wget — The non-interactive network downloader.

Download multiple files

• Create variable that holds all URLs and then using 'BASH for loop' to download all files:

% URLS="http://www.example.com/foo.tar.gz ftp://ftp.example.org/pub/bar.tar.gz"

• Use for loop as follows:

% for u in $URLS; do wget $u; done

• You can also put a list of the URLs in a file and download using the -i option:

% wget -i download.txt

Automating/scripting download process

#!/bin/sh
# wget-list: manage the list of downloaded files

# invoke wget-list without arguments

while [ `find .wget-list -size +0` ]
 do
  url=`head -n1 .wget-list`
   wget -c $url
   sed -si 1d .wget-list
 done

#/bin/sh
# wget-all: process .wget-list in every subdirectory
# invoke wget-all without arguments

find -name .wget-list -execdir wget-list ';'

#!/bin/sh
# wget-dirs: run wget-all in specified directories
# invoking: wget-dirs <path-to-directory> ...

for dir in $*
  do
      pushd $dir
      wget-all
      popd
  done
wget-all
