Bulk file downloader on any topic.

content-downloader

Python package with command line utility to download files on any topic in bulk.

Features

• ctdl fetches file links related to a search query from Google Search.

• Files can be downloaded parallely using multithreading.

• ctdl is Python 2 as well as Python 3 compatible.

Installation

• To install content-downloader, simply,

$ pip install ctdl

• There seem to be some issues with parallel progress bars in tqdm which have been resolved in this pull. Until this pull is merged, please use my patch by running this command:

$ pip install -U git+https://github.com/nikhilkumarsingh/tqdm

Command line usage

$ ctdl [-h] [-f FILE_TYPE] [-l LIMIT] [-d DIRECTORY] [-p] [-a] [-t] [query]

Optional arguments are:

• -f FILE_TYPE : set the file type. (can take values like ppt, pdf, xml, etc.)

  Default value: pdf

• -l LIMIT : specify the number of files to download.

  Default value: 10

• -d DIRECTORY : specify the directory where files will be stored.

  Default: A directory with same name as the search query in the current directory.

• -p : for parallel downloading.

Examples

• To get list of available filetypes:

$ ctdl -a

• To get list of potential high threat filetypes:

$ ctdl -t

• To download pdf files on topic ‘python’:

$ ctdl python This is the default behaviour which will download 10 pdf files in a folder named ‘python’ in current directory.

• To download 3 ppt files on ‘health’:

$ ctdl -f ppt -l 3 health

• To explicitly specify download folder:

$ ctdl -d /home/nikhil/Desktop/ml-pdfs machine-learning

• To download files parallely: $ ctdl -f pdf -p python

Usage in Python files

from ctdl import ctdl

filetype = 'ppt'
limit = 5
directory = '/home/nikhil/Desktop/ml-pdfs'
query = 'machine learning using python'

ctdl.download_content(query, filetype, directory, limit)

TODO

• [X] Prompt user before downloading potentially threatful files

• [ ] Implement unit testing

• [ ] Create ctdl GUI

• [ ] Use DuckDuckgo API as an option

Want to contribute?

• Clone the repository

$ git clone http://github.com/nikhilkumarsingh/content-downloader

• Install dependencies $ pip install -r requirements.txt

Note: There seem to be some issues with current version of tqdm. If you do not get expected progress bar behaviour, try this patch:

$ pip uninstall tqdm $ pip install git+https://github.com/nikhilkumarsingh/tqdm

• In ctdl/ctdl.py, remove the . prefix from .downloader and .utils for the following imports, so it changes from: python from .downloader import download_series, download_parallel from .utils import FILE_EXTENSIONS, THREAT_EXTENSIONS to: python from downloader import download_series, download_parallel from utils import FILE_EXTENSIONS, THREAT_EXTENSIONS

• Run the python file directly python ctdl/ctdl.py ___ (instead of with ctdl ___)
