Linux cron tips

🐧

Run `crontab -e` to edit, then paste the expression followed by your command. The "next 5 runs" preview verifies your schedule.

💡

Be careful with PATH — cron uses a minimal environment. Always use absolute paths in scripts called by cron.

🎯

For debugging cron failures, redirect stdout and stderr: `* * * * * /path/to/script >> /var/log/myscript.log 2>&1`.
