Run multiple bot telegram bot clients using gnu-screen (terminal-multiplexer). Supply bot tokens via bots.yml to this script. [telethon,telegram,bots.gnu-screen,screen,multiples]

#run_multi.md

First of all you make a bot whose multiple instances are to be run from the same server.

Suppose the bot is run by invoking main.py with the bot_name and token as command line arguments.

Syntax:

[PYTHON] [ENTRY_POINT] [bot_name] [token]

Example:

python main.py mysamplebot "173453434:42jhs894_13234jsjgasjs"

Now the multi_bot.py script runs multiple instances of the bot code in seperate screen sessions/sockets. (each socket is named after the name of the bot running inside it)

The bots.yml file supplies the list of bot accounts with their tokens to multi_bot.py

Syntax of bots.yml

botusername: "bottoken"
anotherbotname: "anothertoken"

Example:

mysamplehorriblebot: "173453434:42jhs894_13234jsjgasjs"
anotherSamplebot: "556453434:42jhs894_13234yuweeerasjs"

run_multi.py

# pip install pyyaml

import yaml
import os

PYTHON = 'python3.9'
ENTRY_POINT = 'main.py'

with open('bots.yml') as file:
    bots = yaml.full_load(file)

for bot_name, token in bots.items():
    command = f'''screen -dmS {bot_name} bash -c '{PYTHON} {ENTRY_POINT} {bot_name} "{token}" ' '''
    os.system(command)
    print(f'deployed @{bot_name}')
