pwget = Parallel WGET

Similar to wget, but in parallel

Ever downloaded large files over internet, but connection often resets? Ever want to download in parallel using simple command like wget?

You have it now.

Installing...

$ go install github.com/wushilin/pwget@latest

After this, you will find pwget executable in your $GOPATH/bin. You can add this to your $PATH, or invoke with full path.

What is a jump host?

Jump host is a tool I wrote (similar to proxy, but light weight, secure by default). Checkout https://github.com/wushilin/netjumper

Features of pwget

Simple

# Download with 10 slices
$ pwget http://some-host.download.com/super-large.iso

# Download with 50 slices
$ pwget -n 50 http://some-host.download.com/super-large.iso

# With cookie
$ pwget -c "abc=def; other=sucks;" http://some-host.download.com/super-large.iso

# with referer
$ pwget -r "http://some-host.download.com" http://some-host.download.com/super-large.iso

# with User-Agent
$ pwget -ua "Some-Weird-Broser-String" http://some-host.download.com/super-large.iso

# Specify output file
$ pwget -o small.iso http://some-host.download.com/super-large.iso

# with custom header
$ pwget -H "someHeader: headerval" -o small.iso http://some-host.download.com/super-large.iso

# use with some jumper
$ pwget -j "jumpHost:9527" -k "secret" -H "someHeader: headerval" -o small.iso http://some-host.download.com/super-large.iso

Note that if jumper can't be connected, it will fall back to normal dialer (e.g. direct connection)

# use with quiet (no progress reporting)
$ pwget -q -H "someHeader: headerval" -o small.iso http://some-host.download.com/super-large.iso

Sample output

root@master /o/G/s/g/w/pwget# ./pwget -j home.myhome.net:9527 -k bigsecret "http://releases.ubuntu.com/18.04.1/ubuntu-18.04.1-desktop-amd64.iso?_ga=2.191772394.1990563598.1542159661-244726927.1539156732"
Quiet? false
Size 1953349632 Bytes, file name ubuntu-18.04.1-desktop-amd64.iso
Each segment 195334963 Bytes
Progress: 168057KB of 1907568KB (8%)

Resume capable

The program aborts only after 10 consecutive retries (with 5 seconds sleep inbetween retries) failed to download a single byte. The program resumes download from last abortion (based on file part size), however if you used -n to specify threads, the n must be the same otherwise this download may create corrupted file

Note: If server doesn't support Content-Length response header, the program will not download.

Enjoy!
