Cron & Task Scheduling (Cron/Systemd Timers/At)

Stop losing your cron job output to the void

🧩 The Challenge

Everyone thinks their cron jobs are running perfectly until they check the logs three months later and realize the script failed silently for weeks. It is maddening to dig through hundreds of lines just to find out a path wasn’t set or a binary was missing.

💡 The Fix

Pipe your standard output and standard error directly into logger so everything hits the systemd journal properly. It keeps your mess out of the root mail queue and puts it where you can actually grep it.

* * * * * /usr/local/bin/backup_script.sh 2>&1 | /usr/bin/logger -t my-cron-job

⚙️ Why It Works

Using logger forces your cron output into the syslog stream with a specific tag, which lets you filter the journal using standard tools like journalctl. You get instant visibility without setting up a massive mail server just to handle local alerts.

🚀 Pro-Tip: Use -p user.err if you want to highlight errors in color or trigger specific alerts in your monitoring stack.
