I used to never give a thought to cron. Now, I think, it's the best thing since sliced bread.
It's one of those simple little software tools that just sits on your hard drive and goes about its work silently in the background with barely a complaint.
Usually, a slew of cron jobs are installed when you install your Linux system. These jobs, rotate log files, clear caches and mail queues.
But cron isn't just for the installers to worry about, it's also a useful tool for you to use in your day-to-day.
Here are five things that can be done with cron:
0 22 * * * rsync -a --delete ~/Maildir/ ~/backup/Maildir/This backs up my Maildir directory to a backup folder at 10 p.m. everyday. The directory
~/backupis symlink to another disk.
Cron is a fantastically flexible tool, think creatively to see how it could help you.
