# prozilla(1)

a download accelerator for GNU/Linux

## NAME

**ProZilla** - a download accelerator for GNU/Linux

## SYNTAX

**proz** \[OPTIONS\] \<URL\>

## DESCRIPTION

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

ProZilla is also 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 site, or ask the user to choose one.

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

## OPTIONS

- **-r**

  Resume an interrupted download

- **-f, --force**

  Never prompt the user when overwriting files

- **-1**

  Force a single connection only

- **-s, --ftpsearch**

  Invokes prozilla to do a ftp search for other sites

- **-n, --no-netrc**

  Don't use ~/.netrc, get the user/password from the command line, otherwise use the anonymous login FTP sessions

- **-L, --license**

  Display software license

- **-h, --help**

  Give some help

- **-v, --version**

  Display version number

## FTP OPTIONS

- **--use-port**

- **-s --ftpsearch**

  Invokes prozilla to do a ftp search for other sites

## DOWNLOAD OPTIONS

- **-k=n**

- **--timeout=n**

  Set the timeout for connections to n seconds (default 180)

- **-t, --tries=n**

  Set number of attempts to n (default (30), 0=unlimited)

- **--retry-delay=n**

  Set the time between retries to n seconds (default 10 seconds)

## 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 server or a user-chosen site

- **proz -s -k=10 \<URL\>**

  invokes ftpsearch and will download from the fastest server or a user-chosen site using 10 connections

## FILES
