Minimal bash script to push messages to telegram via bot API

tg_notify.sh

#!/bin/bash
# 1. create a bot using @BotFather
# 2. create a public channel, add the bot as it's administrator
# 3. fill in the required information below
# 4. do a test run. In the response there will be a chat_id, which is a bunch of numbers
#    now it's possible to make the channel private and use chat_id instead of the public name

bot_token=#YOUR_BOT_TOKEN
chat_id=#UR_CHANNEL_ID
api_call="https://api.telegram.org/bot$bot_token/sendMessage"
curl \
	--data-urlencode "chat_id=$chat_id" \
