27.1+):

go install github.com/setanarut/get/cmd/get@latest

Usage

Download a file with 4 connections:

get -p 4 https://example.com/file.zip

Save to a specific path:

get -o ./downloads/file.zip https://example.com/file.zip

Download from multiple mirrors at the same time:

get -p 2 https://mirror-a.com/file.zip https://mirror-b.com/file.zip

URLs can also be passed through stdin, one per line.

Resume

If a download is interrupted (CTRL+C), run the same command again. The downloaded chunks are stored in a _<filename>.partial directory next to the output file and reused on the next run.

> get https://example.com/file.zip

Because chunks are stored by their byte offset, you can resume with a different -p value and the already downloaded data is still reused.

Notes

• The server must support HTTP range requests (Accept-Ranges: bytes).
• Using many connections to a single URL can put load on the server. In most cases 4 or fewer is enough.
