Telert – Telegram/Slack/Desktop alerts when your terminal commands finish

#cli #devops #python #productivity

Hi everyone,

I recently built a small open-source tool called Telert.
It helps you get notifications when your terminal commands or Python scripts finish running — useful when you run long processes and don't want to keep checking the terminal.

I built it for myself initially, but realized it might help others too!

What Telert Does

Works as a command-line utility and a Python hook
Sends notifications via Telegram, Slack, Teams, desktop notifications, or audio alerts
Customizable messages with status codes (success, failure, etc.)
Hooks to auto-notify if a command runs longer than a set time
Cross-platform install via pip: Linux, macOS, Windows

Quick Install

Install Telert via pip:

pip install telert

Set up your channels easily:

telert config audio
telert config telegram --token "<token>" --chat-id "<chat-id>" --set-default

Track your long running commands

sleep 5 | telert

You'll get an alert when the command completes!

Example Use Cases

Monitor long-running ETL jobs and get notified when they complete
Receive Telegram or Slack alerts after server updates, backups, or cronjobs finish
Track the completion of machine learning model training or batch predictions
Get desktop notifications after code compilation, testing, or Docker builds during development
Get notified if any command takes longer than a set time
