send stuff to telegram bot command-line globally

preface

As you have seen in the other posts, I like to use a telegram bot for my notifications with domoticz. But I also like to use it to notify me from scripts.

After a while I found myself adding the same long ‘curl etc etc’-commands in every script, so it was time to create a little script that holds everything I need and can be used globally.

prerequisites

You need to have a telegram bot already up and running. Like earlier is found this tutorial to be pretty good.

code

create a new file called ‘tg’ and ‘chmod +x’ it. Then edit it like so:

#!/bin/bash
bot_id="insert your bot id here"
api_key="your api-key here"
chat_id="your chat-id here"
action="sendMessage"
curl -s "https://api.telegram.org/$bot_id:$api_key/$action?chat_id=$chat_id&text=$1"

After that create a symlink to ‘/bin/tg’. Because ‘/bin’ is usually in the ‘search path’ for commands it will be accessible from everywhere.

result

now you can use it ‘globaly’ from scripts or command line:

root@host:/$ tg "blabla bla"

And it will send your text to your Telegram bot:
