Day 10

Notes

• Surprisingly (?) crontab -l and sudo crontab -l didnot have any scheduled tasks.
• Looked at default crontab in /etc/crontab. And only /etc/cron.daily had scripts in it, cron.hourly, weekly, monthly were empty.
• Scripts like /etc/cron.daily/apt-compact, update-notifier-common were easy to read unlike others.
• Saw systemctl list-timers --all

Readings

• Job scheduling with cron and at
• A good overview of systemd/Timers
• How to Use Systemd Timers as a Cron Replacement
