🌐 Download Now

📝 Project Overview

better-crontab protects your crontab commands. It helps avoid accidental deletions when using crontab -e (edit) or crontab -r (delete). These commands can remove your scheduled tasks unintentionally. This software adds a layer of safety by asking for confirmation before these actions.

⚠️ Problem Explanation

In Linux systems, the crontab command has important options:

crontab -e: Edit the current user’s crontab file.
crontab -r: Delete the entire crontab file without confirmation.
crontab -l: List the content of the current user’s crontab.

Main Risks:

Adjacent Keys: The e and r keys are next to each other on a QWERTY keyboard.
No Confirmation: Using crontab -r directly deletes your work without asking.
No Recovery: Once deleted, all scheduled tasks vanish instantly.

✨ Features

✅ Asks for user confirmation before executing crontab -r.
✅ Provides clear warning messages to prevent mistakes.
✅ Fully compatible with all other native crontab features.
✅ Lightweight script with no extra dependencies.
✅ Supports Traditional Chinese interface.
