Cron & Task Scheduling (Cron/Systemd Timers/At)
Stop losing your sanity when cron sends emails to nobody
🧩 The Challenge
You finally realize your backup job has been failing silently for three days, but cron just dumped the error output into a black hole or a local mailbox you never check. Nothing is worse than finding out your data isn’t safe because you didn’t have eyes on the job’s failure.
đź’ˇ The Fix
Point the output directly to a dedicated log file or a tool that actually sends alerts, so you don’t have to go digging through dead local mail queues. This way, you’ll see the carnage the second it happens.
* * * * * /path/to/script.sh >> /var/log/my_cron_jobs.log 2>&1⚙️ Why It Works
Adding that 2>&1 bit redirects the standard error stream into the standard output stream, making sure your stderr chatter actually ends up in the same log file as the rest of your process output.
🚀 Pro-Tip: If you’re on a modern system, just use systemd timers; they handle logging to journald automatically and save you from the headache of cron’s lack of observability.
