Cron Task Scheduler — Schedule Python Scripts Without Cron Syntax

Schedule any shell command with simple human-readable intervals. No cron syntax, no systemd timers, no cloud dependencies.

WHAT IT DOES

• Add recurring tasks — schedule commands with simple intervals (5m, 1h, daily)

• List all tasks — see what's scheduled, last run time, and status

• Run manually — trigger any task immediately for testing

• Remove tasks — clean up when done

• JSON-based storage — all tasks saved in ~/.cronman_tasks.json

• Zero dependencies — Pure Python stdlib only

WHAT YOU GET

• cronman.py — The scheduler (Python 3, zero dependencies)

HOW TO USE

python3 cronman.py add backup "python3 ~/scripts/backup.py" --every 1h

python3 cronman.py list

python3 cronman.py run backup

python3 cronman.py remove backup

REQUIREMENTS: Python 3.7+. No pip install needed.

PERFECT FOR: Developers automating repetitive scripts, data engineers scheduling ETL jobs, sysadmins replacing cron, anyone wanting scheduled tasks without cloud dependencies.
