Telegram Bot with Automatic Download

This Telegram Bot, based on the Telethon client, is designed to automatically download multimedia files sent to it. Additionally, it now has the capability to download videos or audios from YouTube and direct links to files via their URL.

What's new in this version:

• File Organization:

  • Downloaded files are sorted into folders based on their extension.
  • Downloaded files can be organized into folders based on their name using regular expressions.
  • Files forwarded from groups are stored in specific folders identified by the group ID, allowing for more precise and customized organization (configurable in the .ini file).

• Extended Functionality:

  • Added the ability to download files via links.
  • Implemented file renaming, zip, and rar file decompression features.
  • Introduced the capability to download YouTube videos or audio.
  • Enabled support for multiple languages in bot messages.
  • Introduced options to set permissions for downloaded and bot-generated folders and files.
  • Added functionality to set paths for downloaded YouTube audios and videos.

Generating Telegram API keys

Before working with Telegram's API, you need to get your own API ID and hash:

1. Go to https://my.telegram.org/ and login with your phone number.

2. Click under API Development tools.

3. A Create new application window will appear. Fill in your application details. There is no need to enter any URL, and only the first two fields (App title and Short name) can currently be changed later.

4. Click on Create application at the end. Remember that your API hash is secret and Telegram won't let you revoke it. Don't post it anywhere!

Creating a Telegram Bot

1. Open a conversation with @BotFather in Telegram

2. Use the /newbot command to create a new bot. The BotFather will ask you for a name and username, then generate an authorization token for your new bot.

   The name of your bot is displayed in contact details and elsewhere.

   The Username is a short name, to be used in mentions and telegram.me links. Usernames are 5-32 characters long and are case insensitive, but may only include Latin characters, numbers, and underscores. Your bot's username must end in ‘bot’, e.g. ‘tetris_bot’ or ‘TetrisBot’.

   The token is a string along the lines of 110201543:AAHdqTcvCH1vGWJxfSeofSAs0K5PALDsaw that is required to authorize the bot and send requests to the Bot API. Keep your token secure and store it safely, it can be used by anyone to control your bot.

Get PUID and PGID in Linux

If you need to obtain the PUID (User ID) and PGID (Group ID) in Linux, you can easily do so with the following commands:

Make sure to replace with the username for which you want to obtain the information. These commands will provide you with the corresponding user and group identifiers.

PUID

id -u <USUARIO>

PGID

id -g <USUARIO>

Example

root@Jonas > id -u nobody
99
root@Jonas > id -g nobody
100
