Home / Naruto downloader script

If, as me, you like Naruto, this script is perhapse for you !
The script will scan bakasan.net every couple of minutes and search if the new episode is out, and download it automatically if yes !
Naruto is a funny and distractive manga I like. BakaSan is a team of translators who provides an english version of Naruto. Download the serie is legal in some cuntrys, because of a lack of deposed copyrights in them.

Requierments

You need to download and install BitTorrent.
Normaly, lynx, grep and awk are installed with your distribution : they are needed for the script.

How to use

First, create a file "~/naruto_downloader.bash" for exemple and paste the code below.
Make the file executable. With the command chmod +x ~/naruto_downloader.bash. Or by file Properties / Permitions / "Is executable" in a grapic desktop.
That's all : all times you have a new episode to download, just run ~/naruto_downloader.bash 79, where 79 is the number of the soon available episode !
By default, the episode will be saved in your home directory, with name "~/[BakaSan]_Naruto_$number.avi". You can edit the script and change the variable target. You also can change time to set a different wait time between tries.

The script

#!/bin/bash
#naruto_downloader.bash

# This script download the last espisode of Naruto from [BakaSan]
#  as soon as it is out (few minutes)

# Episode to download
#  $# : Number of arguments given to the script
#  $1 : 1° argument given to the script
if [ $# != 1 ]; then
  echo "Usage : $0 episodeNumber"
  exit 1;
fi
number=$1

##
## You can configure those two parameters :
##

# Target file where to save the downloaded episode :
target=~/[BakaSan]_Naruto_$number.avi
# Wait duration (in minutes) between each trys :
time=5

echo "Wait for download Naruto episode #$number..."

# Try while episode isn't available yet
while ((1)); do
  # Download the home page where is the bittorrent link
  #  `lynx --dump` return HTML page from lynx
  #                AND add a section References at the end
  #                with all links " 1. http://..."
  #  A grep allow to get the link with the number of the
  #   episode to download
  link=`lynx --dump "http://www.bakasan.net/" | grep -E '[0-9]+\. .*'$number`

  # Get the bittorent link (2° field of " 1. http://...")
  link=`echo $link | awk '{print $2}'`

  # -z : empty
  # -n : not empty
  if [ -z "$link" ]; then
    # Cf below for explanation of this line
    echo `uptime | cut -d " " -f 2 | cut -d ":" -f "1 2" --output-delimiter "H"`" - :-("
    # The last Naruto isn't out yet :
    #  We wait $time minutes before to retry
    sleep $(($time*60))
  else
    # Get the current time
    #  uptime : " 19:50:30 up  4:23,  1 user,  load average: 0.37, 0.22, 0.15"
    #  1° cut : "19:50:30" (column 2)
    #  2° cut : "19H50"    (column 2 and 3 with "H" as output separator)
    heure=`uptime | cut -d " " -f 2 | cut -d ":" -f "1 2" --output-delimiter "H"`
    # Beep to avert user the begin of the download
    echo $'\a'
    # And display wanted informations
    echo "$heure - The last Naruto is available. Download of :"
    echo "$link"
    # Finaly, begin the download
    btdownloadgui.py $link --saveas $target
    # That's all (we hope) : quit the script
    exit
  fi
done
