ProZilla — a download accelerator for GNU/Linux

Syntax

proz [Options] <URL>

Description

ProZilla is a download program that makes multiple connections and downloads a file in multiple parts from different servers simultaneously, thus enhancing the download speed and downloading the file faster than a download with a single connection.

ProZilla is able to do ftp searches for other possible sites that contain the same file, ping them for connection speeds and automatically download from the fastest sites.

FTP passwords can be specified with the URL, or can be obtained automatically from ~/.netrc if it exists.

Options

-r, --resume
Resume an interrupted download
-f, --force
Never prompt the user when overwriting files
-1
Force a single connection only
-n, --no-netrc
Don't use .netrc, get the user/password from the command line, otherwise use the anonymous login for FTP sessions
--debug
Log debugging info to a file (default is debug.log)
-v,--verbose
Increase the amount of information sent to stdout
--no-curses
Don't use the Curses interface, but the traditional plain text interface

Examples

proz <URL>
ProZilla will connect to that server and download the file using the default settings
proz -1 <URL>
ProZilla will connect and download the file in 1 part only
proz -s <URL>
invokes ftpsearch and will download from the fastest servers
proz -s -k=10 <URL>
invokes ftpsearch and will download from the fastest servers using 10 connections

Gentoo Example

FETCHCOMMAND='/usr/local/bin/proz --no-curses --min-size=500 --no-getch -s ${URI} -P ${DISTDIR}'
can be placed in /etc/make.conf to use ProZilla to download your system updates. This example will not do FTP searches for files < 500Kb, uses the text interface (handier with portage) and saves the files in your ${DISTDIR} (normally /usr/portage/distfiles)

Files

"/etc/prozilla.conf"
The global config file
"~/.prozrc"
The per-user config file
"~/.netrc"
A file which can be used to provide ProZilla with hosts, accounts and passwords
